Digital holographic-based cancellable biometric for personal authentication

Abstract

In this paper, we propose a new digital holographic-based cancellable biometric scheme for personal authentication and verification. The realization of cancellable biometric is presented by using an optoelectronic experimental approach, in which an optically recorded hologram of the fingerprint of a person is numerically reconstructed. Each reconstructed feature has its own perspective, which is utilized to generate user-specific fingerprint features by using a feature-extraction process. New representations of the user-specific fingerprint features can be obtained from the same hologram, by changing the reconstruction distance (d) by an amount Δd between the recording plane and the reconstruction plane. This parameter is the key to make the cancellable user-specific fingerprint features using a digital holographic technique, which allows us to choose different reconstruction distances when reissuing the user-specific fingerprint features in the event of compromise. We have shown theoretically that each user-specific fingerprint feature has a unique identity with a high discrimination ability, and the chances of a match between them are minimal. In this aspect, a recognition system has also been demonstrated using the fingerprint biometric of the enrolled person at a particular reconstruction distance. For the performance evaluation of a fingerprint recognition system—the false acceptance ratio, the false rejection ratio and the equal error rate are calculated using correlation. The obtained results show good discrimination ability between the genuine and the impostor populations with the highest recognition rate of 98.23%.

Optical multimodal biometric encryption that uses digital holography

“…Optical security techniques have also been used for securing biometric data, or to generate keys based on it for the protection of key personal data [22][23][24][25][26][27][28]. Biometrics comprise the unique biological traits required to establish the identity of a human being.…”

“…Biometrics comprise the unique biological traits required to establish the identity of a human being. If this information is compromised in any way, it is almost impossible to assign new security measures such as a password or keys, given that the subject possesses only a fixed number of biometric traits [22][23][24][25][26][27][28]. The development of secure and effective systems based on biometric identifiers are therefore in high demand, and an area of increasing interest among researchers.…”

“…Digital holography (DH) has played a significant role in the experimental implementation of optical encryption, as well as forming the basis for the development of alternative security schemes [10][11][12][13]. Due to the phase retrieval character of DH, it has proved well-suited to the development of biometric key-based security systems [22][23][24][25][26][27]. A cancellable fingerprint scheme has also been developed for authentication purposes during the course of experiments using optoelectronics based on DH [22].…”

“…Encrypted sensing has also been proposed, using DH for fingerprint images [23]. A security enhanced system with optically generated biometric keys has also been developed using DH [24,25]. In this method, keys generated frombiometric data are employed in both encryption and decryption procedures on the DRPE platform.…”

Securing information using optically generated biometric keys

“…On the other hand, different types of optical encryption schemes have also been reported in the area of information security using the joint transform correlator [20], interference [21] and digital holography [22][23][24][25][26][27][28][29]. The reported techniques based on digital holography are widely used for image authentication and data security [24][25][26][27].…”
