Abstract
A server-side biometric authentication system is disclosed that can split data knowledge and processes, so that extensive collusion would be required in order for a fraudster to compromise the system. Biometric data provided by a user during authentication can be matched with a combination of pieces of a biometric template stored across two or more server(s), rather than on a consumer device as is typically done. More specifically, at the time of enrollment, a biometric template can be split into two or more fragments. Each of the fragments can be encrypted and stored on a template storage server. At a later point in time, during authentication, biometric data provided by a user (e.g., from a fingerprint) can be compared against a reconstructed version of the biometric template where each fragment of the template is retrieved from a matcher computer and combined together.
