摘　　要：传统信息隐藏方法是直接将秘密图像隐藏到载体图像中,隐藏深度不深、方法单一、容易分析,而且隐藏的信息量较小。提出了一种通过图像混合和小波变换两次隐藏将彩色秘密图像深度隐藏到彩色载体图像中的信息隐藏方法。仿真实验结果表明,该方法具有很好的隐蔽性,隐藏的信息量大,且能够有效抵抗直方图统计分析,隐藏方法复杂,分析困难。The traditional information hiding method is hiding secret image into vector image,hidden depth is not deep,the method is single and easy analyzed,the hidden information capacity is small.This paper proposes an information hiding method through image mix and wavelet transform double information hiding methods,it hides color secret image into color vector image.In the simulation results,this method has very good hidden feature,the large hidden information capacity and resisting statistical analysis feature,the method is complex and difficultly analyzed.
