摘要：The most of the previous lossless data hiding techniques are that secret data are embedded into cover image. So, the relationship between the embedding capacity and PSNR of these techniques is always an inverse proportion. In contrast, the embedded position information of secret data are embedded into a location map in the proposed technique in order to achieve thedirectly proportional relationship. The proposed technique is based on a property of self- inverse in reversible function, it is the composite operation between reversible functions. In the embedding procedure, a stego image without distortion is generated using this property.In order to evaluate the efficiency and security of the proposed technique, the embedding capacity and PSNR are used in the experiments. In the experimental results, the embedding capacity and PSNR of the proposed technique are greater than it of the previous techniques.
