Optical Ciphering Scheme for Cancellable Speaker Identification System

Abstract

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

Innovative Hetero-Associative Memory Encoder (HAMTE) for Palmprint Template Protection

“…Other cancelable biometric systems are presented in [7,8]. The authors of [7] provided a cancelable method for speech recognition based on encryption algorithms.…”

“…An additional encryption algorithm is implemented using double random phase encoding (DRPE) to increase the security level of the encrypted signals. The proposed methodology was improved in [8] to protect the privacy of biometric data using cancelable biometrics where the data cannot be inverted so that the user information is kept private and secured. The authors suggested a hybrid algorithm based on the Fourier transform and Jigsaw transform.…”

A Cancelable Biometric System Based on Deep Style Transfer and Symmetry Check for Double-Phase User Authentication

“…The design of cancelable biometric transforms makes the recovery of the original biometric data a computationally hard process [8,9]. Several studies have been presented to generate cancelable biometrics [10][11][12][13]. Ratha et al [14] proposed a method for identification based on a cancelable geometric fingerprint framework.…”

Advanced 4f-based free-space optical system

“…18,19 Addressing this gap, our research introduces a novel optical hashing and compression paradigm, ingeniously leveraging the SWIFFT family of post-quantum hashing algorithms. [20][21][22][23][24][25][26][27][28][29][30] This innovative approach marks a significant leap forward, eschewing the conventionally employed slow, high-resolution CMOS cameras in favor of ultra-fast, signal-triggered CMOS detector arrays. The transition to these advanced detector arrays catalyzes a remarkable acceleration in information acquisition rates.…”

“…As computational power continues to scale, particularly with the looming advent of quantum computing, traditional cryptographic methods face potential obsolescence. [62][63][64][65][66][67][68][69] In this context, post-quantum hashing algorithms stand as a bulwark against future threats, ensuring that our data remains secure against even the most advanced computational attacks. 70,71 The implementation of this optical hashing and compression strategy engenders a suite of enhancements across the computational spectrum.…”
