改进LSB算法以增加BMP图像信息隐藏量的方法

An Algorithm for Improving Imformation Hiding Capacity of BMP Image Based On LSB

LSB(Least Significantbits)算法是将待隐藏的信息嵌入到载体中最不重要的像素位上。本文对传统的LSB算法提出了改进,使用本算法后,信息隐藏量由原来的12.5%提高至25%。该算法通过VS2008编程试验。

LSB （Least Significant bits） algorithm is one of the basic method of imformation hiding. We propose an algorithm for hiding more information by analyzing the illumination formula which improves the LSB algorithm. The imformation hiding quantity increses from 12.5% to 25% by using this algorithm. This algorithm has also passed the test of VS2008 programme.
