Biometric authentication methods are one of three approaches currently used. They offer a lot of benefits as well as they have few disadvantages. One of these disadvantages is low level of flexibility. Itpsilas not possible to change your biometric characteristic or even to increase number of your characteristics. This could be problem if we consider many systems with different level of security. Corruption of system with low level of security could help attacker to gain access to system with higher level of security. Solution of this problem could lie in use of behavioral biometric. The article introduces challenge-response approach in this area. We discuss possibilities of challenge-response biometric authentication and show new behavioral biometric suitable for this approach - visual evoked potentials. We give description of physiological features of this characteristic, discuss this properties and usability. We try to answer the question if itpsilas suitable only for liveness testing or itpsilas possible to use it for full authentication. Further we present design of prototype challenge-response biometric authentication system which takes advantage of visual evoked potentials.
