In terms of the restrictions among the performance criteria of dynamic graph-based watermarks,looking for the balance of these criteria,satisfying the characteristics of an ideal watermarking graph,this paper summarized the encoding technique of software watermarking,proposed an improved encoding scheme.It took advantage of the two dimensional PPCT:high error correction capability,good resistance to attack and high date-rate of Radix-K,through importing mix encoding and add point area.The experimental results show that this scheme has high date rate and robustness,optimal overall performance,it's a good scheme.
