Abstract

After analyzing the PDF file and PS file, a novel information-hiding algorithm based on the Page Object of PDF file is proposed. First, a piece of PS code will be finished in PS file to create a new Page Object of PDF, and then the secret information is camouflaged to form the attribute value of the new object. The embedding and extracting of information in PDF document have been implemented. Theoretical analysis and experimental results show that this algorithm does not affect the output of the readers, the editors and the printers, and capacity and robustness are superior to other similar methods.
