摘要:

基于改进的FEMD算法提出了一种可逆秘密图像共享方案。首先改进秘密数据的嵌入过程,使原始像素对和嵌入后含密像素对成为一对一的映射;然后通过设置溢出标识位来记录溢出像素对的原始值并进行相应处理。实验数据和分析表明,所提算法可以在保证生成高质量的含密图像的同时,解决不能恢复原始载体图像的问题。

Abstract:

Based on the improved FEMD algorithm an invertible secret image sharing scheme was proposed.Firstly,the embedding process of secret data was improved to make the original pixel pair and the stego pixel-pair to become a one-to-one mapping.Then a unique status flag was set to be calculated to record and process the original status of the over flow pixel-pair.Experimental data and analysis show that the proposed algorithm can guarantee the generation of high quality cryptographic images and solve the problem that the original carrier image can not be restored.

Key words: secret image sharing, steganography, FEMD, stego image
