We consider the secure biometric storage problem and develop a solution using syndrome codes. Specifically, biometrics such as fingerprints, irises, and faces are often used for authentication, access control, and encryption instead of passwords. While it is well known that passwords should never be stored in the clear, current systems often store biometrics in the clear and are easily compromi...

We describe a method to encode fingerprint biometrics securely for use, e.g., in encryption or access control. The system is secure because the stored data suffices to validate a probe fingerprint but not to recreate the original fingerprint biometric. Therefore, a breach in database security does not lead to the loss of biometric data. We present a model for a secure biometric system for which...

Biometric authentication methods are gaining popularity due to their convenience. For an authentication without relying on trusted hardwares, biometrics or their hashed values should be stored in the server. Storing biometrics in the clear or in an encrypted form, however, raises a grave concern about biometric theft through hacking or man-in-the middle attack. Unlike ID and password, once lost...

Cryptography is used for security and authentication of data. Therefore it is used in biometrics system for keeping it safe and away from frauds. When we are using biometrics we ensure that, it is specially used for authentication and verification for the person’s template. This template can be misused if it is stolen by any nonauthenticate person. Focusing on biometric template security is the...

As applications of biometric verification proliferate, users become more vulnerable to privacy infringement. Biometric data is very privacy sensitive as it may contain information as sex, ethnicity and health conditions which should not be shared with third parties during the verification process. Moreover, biometric data that has fallen into the wrong hands often leads to identity theft. Secur...

Preserving the privacy of digital biometric data stored in a central d...

Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric to be compared in protected way, revealing only the comparison result when private key known. This very useful for non-device-centric authentication architectures with clients provide data and external servers authenticate them. While many reported solutions do not follow standards are resistant quantum...

The continuous dependence on electronic media has radically changed our interactions, many of which are now performed online. In many occasions users need to authenticate to remote machines, but the hostile environment of the Internet may severely expose users and service providers. To counter these shortcomings, strong authentication is pushed forward. As a means to authenticate individuals, b...
