A large-capacity steganography for MIDI files characterized by anti-steganalysis ability
Li Guo · 2010
A new steganographic algorithm for MIDI files was proposed.This algorithm achieved a strong anti-steganalysis ability by reducing the modification of the statistical characteristics of orginal data.On the other hand,the algorithm embedded secret messages in both time and velocity parameters,and determined adaptively the position of bits in each parameter for the embedding of secret messages.Experiement results show that the effect of the proposed algorithm on sound quality is almost neglectable and that a strong anti-steganalysis ability is achieved,with the steganography capacity greatly improved compared to the traditonal algorithms.
