Aiming at the problem of low recognition rate and poor security in the process of palmprint identity authentication, a cancelable palmprint template generating algorithm is proposed, which is based on local Gabor directional pattern with adaptive threshold by mean (mLGDP), difference local Gabor directional pattern with adaptive threshold by mean (mDLGDP) and feature fusion of them. In this method, the feature code of the image is segmented and the fea-ture vectors are extracted and binarized. Then the Bloom filter is used to achieve many-to-one mapping and the location scrambling of palmprint image. Finally, the scrambling result matrix and the user key are irreversibly transformed by the convolution operation to obtain a revocable template of the palmprint image. Both theoretical and experimental results analysis show that, in the case of key loss, the method of feature fusion can enhance the diver-sity of the original palmprint template effectively, improve the recognition rate efficiently, and have better security. 相似文献

为了增强用户身份认证机制的安全性,在传统的口令认证方式的基础上,提出了一种基于模糊逻辑的击键特征用户认证方法。该方法利用模糊逻辑对用户输入口令的键盘特征进行分析鉴别,并结合用户口令进行用户身份认证。该方法有效弥补了传统的口令机制易被攻击的缺点,有一定的实用性。 相似文献
