Steganalysis of Data Hiding for Two-Dimensional Engineering Graphics Based on Characters Statistic
Fei Peng, Xingming Sun · 2008
Aim at information hiding methods for 2D engineering graphics based on characters, a Steganalysis algorithm is proposed. The entity set is firstly acquired from the engineering graphic, then a binary string is gotten from the entities' characters. After statistic analysis to it, a detection mode is built, which can detect if there exists any hiding information in a two-dimensional engineering graphic. Experiment results show that the proposed algorithm is efficient to detect the hiding information in the 2D engineering graphics based on characters.
