Design of Strong Password Algorithm based on Multiple Fingerprints

Abstract

As fingerprint is unique, relatively stable and easy to collect, fingerprint recognition appears on mobile phone, combination lock and online payment in recent years. Usually fingerprint is used only once to verify a lock or other forms of authentication, so if someone else gets the correct fingerprint, the lock will be unlocked easily. It is because of the easy acquisition, like getting by fingerprint ink or silicon film, fingerprints are easily picked up by thieves or other criminals. This paper aims to solve this problem by designing some strong password algorithms based on multiple fingerprints and lists some practical applications.
