This paper presents a reversible watermarking scheme for the 2D-vector data (point coordinates) which are popularly used in geographical information related applications. This reversible watermarking scheme exploits the high correlation among points in the same polygon in a map and achieves the reversibility of the whole scheme by an 8-point integer DCT, which ensures that the original 2D-vector data can be watermarked during the watermark embedding process and then perfectly restored during… CONTINUE READING
