Optical Ciphering Scheme for Cancellable Speaker Identification System

Most current security and authentication systems are based on personal biometrics. The problem is a major issue in the field of biometric systems. This due to use databases original Then biometrics will forever be lost if these attacked. Protecting privacy most important goal cancelable In order protect privacy, therefore, should non-invertible such way that no information can inverted from templates stored identification/verification databases. One methodology achieve non-invertibility employment transforms. work suggests an encryption process for cancellable speaker identification using hybrid system. system includes 3D Jigsaw transforms Fractional Fourier Transform (FrFT). proposed scheme compared with optical Double Random Phase Encoding (DRPE) process. evaluation simulation results shows algorithm secure, authoritative, feasible. cancelability effects good reveal performance. Also, it introduces recommended robustness levels its utilization achieving efficient
