APPLYING WATERMARKING IN DIGITAL IMAGE COPYRIGHT PROTECTION
Nowadays, with the rapid development of the Internet, the transmission of digital data such as images, videos and texts through the Internet becomes more convenient. Therefore, how to protect the integrity and copyright of digital data has become an urgent issue. This paper presents a watermarking method that based on Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) in order to protect copyright of digital images. The experimental results show that the quality of watermarked images are maintained good with high robustness against various attacks and watermark can be extracted from embedded image without original image.
