Abstract

This study aims to develop a timekeeping system by face recognition using

Adaboost algorithm. The main objective of the project is to develop a face recognition

timekeeping system that can be used as automated timekeeping which is very accurate to

use by companies nowadays. The companies’ system working hours of employees will be

corrected and will improve work effectively. The timekeeping system checks employee’s

log in and log-out whenever they accessed their company’s biometric machine. Rapid

Application Development Methodology (RAD) was used to develop the system. The project

utilized Unified Modeling Language (UML) to build the models of the system through use

case, activity, sequence, and class diagrams to design the database scheme. C#

programming language is used by the proponent to be able to construct the system

together with the Microsoft SQL serves as database for storing the data of the system.

Questionnaires are used for measuring the efficiency of the proposed system as

evaluated by the end-users based on the ISO 9126 standard, the results of the rating given

by the evaluators.

The system will bring users a timekeeping system with friendly interface, especially

the system was built based on current reality in Viet Nam. The proponent is confident and

believes that this project study has satisfied its objectives and purpose.

Key words: timekeeping system, face recognition, AdaBoost.
