Design of Attendance Ledger using Hyperledger Framework

Abstract

Attendance systems that exist currently are time consuming and vulnerable to modification.The attendance system proposed here is efficient and immutable, using facial recognition for marking and blockchain technology (BT) to secure attendance data.Though facial recognition for marking attendance has overtaken other biometric methods for its convenience, the program to mark attendance is not free from modification by some third party.The novel idea of using permissioned blockchain technology as the solution helps create an immutable privately-owned ledger in a distributed manner for storing attendance data where the code to automate the process of the attendance system is also immutable.
