Efficient Generalized Selective Private Function Evaluation with Applications in Biometric Authentication

In a selective private function evaluation (SPFE) protocol, the client privately computes some predefined function on his own input and on m out of server's n database elements. We propose two new generalized SPFE protocols that are based on the new cryptocomputing protocol by Ishai and Paskin and an efficient CPIR. The first protocol works only for constant values of m, but has 2
