Study of Digital Image Watermarking Technique Based on QC-LDPC Code

WANG Min(School of Computer Science and Information Technology,Yunnan Nornal University,Kunming 650092,China)  
In this paper,an algorithm of digital image watermark based on wavelet and QC-LDPC code is introduced.This algorithm applies error correction based on QC-LDPC code in watermarking.The watermark is LDPC coded and embedded into the host image,then retrieved from the watermarked image using LDPC iterative methods.The results demonstrate that the proposed algorithm can enhance robustness and security.
