The connection of a Blockchain with Students’ Attendance Register based on Security Cameras

Abstract

These days, security cameras perform surveillance tasks in institutions of education. Thanks to the utilization of analytic functions, such as headcount, face detection, face recognition, and the Black and White List, a possibility is given for composing an attendance register of the students visiting the lectures.To attain secure data storage, the utilization of decentralized blockchain technology is expedient. The most optimal solution is that the university would constitute a blockchain, so the institution would regulate the rules of the operation itself.To link the blockchain with the NVR (Network Video Recorder) unit, and to have the attendance register composing system running, a smart contract is to be implemented in practice. By the closing of a smart contract, great care should be applied to the input of valid data.
