Among the various computer security techniques practice today, cryptography has been
identified as one of the most important solutions in the integrated digital security system …

We present a novel approach to generating cryptographic keys from biometrics. In our
approach, the PCA coefficients of a face image are discretised using a bit-extraction method …

Modern cryptography has one problem to be solved: key management. One proposed
solution is to bind biometrics with cryptographic key. However, the non-reproducible …

This paper proposes the mathematical formulation for the secure discretisation of
continuously variable biometrics. The secure discretisation of biometric data is based on …

This paper presents the mathematical formulation for the secure and versatile integration of
biometric data into a cryptographic framework. The use of Shamir polynomial thresholding to …
