Lossless Digital Watermarking Technology for Vector Maps

Abstract:

In ensuring the content of digital vector maps lossless, a high capacity digital watermarking algorithm is proposed based on encoding scheme. According to the structure of TAB file for digital vector maps, the watermark is hidden into the attribute blocks. As each vector object definition reserves redundant space, these information bits cannot be edited and displayed by any map editing tool, the watermark has good concealment. Experimental results show that the algorithm maintaining high capacity and good invisibility, it also can strongly resist various geometric transformations such as cropping, rotation, projection, etc..
