Description: 由于通过RS统计分析和Chi-squate统计分析,可以察觉以LSB方法密写的秘密信息的存在,因此为提高密写方案的安全性,提出了一种改进的LSB密写方案,即如果被嵌入的秘密比特与原始灰度的最低位相同,便不作改动 否则根据周围像素作增1或减1的调整,而在接收方,只需将载体图象的最低位取出即可恢复秘密信息.大量图象的模拟实验结果说明,该方案不仅可以抵抗RS分析和Chi-square分析,而且不增加失真度,并可保持计算量小、提取方便的优点.并表明改进方案对抵抗这两种密写分析是有效的.-RS and Chi-square analyses are powerful steganalytic techniques for detecting the presence of secret information embedded in the least-significant-bit(LSB) plane of digital images. This paper describes an improved LSB steganographic scheme that can effectively resist both RS and Chi-square analyses without sacrificing perceptual quality of the cover image. In the described steganographic technique, a pair of mutually complementary mappings, F1 and F-1, is used, leading to a balanced behavior of ...

Description: This report describes the transformation techniques to generate non-uniform random numbers with the exponential, normal and arbitrary distributions. These are generated by random number generator, which is referred to as multiplicative congruential generator or as Lehmer s generator. Then randomness of the generated distributions is tested by graphically and by chi square test.
