摘　　要：针对在加密域中进行指纹匹配时指纹模板和现场样本整体对齐的困难性,提出了一种免对齐的指纹匹配方案.采用具有旋转和平移不变性的细节点纹线方向特征和细节点局部结构,设计实现了相应的加密二进制电路,使得服务器能验证用户指纹,而不会泄露各自的数据.实验结果表明,所提方案在FVC2002-DB2指纹库上具有较高的匹配精度.When a server authenticates users based on fingerprint over open network,the process of fingerprint matching is usually handled in the encrypted domain with purpose of protecting the privacy and security of both parties. However,an accurate alignment of the template and the query sample is rather difficult in this situation. An alignment-free fingerprint-matching scheme was presented,which extracts two kinds of local features around the minutiae,ridge orientation and minutiae local structure. Both features have the properties of invariant to rotation and translation. Garbled circuits were designed to implement the corresponding matching algorithm,which allow the server to verify the user without leaking the respective data. Experiment shows that the scheme achieves a relatively higher accuracy on FVC2002-DB2 public database.
