A New Method of Key Management Based on Iris Biometrics
Zhang Xiang-d · Microcomputer Information · 2008
A convenient and safe key management means which based on iris biometrics is given. When the key is saved,the user’s key is integrated into the iris code by generalized regression neural networks. The user only needs to save the parameters of the trained neural network and the XOR of the key and a output of the GRNN,while both the key and the iris code are discarded. To get the key again,the user just need to sample and input his iris biometrics into the neural network,if the iris code is correct e-nough,the system will release the key. The system is safe,even if the attacker thieves the template,the information of the key or iris biometrics will not be betrayed.
