一种具有纠错能力的半脆弱水印算法
A Semi-Fragile Watermarking Algorithm with Ability to Correct Mistakes
摘要
Abstract
Along with the rapid development of digital technology and internet,image data safety protection is getting more and mote serious and digital watermarking technology has become an effective way to protect the safety of the data. It proposes a blind semi-fragile watermarking algorithm based on Hamming code, which is used in image copyright protection. First of all,it transforms binary watermark signal to Hamming code and modulates it,then embeds the mcdulatec watermarking into the original image. This process uses adaptive partition algorithm. At last,it adopts the correcting algorithm of Hamming code to extract the watermark, which soives the contradiction between watermark invisibility and robustness felicitously. Experimental results show that this algorithm has a bit of toleration to attacks, such as JPEG lossy compression and Gaussian low-pass filter.关键词
