Various template protection techniques have been developed in the past few years, among which cancelable biometrics is a very popular and efficient one. It uses a noninvertible transformation to map an original template to a transformed domain to prevent the recovery of the original template from a compromised transformed template. Generally, cross-template attacks over cancellable template schemes are evaluated through statistic independence metrics. In this paper, the authors investigate approaches to launch attacks through cryptanalysis.
