JPHide 和JPSeek 的源代码
应用背景JPHide 和JPSeek 的源代码!JPHide&JPSeek是一个JPEG图像的信息隐藏软件!-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

CRF 工具包及使用教程
CRF的工具包,实现原理,及样例。CRF(Conditional Random Field) 条件随机场是近几年自然语言处理领域常用的算法之一,常用于句法分析、命名实体识别、词性标注等。在我看来,CRF就像一个反向的隐马尔可夫模型(HMM),两者都是用了马尔科夫链作为隐含变量的概率转移模型,只不过HMM使用隐含变量生成可观测状态,其生成概率有标注集统计得到,是一个生成模型;而CRF反过来通过可观测状态判别隐含变量,其概率亦通过标注集统计得来,是一个判别模型。由于两者模型主干相同,其能够应用的领域往往是重叠的,但在命名实体、句法分析等领域CRF更胜一筹。当然你并不必须学习HMM才能读懂CRF,但通常来说如果做自然语言处理,这两个模型应该都有了解。

RSA加密算法
Rivest、Shamir 和 Adleman设计了一种算法,可以实现非对称加密。这种算法用他们三个人的名字命名,叫做RSA算法。从那时直到现在,RSA算法一直是最广为使用的“非对称加密算法”。只要有计算机网络的地方,就有RSA算法。
