This document discusses using fingerprints to identify infants and toddlers in order to improve vaccination coverage rates. It summarizes previous research on using different biometric traits for infant identification and explains why fingerprints were selected. It then describes the authors' data collection process, where they captured fingerprint images of 90 infants and toddlers in the US and Africa over multiple sessions. Their goal is to evaluate the feasibility of using fingerprints to uniquely recognize children and link them to their vaccination records.
Service Tax Voluntary Compliance Encouragement Scheme, 2013 (VCES)Experts & Chartered
The Voluntary Compliance Encouragement Scheme, 2013 (VCES) allows service providers to settle outstanding service tax liabilities for the period from October 2007 to December 2012 without penalties. Eligible taxpayers must have no pending inquiries or orders and must file a declaration by December 2013. Taxpayers must pay declared taxes using Form VCES-1 and will receive an acknowledgement of discharge within 7 days of payment using Form VCES-3. While the acknowledgement is generally conclusive, the tax authority can reopen the case within 1 year if the declaration was substantially false. The scheme aims to encourage voluntary compliance in the service tax sector.

Introduction
Immunization is the process in which an individual is protected against disease, and it is done via vaccination. On the other hand, vaccination is the action of a vaccine being introduced into the body to produce immunity to a particular disease. A vaccine is a product that arouses the immune system of an individual, thus the production of immunity to a particular disease. The immunity thus protects the individual from that disease. Immunity is the protection from a disease that is infectious. Child immunization is the primary public health approach in the reduction of child mortality and morbidity. Assessment of the current approaches that are linked to the immunization of a child is essential. Globally, primary immunization is estimated to prevent approximately 2.5 million childhood deaths annually from tetanus, diphtheria, measles, and pertussis (Dube et al., 2013). Immunization succession is always accompanied by rejection of public health practices, and reasons for these have never been straightforward. Some of the motivations are religious, scientific, or even political. To reduce the incidence and prevalence of vaccine-preventable diseases, vaccination programs depend on a high uptake level. Vaccination offers protection for vaccinated individuals. When there are high vaccination coverage rates, the indirect protection rate is stimulated for the overall community (Dube et al., 2013).Literature Review
Despite this massive use, immunization coverage in countries still developing has been reported to be still low. If mothers were educated on the importance of these vaccine services to their children, all the children would receive immunization as per the Expanded Program on the Immunization schedule, hence preventing mortality and morbidity. According to Thapar et al., in 2014, approximately an 18.7million children could not get the third dose of the Diphtheria-Pertussis-Tetanus (DPT3) vaccine. The total percentage of children who are one year and below and have to receive their dosses of DPT3 vaccine is seen as a proxy indicator regarding full immunization. The DPT3 estimates assess the health system performance and measure the immunization program effectiveness regarding service delivery. These strategies are thus used in the implementation of strategies for the elimination and eradication of diseases. According to Thapar et al., the global coverage for DPT1 and DPT3 was 90% and 86%, respectively, while that of measles first dose at 86%.
The above estimates thus do not replicate the seen differences in vaccine coverage. The coverage of DPT1 and DPT3 varied ...

This document discusses a study on supporting children's adherence to anti-retroviral (ART) therapy in Malawi. The study followed 47 HIV-positive children on ART over 6 months to a year. 72% of children never missed a dose according to caregiver reports. Clinic attendance was also good, with over 80% of visits either on time or within a week of the scheduled date. Focus groups and interviews with caregivers provided insights into challenges of supporting children's adherence, such as costs of medication and transport as well as caregiver responsibilities, but also motivations like seeing children's health improve. The findings highlight the need for more affordable and less complex ART regimes as well as tools to help caregivers support children's adherence

Jin et al. (2018)published a study that aimed to review the immunization status of cochlear implant recipients, assess if adding a vaccine specialist made a change in vaccine compliance, and elucidate any barriers to vaccine compliance. This study implemented the quantitative approach. Chart review and a telephone survey were used to obtain vaccination status and collect data. The results were that ninety-eight percent of children were vaccinated before surgery as opposed to sixty-seven percent prior to the vaccine specialist consultation. A strength of this study was the inclusion of one hundred and sixteen children. One limitation of this study was the fact that data was collected via a telephone survey. The parents could have been dishonest about whether their child was vaccinated or not.
Kaufman et al. (2017) conducted a study that aimed to define different ways to communicate interventions for routine vaccinations and integrate them into a hierarchy of vaccination communication. The quantitative approach was used. Through a targeted literature search, primary fieldwork observation, and consultations with stakeholders data was collected including inclusion and exclusion criteria. The results of the study were the creation of a hierarchy that is categorized by purpose and outlines communication interventions to address gaps in vaccination education. A strength of the study was that data was collected globally during the literature search. The interventions suggested have not been reviewed for accuracy, therefore, the hierarchy could show gaps in evidence.

This document describes a study that used a Box-Jenkins time series approach to model and forecast reported cases of Vesco Vaginal Fistula (VVF) in Kebbi State, Nigeria from 2004 to 2012. The researchers identified the best-fitting seasonal autoregressive integrated moving average (SARIMA) model for the monthly VVF case data and estimated its parameters. The selected SARIMA (2,0,0)x(1,1,4) model was used to forecast that VVF cases would remain high over the next 24 months if no additional measures were taken. The study recommends enforcing laws around child marriage and reproductive rights to help address factors contributing to high VVF rates in Nigeria.

Background: With the widespread use of highly active antiretroviral therapy, the epidemic of HIV has evolved into a chronic disease. HIV is extremely stigmatizing, resulting in highly emotionally charged responses to disclosure. World Health Organization (WHO) recommends that children should be informed of their HIV status at ages of 6 to 12 years and full disclosure at about 8 to 10 years. Disclosure process is much more difficult when the person being disclosed to is an adolescent. However, disclosure of HIV to a child should be an ongoing process that may last several years depending on the cognitive development of the child.
Methods: This study investigated the determinants of HIV status disclosure among HIV infected adolescents. A total of 209 HIV infected adolescents (10-19 years) who have been on treatment for at least six months, and are taking lifelong anti-retroviral therapy from Bondo County Hospital, Got Agulu and Uyawi Sub County Hospital in Bondo Sub County were enrolled. Simple random sampling was employed in selecting the adolescents. Data was collected using a structured questionnaire. Quantitative data was analysed using both descriptive and inferential statistics while statistical tests including Pearson Correlation analysis and multiple linear regression were used to test the hypotheses.
Results: Findings on the overall parental perceptions regarding risks and benefits of disclosure and disclosure of HIV status to adolescents show that 180 (86.12%) of the respondents had a negative attitude compared to 29 (13.88%) who held a positive attitude. 122 (58.37%) of the respondents believed that overall availability and quality of counselling was moderate. 10 (4.78%) of the respondents believed that the overall availability and quality of counselling was high. Quality services and perception of the parents have been found to be good predictors of disclosure of HIV status among the newly diagnosed adolescents in Bondo sub-County, p-value<0.05.
Conclusion and recommendation: This study identified quality of service and perception of the parents as the two factors determining the disclosure of HIV status. There is a correlation between the parental perceptions regarding risks and benefits of disclosure and the quality of counselling to parental disclosure of HIV status to adolescents. Therefore the study recommends deliberate efforts to ensure quality service delivery and age specific disclosure counselling to caregivers to equip them with adequate knowledge on disclosure.
This document summarizes a study on childhood vaccination rates in Athens, Greece. The study assessed vaccination coverage of 304 preschool and primary school children, identified weaknesses in vaccination programs, and examined the impact of parental socioeconomic factors and attitudes. The results showed vaccination rates were higher than other Greek studies, with 94.8% fully vaccinated for DTP, 99.2% for polio, and 63.3% for MMR. Socioeconomic factors like low parental education and poorly organized family schedules were associated with lower vaccination rates. The study aimed to evaluate vaccination programs and factors influencing coverage in an urban Greek population.

This study aimed to evaluate vaccine literacy in patients with systemic autoimmune diseases. The researchers surveyed 319 such patients about their vaccine literacy skills and related sociodemographic factors. They found that the patients had medium levels of functional and interactive-critical vaccine literacy. Higher interactive-critical literacy was associated with being female, living in an urban area, being widowed, and having a high socioeconomic status. Both literacy scales were highest in patients with a university degree. Understanding factors linked to vaccine literacy can help ensure optimal vaccination rates in this vulnerable patient population.

Introduction
Immunization is the process in which an individual is protected against disease, and it is done via vaccination. On the other hand, vaccination is the action of a vaccine being introduced into the body to produce immunity to a particular disease. A vaccine is a product that arouses the immune system of an individual, thus the production of immunity to a particular disease. The immunity thus protects the individual from that disease. Immunity is the protection from a disease that is infectious. Child immunization is the primary public health approach in the reduction of child mortality and morbidity. Assessment of the current approaches that are linked to the immunization of a child is essential. Globally, primary immunization is estimated to prevent approximately 2.5 million childhood deaths annually from tetanus, diphtheria, measles, and pertussis (Dube et al., 2013). Immunization succession is always accompanied by rejection of public health practices, and reasons for these have never been straightforward. Some of the motivations are religious, scientific, or even political. To reduce the incidence and prevalence of vaccine-preventable diseases, vaccination programs depend on a high uptake level. Vaccination offers protection for vaccinated individuals. When there are high vaccination coverage rates, the indirect protection rate is stimulated for the overall community (Dube et al., 2013).Literature Review
Despite this massive use, immunization coverage in countries still developing has been reported to be still low. If mothers were educated on the importance of these vaccine services to their children, all the children would receive immunization as per the Expanded Program on the Immunization schedule, hence preventing mortality and morbidity. According to Thapar et al., in 2014, approximately an 18.7million children could not get the third dose of the Diphtheria-Pertussis-Tetanus (DPT3) vaccine. The total percentage of children who are one year and below and have to receive their dosses of DPT3 vaccine is seen as a proxy indicator regarding full immunization. The DPT3 estimates assess the health system performance and measure the immunization program effectiveness regarding service delivery. These strategies are thus used in the implementation of strategies for the elimination and eradication of diseases. According to Thapar et al., the global coverage for DPT1 and DPT3 was 90% and 86%, respectively, while that of measles first dose at 86%.
The above estimates thus do not replicate the seen differences in vaccine coverage. The coverage of DPT1 and DPT3 varied from 84% and 76% in Africa and 97% and 94% in the European countries. In India, the routine has been lower than in the rest of the countries. Following the 2013 outbreak in Israel, many paren ...
13 Assessing Current Approaches to Childhood ImmunizatioCicelyBourqueju
This document presents a research proposal assessing current approaches to childhood immunization. The study will use a community-based cross-sectional design to examine factors associated with partial immunization of children under five, such as mothers' knowledge, beliefs, religion, and education level. A sample of mothers will be surveyed using random stratified sampling. Correlation analyses will examine relationships between vaccination hesitancy and demographic factors. The results could help identify digital methods for tracking under-vaccinated children and inform future health policy. Limitations include potential recall bias and the time needed for data collection.

Model for the Prediction of the Reported Cases of Vesco Vaginal Fistula in K...inventionjournals
This document describes a study that used a Box-Jenkins time series approach to model and forecast reported cases of Vesco Vaginal Fistula (VVF) in Kebbi State, Nigeria from 2004 to 2012. The researchers identified the best-fitting seasonal autoregressive integrated moving average (SARIMA) model for the monthly VVF case data and estimated its parameters. The selected SARIMA (2,0,0)x(1,1,4) model was used to forecast that VVF cases would remain high over the next 24 months if no additional measures were taken. The study recommends enforcing laws around child marriage and reproductive rights to help address factors contributing to high VVF rates in Nigeria.

Background: With the widespread use of highly active antiretroviral therapy, the epidemic of HIV has evolved into a chronic disease. HIV is extremely stigmatizing, resulting in highly emotionally charged responses to disclosure. World Health Organization (WHO) recommends that children should be informed of their HIV status at ages of 6 to 12 years and full disclosure at about 8 to 10 years. Disclosure process is much more difficult when the person being disclosed to is an adolescent. However, disclosure of HIV to a child should be an ongoing process that may last several years depending on the cognitive development of the child.
Methods: This study investigated the determinants of HIV status disclosure among HIV infected adolescents. A total of 209 HIV infected adolescents (10-19 years) who have been on treatment for at least six months, and are taking lifelong anti-retroviral therapy from Bondo County Hospital, Got Agulu and Uyawi Sub County Hospital in Bondo Sub County were enrolled. Simple random sampling was employed in selecting the adolescents. Data was collected using a structured questionnaire. Quantitative data was analysed using both descriptive and inferential statistics while statistical tests including Pearson Correlation analysis and multiple linear regression were used to test the hypotheses.
Results: Findings on the overall parental perceptions regarding risks and benefits of disclosure and disclosure of HIV status to adolescents show that 180 (86.12%) of the respondents had a negative attitude compared to 29 (13.88%) who held a positive attitude. 122 (58.37%) of the respondents believed that overall availability and quality of counselling was moderate. 10 (4.78%) of the respondents believed that the overall availability and quality of counselling was high. Quality services and perception of the parents have been found to be good predictors of disclosure of HIV status among the newly diagnosed adolescents in Bondo sub-County, p-value<0.05.
Conclusion and recommendation: This study identified quality of service and perception of the parents as the two factors determining the disclosure of HIV status. There is a correlation between the parental perceptions regarding risks and benefits of disclosure and the quality of counselling to parental disclosure of HIV status to adolescents. Therefore the study recommends deliberate efforts to ensure quality service delivery and age specific disclosure counselling to caregivers to equip them with adequate knowledge on disclosure.
This document summarizes a study on childhood vaccination rates in Athens, Greece. The study assessed vaccination coverage of 304 preschool and primary school children, identified weaknesses in vaccination programs, and examined the impact of parental socioeconomic factors and attitudes. The results showed vaccination rates were higher than other Greek studies, with 94.8% fully vaccinated for DTP, 99.2% for polio, and 63.3% for MMR. Socioeconomic factors like low parental education and poorly organized family schedules were associated with lower vaccination rates. The study aimed to evaluate vaccination programs and factors influencing coverage in an urban Greek population.

This study aimed to evaluate vaccine literacy in patients with systemic autoimmune diseases. The researchers surveyed 319 such patients about their vaccine literacy skills and related sociodemographic factors. They found that the patients had medium levels of functional and interactive-critical vaccine literacy. Higher interactive-critical literacy was associated with being female, living in an urban area, being widowed, and having a high socioeconomic status. Both literacy scales were highest in patients with a university degree. Understanding factors linked to vaccine literacy can help ensure optimal vaccination rates in this vulnerable patient population.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Abstract
One of the major goals of most national, international
and non-governmental health organizations is to eradicate
the occurrence of vaccine-preventable childhood diseases
(e.g., polio). Without a high vaccination coverage in a
country or a geographical region, these deadly diseases
take a heavy toll on children. Therefore, it is important for
an effective immunization program to keep track of children
who have been immunized and those who have received the
required booster shots during the first 4 years of life to im-
prove the vaccination coverage. Given that children, as well
as the adults, in low income countries typically do not have
any form of identification documents which can be used for
this purpose, we address the following question: can finger-
prints be effectively used to recognize children from birth
to 4 years? We have collected 1,600 fingerprint images
(500 ppi) of 20 infants and toddlers captured over a 30-day
period in East Lansing, Michigan and 420 fingerprints of
70 infants and toddlers at two different health clinics in
Benin, West Africa. We devised the following strategies to
improve the fingerprint recognition accuracy when compar-
ing the acquired fingerprints against an extended gallery
database of 32,768 infant fingerprints collected by VaxTrac
in Benin: (i) upsample the acquired fingerprint image to
facilitate minutiae extraction, (ii) match the query print
against templates created from each enrollment impression
and fuse the match scores, (iii) fuse the match scores of
the thumb and index finger, and (iv) update the gallery
with fingerprints acquired over multiple sessions. A rank-1
(rank-10) identification accuracy of 83.8% (89.6%) on the
East Lansing data, and 40.00% (48.57%) on the Benin
data is obtained after incorporating these strategies when
matching infant and toddler fingerprints using a commer-
cial fingerprint SDK. This is an improvement of about 38%
and 20%, respectively, on the two datasets without using
the proposed strategies. A state-of-the-art latent fingerprint
SDK achieves an even higher rank-1 (rank-10) identifica-
tion accuracy of 98.97% (99.39%) and 67.14% (71.43%)
on the two datasets, respectively, using these strategies; an
improvement of about 23% and 24%, respectively, on the
two datasets without using the proposed strategies.
1. Introduction
The United Nations Children’s Fund (UNICEF)’s “2013
Progress Report on Committing to Child Survival: A
Promise Renewed” [2] mentions that while more children
now survive beyond their fifth birthday than ever before,
the poorest nations still lose a large number of children to
vaccine-preventable diseases. The 2011 Grand Challenges
in Global Health Explorations Round 7 issued by the Bill
and Melinda Gates Foundation [4] states that “each year ap-
proximately 25 million infants do not receive the necessary
immunizations1
, and at least 2.4 million children die from
vaccine-preventable diseases.”
With the aim of eradicating vaccine-preventable dis-
eases, routine and mandatory vaccination programs are a
norm in high income countries. For instance, according to
the Centers for Disease Control and Prevention (CDC), “in
the United States, vaccination programs have eliminated or
significantly reduced many vaccine-preventable diseases”
[3]. Consequently, the child mortality rates have reduced
considerably in high income countries. On the other hand,
routine immunization programs have not been as effective
in reducing the occurrence of vaccine-preventable diseases
in low-income countries. VaxTrac2
, a non-governmentalor-
ganization working in West-African countries, states that
the “vaccine wastage rates are higher than 50% in some of
the most challenging geographies”, and “for every $100 in
new vaccines purchased, $50 will never go into the arm of
a child in need”3
. As a result, the child mortality rates con-
tinue to be high in the low-income and developing coun-
tries.
An effective immunization program needs to keep track
of which infants and toddlers have been immunized and
how often they have received the required booster shots
from birth to 4 years of age (Fig. 1 shows the UNICEF

recommended immunization schedule for infants; for CDC
recommended schedule for children upto 6 years see [1]). In
developing countries, typically, there are no national iden-
tification programs which can be used to identify children
throughout the immunization schedule4
. This raises the fol-
lowing question: can fingerprints, or, for that matter any
other biometric modality, be used to identify children from
birth to 4 years of age?
Some efforts have been made to investigate the viabil-
ity of using different biometric traits for identifying infants
and toddlers. In 1899, Sir Francis Galton [11] first studied
the variations encountered in the inked fingerprint impres-
sions of an infant captured over time (from about 9 days
to 4.5 years of age). He concluded that it was not feasi-
ble to identify infants in the age range of 0-2.5 years us-
ing inked fingerprint impressions. More recently, the Joint
Research Center of the European Commission published a
technical report [5] devoted to the question of whether or
not automated fingerprint recognition for children is fea-
sible. The study concluded that (i) children can be iden-
tified using fingerprints when the time difference between
the two captured impressions is less than 4.5 years, and
(ii) image quality is a decisive factor in fingerprint recog-
nition. Gottschlich et al. [12] studied the effect of adoles-
cent growth on the accuracy of fingerprint matching sys-
tems, and showed that (i) fingerprint growth can be mod-
elled using an isotropic growth model, and (ii) matching
accuracy of fingerprint systems can be improved by upscal-
ing the fingerprint images using this model when matching
fingerprint images of adolescents collected over time.
Corby et al. [7] studied the viability of using commer-
cial sensors to capture iris images of 1.5-8 year old children.
They reported a high failure to enroll (FTE) rate of approx-
imately 57%, although the recognition accuracy for the en-
rolled subjects was very high (about 99%). Tiwari et al. [20]
and Bharadwaj et al. [6] captured face images of newborns
(0-3 days old) and concluded that it was difficult to cap-
ture good quality face images due to (i) gross head reflexes,
and (ii) pose and expression variations. Weingaertner et
al. [21] investigated the use of palmprints and footprints
for identifying newborns (0-2 days old). Manual match-
ing accuracy was reported to be approximately 83% and

approximately 67% for palmprints and footprints of new-
borns, respectively. Lemes et al. [15] used a 1000 ppi com-
mercial sensor to capture palmprint images of 20 newborns
(0-2 days old). They reported palmprint recognition accu-
racy of approximately 95%. Pela et al. [17] and Thompson
et al. [19] investigated the use of footprints acquired using
traditional ink on paper methods for identification of new-
borns (0-2 days old) and concluded that footprints cannot
be captured reliably. Kotzerke et al. [13] proposed to use
the creases on footprint for manual identification of infants,
where the footprint images were obtained by ink and paper
acquisition. Two researchers with considerable experience
in ridge-based biometrics correctly classified 19 of the 20
pairs.
Although a number of different biometric modalities for
identifying children have been explored, there is no clear
consensus on (i) whether it is feasible to recognize infants
and toddlers using biometrics, and (ii) if biometric recog-
nition is indeed feasible, which modality is best suited for
this task. Based on a number of considerations such as
ease of capture (palmprints are difficult to capture because
newborns and infants keep their fists closed), parental con-
cerns (e.g., infrared illumination for iris capture), persis-
tence of biometric trait (facial characteristics change over
time), in our opinion, fingerprints appear to be the most vi-
able biometric for infant and toddler recognition (see Tab.
1). Indeed, VaxTrac has developed a mobile vaccine reg-
istry system which uses fingerprints to identify children in
Benin1
(Fig. 2(b)). In the VaxTrac system, the left and right
thumb prints of both the child and his mother are collected.
If the child’s fingerprints cannot be matched successfully,
mother’s fingerprints are used for establishing/verifying the
child’s identity. While VaxTrac does not report the match-
ing accuracy of children’s fingerprints, they mention that
they almost invariably end up using the mother’s finger-
prints for this purpose because matching children’s finger-
prints fails quite often 5
. Continued efforts are, therefore,
needed to advance the fingerprint technology, both sensing
technology as well as matching algorithm behind the mo-
bile vaccine registry system. In this paper, we present the
initial results of our ongoing study on using fingerprints to
recognize infants and toddlers.

2. Capturing Fingerprint Images of Children
For the aforementioned application involving identifica-
tion of infants and toddlers using their fingerprints, the first
major challenge is to capture good quality fingerprint im-
ages. This is primarily because of the following reasons:
• Semi to non-cooperative subjects: Most infants and
toddlers do not place their fingers on the fingerprint
sensor on their own. It is difficult to force them to place
their fingers properly on the sensor for more than a few
seconds. As a result, often there is insufficient time for
the fingerprint sensors to capture good quality images.
Typically, one has to hold the child’s fingerprint on the
sensor and apply some pressure.
• Oily/wet finger skin: The finger skin of newborns usu-
ally has a waxy coating on it reportedly due to a higher
percentage of sterol esters to prevent excessive wet-
ting of finger skin [14]. Besides, infants and toddlers
typically have the habit of sucking their fingers, which
affects their finger skin texture. The texture of oily/wet
finger skin directly manifests itself in the captured fin-
gerprint impression, thereby affecting the fingerprint
image quality.
• Small sized fingers: Most fingerprint sensors are de-
signed to sense adult fingers. When presented with
smaller sized infant and toddler fingers, the finger de-
tection module built into the sensors sometimes fails to
detect the presence of the finger to trigger the finger-
print capture process.
2.1. Initial Efforts
As a first step, we explored the use of two state-of-the-art
smartphone cameras (iPhone 5S and Samsung Galaxy S4
Zoom) for capturing fingerprint images of children. Despite
the use of the built-in flash, special light fixture, and an im-
age magnifier, the acquired fingerprint images were not of
sufficient quality for feature extraction and matching. Next,
we experimented with using several handheld 500 and 1000
ppi optical fingerprint sensors. Based on our experience,
desirable characteristics of a fingerprint sensor for captur-
ing fingerprints of infants and toddlers are (i) portability
because the sensor has to be brought close to the child’s fin-
ger for capturing fingerprints, (ii) compact and comfortable
sensor platen to be able to place the child’s finger properly
on the sensor platen to initiate the fingerprint capture pro-
cess, and (iii) fast capture speed because it is difficult to

print reader of (a) a five months old infant in East Lansing, United States, and (b) of

hold the child’s finger steady on the sensor platen for more
than a few seconds in most cases.
Based on the results of our initial experiments, U.are.U
4500, a 500 ppi optical fingerprint reader from Digital Per-
sona [16] provides the best quality fingerprint images of in-
fants and toddlers. Therefore, we use this optical reader for
the remainder of our data collection (see Fig. 3). Further, in
order to obtain high quality images, we (i) clean the sensor
platen periodically to prevent residue buildup from previous
fingerprint captures which appears as background noise in
the image, (ii) clean the child’s finger before placing it on
sensor platen, and (iii) apply external pressure to the child’s
finger to increase the contact area between the finger and
the sensor.
2.2. Data Collection
Fingerprint images of 90 infants and toddlers were cap-
tured using the Digital Person U.are.U 4500 optical finger-
print reader at two different locations, East Lansing, Michi-
gan in the United States and Cotonou, Benin in West Africa.
We refer to this database as the Michigan State University
Infant and Toddler Fingerprint (MSU-ITF) database.
2.2.1 East Lansing data
Initial data collection was done in East Lansing, Michigan.
A total of 1,600 fingerprint impressions (two index fingers
and two thumbs) from 20 subjects in the age range [0-4]
years were captured. Data was collected over five sessions,
about 1 week apart, and four fingerprint impressions per fin-
ger were collected in each session. Face images were also
collected in each session but they were not used for match-
ing. Instead, they were used for displaying the retrieved
subjects from the database so that the health care worker
can visually confirm the child’s identity. Fig. 4 shows the
face image and fingerprint images of one of the subjects
collected in East Lansing.
2.2.2 Benin data
We also travelled to Benin to collect operational data from
two different health clinics. The first was a rural health
clinic where fingerprint images of 20 subjects were captured
in an open air shelter in sunlight. The second was an ur-
ban clinic, where fingerprints of 50 subjects were obtained.

This data was captured in a closed room with fixed lighting.
Note that data was captured in a single session on two dif-
ferent days in the two clinics. Three impressions each of the
left index and left thumb fingers were captured resulting in
a total of 120 fingerprint impressions of 20 subjects being
captured in the rural clinic and 300 fingerprint impressions
of 50 subjects captured in the urban clinic. Fig. 5 shows the
fingerprint images of two of the subjects captured in Benin.
3. Matching Fingerprint Images of Children
Once usable fingerprint impressions are acquired, the
next task is to automatically match the captured impressions
with high accuracy. Automatic matching of the captured
fingerprints is a challenging problem because of the follow-
ing reasons:
1. Poor image quality: Despite cleaning the child’s finger
before capturing the fingerprint image, some oil/water
is at times retained in the finger skin leading to the
capture of poor quality fingerprint impressions. See
Fig. 6(a).
2. Non-linear distortion and partial impressions: Chil-
dren usually have more resilient and elastic skin which
leads to large non-linear distortion in the captured im-
pressions. Additionally, due to small finger size, the
overlap between two impressions of the same finger is
typically small. See Fig. 6(b).
3. Difficulty in feature extraction: The average inter-ridge
spacing in the MSU-ITF database is 4.9 pixels which

is about half of the 8.4 pixels of inter-ridge spacing
in FVC2002 DB1 [9]. Due to this, a commercial fin-
gerprint SDK fails to extract several genuine minutiae
from the child’s fingerprint image even though the im-
age appears to have clear ridge structure. See Fig. 6(c).
4. Variations in finger skin condition: Fig. 6(d) shows
two different impressions of the same finger of the
same subject. Although these impressions were col-
lected just one week apart, their image quality is quite
different.
3.1. Matching Strategies
To handle the aforementioned challenges, we devised the
following matching strategies to be used in conjunction with
a commercial fingerprint SDK and a state-of-the-art latent
SDK6
1. Upsample the acquired image: Fingerprint SDKs ex-
pect ridge-spacing values of about 9 pixels (a typical
value for adult fingerprints). Given that the inter-ridge
spacing for infants and toddlers is about 4.9 pixels, up-
sample the images to increase the average ridge spac-
ing before submitting it to the SDK.
2. Fuse match scores of multiple enrolled templates: En-
roll multiple templates of each finger in the gallery.
Compare each query image against all the templates
of the finger and fuse the obtained match scores.
3. Fuse match scores of two fingers: Fuse match scores
obtained from matching two fingers of each subject to
boost the matching performance.
4. Update gallery over time: Instead of simply using the
templates from the initial enrollment session, include
templates from all previous sessions in the gallery.
6We experimented with the latent SDK because several challenges in
automatically matching latent fingerprints are similar to those encountered
in matching infant and toddler fingerprints.

3.2. Matching Experiments
Matching experiments are conducted using (i) a commer-
cial fingerprint SDK and (ii) a state-of-the-art latent finger-
print SDK for both the verification and identification sce-
narios.
3.2.1 Determining the upsampling factor
Bilinear interpolation (MATLAB function: imresize) is
used for upsampling the images. Tab. 2 compares the True
Accept Rate (TAR) at a fixed False Accept Rate (FAR) of
0.1% for different scale values using the commercial finger-
print SDK on the East Lansing data. Note the increase in
TAR from 23.51% to 62.25% as the scale value is increased
from 1.0 to 1.8. Based on this observation, 1.8 is selected
as the value for upsampling the fingerprint images. In terms
of image size, a 392 × 357 fingerprint image is upsampled
to 706×643.
Fig. 7 compares the distributions of the number of minu-
tiae in the original and upsampled fingerprints in the MSU-
ITF database (with scale value 1.8) and 9,600 fingerprints
from FVC2000 [8], FVC2002 [9] and FVC2004 [10]. Note
that after upsampling, the distribution of the number of
minutiae in the MSU-ITF database comes close to that in
the FVC databases.
The average NFIQ value7
[18] for the upsampled finger-
prints in the MSU-ITF database is 1.9 compared with 3.0
in the FVC databases. The standard variation of NFIQ val-
ues for the upsampled fingerprints in the MSU-ITF database
and FVC databases is 0.9 and 1.4, respectively. Even though
NFIQ values indicate that children’s fingerprints are of good
quality, visually their quality is not good. This discrepancy
could be because NFIQ has not been designed for children
fingerprints [5].
7NFIQ value ranges from 1 to 5, with 1 indicating the highest quality
and 5 indicating the lowest quality fingerprint.
3.2.2 Fingerprint verification
Verification is the most commonly encountered scenario in
field operations. When a child who has previously been im-
munized needs to be administered subsequent vaccinations,
the health worker enters basic information into the system
such as the ID of the child. He then collects the child’s fin-
gerprints to verify his identity before administering the vac-
cine. In our experiments, the verification protocol followed
is analogous to that used in FVC.
1. Matching against each enrolled template: Matching
a query to each individual enrolled template in the
gallery from the East Lansing data results in a TAR
of 62.25% and 78.52% at a FAR of 0.1% using the
commercial fingerprint SDK and the latent fingerprint
SDK, respectively. On the Benin data at the same FAR
of 0.1%, a TAR of 30.24% is obtained using the com-
mercial fingerprint SDK whereas using the latent SDK
results in a TAR of 44.29%.
2. Fusion of match scores from multiple enrolled tem-
plates: To see the effect of the number of templates on
the verification performance of the two SDKs, TAR is
computed assuming there are two or four enrolled tem-
plates in the gallery. Average fusion scheme is found
to give the best results. At a FAR of 0.1%, the TAR af-
ter fusion improves from 62.25% to 71.01% and from
78.52% to 82.52% for the commercial fingerprint SDK
and the latent fingerprint SDK, respectively, when us-
ing two templates during the verification from the East
Lansing data. When all four enrolled templates are
used, the verification performance improves to 75.97%
and 84.84% for the two matchers on this data. On the
other hand, for the data collected in Benin, match score
fusion of two templates improves the TAR at a FAR
of 0.1% from 30.24% to 41.67% for the commercial
fingerprint SDK. For the latent SDK, this scheme im-
proves the TAR from 44.29% to 50.24%.
3. Fusion of match scores from two fingers: The best ac-
curacy (average of different combinations of two fin-
gers) was again obtained using average match score fu-
sion. Using a combination of two fingers improves the
TAR (at a FAR=0.1%) to 86.34% and 95.04% for the
commercial fingerprint SDK and the latent fingerprint
SDK, respectively, on the East Lansing data. The same
scheme improves the TAR to 57.50% and 64.27% for
the two matchers, respectively, on the Benin data. As
a comparison with adult fingerprint recognition accu-
racy, VaxTrac reports a TAR of 99.0% at 0.1% FAR or
the same matching scenario8
.
Fig. 8(a) and Fig. 8(b) show the Receiver Operating
Characteristics (ROC) curves for East Lansing and Benin
data, respectively, using different matching strategies in
conjunction with the two SDKs. Note the improvement in
TAR at different FAR thresholds.

3.2.3 Fingerprint identification
In field operations, identification mode of operation is
meaningful when the child coming for immunization
can not present any credentials. Further, identification
mode will be needed for de-duplication of the fingerprint
database. Experiments are conducted to investigate the per-
formance of the proposed matching strategies on the iden-
tification accuracy. A total of 32,768 fingerprints of 16,384
subjects (two thumbs per subject and one impression per
thumb), which were collected by VaxTrac, are used to en-
hance the gallery.
The baseline performance assumes that a single template
of a single finger per subject is present in the gallery. Match-
ing queries acquired in subsequent sessions to the first en-
rolled template directly yields a rank-1 identification accu-
racy of 46.38% and 75.46% using the commercial finger-
print SDK and the latent fingerprint SDK, respectively, on
the East Lansing data. On the Benin data, rank-1 accura-
cies of 20% and 42.85% are obtained, respectively, using
the two SDKs.
When multiple templates of a finger are enrolled, we
match the query against all the enrolled templates. This is
followed by fusing the match scores obtained from match-
ing the probe against multiple templates using the max fu-
sion strategy. For the East Lansing data, the rank-1 identi-
fication accuracy improves to 64.16% and 85.80%, respec-
tively, for the two SDKs when using four templates. Us-
ing the two enrolled templates in the gallery improves the
rank-1 identification accuracy to 29.29% and 55.71% for
the commercial fingerprint SDK and the latent fingerprint
SDK, respectively, on the Benin data.
A max fusion of the match scores obtained from match-
ing two different fingers with multiple templates in the
gallery further improves the identification accuracy. With
two finger fusion strategy (average of different combina-
tions of two fingers) in addition to multiple enrolled tem-
plates, the rank-1 identification rate improves to 73.98%
for the commercial fingerprint SDK on the East Lansing
data. For the latent fingerprint SDK, the rank-1 accuracy
improves to 95.52% using the same strategy on this data.
On the data collected in Benin, the commercial fingerprint
SDK obtains a rank-1 identification rate of 40.00% whereas

the latent fingerprint SDK’s rank-1 identification accuracy
improves to 67.14% when fusing the match scores obtained
from two fingers. Note that the fusion of thumb and the
index finger showed the best performance improvement.
Updating the gallery by using templates from multiple
sessions further improves the matching performance. The
rank-1 identification accuracy improves from 73.98% to
83.77% for the commercial fingerprint SDK on the East
Lansing data when using the updated gallery in conjunc-
tion with thumb and index finger fusion. The rank-1 accu-
racy of the latent fingerprint SDK improves from 95.52% to
98.97% using this strategy on the same data. Note that this
scheme could not be evaluated on the Benin data because
fingerprint images were acquired in a single session at the
two health clinics.
Fig. 9(a) and Fig. 9(b) show the Cumulative Match
Characteristics (CMC) curves for East Lansing and Benin
data, respectively, using different matching strategies in
conjunction with the two SDKs. Note the improvement in
identification accuracies of the two SDKs. Tab. 3 and Tab.
4 summarize the identification accuracies for different sce-
narios on the two databases.
For the vaccination tracking application, we propose to
use fingerprints to retrieve the top N subjects from the
database and then display the face images of the retrieved
candidates. This allows the health worker to verify the
true mate of the query. This way, if we display the top-10
retrieved candidates (N =10), identification accuracy can
potentially be improved to 99.39% and 71.43% (based on
using the latent fingerprint SDK on the East Lansing and
Benin data, respectively). Fig. 10 gives an example for
N = 9, where the face image (denoted using a red bound-
ary) is the true mate for the given fingerprint query.
There are two main reasons for the failure to retrieve the
true mate at rank-N: (i) query impressions or templates are
of very low quality (see Fig. 11 (a)); (ii) small overlap and
large distortion between the query and the templates in the
gallery (see Fig. 11 (b)). With augmented gallery, we are
able to retrieve the true mate for the query in Fig. 11 (b), but
the query in Fig. 11 (a) does not lead to successful mate.
Note that, in general, the identification accuracies ob-
tained by the two fingerprint SDKs used in our experiments

are lower on the Benin data compared to the East Lansing
data. In our opinion, this is because of the following rea-
sons:
• Acquisition environment: High temperature and hu-
midity in Benin result in non-ideal operating condi-
tions for fingerprint sensors. On the other hand, East
Lansing has comparatively lower temperature and is
significantly less humid, As a result, the environment
is more suited for fingerprint capture in East Lansing.
Besides, the East Lansing data was captured in chil-
dren’s homes as opposed to health clinics in Benin.
• Difference in age of subjects: Most subjects in the East
Lansing data are over 6 months old whereas in Benin,
most subjects are younger than 6 months. Younger
children typically have the habit of sucking their fin-
gers affecting the finger skin texture and as a result,
adversely affecting the fingerprint image quality.
4. Conclusions and Future Work
Vaccine-preventable diseases continue to take a heavy
toll on children in geographical regions and countries with-
out a high immunization coverage. For improving the im-
munization coverage, an effective immunization program
needs to keep track of the vaccination schedule of children.
In this paper, we have investigated the viability of using fin-
gerprints for identifying toddlers and infants (age range of
0-4 years) for this application. A total of 1,600 fingerprint
images of four fingers each from 20 subjects were collected
over a period of 30 days in East Lansing, United States and
420 fingerprints of two fingers each from 70 subjects were
collected in two different health clinics in Benin. The cap-
tured images of infants and toddlers were upsampled to fa-
cilitate reliable feature extraction using commercial SDKs.
Fusion of multiple templates and multiple fingers are in-
vestigated as potential matching strategies, to improve the
matching performance of a commercial fingerprint SDK
and a state-of-the-art latent fingerprint SDK. Our experi-
mental results show that fusing the matching results of the
thumb and index fingers (using two/four templates per fin-
ger) when matching against an extended gallery of 32,768
8. (a) (b)

infant fingerprints significantly improves the matching per-
formance. Updating the gallery by including templates cap-
tured in all previous sessions further improves the rank-
1 (rank-10) identification rate of a commercial fingerprint
SDK to 83.8% (89.6%) and 40.00% (48.57%) for the East
Lansing and Benin data, respectively. The rank-1 (rank-
10) accuracy of state-of-the-art latent matcher improves to
98.97% (99.39%) and 67.14% (71.43%) using these strate-
gies on the two datasets, respectively.
In future, we plan to explore alternative capture tech-
nologies for capturing fingerprints of infants and toddlers.
We are also investigating ways to further improve the
matching performance by (i) using an adaptive scale pa-
rameter depending on child’s age because there is a large
variation of fingerprint size in the age range of [0,4] and (ii)
preprocessing the fingerprint images to enhance the ridge
structure before submitting it to the fingerprint SDKs.
