Key recovery definition

Key recovery. In this scenario, a user (on his own) uses his biometric data w to generate a random key R along with some public information P and then stores P on a (possibly untrusted) server. The key R is then be used, for example, to encrypt some data for long-term storage. At a later point in time, the user obtains a fresh biometric scan w′ along with the value P from the server; together, these values enable recovery of R (and hence enable decryption of the data). In the second setting the user is, in effect, running a key agreement protocol with himself at two points in time, with the (untrusted) server acting as the “communication channel” between these two instances of the user. This second scenario inherently requires a noninteractive (i.e., one-message) key agreement protocol since w is no longer available at the later point in time. Note also that any solution for the second scenario is also a solution for the first. Solutions for achieving secret key agreement using noisy data and an authenticated channel are known [BBR88, BBCM95, JW99, FJ01, LT03, DORS08]. Most of the existing work for an unauthenticated channel, such as [Mau97, MW97, Wol98, MW03, RW03], solves the problem only for two special cases: (1) when W = W ′ and (2) when W and W ′ consist of (arbitrarily-many) independent realizations of the same random experiment; i.e., W = (W (1), W (2), . . .) and W ′ =
