A Printed Document Having Function Of Preventing From Forging/Manipulating The Method Thereof and The Inspecting Method Of The Printed Document

摘要

the present invention is a document printing device identification code information, hash algorithm, code generation features having the document creating device, it is connected to the document creating apparatus is printed in the document through the document printing system of the printing apparatus the document is printed; It made of a phase that is a hash value generated by the hash algorithm from the document information and document printing device identification code information (hash value generation step), a step in which the code is generated from the hash value (code generation step), a document printing code generation is code generated in operation of the forgery preventing method of the document, characterized in that printed on the article and the forgery prevention function is provided article. ;
