A Simple and Efficient Removable Visible Watermarking Algorithm

摘要：

This paper proposes a novel and simple reversible visible watermarking algorithm based on lifting-based wavelet transform(LBWT) to satisfy a new application scenario where the visible watermark servers as a tag or ownership identifier, but can be completely removed at the receiver end to resume the original image.For our removable visible watermarking algorithm, we compute composite coefficients using random coefficients matrix in the LBWT domain.The visible watermark is securely embedded based on a user key controlled embedding mechanism.With correct user keys, authorized user can completely removed the watermark and lossless recover the original image.In contrast, unauthorized operations either overly or insufficiently remove the watermark due to wrong estimation of embedding parameters, and thus, the resulting image has apparent defect
