A 3D LASER SCANNING DEVICE FOR OBJECT RESTORATION USING POINT CLOUD REGISTRATION
(Lead City University, 2022-12) Ahmed Abba Sheik
3D scanning of environments and the objects have a lot of practical uses. During the last decade increased performance and reduced cost has made them more accessible to larger consumer groups. The price point is still however high, where popular scanners are in the price range of 300,000 NGN-500,000 NGN. The objective of this thesis is to investigate the current 3D scanners in the market, considering both time-of-flight and triangulation in terms of accuracy and limitations and compare there results to build a more cost effective model of the 3D scanner at the end of the thesis. For validation purposes the constructed 3d scanner will be put through tests to measure its accuracy and ability to create realistic representations of its environment. The constructed model produced significantly less accurate results and scanning time was much longer compared to a popular competitor. This was mainly due to the cheaper camera sensor used for the model and not the mechanical construction itself. There are however many applications where higher accuracy is not essential and with some modifications, a low cost solution could have many potential use cases, especially since it only costs 1% of the compared product.

In today's rapidly evolving technological landscape, efficient and secure attendance tracking systems are essential for various organizations. This study introduces a novel solution that combines Radio-Frequency Identification (RFID) and Facial Recognition technologies to create a robust attendance management system. By leveraging the capabilities of both hardware and software components, this system offers a seamless and accurate approach to recording and managing attendance data. The hardware component of the system utilizes Arduino microcontrollers and RFID modules to provide individual identification through RFID cards or tags. Each user is assigned a unique RFID card that triggers the RFID module to record the attendance information. Simultaneously, the system captures facial images using a camera module for facial recognition. A Python program processes the data using Open CV, associating it with the respective user's profile and initiates the facial recognition process. The facial recognition system identifies users by comparing the captured facial features with the pre-stored templates in the database. The system offers several advantages, including high accuracy in attendance recording, enhanced security, and rapid processing of data. Moreover, the combined approach reduces the time spent on proxy attendance, ensuring the integrity of attendance records, and creating options for attendance. The system also provides real-time attendance tracking and generates comprehensive reports for administrative purposes. This research presents a step- by-step implementation guide for setting up the RFID and Facial Recognition Attendance System using Arduino and Python, making it accessible for educational institutions, businesses, and organizations looking to streamline attendance management. The system's effectiveness is demonstrated through extensive testing, highlighting its reliability and robustness. The system represents a cutting-edge solution for modern attendance management needs. By harnessing the capabilities of the technologies adopted, this system offers a secure, accurate, and efficient approach to attendance tracking, paving the way for improved organizational efficiency and data integrity.

(Lead City University, 2023-12) Afiss Emiola KAREEM
In recent years, analysis and interpretation of video sequences to detect and track objects of interest had become an active research field in computer vision and image processing. Despite significant efforts in object detection and tracking, an efficient method which provides high computational efficiency has not been developed. Hence, in this work a Hybrid Particle Swarm Optimization Convolution Neural Network (CNN-HPSO) technique was developed to improve computational efficiency in object detection and tracking. The video datasets (MP4 and AVi video formats) used in this work were obtained from a conventional online database and on a real-time basis from YouTube. Multiple frames sampled from the video clips were pre-processed and then segmented. An Enhanced Particle Swarm Optimization (HPSO) was formulated from standard PSO and was applied to Convolution Neural Network (CNN). CNN- HPSO technique was used for edge detection and extraction of the boundary of the image and the object tracking was finally carried out. The work was implemented using MatLab R2016 software. The average results of CNN-HPSO, CNN-PSO and CNN on the videos with MP4 format yielded processing time, accuracy, precision, FPR, sensitivity and specificity of 165.89s, 97.08%, 98.41%, 7.75%, 97.82%, and 92.25%; 179.52s, 94.25%, 96.99%, 10.37%, 95.23% and 89.62%; and 189.19s, 89.95%, 93.64%, 15.56%, 91.95.33% and 84.44% respectively. For the videos in AVi format, CNN-HPSO, CNN-PSO and CNN produced similar average results with processing time, accuracy, precision, FPR, sensitivity, and specificity of 185.09s, 96.62%, 98.23%, 7.80%, 97.34% and 92.19%; 198.24s, 94.83%, 97.62%, 8.56%, 95.46% and 91.43%; and 216.59s, 91.30%, 93.98%, 15.09%, 93.67% and 84.91% respectively. In this research, a CNN-HPSO with associated high computational efficiency was developed. The developed technique can be used for solving other related optimization problems.

A Mathematical Morphological Deep Neural Network for the Classification of Periapical Radiographs in the Diagnosis and Treatment of Dental Diseases
(Lead City University, 2022-12) Grace Lawumi TAM-NURSEMAN
One of the best ways to diagnose a disease in medical practice objectively is through medical imaging. The importance of medical imaging cannot be overemphasized. In dentistry, dentists often use radiographs, especially in ﬁnding hidden dental structure, bone loss, malignant or benign masses, and cavities that cannot be examined during a visual examination. The use of dental radiographs also helps dentists to detect hidden dental diseases early. This study is a continuation of previous work which bothered on the development of an expert system for the diagnosis and prognosis of 20 Common dental diseases using Bayesian network. The work was developed using several symptoms associated with dental disease for diagnosing dental diseases (D1- D20). The study was limited to symptomatic diagnosis which however has some obvious gaps such as the uncertainty in the reasoning associated with Bayes rule, the use of Pain as a parameter among others that were filled through the use of deep learning tools on dental periapical radiographs through an improved model. The improved model was developed integrating mathematical morphology (MM) operations (dilation, erosion, opening and closing) in the convolution layer of CNN, for data preprocessing and quality feature extraction. With its high sense of intelligence (artificial) obtained during training, the system receives dental images and analyses them automatically for various clinical findings with which 6 dental disease problems were solved. With an achieved accuracy of 99.78%, it can be established that this system can be used in dental clinics with high confidence giving very little or no-error-diagnosis. To make this system more scalable and robust, more dental diseases should nbe added through other MM based theory like lattice, topology and random functions other than set theory-based MM used in this study.

(Lead City University, 2023-12) Abimbola Basiru OWOLABI
Securing cloud-based information has become the most critical aspect in computing, owing to different methods adopted by attackers to steal vital information. Most system developers focus their information security on defensive mechanisms against attackers, this has proven to be inactive as attackers continuously explore ways to gain unauthorized access to cyberspace information, which has necessitated more effective, robust, and efficient models to mitigate threats posed by Cyber criminals. Hence, the design of an optimized web-based low-interaction Glastopf honeypot for the accurate gathering of Attackers' intelligence information and detection of fake honeypot systems using the OMNET++ Simulation tool. This study aims to assess the effectiveness of the Glastopf honeypot in collecting relevant intelligence on attackers, detecting fake honeypot systems, analyses the honeypot's ability to capture and record attackers' actions, including their exploitation methods, tools used, and payloads deployed. It also evaluates the honeypot's ability to provide valuable insights into attackers' motivations, intentions, and potential targets. An extensive experiment was conducted by setting up a virtual system with OMNET++ simulation running on Ubuntu web-server on the back end while on the front end was windows operating system where Glastopf honeypot was configured in a controlled environment. The study injects Hornet 40 data sets of attacks collected from six different cloud servers into the server to test Glastopf honeypot. Multiple attack scenarios were simulated, involving various types of attackers and attack vectors. The honeypot's logs, network traffic captures, and other relevant data are collected and analyzed using automated techniques. The results of the experiment provide insights into the Glastopf honeypot’s effectiveness in gathering intelligence information and make Glastopf honeypot a good cyber security tool, but would perform better when deployed with IDS and firewalls, thereby recommended for organizations but would not be suitable for individuals due to the installation technicality involved.

Automated Customer Support System (Chatbot) to Enhance Web-based Financial Application Services using Artificial Intelligence
(Lead City University, 2023-12) Roqib Akintunde AKINYEMI
Customer support is perhaps one of the main aspects of the user experience for online services. However, with the rise of natural language processing techniques, the industry is looking at automated chatbot solutions to provide quality services to an ever-growing user base. In view of this, the chatbot was developed using Artificial Intelligence Markup Language (AIML) java interpreter library Program AB (an experimental platform for the development of new features and serves as the reference implementation) which helps match input and output predefined in the AIML file. AIML was used to preprocess and train the bot using ready-made AIML file for Frequently Asked Questions. Also, vaadin was used to build a web user interface to interact with the trained AIML bot. Finally, a google script was written to translate from any language to English for the bot to understand and send the response in the preferred language of the user. Findings showed that the response time of the bot is dependent of the network, as the design gave a score of 70%, 80%, and 90% for load testing, stability, reliability testing and usability testing, respectively. Also, the bot is compatible with different operating systems, both for forward compatibility and backward compatibility having a score of 95%. The bot was able to answer customer questions, enquiries and complaints and the response time of the bot depends on the strength of the network since it is web based. Hence, the system provided a simple, cheaper, and durable customer financial and payment application service. It is therefore recommended that any company incorporating a chatbot should make sure that the chatbot is highly secure due to attacks and routine queries. It should also be standardised to deliver a high level of performance since chatbots will not be able to solve all queries.

based Predictive Model for Keylogging Attack Mitigation
(Lead City University, 2023-12) Mariam Ayobami GBADEGESIN
In the ever-evolving landscape of cybersecurity, the relentless progression of cyber threats presents an ongoing challenge to the integrity of sensitive data and user credentials. Among these threats, keylogging malware has emerged as a particularly insidious vector, adept at covertly infiltrating systems, stealing login credentials, and exfiltrating valuable information. This research is driven by the imperative need to confront this menacing adversary. By delving into the subtle intricacies of human keystroke dynamics, we have engineered a groundbreaking and intelligent predictive model aimed at the early and reliable detection of keylogging attacks. The innovative character of this model stems from its amalgamation of two powerful techniques: adaptive neural networks and fuzzy logic inference. This research develops a Neuro-fuzzy predictive model using keystroke dynamics to reliably detect and mitigate ongoing keylogging threats. The model’s training process was conducted using a diverse dataset comprising over three hundred thousand keystroke samples, sourced from both simulated users and actual keyloggers. Impressively, baseline neural networks exhibited a detection accuracy rate of 99.1%. Building upon this solid foundation, the specialized Neuro-fuzzy model further elevated precision, achieving a remarkable 99.62% accuracy. This enhancement primarily stemmed from the model’s ability to distinguish between human and automated keystroke patterns, significantly reducing false positives. These results demonstrate that an adaptive Neuro-fuzzy model can reliably predict keylogging attacks in real-time based on anomalous keystroke dynamics before significant credentials or data are exfiltrated. The adaptive model provides a robust predictive solution to a rapidly evolving risk that continues to bypass traditional reactive defenses.

Comparative Performance Evaluation of Random Forest on Web-based Attacks
(Lead City University, 2023-12) Oluwaseye Abayomi ADEYEMI
As human resources try to break into networks, control systems, and steal information with the help of expanding data communication paths and protocols, cyber intrusions are currently on the rise. The majority of typical online attack methods are thoroughly researched and documented. Countries, corporations, people, and vital infrastructures that depend on information technology for daily operations have suffered financial losses, the loss of personal information, and economic harm as a result of web-based intrusion. However, foreseeing an attack before it happens can aid in its prevention. This research proposes a predictive model for web-based attacks and a performance comparison of random forest with and without feature selection to secure the availability, integrity, and secrecy of networks, computer systems, and their data. The CIC-Bell-IDS2017 dataset, which includes typical and contemporary intrusion attacks, served as the raw data source for the proposed model. A python-based programming environment and interface for Anaconda Navigator, Jupyter Notebook, was used to create the predictive models. Performance evaluation and comparative analysis were conducted, and the results demonstrate that, once big data analytics (feature scaling and feature selection) were applied to the dataset, the models' prediction accuracies improved, creating a potential intrusion detection system. The outcome yielded excellent accuracy and model development times in both cases, with 97% and 98% precision for both sets and model development times of 35 seconds for the raw set and 15 seconds for the reduced set, which is an important factor when deploying machine learning models in a real-time setting. Random Forest is more computationally expensive than Correlation feature Selection-based classifiers, but having higher predictive accuracy, according to a comparison. Both of these methods work well and each has advantages and disadvantages. The use of big data analytics (PySpark) was found to help machine learning models perform better, resulting in better intrusion detection system.

E-Health Data Security Using Hybrid Encryption Techniques
(Lead City University, 2022-12) Ridwan Olayinka KOLAPO
The introduction of cryptography has brought plenty of improvement to health informatics, but not really employed in health institutes and this is often as a results of the protection issues that come together with the employment of e-Health systems. Security issues is taken into account a significant concern which is why health institutes still opt to follow the normal way of addressing health records. This study aim to ensure data security in health record using enhanced Ceasar Cipher, Affine Cipher and Red2 Cryptographic Techniques.This method used is considered a double enhanced encryption algorithm with a steganography technique because it combines an enhanced Ceasar encryption method with Affine Cipher encryption technique to enhance security of medical health records along with Red2 algorithm, which helps encrypt cipher-text messages and hide them in images. The integration of the enhanced Caesar and affine ciphers is as follows: First, each field in the record is encrypted with the enhanced Caesar cipher encryption method, and the encrypted output is used as the input for the affine cipher encryption method after-which the output of the second encryption phase is fed into the steganography stage and the final output of the developed system is presented as an image.The result of this study is presented as a software solution and also some metrics like accuracy, precision, recall and F1-score were measure to test the performance of the system and it shows that the enhanced ceasar cipher encryption technique used in this study has a larger computational time which compensate for the high level of security and also the image used for steganography resulted to having lesser image quality parameters as this also compensate for the addition security level. In conclusion, the main aim of cryptographic system and steganographic system is to protect the confidentiality of data both at rest and in transit. With the mix of the enhanced Ceasar Cipher method and Affine cipher alongside Red2 Algorithm, these techniques has helped to enhance effectiveness.

Electromagnetic Radiation and Spatial Proximity of Mobile Communication Base Stations: Analysis of Compliance in Sagamu Metropolis
(Lead City University, 2022-12) Olabisi Olayinka, ONALAJA
Electromagnetic radiation emanating from randomly selected 113 GSM Mobile Base Transceiver Stations (MBTSs) in different regions of Sagamu, Ogun State, Southwest, Nigeria, was assessed according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines, National Communication Commission (NCC), National Environmental Standards and Regulations Enforcement Agency (NESREA). This was to determine the exposure level at these MBTS and their compliance to setback distance in relation to the specification in the guidelines. Measurements of the maximum Power Density of radio signals were taken for sites operating in GSM 900MHz, GSM 1800MHz, WCDMA 2100MHz and correlated with the ICNIRP, NCC and NESREA specifications. The result indicated that only 23.9% (27) of the entire MBTSs complied with NCC regulations (5m) set back to the closest infrastructure, while majority 76.1% (86) of the MBTSs do not comply. 62.8% (71) of the MBTSs complied with the NESREA standard of 10 metres set back to the closest infrastructure while 37.2% (42) do not comply with the regulations as they do not observe 10 meters set back from the nearest infrastructure. Only 6.2% (7) of the total MBTSs in the study area, violated the recommended E(V/m) for 900MHz, GSM 1800MHz, WCDMA 2100MHz rates having a peak value of 85V/m. Also, 25.7% (29) of the total MBTS in the study area violated the recommended power density levels for 900MHz, GSM 1800MHz, WCDMA2100MHz rates having highest value for power density which is (47.75mW/m2) while others also showed high values ranging from 9.966 to 29.73mW/m2. These findings suggest that many MBST’s complies with NESREA (10m) setback regulation but violated the NCC (5m) regulation. Radiations emanating from the accessed base stations in some vicinity are in safe range specified in the guidelines and as such they do not constitute health risk in the short run. Mobile base stations whose RF radiation intensity is significantly high once identified, the settlers should be advised to relocate away from such base stations.

The aim of this study is to enhance end to end messaging security using image steganography technique. End to End SMS has always been dealing with security missues as there are no security measures being put in place to improve the Confidentiality of the context of the SMS. The Methodology used in this study implore the use of mathematical expression as the first step is to convert the secret message into binary and thus obtain a bitstream as the result of this step. then divide the obtained bitstream into a set of groups with three bits in each group. To this end, from the least significant bit, grouping is then done to every three continuous bits in a group. The result of this study is presented as a software solution, as it is implemented and tested for use. This study uses evaluation parameters like Mean square error and Peak Signal to Noise Ratio to measure the performance of the images that are used in the cause of this study, the images that are evaluated is the stego-image with text of different word-lengths embedded in it.

Enhancing Window-Based Congestion Control Algorithm for the Internet
(Lead City University, 2022-12) Matthew Ojo AYEMOWA
The Transmission Control Protocol (TCP) or Internet Protocol (IP) has gone through a number of changes. There have been numerous ideas to alter the mechanisms of TCP congestion control in order to improve its performance. Many research had been done on congestion avoidance and control; however, previous studies on window-based congestion control were mostly based on the starting network, adaptive congestion, and end-to-end mechanisms; however, network overloading will be avoided, and packet losses should be minimized by using the PERC Algorithm. The goal of this study is to develop a Proactive Explicit Rate Control (PERC) algorithm for max-min fair rates that avoids network overcrowding and packet losses through sharing. For max-min fair rates, we devised the PERC algorithm, which can prioritize short flows as needed. Motivated by the need for fast congestion control, this thesis focuses on a different class of congestion control algorithms, called proactive explicit rate-control (PERC) algorithms, which decouple the rate calculation from congestion signals in the network. The switches and Network Interface Cards(NICs) exchange control messages to run a distributed algorithm to pick explicit rates for each flow. PERC algorithms proactively schedule flows to be sent at certain explicit rates. They take as input the set of flows and the network link speeds and topology, but not a congestion signal. As a result, they converge faster and their convergence time depends only on fundamental” dependency chains,” essentially couplings between links that carry common flows, that are a property of the traffic matrix and the network topology. We argue that congestion control should converge in a time limited only by fundamental dependency Our main contribution is to use PERC Algorithm to control Network Overloading and to equally control packet loss In simulation and on a P4 programmed FPGA hardware test bed, s-PERC converges an order of magnitude faster than reactive schemes such as TCP, DCTCP, and RCP.
