Anti-counterfeit characteristic generation method of valuable file and identification method and device thereof

Abstract

The invention relates to an anti-counterfeit characteristic generation method of a valuable file. The anti-counterfeit characteristic generation method of the valuable file utilizes anti-counterfeit characteristic information redundancy to hide accurate anti-counterfeit characteristic information. In the processing mode, people perception detects almost no change of the anti-counterfeit characteristics of the valuable file, however, an valuable file identification device of financial self-service equipment is capable of extracting the hidden accurate anti-counterfeit characteristic information from signals obtained by a sensor effectively, and implementing quantitative detection and identification, and therefore the authenticity of the valuable file is effectively identified. In other words, due to the fact that the novel anti-counterfeit characteristic capable of being identified by a machine conveniently is loaded on the valuable file and the financial self-service equipment is provided with a corresponding valuable file identification device, the financial self-service equipment is enabled to read the anti-counterfeit characteristic capable of being identified by the machine of the valuable file, and identification accuracy of financial self-service equipment for the valuable file is improved. The invention further provides an identification method of the valuable file.

Description

technical field [0001] The invention relates to the anti-counterfeit technology of the valuable document, in particular to the generation of the anti-counterfeit feature of the valuable document and the identification method and identification device of the valuable document. Background technique [0002] With the rapid development of the social economy, the circulation of currency issuance has increased sharply, and the demand for automatic currency processing equipment has increased dramatically. Automatic currency processing equipment is used in banks, currency clearing centers, currency escort agencies, supermarkets, large gas stations, It is widely used in fields and industries such as retail shopping centers. [0003] However, the anti-counterfeiting features of valuable documents such as banknotes are mainly designed from the perspective of making things convenient for people to distinguish and identify. For example, banknote anti-counterfeiting features are designed...

AI Technical Summary

Problems solved by technology

However, in the anti-counterfeiting design scheme of most banknotes, the problem of how to make it easy for machines to read the anti-counterfeiting features of banknotes is not considered.

[0004] From the point of view of signal processing, the existing methods of identifying and authenticating valuable documents based on human perception only use the part of the signal that people can perceive, and the content used only occupies a small part of the entire signal. part, most of the remaining signal content is ignored as "redundant"

At the same time, because the banknote anti-counterfeiting feature is not specially designed for machine reading, when the valuable document identification system in the currency automatic processing equipment is identifying the real attributes of the banknote, the currency self-service processing equipment sensor scans the valuable document to be identified. Only information that can be used to identify valuable documents. For example, when an optical sensor scans the denomination number of the denomination ink on a 100-yuan banknote of a certain currency, the image data acquired by the sensor cannot reflect the denomination characteristics of the denomination number of the denomination ink This anti-counterfeiting feature, so the processing of the denomination number of the denomination ink on the 100 yuan banknote of this currency only stays at the level of identification, and cannot achieve the effect of authenticating counterfeit

[0005] With the continuous improvement of the technology of criminals making counterfeit banknotes, spliced ​​banknotes and coinage have reached a very high degree of simulation, and even reached the level of "disgusting the real ones". This has led to the proliferation of counterfeit banknotes in society and brought huge challenges to the automatic currency processing industry. , affecting the economic order of society and seriously threatening national financial security

If the anti-counterfeiting features of banknotes cannot be effectively used by machines, and the anti-counterfeiting features of banknotes only stay at the identification level and cannot be accurately authenticated, the existing financial self-service equipment will be very passive for all kinds of counterfeit banknotes. Order and social harmony and stability are bound to face severe challenges

[0006] The existing banknote identification technology has the following defects: the financial self-service equipment cannot read the essential anti-counterfeiting characteristics of the anti-counterfeiting features on the banknote, and does not make full use of the banknote identification information, so the ability to identify counterfeit is insufficient
