Design and implementation of an IoT based secure biometric authentication system
Annies Joshy, M. J. Jalaja · 2017
Authentication systems are used to verify the identity of a person and provide authorization for access. with the in creased number of Internet enabled devices in the modern world, reliable authentication is crucial for secure access in networked environments, Hence, a secure and reliable biometric authentication system based on IOT is proposed in this paper. The proposed biometric authentication scheme is based on iris recognition, as it provides better Accuracy and security, compared to other biometrics. In most authentication systems, user credentials are compared with locally stored database. It becomes in secure and inconvenient due 10 the physical access provided by local storage, and it is vulnerable to attacks or tampering, To mitigate this, IoT is used in the proposed system. For provide security to the data sent over the Internet, a hybrid encryption algorithm that combines Blowfish and RSA algorithms is used. The two-step authentication system provides enhanced security and reliability, The proposed scheme is developed and implemented as an embedded system, for secure employee authentication. Authentication is done using employee database and the Aadhaar database, which is an adequately secured one that contains validated data of all citizens in India. The system developed is found to be superior in terms of security and reliability, compared to existing systems.
