Research of composite safety protection for digital maps
An adaptive watermarking technology for 2D electronic charts was proposed. It took count in the discrete wavelet domain scheme, and obtained an ideal embedding set for watermarks in the electronic chart space. In order to preserve topology of map effectly by the large embedding rates and protect the...
