摘　　要：在图像密文域中,信息完全表现会使处理器压缩像素对象时耗时延长,导致图像信息产生不可逆问题。因此,设计基于自适应编码的图像密文域可逆信息隐藏方法。按照图像数据帧同步标准,估算密文域内图像信噪比数值,以完成基于自适应编码的图像密文域调制。定义可逆信息标签,通过连续加密的方式,实现对图像信息的隐藏处理,完成基于自适应编码的图像密文域可逆信息隐藏方法的设计。实验结果表明,应用所提方法大部分图像密文域中的像素信息被隐藏起来,不会因信息完全表现而产生图像信息不可逆问题。In the image ciphertext domain,complete representation of information can prolong the processing time for compressing pixel objects,leading to irreversible issues with image information.Therefore,an image ciphertext domain reversible information hiding method based on adaptive encoding is designed.According to the synchronization standard of image data frames,estimate the signal-to-noise ratio of images in the ciphertext domain to achieve image ciphertext domain modulation based on adaptive encoding.Define reversible information labels and use continuous encryption to hide image information,completing the design of an adaptive encoding based reversible information hiding method for the image ciphertext domain.The experimental results show that most of the pixel information in the image ciphertext domain is hidden using the proposed method,and there is no problem of irreversible image information due to the complete representation of the information.
