Executive Summary

Software watermarking is a tool used to combat software piracy by embedding identifying information into a program to claim the ownership. One of the most effective watermarking techniques proposed to date is the Dynamic Graph Watermarking (DGW) scheme of Collberg et al, which is resistant to attacks such as optimization and obfuscation. Currently, three main topologies that DGW adopts include Radix-k, PPCT (Planted Plane Cubic Tree) and Improved PPCT (IPPCT) structures. Palsberg in his literature not only gives the relationship between the PPCT (Planted Plane Cubic Tree) structure and the integer but also establishes the PPCT enumeration encoding mode.
