An Encryption Approach Using Information Fusion Techniques Involving Prime Numbers and Face Biometrics

Abstract

The work shows a novel solution to create an access key which can be used within the transactions of electronic currencies, blockchain as well as in the field of computer security to guarantee a high level of secrecy, but also, with a high level of certainty, to provide a person identity through Information Fusion (IF) techniques and biometric data encryption. Specifically, two non-connected areas have been joined, Face Biometrics and Public-key Cryptography. This choice was taken in order to get through the limits these two approaches have found singularly and to give a suitable solution in the context of electronic and digital exchanges (electro-currencies, Internet of Things). An innovative and original algorithm has been developed, which can do fusion operations between Face Biometrics and numerical data, that is an algorithm of Hybrid Information Fusion, named FIF (Face Information Fusion). We decided to use a digital face as a biometric component, and the product of two prime numbers as a numerical component, that is the module in RSA algorithm.
