A Cryptography based Face Authentication System for Secured Communication

Digital communication and networking had become an integral part of our everyday life. Technological advancements in Digital networking must also include security and confidentiality paradigms. Several previous works on communication systems comprised the problem of storage, sharing, and complexity of keys. On considering the mentioned problems of existing works, this paper proposes secure communication using cryptography and face recognition techniques with cloud computing. The proposed system pertains to a protected communication process, where messages are entitled only after the verification of the authorized sender and receiver using Linear Binary Pattern Histogram (LBPH) face recognition, and Rivest, Shamir, Adleman (RSA) cryptographic technique with the cloud management system. The system generates RSA key pair, which is exported as a Privacy- Enhanced Mail (PEM) file and stored in a remote server through a Secure Shell (SSH) tunnel.The proposed system has found that using 50 samples for face authentication is most efficient and accurate with limited time. Existing works have focused to increase security by adding layers of encryption which in turn increased the complexity to handle keys and decryption processes. This proposed methodology on following a biometric authentication system, stretches itself with an extra efficient layer of security without increasing the complexity of the system.
