Embodiment Construction

[0023] Now take the anti-counterfeiting of bank draft as an example to illustrate the process of the present invention.

[0024] combine figure 1 , figure 2 , image 3 , Figure 4 , The hardware of the ticket anti-counterfeiting system includes three parts: scanner, computer and printer. The color scanner is used to input the ticket image, and its resolution is required to be no lower than 200DPI, and a color camera with the same resolution can also be used instead of the color scanner. The computer is an ordinary PC, which is used for image processing and analysis during the ticket encryption process, and completes the extraction of ticket color identification fiber information and content information from the ticket image to form ticket fingerprints; It can interpret the dimensional barcode and verify the color identification fiber information and content information of the ticket image, so as to determine whether the ticket has been forged or altered, and the computer ...

Abstract

This invention relates to a certificate encipher and verify method based on identification fibre random distribution composed of certificate encipher and verify. An operator signs and a certificate with color identify fibre and fills in the content to scan with a color picture collection device. A computer extracts its inherent feature and the content feature to combine them to fingerprint and code to be converted to two-dimension bar code printed at a place of the certificate to be scanned to the two dimention bar code decoded. According to decodes information, the computer verifies its inherent and content features to justify and analyse contents of fake or altered certificates to report the judgment.

Description

1. Technical field: [0001] The invention relates to a ticket encryption and anti-counterfeiting method, in particular to a ticket encryption and verification method based on random distribution of identification fibers. 2. Background technology [0002] Various instruments (such as checks, money orders, promissory notes, banknotes, stocks, tax invoices, customs declarations, savings certificates, etc.) and documents (such as ID cards, work permits, military officer certificates, graduation certificates, passports, etc.) These tickets are widely used in our country and all over the world. Due to the important role of such tickets in the field of economic and social life, the criminal activities of counterfeiting tickets for various frauds have always existed and intensified, and have become a major hidden danger to national financial security and social stability. Therefore, ticket anti-counterfeiting has become a major economic and social issue at present. benefit research ...
