摘要/Abstract

摘要： 将指纹细节点和密钥进行绑定，并用fuzzy vault方法对结果进行保护。在密钥恢复时，用GRS解码进行纠错处理。对GRS的传统解码和表单解码的效果进行了比较，实验表明表单解码比传统解码的密钥恢复效果更好。

Abstract: In this paper，an implementation of fuzzy vault based on minutiae is carried out.When the key needs to be recover，GRS decoding is used to perform error correction.The performances of two decoding methods，traditional and list decoding are compared.The experiment shows that the latter has better effect.
