摘要
Abstract
In this paper,we proposed an attack-resistant lossless recovery visible watermarking algorithm which embeds colour watermark into source colour image.The algorithm embeds three components of watermarking image RGB into the corresponding colour components of the host images by modulation.In order to achieve lossless recovery,it takes the quantisation errors generated in embedding process as the recov-ery data,and embedded around the watermarking region based on the difference expansion lossless watermarking technology.All embedding processes are controlled by a secret key in order to increase the security of the watermarking.Simulation experiments show that the watermark transparency of the algorithm can modulate smoothly,the legal users can achieve lossless and reversible recovery,and for illegal users the al-gorithm has strong attack-resistance property.关键词
