Abstract
Biometric information from an initial sample is used to generate a biometric template for a user. The biometric template is split into multiple template shares using a polynomial secret sharing scheme, such that at least some threshold number of the resulting template shares must be combined to reconstruct the biometric template. After the biometric template is split, the resulting template shares are distributed to multiple components in the system, such as a server, and/or one more user devices, and the original copy of the biometric template is destroyed. To subsequently verify the identity of the user, the threshold number of template shares are obtained and combined to reconstruct the user's biometric template, and the reconstructed template is compared with biometric information extracted from one or more subsequently collected biometric samples. If there is a match between the reconstructed biometric template and the extracted biometric information, the user's identity is verified.
