Introduction

Fingerprint Recognition currently widespreads in numerous identity applications such as electronic ID cards, travel documents, access control and time attendance. Security issues with the condition of use of the authentication device is a major concern in such applications. various biometric systems are available on the market (optical, capacitive, thermal etc.). These systems if they are not protected can be sensitive to various attacks in particular with the use of false fingerprints.

GOALS

To have a large range of false biometric fingerprints.

•To develop methods of test and evaluations that are robust, reproducible and stable.

•To propose this method and test as standard in complement of the common criteria for the evaluation of the biometric sensors

Conclusion

•We are very powerful on false fingers manufacturing (rot-proof properties, softness during its lifetime, low cost etc..)

•These methods showed their effectiveness on the majority fingerprint capture techniques.

•However it exists protections in particular of aliveness detection which make it possible to be protected.
