Summary: | 碩士 === 國立高雄應用科技大學 === 電子與資訊工程研究所碩士班 === 95 === Thesis proposed a novel CDMA technique for multiple watermarking applied on digital images. Because the owner of the digital image can apply his private modulation code sequence to embed his watermark into an image, regardless of any others, each user can independently retrieve his watermark from the watermarked image as his secret code (private modulation code sequence) is given. The experimental results show the proposed method is reliable enough protect against the JPEG compression and cropping.
