In order to solve the problem in protecting privacy of remote identity authentication using fingerprint, a novel scheme based on Fingercode and homomorphic encryption is presented. In the proposed scheme, the server＇ s template is stored in the encrypted version while the server＇ s templates of the past schemes are plain, so its security is ensured. A protocol is designed to allow that the server and the user can jointly compute the Euclidean distance between the template and the query without releasing the private data. In the protocol, ＂pa...
