Distributed Digital Artifacts on the Semantic WebEditor IJCATR
Distributed digital artifacts incorporate cryptographic hash values to URI called trusty URIs in a distributed environment
building good in quality, verifiable and unchangeable web resources to prevent the rising man in the middle attack. The greatest
challenge of a centralized system is that it gives users no possibility to check whether data have been modified and the communication
is limited to a single server. As a solution for this, is the distributed digital artifact system, where resources are distributed among
different domains to enable inter-domain communication. Due to the emerging developments in web, attacks have increased rapidly,
among which man in the middle attack (MIMA) is a serious issue, where user security is at its threat. This work tries to prevent MIMA
to an extent, by providing self reference and trusty URIs even when presented in a distributed environment. Any manipulation to the
data is efficiently identified and any further access to that data is blocked by informing user that the uniform location has been
changed. System uses self-reference to contain trusty URI for each resource, lineage algorithm for generating seed and SHA-512 hash
generation algorithm to ensure security. It is implemented on the semantic web, which is an extension to the world wide web, using
RDF (Resource Description Framework) to identify the resource. Hence the framework was developed to overcome existing
challenges by making the digital artifacts on the semantic web distributed to enable communication between different domains across
the network securely and thereby preventing MIMA.
Exploring and comparing various machine and deep learning technique algorithm...CSITiaesprime
Domain generation algorithm (DGA) is used as the main source of script in different groups of malwares, which generates the domain names of points and will further be used for command-and-control servers. The security measures usually identify the malware but the domain name algorithms will be updating themselves in order to avoid the less efficient older security detection methods. The reason being the older detection methods does not use either the machine learning or deep learning algorithms to detect the DGAs. Thus, the impact of incorporating the machine learning and deep learning techniques to detect the DGA is well discussed. As a result, they can create a huge number of domains to avoid debar and henceforth, block the hackers and zombie systems with the older methods itself. The main purpose of this research work is to compare and analyse by implementing various machine learning algorithms that suits the respective dataset yielding better results. In this research paper, the obtained dataset is pre-processed and the respective data is processed by different machine learning algorithms such as random forest (RF), support vector machine (SVM), Naive Bayes classifier, H20 AutoML, convolutional neural network (CNN), long short-term memory neural network (LSTM) for the classification. It is observed and understood that the LSTM provides a better classification efficiency of 98% and the H20 AutoML method giving the least efficiency of 75%.
This document summarizes a research paper that proposes using machine learning models to detect phishing websites. It begins with an abstract that introduces the growing problem of phishing attacks and how machine learning can help address it. The document then provides more detail on the proposed methodology, which includes collecting a dataset of legitimate and phishing URLs, extracting features from the URLs, and training/comparing several machine learning models (decision trees, random forests, XGBoost, etc.). It finds that the XGBoost model performs best at classifying URLs as legitimate or phishing. The summary concludes by noting this approach could help create effective phishing detection tools, while acknowledging challenges like accounting for evolving attack types and adversarial examples.
Data Security In Relational Database Management SystemCSCJournals
Proving ownerships rights on outsourced relational database is a crucial issue in today\'s internet based application environments and in many content distribution applications. Here mechanism is proposed for proof of ownership based on the secure embedding of a robust imperceptible watermark in relational data. Watermarking of relational databases as a constrained optimization problem and discus efficient techniques to solve the optimization problem and to handle the constraints. This watermarking technique is resilient to watermark synchronization errors because it uses a partioning approach that does not require marker tuple. This approach overcomes a major weakness in previously proposed watermarking techniques. Watermark decoding is based on a threshold-based technique characterized by an optimal threshold that minimizes the probability of decoding errors. An implemented a proof of concept implementation of our watermarking technique and showed by experimental results that our technique is resilient to tuple deletion, alteration and insertion attacks.
The document proposes new distributed deduplication systems with higher reliability for secure cloud storage. Data chunks are distributed across multiple cloud servers using a deterministic secret sharing scheme. This improves reliability over traditional deduplication systems that store only one copy of each file. The systems aim to achieve security requirements of data confidentiality and consistency while limiting overhead.
This document proposes new distributed deduplication systems with higher reliability for secure cloud storage. The key points are:
1. Existing deduplication systems improve storage efficiency but reduce reliability as files are only stored once in the cloud.
2. The proposed systems distribute file chunks across multiple cloud servers using secret sharing to improve reliability.
3. Security mechanisms like confidentiality and tag consistency are achieved through deterministic secret sharing rather than encryption.

Creation of smart spaces and scaling of devices to achieve miniaturization in pervasive computing environments has put forth a question on the degree of security of such devices. Security being a unique challenge in such environments, solution demands scalability, access control, heterogeneity, trust. Most of the existing cryptographic solutions widely in use rely on the hardness of factorization and number theory
problems. With the increase in cryptanalytic attacks these schemes will soon become insecure. We need an alternate security mechanism which is as hard as the existing number theoretic approaches. In this work, we discuss the aspects of Lattice based cryptography as a new dimension of providing security whose strength lies in the hardness of lattice problems. We discuss about a cryptosystem whose security relies on high lattice dimension.

This document summarizes a paper that presents a novel method for passive resource discovery in cluster grid environments. The method monitors network packet frequency from nodes' network interface cards to identify nodes with available CPU cycles (<70% utilization) by detecting latency signatures from frequent context switching. Experiments on a 50-node testbed showed the method can consistently and accurately discover available resources by analyzing existing network traffic, including traffic passed through a switch. The paper also proposes algorithms for distributed two-level resource discovery, replication and utilization to optimize resource allocation and access costs in distributed computing environments.

ACTOR CRITIC APPROACH BASED ANOMALY DETECTION FOR EDGE COMPUTING ENVIRONMENTSIJCNCJournal
The pivotal role of data security in mobile edge-computing environments forms the foundation for the
proposed work. Anomalies and outliers in the sensory data due to network attacks will be a prominent
concern in real time. Sensor samples will be considered from a set of sensors at a particular time instant as
far as the confidence level on the decision remains on par with the desired value. A “true” on the
hypothesis test eventually means that the sensor has shown signs of anomaly or abnormality and samples
have to be immediately ceased from being retrieved from the sensor. A deep learning Actor-Criticbased
Reinforcement algorithm proposed will be able to detect anomalies in the form of binary indicators and
hence decide when to withdraw from receiving further samples from specific sensors. The posterior trust
value influences the value of the confidence interval and hence the probability of anomaly detection. The
paper exercises a single-tailed normal function to determine the range of the posterior trust metric. The
decision taken by the prediction model will be able to detect anomalies with a good percentage of anomaly
detection accuracy.

IRJET- Efficient Privacy-Preserving using Novel Based Secure Protocol in SVMIRJET Journal
This document presents a novel framework for improving privacy and efficiency in support vector machine (SVM) classification. The framework uses a lightweight multiparty random masking protocol to encrypt user data before it is sent to a server for SVM classification. The classification results are then stored in the cloud. A polynomial aggregation protocol is also used to prevent data leakage while maintaining privacy. The proposed approach is evaluated using two real datasets and is shown to achieve higher accuracy and efficiency compared to conventional methods, while ensuring user data privacy.
Charm a cost efficient multi cloud data hosting scheme with high availabilityPvrtechnologies Nellore
The document proposes a data hosting scheme called CHARM that selects multiple cloud storage providers and redundancy strategies to store data with minimized costs and high availability. CHARM intelligently distributes data using replication or erasure coding based on file size and access patterns. It also triggers transitions of storage modes and data redistribution in response to changing access patterns and cloud pricing. Evaluation shows CHARM saves around 20% of costs compared to other schemes and adapts well to data and price changes.
Efficient Association Rule Mining in Heterogeneous Data BaseIJTET Journal
This document summarizes an algorithm for efficiently mining association rules from heterogeneous databases. The algorithm distributes the database across multiple sites while ensuring privacy. Each site locally mines frequent itemsets using an algorithm like Apriori. The sites then securely combine candidate itemsets and check rule confidence to find globally frequent rules meeting minimum support and confidence thresholds. The algorithm uses commutative encryption and a map-reduce model to parallelize the distributed mining efficiently while limiting data disclosure between sites.
Efficient Similarity Search over Encrypted DataIRJET Journal
This document summarizes a research paper that proposes an efficient method for similarity search over encrypted data stored in the cloud. The method uses Locality Sensitive Hashing (LSH) to index the encrypted data and generate "trapdoors" or encodings of search queries. When a user submits a query, the trapdoor is generated and similarity search is performed by finding the similarity between the query trapdoor and the encrypted data indexes stored in the cloud, without decrypting the actual data. The paper outlines the data uploading and query processing steps, which include preprocessing, encryption, trapdoor generation using LSH-based bucketing of n-grams from the query terms, and using Bloom filters for efficient similarity matching during search.
IRJET- Privacy Preserving Cloud Storage based on a Three Layer Security M...IRJET Journal
This document proposes a three-layer security model for privacy-preserving cloud storage. The model uses encryption techniques like AES and Triple DES to encrypt user data before storing it in the cloud. The encrypted data is then divided into blocks that are distributed across different cloud, fog, and local storage locations. This prevents data leakage even if some blocks are lost or accessed. Computational intelligence paradigms help optimize the distribution of data blocks for efficiency and security. The model aims to provide stronger privacy protection compared to traditional cloud storage security methods.

IRJET- Efficient Privacy-Preserving using Novel Based Secure Protocol in SVMIRJET Journal
This document presents a novel framework for improving privacy and efficiency in support vector machine (SVM) classification. The framework uses a lightweight multiparty random masking protocol to encrypt user data before it is sent to a server for SVM classification. The classification results are then stored in the cloud. A polynomial aggregation protocol is also used to prevent data leakage while maintaining privacy. The proposed approach is evaluated using two real datasets and is shown to achieve higher accuracy and efficiency compared to conventional methods, while ensuring user data privacy.
Charm a cost efficient multi cloud data hosting scheme with high availabilityPvrtechnologies Nellore
The document proposes a data hosting scheme called CHARM that selects multiple cloud storage providers and redundancy strategies to store data with minimized costs and high availability. CHARM intelligently distributes data using replication or erasure coding based on file size and access patterns. It also triggers transitions of storage modes and data redistribution in response to changing access patterns and cloud pricing. Evaluation shows CHARM saves around 20% of costs compared to other schemes and adapts well to data and price changes.
Efficient Association Rule Mining in Heterogeneous Data BaseIJTET Journal
This document summarizes an algorithm for efficiently mining association rules from heterogeneous databases. The algorithm distributes the database across multiple sites while ensuring privacy. Each site locally mines frequent itemsets using an algorithm like Apriori. The sites then securely combine candidate itemsets and check rule confidence to find globally frequent rules meeting minimum support and confidence thresholds. The algorithm uses commutative encryption and a map-reduce model to parallelize the distributed mining efficiently while limiting data disclosure between sites.
Efficient Similarity Search over Encrypted DataIRJET Journal
This document summarizes a research paper that proposes an efficient method for similarity search over encrypted data stored in the cloud. The method uses Locality Sensitive Hashing (LSH) to index the encrypted data and generate "trapdoors" or encodings of search queries. When a user submits a query, the trapdoor is generated and similarity search is performed by finding the similarity between the query trapdoor and the encrypted data indexes stored in the cloud, without decrypting the actual data. The paper outlines the data uploading and query processing steps, which include preprocessing, encryption, trapdoor generation using LSH-based bucketing of n-grams from the query terms, and using Bloom filters for efficient similarity matching during search.
IRJET- Privacy Preserving Cloud Storage based on a Three Layer Security M...IRJET Journal
This document proposes a three-layer security model for privacy-preserving cloud storage. The model uses encryption techniques like AES and Triple DES to encrypt user data before storing it in the cloud. The encrypted data is then divided into blocks that are distributed across different cloud, fog, and local storage locations. This prevents data leakage even if some blocks are lost or accessed. Computational intelligence paradigms help optimize the distribution of data blocks for efficiency and security. The model aims to provide stronger privacy protection compared to traditional cloud storage security methods.

This document discusses the pathogenesis and diagnosis of schizophrenia from the perspective of mitochondrial dysfunction and nonlinear dynamics analysis. It summarizes that:
1) Schizophrenia is thought to result from an interplay between genetic and environmental factors that disrupt brain development, and recent research implicates mitochondrial dysfunction caused by disruption of multiple genes.
2) Studies using nonlinear dynamics analysis of EEG signals and other data have found reduced complexity and more linear/regular rhythms in schizophrenia patients compared to controls, indicating lower chaotic dynamics.
3) Quantum biophysical semeiotics clinical evaluation techniques can detect an inherited real risk of schizophrenia even in asymptomatic individuals by examining microvascular function and complexity of oscillations. This allows for early pre-clinical diagnosis

Comprehensive Guide to Balcony Waterproofing Repairs
Addressing Leaking Balconies, Roofs, and Rooftop Terraces
Leaking balconies, roofs, and rooftop terraces can cause catastrophic damage to structures below. Water leaks may cause not only aesthetic and superficial damage but can also compromise the structural integrity of the building envelope. If a failed waterproofing membrane is the cause, re-grouting or surface sealing is merely a temporary fix. Such band-aid methods will eventually fail, causing cracks in tiles, grout, and membranes as the balcony moves.
In many cases, failed membranes require a complete strip-off, structural repairs if needed, reinstallation of waterproofing, and a new finish surface. Key considerations in this process include the strength of the subfloor and screed, presence of substrate dips and hollows, correct balcony slope and fall, window and door frame installation, door threshold sealing, adequate drainage, and the potential for underlying pipe leaks. Existing tiling and expansion joints should also be assessed to determine their role in the balcony failure.
Waterproofing Preparation
Proper preparation is critical for any waterproofing membrane installation. The substrate must be clean, free of dirt and other contaminants. This involves vacuum cleaning and/or diamond grinding to ensure a smooth, dry, and debris-free surface. In some cases, washing the substrate may be necessary.
Waterproofing Detailing
Before installing a waterproofing system, construction features that interrupt the membrane layer must be adequately protected and sealed. This includes:
Perimeter Upturns: Attachment points for railings and balustrades, joints between horizontal and vertical surfaces, and structural and expansion joints. Sealant should be applied 15mm wide to all junctions, reinforced with polyester or fiberglass mat to a DFT of 1.2mm, 100mm above finished floor height, or 25mm above the water line. The membrane system should be installed 200mm onto balcony floor areas.
Door/Window Step Downs: Similar to perimeter upturns, apply sealant 15mm wide to all junctions, reinforced with fiberglass mat to a DFT of 1.2mm, ensuring the membrane system is installed 200mm onto balcony areas.
Drains & Floor Waste Details: All floor wastes should have a recessed leak control flange installed, primed with appropriate primer, and the membrane system installed as per specifications.
Waterproofing Installation: Australian Standards
The installation of a Class 2/3 waterproof membrane system to external concrete must comply with AS 4654.2. Key considerations for installation include:
Installation Conditions: Avoid installation in extreme temperatures (below 10°C or above 35°C) to prevent accelerated or decelerated cure times.
Type of Membrane: Use a flexible waterproofing membrane capable of withstanding normal cyclic fluctuations and ponding water.

Advancing Waterproofing Expertise with AIW
Waterproofing Melbourne and beyond, the Australian Institute of Waterproofing (AIW) is proud to introduce an innovative commercial waterproofing course. Developed in collaboration with the Master Builders Association Vic, this course, led by Andrew Golle, is tailored for project managers overseeing balcony waterproofing, roof waterproofing, and concrete repair. Paul Evans emphasizes the critical nature of these roles in preventing costly post-construction issues. Private sessions for building supervisors are now available, addressing common mistakes due to poor applications and cost-cutting measures.
The course covers essential topics, including product selection, surface preparation, and the importance of basement waterproofing. Paul Evans highlights the recurring problems seen in the industry, where inadequate training and oversight lead to significant issues, from retaining wall waterproofing to lift pit waterproofing.
In response to these challenges, the AIW is developing a "Below Ground Waterproofing Standard" specific to Australia, inspired by UK standards. Paul Evans calls for industry-wide collaboration to ensure the standard encompasses diverse methods and materials, ultimately enhancing the quality and longevity of waterproofing work.
By equipping supervisors and builders with the right knowledge, AIW aims to improve the overall standard of waterproofing practices, reducing the risk of failures and the subsequent mental and financial stress on homeowners. This proactive approach is crucial for the sustainability and reliability of waterproofing in construction projects across Australia.

A Comparison Study of Random Forest and Logistic
Regression for Password Strength Classification
To what extent is Random Forest (RF) favourable over Logistic Regression (LR)
based on performance in password strength classification?
By: Ananya Jain
Abstract
Context: Passwords have become the universal method of authentication due to their
simplicity and compatibility across a wide range of systems. However, due to their
wide-spreadness, they have become vulnerable to external attacks like password cracking.
Users are infamously poor at maintaining entropy in their passwords due to their tendency of
including dictionary words, names, places, dates, keyboard patterns and so on in passwords,
making them predictable. Password strength classifiers developed using machine learning
algorithms like Random Forest (RF) and Logistic Regression (LR) can efficiently prevent
attacks by coercing users to create strong passwords.
Subjects and Methods: In this study, I trained two machine learning models to detect the
strength of different passwords. The two models use Random Forest and Logistic Regression
respectively to classify passwords strengths as 0,1 or 2 with 0 being weak and 2 being
strongest. I tested the model on 669,643 independent passwords retrieved from Kaggle and
evaluated the models’ classification against password standards.
Results: Random Forest has higher prediction accuracy whereas Logistic Regression has
better time performance
3. Keywords: password strength modelling, Random Forest, Logistic Regression, machine
learning
1. Introduction
Password Strength Classifiers are algorithms used to assess the strength or effectiveness of
passwords. They are designed to analyse characteristics of a password like length, use of
diverse character classes, and complexity to compute a score indicating the password’s level
of security. Higher score means the password is more effective against external attacks.
The usefulness of password classifiers however lies in their ability to give real-time feedback
to users regarding the strength of the password they are creating. Through this, users are
forced to use more secure passwords for their accounts1
.
Password strength classification is used across a variety of websites during the user
registration process for enforcing strong passwords. These are also extended by password
managers like LastPass2
who use it for assessing the safety of users’ saved passwords and for
suggesting strong passwords. Additionally, password classifiers are paving their way into
education with services like Password Monster that are being used to teach users about good
password habits3
.
An approach to creating these algorithms is through machine learning. Random Forest (RF)
and Logistic Regression (LR) are two machine learning models to classify password strength.
However, it is unclear which model is better based on prediction accuracy and prediction
time. Additionally, variation in performance between RF and RS could differ for different
application and development budgets.

Therefore, this paper seeks to investigate whether Random Forest (RF) outperforms
Logistic Regression (LR) for password strength classification, as measured by prediction
accuracy and prediction time. This research could help developers make comprehensive
decisions on whether a Random Forest or Logistic Regression should be used, which
eliminates investing unnecessary time, computer resources and labour attempting to fit data
into an ‘unsuitable’ machine learning algorithm when a better alternative exists, especially
considering machine learning models can require weeks to develop for real world accuracy.4
2. Theoretical Background
2.1 Password Strength
Password Strength is the measure of a password’s resistance against brute-force attacks and
password cracking. The strength lies in the following characteristics of the password:
complexity, length and unpredictability5
. To fulfil these criteria, the following guidelines must
be adhered:
- Password length to be at least 12 characters, preferably more
- Use of both uppercase and lowercase characters
- Avoid dictionary words, keyboard patterns, repetitive characters, and letter sequences
- Avoid using names, addresses, phone numbers, or other personal details
- Avoid common passwords like (password, qwerty, 123456)
- Use a random combination of letters, numbers and symbols6
For this paper, combinations of the above guidelines are grouped together to form the basis of
weak, medium and strong passwords which are numerically represented as 0, 1 and 2
respectively. The nature of each password strength level is described in the table below
Figure 1: Password Strength Classification
5. Password Strength Reason
(i) patty94 Weak (0) + Combination of letters and numbers
− Less than 12 characters
− Use of name
− Only lowercase letters
− No symbols
(ii) alimagik1 Medium (1) + No identifiable dictionary words
+ Combination of letters and numbers
− No uppercase letters
− No symbols
− Less than 12 characters
(iii) TyWM72UNEex8Q8Y! Strong (2) + More than 12 characters
+ Mix of uppercase and lowercase letters
+ Combination of letters and numbers
+ Random arrangement, no identifiable sequences
+ Symbol present
2.2 Drawbacks of Decision Tree
Although decision trees can be used for password strength classification, they may be deemed
unsuitable due to the problem of overfitting, especially when dealing with high-dimensional
data like passwords.
Figure 2: Decision Tree7
A decision tree is generated by recursive splitting of data, based on the most informative
feature, into decision nodes that are used to make decisions and leaf nodes that determine the
result.8
Overfitting occurs during this recursive process when the decision tree catches
random fluctuations or noise in the data instead of learning the underlying patterns. This
overfitting issue can be solved by Random Forest.9
For this reason, Random Forest has been

2.3 Drawbacks of Linear Regression
Linear regression cannot be used because it lacks suitability for password strength
classification due its inherent nature of predicting only numerical continuous outcomes,
whereas password classification involves categorisation into discrete classes.

Figure 3: Linear Regression10
In Linear Regression, a linear regression is assumed between the inputted feature and output.
In the case of password classification, a complex relationship exists between password
feature and password strength, therefore, the linear regression model will not accurately
7. capture the relationship11
. For this reason, Logistic Regression is used instead, which is better
suited to such classification problems.
2.4 Random Forest Algorithm
Random Forest is a supervised machine learning algorithm built on the concept of ensemble
learning, where multiple classifiers are combined to solve complex problems12
. Like the name
suggests, a random forest is a collection of multiple decision trees that are trained on various
data subsets through a technique known as bootstrapping. Multiple decision trees enhance

accuracy as instead of relying on a single decision tree, the algorithm takes the prediction
from each tree. In order to compute a result, a majority voting is done with each tree’s
prediction13
.
Since each tree is generated independently with different data and attributes, Random Forest
allows parallelisation, meaning the CPU can fully be used to create random forests.
Moreover, as majority voting is carried out, the model’s performance is not heavily affected
by minor changes in the dataset, improving stability of the model. The majority vote also has
the added advantage of resistance to overfitting.

During Training: Random data points are selected without replacement from the training data
to build individual decision trees. During construction of the trees, at each node the algorithm
partitions the data until a certain stopping criteria is met.
During Testing: For the same password instance from the training set, every tree individually
predicts based on its individual criteria, as seen in the image above, different trees give
different predictions. These predictions are then considered as votes and the class with the
most votes is then declared as the final predicted class.
2.5 Logistic Regression Algorithm
Logistic Regression is a supervised learning classification algorithm capable of predicting a
target variable’s probability based on dependent variables. The main purpose of the model is
9. −𝑥
to find the best fitting model to describe a relationship between an independent variable and a
dependent variable14
. A logistic function is used to model the dependent variable, hence, the
name logistic regression. This logistic function is represented the sigmoid function as below:
𝑆(𝑥) = 1
1 + 𝑒
Logistic Regression calculates its output using this equation to return a probability value
(between 0 and 1) determining its classification15
. Although logistic regression is traditionally
used for binary classification, it can be extended further to classify three or more classes,
known as Multinomial Binary Classification16
, which is used in this case.

As Logistic Regression carries out relatively simple calculations in comparison to other
models, it is extremely quick at classifying unknown records. Moreover, as it draws linear
boundaries between the different classes, the risk of overfitting is minimised.

During Training: Three different binary classifiers are trained for each output class (Weak,
Medium and Strong). All three models are trained on the same test data, however the labels
of positive or negative differ in each case. Through this, a threshold is calculated of ‘Weak’
or ‘Not Weak’, ‘Medium’ or ‘Not Medium’ and ‘Strong’ or ‘Not Strong’, as seen in the
image above.
During Testing: The password is passed through all three models and each model gives out an
output score indicating the probability of the password belonging to that class. The password
is then predicted to belong to the class with the highest probability.
3. Methodology
3.1 Dataset and Pre-processing
The two models were developed with Google Collaboratory18
using Python. To train and test
the models, the Password Strength Classification dataset from Kaggle was used19
. The dataset
contains a total of 669643 passwords. The CSV file contains the password along with a
strength measure equal to 0, 1 or 2, with 0 being weak. There are 496,801 medium (1)
passwords, accounting for about 74% of all the passwords in the dataset.

As the data set is unbalanced with an approximately 1:6:1 ratio, the the accuracy is not
enough to establish which algorithm performs better due to the problem of overfitting, hence,
the confusion matrix is further used to calculate the F1-score in order to accurately evaluate
the models’ performances. Additionally, each model’s testing time was also noted.
During the pre-processing, the CSV file is loaded into a DataFrame. Then, the number of
missing values (NaNs) is identified and hence all missing values are deleted. The remaining
data is now converted into a numpy array and shuffled to avoid any biases that may exist in
the ordering of the dataset. Using a function for tokenization and the ‘fit_transform’ method,
the list of passwords is converted into a matrix of TF-IDF features.

3.2 Programming the Models
For this experiment, the training/testing split had to be the same for a fair comparison. Hence,
the train/test split was 80/20% for both models, meaning 535,711 passwords were used for
training and the remaining 133,928 for testing.
While programming the Random Forest model, the number of decision trees used in this
investigation is 10, specified through the ‘n_estiamtors’ parameter. The criterion is set as
‘entropy’, meaning that the algorithm will be using information gain based on entropy of
class labels to evaluate splits. With ‘random_state = 0’ the algorithm sets the random seed to
ensure reproducibility.

Similarly, an instance of the ‘LogisticRegression’ class from scikit-learn20
is used to develop
the Logistic Regression model. This instance, named as ‘log_class’, is the logistic regression
classifier used for predictions

1) F1 Score: calculated so that a single value can be used for comparison of the
algorithms to take into account a good average of the precision and recall21
. Hence,
the F1 Score indicates a good balance between correctly identifying positive cases and
avoiding false positives. A higher F1 Score means better performance22
. It is
calculated for each password strength classification for both the models

2) Prediction Time (seconds): Measured by the difference between the end and start
time for each model’s program. The values were calculated through the use of
Python’s time library, using the time.time() method23
. The start time was computed
after the training and the end time was computed after the testing. Therefore, the
lower the prediction time in seconds, the better the performance. The prediction time
was calculated as whole for both the models.

4.1 F-1 Score
The table below compares the classification performances of the Random Forest and Logistic
Regression with respect to the password strength. All values observed from the program were
rounded off to 4 decimal places for higher precision. Three trials were conducted because
both the models have randomness in their initialisation and training process; therefore
conducting three trials ensures that the evaluation is representative and not influenced by a
specific randomisation. This averaged result will, thus, be more indicative of expected
real-world performance.

4.4 Analysing Random Forest Performance
Figure 14: Random Forest Performance
My experiment indicates that Random Forest can predict password strength with very good
accuracy with a Macro F1 Score of 0.9684. The accuracy seems to increase as password
strength increases, however after medium strength there seems to be diminishing return in
accuracy, this may be due to the imbalance in the dataset. Nevertheless, the overall accuracy
from weak to strong increases from 0.9495 to 0.9695, therefore, the impact of the unbalanced
dataset on the model is minor. This may be the case as Random Forest can effectively handle
imbalanced data by assigning higher weights to the minority class24
during training, thus
improving classification of weak passwords. This property combined with its ensemble
nature are likely the reason for high accuracy.

19. A Comparison Study of Random Forest and Logistic Regression for Password Strength Classification
However, the pros of the Random Forest are also likely the reason for its poor time
performance25
of 0.7002 seconds, a 16 times slower performance in comparison to Logistic
Regression. Its ensemble nature constructs 10 decision trees, each which requires time for
optimisation and growth followed by a voting process.
4.5 Analysing Logistic Regression Performance
Figure 15: Logistic Regression Performance
Once again, the results indicate the same pattern of increasing and decreasing accuracy,
however the variations in Logistic Regression are much more significant. With a macro F1
score of 0.6746, the Logistic Regression model has an average accuracy. This may be due to
the fact Logistic Regression handles categorical features by encoding them26
, however, in the
case of passwords, the categorical variables have complex relationships, making it difficult
for the model to encode them. The unbalanced dataset may also be a huge contributor to
diminishing performance as unlike Random Forest, Logistic Regression can be biassed

towards the majority class27
and struggle to predict the minority classes as seen with the
lower F1 score for weak (0.3893) and strong passwords (0.7493). Despite its accuracy
limitations, Logistic Regression took the lead in prediction time with just 0.0439 seconds.
5. Conclusion
In this paper, the performance of Random Forest and Logistic Regression was compared
using the prediction accuracy and prediction time for classification of password strength.
While the inputted dataset for both the models was identical, differences in general trends for
prediction accuracy and prediction time emerged.
Overall, my experiment shows that Random Forest performs with better accuracy whereas
Logistic Regression performs with better prediction time. Therefore, a performance-time
tradeoff exists in both the models for password strength classification. Hence, the selection of
the model depends on the stakeholder’s priority. In case of lower computational resources and
large time constraints, Logistic Regression would be a better choice, whereas where accuracy
is the deciding factor, Random Forest should be used. Hopefully, this paper will prove useful
to developers who are looking to incorporate machine learning models for password strength
classification in their projects.
