Document Authentication Using Print-Scan Image Watermarking Based on DCT (Discrete Cosine Transform) Algorithm

The piracy of copyright issue has become very serio us problem to be dealt. Important printed documents such as certificates, i nsurance policy, and other important documents can be manipulated by someone according to the technology development. In this study, we propose a technique on document a uthentication using watermarking. The image which has a copyright sign (copyright image) is embedded to the cover image such as logo or any oth er image to be watermarked image, then the watermarked image will be embedded on document, the watermarked image will be extracted when the document will be authenticated. The method is based on DCT (Discrete Cosine Transform) algorithm.
