Lossless Data Embedding in the Spatial Domain

A lossless data embedding method that inserts data in images in the spatial domain is proposed in this paper. The proposed method restores the original image as well as extracts hidden data from an image in which data are embedded. One and only one parameter based on statistics of pixels is used to embed and extract data. This method requires neither any reference images nor memorization of positions of pixels in which data are hidden to extract embedded data. In addition, the proposed method can control the payload of hidden data and the quality of an image conveying hidden data by controlling the parameter. Simulation results show the effectiveness of the proposed method
