It's a challenge to identify whether the paper archive is credible when it is printed out by the credible electronic archives system. First, this paper improves a DCT-based binary image digital watermarking algorithm. The universal algorithm not only applies to text, but also other binary image. It's so robust that can withstand more than three times attack of paper print-scans; the image is modified with good visual effects; watermark extraction does not require the original document. Based upon the algorithm, this paper designs and implements a creditability validation system for paper document.
