Biometrics used for random number generation

Biometrics used for random number generation

Anotace: A lot of recent research focuses on the field of biometric key generation and “locking”, which promises to replace passwords by biometrics in the process of extracting a secret value from a secure storage. One of the major obstacles on the way to a reliable key generation technique is the variability in obtained biometric samples. This variability could be exploited for random number generation. The purpose of this thesis is to give an overview of some of the interesting results in the field of biometric key generation and “locking”, as well as to present a proposed method of generating random numbers from fingerprints and calculate the entropy of shift and rotation of fingerprints, which is seen as one of the contributing factors to the overall entropy of a fingerprint scanning. …víceméně

Zadání: The student will extend an existing review of work on generation of cryptographic keys from/with biometric data. The student will also review basic literature on truly random and pseudo random number generation.

It is a well-known fact that the biometric measurements for authentication purposes deal with a huge variability of input information already on the same biometric source. The aim is to collaborate with the supervisor and his team in the effort to develop and test robust method(s) which allow(s) building a statistical unpredictable seeds from small changes in different measurements on the same source – biometric-based data. The student will introduce the proposed method of generating random numbers from fingerprints and will estimate the entropy that is contributed by different positions of fingerprints. These will be supplied by the supervisor's team. …víceméně
