Network security is enhanced through biometrics authentication which uses unique physical traits to verify user identity. Biometrics is more secure than passwords since traits cannot be forgotten, stolen, or easily copied. The document discusses common biometric traits like fingerprints, iris scans, and voice recognition. It explains how biometric systems work by enrolling traits during initial use then comparing submitted traits to stored information for authentication. Biometrics provides stronger security for networks and systems by using the human body as a verification method.
1. The document discusses biometrics as a means of identity verification and authentication using human physiological and behavioral characteristics like fingerprints, iris patterns, voice, etc.
2. Biometric systems work by collecting, transmitting, processing and storing biometric data to make decisions about identity verification. They are being used in applications like banking, border control, and device access.
3. While biometrics provide high security and convenience by eliminating reliance on tokens and passwords, systems need to balance accuracy rates and intrusiveness on user privacy. India is also witnessing growth in biometric solution developers and applications.

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.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

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.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
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%.

3. Imagine how convenient it would be to activate the security alarm at your home
with the touch of a finger, or to enter your home by just placing your hand on the
door handle. How would you like to walk up to a nearby ATM which will scan your
iris so you can withdraw money without ever inserting a card or entering a PIN.
You will basically be able to gain access to everything you are authorized to, by
presenting yourself as your identity. This scenario might not be as far off as we
might expect. In the near future, we may no longer use passwords and PIN
numbers to authenticate ourselves. These methods have proven to be insecure
and unsafe time and time again. Technology has introduced a much smarter
solution to us: Biometrics. Biometrics, the use of a person’s unique biological
characteristics (such as face, voice, or fingerprints) for personal identification has
gained a lot of popularity in recent past!!
4. The advantages of biometrics are becoming more apparent with the increasing
use of computers in our daily life. As cyber crime increases, the need for security
against identity theft becomes more and more apparent. Add to this the ever-
increasing threat to personal, corporate and government assets, the need for
better forms of security is obvious. Biometric authentication will help in enhancing
the security infrastructure against some of these threats. After all, physical
characteristics are not something that can be lost, forgotten or passed from one
person to another. They are extremely hard to forge and a would-be criminal
would think twice before committing a crime involving biometrics.

6. The Sensing Element
The sensing element, or the input interface element, is the hardware core of a
biometrics system and converts human biological data into digital form. This could
be a complementary metal oxide semiconductor (CMOS) imager or a charge
coupled device (CCD) in the case of face recognition, handprint recognition or
iris/retinal recognition systems; a CMOS or optical sensor in the case of fingerprint
systems; or a microphone in the case of voice recognition systems. These
sensors capture the biometric information and convert it into a digital form that can
be processed by the next stage - the processing element.
7. The Processing Element
The processing element is generally a microprocessor, digital signal processor or
computer that processes the data captured from the sensors. The processing of
the biometric image generally involves image enhancement, normalization,
template extraction, and matching/comparison of the biometric template during
enrollment and authentication of the users. A programmable processor like the
DSP from TI can address all the processing needs of a biometric system while
providing the most viable path to standards and feature upgrades. A DSP allows
the product to be small and portable while maintaining power-efficient
performance — all at a low overall system cost.
8. The Processing Element(contd.)
The DSP architecture is built to support complex mathematical algorithms that
involve a significant amount of multiplication and addition. The DSP executes the
multiply/add feature in a single cycle (compared to multiple cycles for RISC
processors) with the help of the multiply/accumulate (MAC) hardware inside the
arithmetic logic unit (ALU). In addition, the Harvard architecture of the DSP
(multiple busses) allows instruction and operand fetches in the same cycle for
increased speed of operation.Developers of biometrics systems can take
advantage of this architecture to enhance the resolution of the captured image
with the use of two-dimensional fast fourier transforms (FFT) and finite IR filters.
Because the accuracy of a system is as much dependent on the input image as it
is on the processing algorithm, this helps in improving the overall accuracy and
error rate of the biometrics system - a key performance metric.
9. The Processing Element(contd.)
With the high performance capabilities of the DSP, the total recognition time of the
system can be reduced without an increase in power consumption generally
associated with faster processors. This low-power consumption in TI DSPs is
achieved with hardware enhancements and leading-edge process technology,
providing customers with a powerful, yet low-overhead processor for multiple
biometric applications.
10. The Storage Element
The function of the storage element is to store the enrolled template that
is recalled to perform a match at the time of authentication. For most
identification solutions (1:N), the storage element would be random
access memory (RAM) or flash EPROM or some other form of memory
IC, and in some other cases it could be a data server. In the case of
verification (1:1), a removable storage element like a contact or
contactless smart card can be used.
11. Interface Element
Finally, there is the output interface element, which will communicate the decision
of the biometric system to the interfaced asset to enable access to the
user.Several ’54x devices implement a variety of types of flexible serial port
interfaces. These serial port interfaces provide full duplex, bidirectional,
communication with serial devices such as codecs, serial analog to digital (A/D)
converters, and other serial systems. Here also we are using the same interface
method!!
16. Pulse Oximeters in clinics have a finger clip type probe that has an LED on one
side and a photodetector on the other side. The light emitted from one side of the
finger travels through tissue, venous blood and arterial blood and is collected in
the detector. Most of the light is absorbed or scattered before it reaches the photo
detector in the other side of the finger. The flow of blood is heartbeat induced, or
pulsatile in nature so the transmitted light changes with time. Red and infrared
lights are used for pulse oximetry to estimate the true hemoglobin oxygen
saturation of arterial blood. Oxyhemoglobin (HbO2) absorbs visible and infrared
(IR) light differently than deoxyhemoglobin (Hb), and appears bright red as
opposed to the darker brown Hb.The optical system for monitoring consists of
LEDs that shine the light and a photodiode that receives the light. There are two
types of optical arrangements – Transmissive and Reflective.
17. In the transmissive case, the photodiode and the LED are placed on opposite sides of the
human body part (most commonly the finger), with the photodiode collecting the residual
light after absorption from the various components of the body part. In the reflective case,
the photodiode and the LED are on the same side and the photodiode collects the light
reflected from various depths underneath the skin. With the conventional finger clip type
probes commonly seen in a clinic, one could simply imagine that the emitted light from the
LED goes straight through the tissue, interacts with blood cells somehow and continues to
travel in the same direction until it reaches the photodiode, or photo detector (PD). This is
not the case. Photons in the light scatter in every direction when it hits an object, for
example, blood cells. LED and PD separation in the finger clip probe is around 10 mm.
However, most of the photons travel 20 cm to 10 cm before reaching the PD. Some travel as
long as 200 mm. The photons could be described as walking randomly. This is why glow is
seen in the skin of the finger tip in following figure. If the light traveled in the straight path,
that is the shortest one, how could the surrounding skin of the finger glow so bright? Since
we have gotten out of the old belief that the emitter and detector have to face each other, we
can try placing them in easier directions like side-by-side or even at 90 degrees.
18.
19. AFE4403
Ultra-Small, Integrated Analog Front-End for Heart Rate
Monitors and Low-Cost Pulse Oximeters
The AFE4403 is a fully-integrated analog front-end (AFE) ideally suited for pulse
oximeter applications. The device consists of a low-noise receiver channel with an
integrated analog-to-digital converter (ADC), an LED transmit section, and
diagnostics for sensor and LED fault detection. The device is a very configurable
timing controller. This flexibility enables the user to have complete control of the
device timing characteristics. To ease clocking requirements and provide a low-
jitter clock to the AFE4403, an oscillator is also integrated that functions from an
external crystal. The device communicates to an external microcontroller or host
processor using an SPI™ interface.
22. Conclusion
Biometrics is a truly emerging market with great potential for success. Its roots may be in science fiction,
but it is part of today’s science and technology fact. In the near future, we will come to rely on biometric
technology to protect our property, assets, and the people we love. We will see this technology become a
secure and trusted form of authentication with uses varying from controlling access to personal
information devices, to securing buildings and enabling eCommerce. DSP plays an important role in the
development and adoption of biometric systems. It helps improve the performance and accuracy of these
systems with its high performance architecture. The differentiation will be in enabling multiple new
applications with smart biometric solutions powered by a DSP. All of this can be achieved at a low overall
system cost as a result of design reuse and faster time-to-market. This, in turn will help create a growth
market for affordable intelligent security systems. In conclusion, using DSP as the embedded processor of
choice for enabling smart biometric systems can provide the following advantages:
• Fast, accurate, secure and trusted authentication
• Enable new applications with one scalable design
• Reduce overall cost of development
