Abstract

A method about embedding watermark in PDF document is proposed in this paper. First, PDF document is converted into a image format. Watermark image is converted into a scrambling image by Arnold transformation.And then the watermark is embedded into the PDF document image by discrete wavelet transform for PDF document image and matrix singular value decomposition for watermark image. Not only can watermark be extracted without the original image, but also increase the safety by this means. Experiment express, on the condition that the same size of the watermark image,the method made more copyright information as watermark be embedded into PDF document and the amount of the watermarked PDF document data be affected less with the increase of copyright information.
