- Abstract
- Biometric template security is an important issue because compromised biometric templates cannot be revoked and unprotected biometric templates leads to privacy risks. This paper proposes a biohashing method for fingerprint templates protection using non-invertible orthogonal transformations. Fingerprint images are converted into random bitstring. The proposed method enables to carry out the matching in the transformed domain.
