2010/8/31
在WWW图像搜索引擎中，如何快速而准确地检测出近似或重复图像已经成为亟待解决的问题,提出一种基于MD5的近似图像检测算法。该算法选取图像分块灰度均值为特征，经过拉普拉斯特征值降维，矢量量化后，图像特征被转换为MD5值，然后根据生成的MD5值进行近似或重复图像检测。实验结果表明该算法是有效的。

MD5算法 敏感数据 篡改检测
2009/7/17
针对数据库中敏感数据被非法篡改后难以检测发现的问题，提出了一种基于单向散列算法的不可逆性对敏感数据篡改的有效检测方法，并采用检测客户端与服务器的双重检测机制来加强检测效果。单向散列算法选用MD5算法，并通过向算法中注入隐蔽的“抗体”因子以抵抗篡改者的穷举搜索，使MD5算法得到有效的改进。重点阐述了上述检测方法的原理及其在应用系统中的实现。应用结果表明，该检测方法对非法篡改具有高度敏感性和优秀的数据...
