Abstract
The chance of the question paper getting leaked is increasing day by day and a solution is proposed to solve this problem. Elliptic Curve Cryptography (ECC) along with QR code will be a solution to this problem. QR code (Quick Response) is the trademark for a type of matrix (two dimensional) barcode. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary and kanji) to store data efficiently. Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. ECC requires smaller keys compared to non-EC cryptography (based on plain Galois fields) to provide equivalent security. ECC technique involves conversion of text to cipher text. The cipher text is then converted to a QR Code. During decryption, the QR code is scanned and the content is decrypted. Only the application can read the original data shared in QR code since the data is encrypted with ECC with the integrity being maintained. An additional feature of linking the student’s answer sheet with hall ticket and question paper is also added to avoid paper frauds and making re-evaluation a simpler task. Once the evaluation is done, the examiner can then scan the code and enter the mark in the student database which is maintained by the university.
