Abstract
The present invention relates to a protection system for printed documents using steganographic and computer vision, materialized by the use of portable devices, where ETCODE encoded images are generated for this purpose. This method was created in order to ensure the document's authenticity, integrity of information, store information about authorship and copyright protection of printed documents. The protection method described in this patent is to generate an encoded image ETCODE using steganographic techniques, to be printed with the document, using conventional printers, and also that the decoding is performed by a digital camera portable device, obtaining therefore the information hidden in ETCODE, and then confronted with the information about the document in its digital version present in a database, thus fulfilling the proposal document protection.
