Information Hiding Based on LDPC Matrix and CS Technology
Tian Peng-y · Journal of Sichuan Ordnance · 2015
For compress sensing technology applied in the field of information hiding,the traditional algorithm was based on the Gauss random matrix as a measurement matrix,and the transparency of the carrier density information and computing time remains to be further improved,using LDPC matrix as a measurement matrix to calculate,we finished secret information hiding. And through the experimental simulation and data calculation,the method is superior to the traditional on imperceptibility and computing time loss,at the same time,it has a certain robustness of the algorithm.
