This paper proposes a reversible data hiding method that embeds data into specific areas such as image edges. Though a reversible data hiding method distorts an original image to hide data, it not only extracts hidden data but also restores the original image from the distorted image. The proposed method memorizes only one parameter for data extraction and image restoration, and no location map recording watermarked positions is required. By simple modification to the conventional method that has the above mentioned features, the proposed method has a new function;hiding data to only specific areas.
