Wedi: method and system using symmetric or asymmetric encryption algorithms for the generation of cryptographic keys that enable the identification of printed documents and in the middle eletru00c8nico and accountability of persons for the dissemination and use of information. Contained in these documents, illegally, ilu00eccita allowed or not.The wedi, which is an acronym for (watermark encryption document ldentification), is a method and system that enables the identification of document and printed in electronics and information, through the generation and printing of a cryptographic key as a watermark.Generated by the application of algorithms cifradores symmetrical or asymmetrical hashing function from various data on the document itself, on devices and people involved in their generation, that enables the identification of these documents as to its origin, the destinatu00e1 The river, the date and time of your generation, the date of shipment to the consignee, the user responsible for generation.And other information about the document, from procurement of only part or pieces of those documents that contain fragments of the cryptographic key as a watermark printed.
