基于分块灰度统计特性的空域鲁棒信息隐藏算法
A robust spatial information hiding algorithm based on statistic characteristics
摘要
Abstract
Proposed a new robust spatial domain information hiding algorithm based on statistic characteristics and chaotic system. The stable statistic characteristics at the significant position of spatial domain were used to help the process of the selection of cover space. Chaotic map increased the invisibility of secret message. The selection of cover space and the chaotic map both smoothed the contradiction between the fragility of secret message and invisibility of hiding. Experiment results show that this algorithm had good invisibility and also had the ability to resist many attacks, such as salt and peppers, cut, LSB, some least significant bit destroy, JEPG , Gaussian and so on. It had nice robustness, was better than conventional spatial domain information hiding algorithms.关键词
