摘要
描述了一种基于新型嵌入矩阵的多媒体信息隐藏方法,即通过构造一种新型数据嵌入矩阵,在修改数据少于■比特的前提下,在长度为2m比特的可修改数据中嵌入m比特的秘密数据。实验结果表明,该方法可实现较大的数据嵌入容量,且嵌入后的图像、视频质量较高。
This paper presents a method of information hiding based on a new embedding matrix. By constructing n new embedding matrix and changing less than ■ bits cover data, m bits secret data can be embedded into a 2 m bits cover data. The experimental results shows that the proposed method can achieve higher data-embedding capacity, good quality of marked image or video.
