Exploring concept of QR code and its benefits in digital education system

Abstract

This research paper concentrates on the concept of Digital Authentication using QR Code in Digital Education System. This paper aimed to provide a better solution to the Digital Security. There are two challenges of the work i.e. first one is to explore the usability of QR Code in general life and second is to incorporate QR Code technology with an educational document for security to avoid duplicity. The literature review is done to synthesis digital encoding and decoding technique as well as basics of Bar Code and QR Code. The implementation of QRC (Quick Response Code) for verification is presented where web environment, programming logics, and URL embedding are discussed. The result analysis and testing of experiment are done in the sense to get best quality of QR Code though the information embedded should not affected and the QR Code must easily be decoded the embedded information from common tools. The goal of this research paper is to explore and analyze the best image under the testing of Error Correction Level and Matrix Point Size parameters by calculating the PSNR and MSE values for QR Code images with different image file format (PNG and JPG). The calculated values are compared and the final conclusion of the work found which state that the PNG image with Error Correction Level-L and Matrix Point Size 1 are the best to generate quality QR Code. The testing and result are presented which state that the QR Code is the best way to compose the identical information of any entity to quickly figure out the originality.
