Description: 提出一种基于统计特性的LSB密写分析方法,这种方法根据密写对原始数据统计特性的影响来判断秘密信息的有无.实验结果给出了不同阈值时的检测性能,当秘密信息量较大时,两类错误概率都可以得到有效控制.-This paper proposes a novel steganalysis technique based on the statistics method for LSB insertion, in which the change of statistical characteristic caused by information hiding is used to judge the presence of secret message. Numerical results show the performance of this developed method with different thresholds and, especially, both kinds of judgment error probability can be effectively controlled with the increase of embedded information.

Description: Simple steganographic techniques have been in use for hundreds of years, but with the increasing use of files in an electronic format new techniques for information hiding have become essential. This project implements the steganographic application such that the user you can embed a secret message or file inside a piece of unsuspicious information and send it without anyone knowing of the existence of the secret message. The receiver has to extract the message or file from the cover file using the same application. Except the sender and receiver, no one can even expect that the file contain some data, as the properties of the file are not changed after inserting the data. Platform: |

Description: Steganography is the art of hiding information in ways that prevent the detection of hidden messages. Steganography, derived from Greek, literally means “covered writing.” It includes a vast array of secret communication methods that conceal the message’s very existence - Steganography is the art of hiding information in ways that prevent the detection of hidden messages.
