摘要
为了进一步增强用户指纹特征信息的安全性,提高处理效率,文中提出了一个典型的用户指纹特征模板信息保护方案,文中分析了该方案存在的安全隐患和运行效率问题,指出了其存在的缺陷,针对存在的缺陷提出了一种新的改进方案,并对改进方案进行了详尽的阐述。改进方案能大大提高用户指纹特征信息的安全性,同时能显著提高运行效率。改进方案适用于对安全性以及运行效率要求均较高的应用场合。
In order to further enhance the security of user＇s fingerprint characteristics and improve processing efficiency, a typical user＇s fingerprint feature information protection scheme is proposed, its security risk and operational efficiency analyzed, and defect pointed out. And for these, a new improved scheme is proposed and described in detail. The improved scheme could greatly enhance the information security of the user＇s fingerprint characteristics and significantly raise the operation efficiency. This improved scheme is suitable for the applications with high security and operational efficiency
