Abstract
Digital watermarking has been proposed as a solution to the problem of copyright protection of digital images in digital phone camera. There are two important issues that watermarking algorithms need to address. First, watermarking schemes are required to provide trustworthy evidence for protecting rightful ownership. Second, good watermarking schemes should satisfy the requirement of robustness and resist distortions due to common image manipulations. This paper presents a blind image watermarking scheme for camera phone. This method is based on singular value decomposition (SVD) and wavelet decomposition. Analysis and experimental results show that the proposed watermarking method performs well in security and robustness of digital phone camera.
