图像中的信息隐藏技术

信息隐藏是进行产品版权保护的一种手段。从系统模型的角度研究了信息隐藏与检测的问题,提出了一种24位彩色图像隐藏与恢复的技术。该技术在空域将一幅待保密的彩色图像隐藏到另外一幅任意选取的足够大、可以公开的彩色图像之中,由所生成的图像可以无失真地恢复出原保密图像。根据Windows的位图文件存储与显示的特点和图像分存的方法,用VC编程语言设计实现的24位彩色图像隐藏与恢复系统,基本上能很好地实现上述功能。实验结果表明,所提方法对图像处理是稳健的。

Information Hiding Technology in Image

Information hiding is a kind of method to protect products copyright. The problem of information hiding and extracting is studied in the perspective of system model in this paper, a novel 24 bits image hiding and resuming technique is presented. This technique is to hide a image into a lager enough 24 bits BMP image that can be public and selected with random, and the hiding image can be resumed without losing from the generated image. According to the character of the BMP image's storage and display in Windows system and the divided storage of image, a system of 24 bits image hiding and resuming that designed by VC programming language can do these very well. Experiment result shows that the proposed technique is robust to common image processing operation .
