Daofu Gong, Fenlin Liu, Bin Lu, Ping Wang, Lan Ding · 2008
A novel steganographic scheme is proposed in this paper to embed secret message into Java executable files. It analyzes firstly the format of Java class file, and then reorder the indexes of constants to embed messages. Expensive experiments show that the stego file modified by the proposed scheme still have the same file size and the implementation performance as cover. It is concluded that our scheme has the stronger covertness. Moreover, its maximum embedding capacity even amounts to 1/58.
