Security of Biometrics Authentication Protocols

In the last decade, biometric technologies for identification have been adopted and integrated by laptop mobile phones, cars, building access control, national identity cards etc. Biometrics are becoming increasingly common in establishments which require a high security level (departments of government, organizations). A highly biometric system which is very accurate is able to refuse the authorized users, to fail in the identifying process for accredited users, to wrongly detect users, or to afford unauthorized person be verified like known users. To solve this type of problems we will propose an authentication scheme which use chaos-based cryptography, and we hope that will resolve the actual problems raised by the modern and classic cryptography techniques. A next step will consist in launching new challenges for researching by using quantum cryptography. The success of biometrics technologies for personal identification is more comfortable because access, authentication and authorization are allowed based on a unique characteristic of an individuals physiological biological or behavioral feature.
