MD5计算,可以将文件提取出摘要，进行比对，校验，实现指纹算法-MD5, can be extracted document summaries, compare and testing to achieve fingerprint algorithm

通过指纹比对来探测操作系统版本，比NMAP牛，更比NMAP精确。,By fingerprint matching to detect the operating system version, than the NMAP cattle, more accurate than the NMAP.

指纹对比系统，通过将扫描的两副指纹照片进行比对，可以分析出其中的不同，主要是像素点的对比，结合了一些算法-Fingerprint comparison system, by scanning the fingerprint of the two photos to compare, you can analyze the different pixels are mainly contrast, combined with a number of algorithms

MFC下的指纹考勤系统，包括了单个指纹比对模块。对指纹考勤系统所用到的算法进行封装。-MFC under the fingerprint attendance system, including a single fingerprint matching module. Fingerprint time and attendance system used by the algorithm package.
