In all smart environments, biometric authentication is utilised to the utmost extent possible. The two most common methods for biometric authentication are face and fingerprint recognition. The combination of face recognition and fingerprint recognition can be installed in specific locations where a higher level of security is necessary. Typically, a camera and fingerprint scanner will be used to gather biometric data on the client side, and that data will then be sent to a Cloud Service Provider (CSP) to perform complicated tasks like face and fingerprint identification. In these circumstances, the transmission of facial photos and fingerprints from the client side to a server is a significant security risk since a hacker could attempt to steal that information and then use it to take over the authentication system. In this research work, a secure method for transmitting fingerprints and face photos using an encryption strategy that uses Reversible Data Hiding (RDH) is used. RDH is a technique for concealing information by employing a medium that makes it feasible to later recover the original images as well as the concealed message. To conceal the secret message in an image, an RDH via encryption strategy will combine the RDH process and the image encryption process into a single job. In this research paper, a new paradigm is suggested in which the compressed fingerprint data will be integrated into the facial image as a secret message using a Reversible Data Hiding technique. After RDH, the encrypted image that was obtained will be sent for additional processing to the cloud service provider.
