Abstract : We introduce a new way for generating strong keys from biometric data. Contrary to popular belief, this leads us to biometric keys which are easy to obtain and renew. Our solution is based on two-factor authentication: a low-cost card and a biometric trait are involved. Following the Boneh and Shacham group signature construction, we introduce a new biometric-based remote authentication scheme. Surprisingly, for ordinary uses no in- teractions with a biometric database are needed in this scheme. As a side effect of our proposal, privacy of users is easily obtained while it can possibly be removed, for instance under legal warrant.
