Abstract
Identification of students in higher institutions in Nigeria, coupled with the recent insecurity and impersonation in the country has exposed the need to find a way to identify each and every person in the institution and Cross River University of Technology (CRUTECH), Calabar, Nigeria, is not an exception. The current method of identifying students with an identification card is vulnerable to abuse. To curtail this menace, this research proposes an IOT-based attendance system using ESP32 microcontroller, 0.96” OLED display and R305 fingerprint module. During operation, the system collects the fingerprint data from multiple users through the microcontroller based on ESP32 Wi-Fi enabled module and sends it over the internet to a website. Enrollment of fingerprints is done on the server using the interfaced fingerprint sensor module. Verification of user’s fingerprint is done on the webserver while fingerprint templates are transmitted over Wi-Fi. The website user interface (UI) used in this project is developed using PHP, CSS and JavaScript. It has a database and records of attendance. By logging into the website, attendance records of each user, including personal details as well as incoming and outgoing time can be collected. This data can be downloaded and exported to an excel sheet for evaluation.
Highlights
The method of identifying students in institutions in Nigeria is by registration numbers, students’ identity (ID) cards, fee clearance cards, photo cards, among others, but with its inherent problems
A controlled environment is critical to institutions [3][4] and to provide a safe and secure environment on campus, biometric security system is key
A digital multimeter is used in the testing of the circuit components to ensure that all connections were done properly
Summary
The method of identifying students in institutions in Nigeria is by registration numbers, students’ identity (ID) cards, fee clearance cards, photo cards, among others, but with its inherent problems. Biometric security should be used to authenticate student’s access to libraries, hostels, course registrations, classrooms for lectures and examinations This will tackle truancy, eliminate identity fraud, verify students’ activities within the campus and curb examination malpractices. Students, staff and recurring visitors should be accurately time-stamped and identified, creating an irrefutable record of one’s total activities within the campus. This will guarantee safety and the potential security breach that puts student’s lives in danger will be eliminated. The nexus of this research is to design, construct and implement an IOT-based biometric system with a view to curbing insecurity in Cross River University of Technology, Calabar and other institutions in Nigeria
