A Steganographic Algorithm Based on Hamming Code and Wet Paper Code
一种基于汉明码和湿纸码的隐写算法

Dividing the cover image into matrix blocks, using the pixels in the matrix blocks repeatedly, this paper constructs a new double-layered steganographic algorithm based on Hamming code and wet paper code. For each matrix block, the secret message is first embedded by using Hamming code in rows. Then according to whether the previous embedding result is influenced or whether 3 changes are needed when embedding message in columns, the notation of dry and wet is introduced. Finally wet paper code is used for s...
