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 is embedded into a location map in the proposed technique in order to achieve the directly proportional relationship. The proposed technique is based on a property of self-inverse in reversible function; it is the composite operation between reversible functions.
