In the field of information security, Crypto-Biometrics is an advanced technology. Data pro-tection and its secure transmission remain a topmost priority in the current digital era. In recent times, data breaches have become a major issue which affects the organizations across various industrial sectors. In this context, this review on crypto biometrics aims to provide an extensive overview of recent developments in the field of crypto biometrics especially in the area of fingerprints, iris and DNA technologies. The survey provides a comprehensive analysis of the latest development in crypto-biometrics that further focuses on integrating biometrics technology with various cryptographic methods to improve security and privacy. Compared to biometric template, Various algorithms such as advanced encryption standard (AES), triple data encryption standard (3DES), Twofish, Elliptic Curve Cryptography (ECC), Elgamal cryptosystem and Diffie-Hellman key exchange are commonly utilized for encryption, decryption and key generation with enhanced security and privacy. Additionally this review reports various methods and algorithms to improve biometric recognition under various constraints. The study emphasizes the effectiveness and summarises those algorithms with their limitations. Major developments in cancelable biometrics, multi model biometric systems and cypto-bio keys generation are also reviewed in the study. The Survey also addresses several challenges related to biometric template protection, revocability and privacy concern while proposes possible solutions that linked biometrics to cryptography. This comprehensive survey outlines the importance of crypto biometrics for securing sensitive information in the modern digital era. This review also identifies potential areas for further exploration by the researcher.
