Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] like Figure 1 to Figure 4 as shown in:

[0049] A method for printing commodity information described in an embodiment of the present invention includes the following steps:

[0050] Step A1. Encrypt and divide the product information to form uniquely corresponding two and a half codes;

[0051] Step A2. Store one half-code in the database, and print the other half-code on the label as anti-counterfeiting information. At the same time, use a one-way function to calculate the offer value of the product information and then write it as a one-dimensional code (such as a barcode) or a two-dim...

Abstract

The invention relates to a printing inspection method and device for commodity information. The method includes: first encrypting and dividing the commodity information to form two uniquely corresponding half-codes; then storing one half-code in a database, and the other half-code It is printed on the label as anti-counterfeiting information, and at the same time, the product information is printed on the product as a mark after calculating the offer value of the product information using a one-way function; Included product information half code and product information offer value; finally, the extracted product information half code is synthesized with the unique corresponding half code in the database, and the product information and product information offer value are calculated, and compared with the extracted product information offer value , in order to realize the inspection of product information. It can not only effectively inspect the product information, but also greatly improve the security of the product information of the inspected product, and the anti-counterfeiting effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of commodity information anti-counterfeiting, and relates to a printing inspection method and device for commodity information. Background technique [0002] The anti-counterfeiting of printed matter, taking banknotes as an example, embodies the highest level of anti-counterfeiting technology in the country. [0003] For example: miniature text, special ink / invisible ink, watermark, hologram, etc. For example, watermarking, the technology of changing the thickness of the paper when filtering paper to embed the pattern, through the light from the back, you can confirm the appearance of the embedded watermark. Special inks can be used to observe different colors from different angles, or the appearance can only be seen from one angle, use special luminous ink, or make the appearance glow after being irradiated with ultraviolet rays. Hologram is a laser that irradiates the interference pattern onto the film t...
