- Script format document authentication scheme based on watermarking techniques M. González-Lee M. Nakano-Miyatake H. Pérez-Mean G. Sánchez-Pérez Ingeniería Digital watermarking Document FIle format Script format document Document authentication In almost all watermarking-based document authentication systems, the documents are considered as binary images and then, the watermark is embedded using some image watermarking algorithm. However actually important documents are saved using document le formats, such as Portable Document Format (PDF) or Open Document Format (ODF), among others, because in general the le size is smaller compared with an image le, and also these are considered as more secure than other types of le format. However, the documents with these formats can also be maliciously modified for illegal purposes, making necessary the development of mechanisms that are able to detect such modifications. Considering the situations mentioned above, this paper proposes a document authentication scheme in which a watermark is directly embedded into the document file format as part of the document itself. The experimental results show a desirable performance of the proposed algorithm.
