This paper proposes a reversible data hiding method that embeds an L-level data sequence to images in the spatial domain. Though reversible data hiding once distorts the image to hide data into it, the distorted image is completely separated to the original image and the hidden data. The proposed method uses only one parameter to embed and extract data, and it extracts data without any location map. In addition, it can control embedding capacity according to payload for suppression of embedding distortion. Simulation results show the effectiveness of the proposed method.
