  • Abstract:
  • Biometric characteristics are largely immutable, i.e. unprotected storage of biometric data provokes serious privacy threats, e.g. identity theft, limited re-newability, or cross-matching. Once compromised, biometric traits cannot be canceled or reissued. To handle above issues in case of behavioral biometric-signatures, I propose to generate a non-invertible cryptographic key from cancelable online signature templates. Initially, a noninvertible transformation is applied on the grid and texture features extracted from online signatures. Subsequently, the transformed points form cancelable templates which are then utilized to generate a unique non-invertible key. As the cryptographic key generated is non-invertible, it is highly infeasible to acquire the cancelable signature templates or the original signature from the generated key.
