Complementary matrix–based algorithm for data hiding
SU Jin-hai · Journal of Communications · 2007
The complementary matrix–based algorithm for data hiding presented does a good job at capacity of data hid-ing and data security.The proposed algorithm can conceal as many as [lb2 n] bits data in n bits host data stream,by changing,averagely,[(3/ 2)?(1/ 2m ?1)] bits.There are so many kinds of complementary matrices,and the secret key is only shared by the sender and extractor,so the algorithm is very secure.
