摘要
应用VC++实现一种简单易行的LSB算法,该算法将水印图像的二值数据嵌入目标图像的最低有效位,从而达到隐藏信息、标记图片的作用。同时文中还简要分析了BMP文件格式,并着重讲解了LSB算法的核心思想。最后,对应用算法实现的程序进行了测试,测试结果表明该算法具有良好的隐蔽性和高保真性。
In the article a very practical and easy LSB algorithm is realized by VC＋＋,embedding the binary data of a image into the least significant bits of a target-image,attaining a function of concealing the information and marking image.And in this article the format of bitmap file is analysed,the main content of LSB is emphasised.At the end,I have tested the program based on the algorithm,and the resut represents a hiden and high-fidelity character.
