Digital watermarking algorithm for PDF document

Abstract

Abstract: Targeted at structural features of PDF documents, a new text digital watermarking algorithm is presented. According to itself syntax and structure of binary PDF file, the watermark is embedded without changing the original any visible attributes. Experimental results show that the digital watermark embedding method has good imperceptibility, and can effectively achieve document content integrity and copyright protection.
