A method for generating and identifying protective documents and an information management system

Abstract

The invention provides a method for generating and identifying protective documents and an information management system, including obtaining the document to be protected in electronic format; determining the foreground image of the document based on the document to be protected, and calculating the document to be protected in electronic format MD5 value, convert the MD5 value to the background image, and obtain the pixel information of the foreground image and the background image respectively; based on the CMYK printing color mode, the pixels of the foreground image and the background image are superimposed to generate a logo image, using CMY synthetic color and The K color represents the pixel of the logo image; use the printing device to output the document with the logo image. By hiding the background image in the foreground image, the anti-counterfeiting mark is hidden. Based on this technology, the application and identification of document anti-counterfeiting can be realized, and the closed loop of official document generation and use can be realized, so as to avoid the situation that the document is forged and tampered and cannot be identified.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting, in particular to a generation and identification method and an information management system for protective documents. Background technique [0002] In the information age, the conventional methods of identifying the authenticity of documents mainly include the seal of the document issuing institution, and the watermark made by editing tools such as WORD on the printout. At present, due to the popularization of computer technology, PS seals are no longer difficult, and the use of document editing tools to make watermarks has become a necessary skill for secretaries; The issuing party and the related parties are not under the same system, so that the user cannot easily verify and identify the authenticity and validity of the document by using other methods other than conventional methods. Therefore, the above situation objectively creates opportunities and loopholes for illegal or eve...

AI Technical Summary

Problems solved by technology

At present, due to the popularization of computer technology, it is not difficult to use PS stamps. Making watermarks with document editing tools has become an essential skill for secretaries; The issuing party and the related parties are not in the same system, which makes it impossible for the user to conveniently verify and identify the authenticity and validity of the document by using other methods other than conventional methods

Therefore, the above situation objectively creates opportunities and loopholes for illegal or even illegal use of documents, which can easily lead to inaccurate information, misjudgment and economic disputes

[0003] For example, the content of the document may be tampered with due to profit-driven, so as to better meet the interests of a certain party; The use of functional documents brings risks to users, etc.
