Bioinformatics Study Through Voice Technology

Biometric systems are used for security applications widely. The problems encountered with the biometric system are the single biometric verification dependence. The security problem arises from the original database's biometrics utilization. Biometrics are forever lost in the cases of database attacks. Cancellable biometrics is the emerging security trend to generate fake biometric versions through encryption or noninvertible transform methods for a security guarantee. Four biometrics comprise the unified biometric template for every person through Discrete Cosine Transform compression. The unified biometric template is encrypted through the Double Random Phase Encoding (DRPE) algorithm for the compromised database. The multi-biometric compression is performed through the significant coefficients under the DCT domain for the above four biometrics. The biometric recognition is accomplished through the unified biometric template decryption, and the cepstral approach is applied for the subject verification.
