文本隐写术使用CALP较高的嵌入容量

近年来,一切都是趋势向数字化和互联网技术的迅速发展,数字媒体需要方便地在网络上传播。攻击,滥用或未经授权的访问的信息是十分关注的今天使保护通过数字媒体文件的一个优先考虑的问题。这要求我们设计新的数据隐藏技术保护和安全的重要意义的数据。。在这方面,隐写术通常首当其冲要考虑的隐藏信息的工具。隐写术是一个过程,包括隐藏消息在一个合适的载体如文本、图像或音频。这是希腊起源和“覆盖或隐藏的写作”。隐写术的目的是秘密通信。承运人可以被发送到接收器没有人除了验证接收机只知道存在的信息。大量的工作已经进行了不同的研究人员对隐写术。本文作者提出一个小说文本隐写术法通过改变英文字母字母的模式与较高的嵌入容量。 Considering the structure of English alphabets each two bits of the secret message has been mapped through some little structural modification of some of the alphabets of the cover text .This approach uses the idea of structural and feature changing of the cover carrier which is not visibly distinguishable from the original to the human beings and may be modified for other India language also. This solution is independent of the nature of the data to be hidden and produces a stego text with minimum degradation. Quality of the stego text is analyzed by trade off between no of bits used for mapping. Efficiency of the proposed method is illustrated by exhaustive experimental results and comparisons.
