A Multi Factor Authentication Approach Based on Biometrics, Optical Interference and Chaotic Maps

A novel method for user authentication based on multi factor approach is presented. For this security technique, a user authenticates into a system using a set of three characteristics related to physical, possession and knowledge factors. Biometrics authentication represents the physical factor. An optical authentication technique based on two-beam interference and chaotic maps complete the proposed scheme. In this sense, the seed of a chaotic map represents a user password corresponding to a knowledge factor and a resultant interferogram from an optical authentication technique represents the possession factor. Numerical simulation demonstrate the feasibility of our method. Moreover, we perform key space and statistical analysis to demonstrate the effectiveness of the solution.
