Method for processing information embedded in electronic file

Abstract

The invention relates to a method for generating micro-codes, which is applicable to information embedded in an electronic file like PDF and the like and belongs to the field of information processing, and the method comprises the following specific processing steps: reading a document file which is represented in the form of an image and reading time authority representing the file, reading and modifying the authority, information safety management including file process management information and the like or additional information including file all content information; converting the additional information to codes in the form of micro-codes, and embedding the codes in the form of the micro-codes into the image; and outputting an image file. The method can realize the unification of electronic documents and printed documents and the integration of document notes and the information, carry out safety management on the documents, prevent the document notes from being falsified and form an automatic reading system of the document notes. The method is characterized by low introduction cost and convenient popularization.

Description

Technical field [0001] The invention belongs to a processing method for embedding information in an electronic file in the field of wireless communication. Background technique [0002] According to the statistics of the International Telecommunications Union (ITU), as of the end of 2008, the total number of mobile phone users in China, India and the United States alone exceeded one billion. The number of mobile phones produced has been rising sharply, so the value-added service business of mobile phones is also a hot spot. An important technical means to expand mobile phone value-added services here is to solve the problem of mobile phone network access, that is, how to simply connect the mobile phone directly to the network. [0003] To solve the problem of mobile phone network access, as early as 2000, Japan had a patent application entitled "Provide information service (information provision サ一ビス)" (Patent Document 1), and proposed to use the camera function of the mobile phon...

Problems solved by technology

[0008] However, according to such a scheme, the two-dimensional barcode for taking pictures of mobile phones cannot be put together with ordinary mobile phone camera functions, thereby increasing the production cost of mobile phones and affecting the popularization of mobile phone taking pictures and surfing the Internet. In addition, printing trademarks with special ink, It also causes an increase in printing costs, and the result is not conducive to the popularization of this technology.
