Method for processing random figure code

Abstract

The invention relates to a method for processing a random figure code, belonging to message processing fields. The method comprises the following steps: the generation method of the random figure, the generation method of the random figure code and the identification method of the random figure code. The method is characterized in that: a random image is generated into the digital random figure code using a feature that the random image cannot be duplicated and the random figure code can be used for realizing digital printing medium anti-counterfeit so as to solve a problem that a traditional analogue anti-counterfeit has a threshold value, be capable of drastically avoiding illegal acts such as merchandise fraud, paper currency fraud or stamp fraud, and the like, crack down on crimes that illegal persons withdraw cash with devices such as ATM, and the like, and lead the ATM to have a function for automatically identifying the forged paper currency.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for processing random graphic codes. Background technique [0002] With the rapid development of computer information network technology, the demand for certificates and seal authentication has become increasingly urgent. Especially in recent years, incidents of counterfeiting banknotes at home and abroad have occurred from time to time, which has brought serious threats to social stability. One of the main technical reasons for this phenomenon is that the reading accuracy of the image scanning device composed of optical coupling devices is greater than the printing accuracy of the printing machine, so that no matter what kind of printing machine is used, the image printed on the paper can be very realistic Scanned out, criminals can easily engage in counterfeiting activities, so this serious disruption of financial order, endangering social security and stability h...

Problems solved by technology

It cannot solve the problem of changes in transmittance caused by paper pollution, oldness, etc.

In addition, this method also provides an identification method similar to fingerprints, that is, the result of identifying paper fingerprints by calculating the intersection position of plant fibers. Because paper fingerprints do not have clear lines like fingerprints, it is difficult to apply in practice.

Furthermore, this technical solution avoids the problem of how to construct the paper fingerprints made of plant fibers into computer codes. It needs to be compared with the original preserved paper fingerprint images during identification. Therefore, this technical solution is the same as the technology disclosed in the previous patent. The scheme is the same, and cannot be applied to the authenticity identification of unspecific paper media such as product labels or banknotes
