Summary of the invention

The object of this invention is to provide a kind of label anti-counterfeit method with better antifalse effect, this label anti-counterfeit method fully merges scraping code, Quick Response Code and the technology process based on ID authentication, usually says that ID authentication technology is that the basis realizing mark safety management is also embodied thus.

Basic realization of the present invention is a thing one yard, and the method step of realization is as follows:

1. when Commercial goods labels generates, by the unique encodings of Practical computer teaching commodity, unique encodings need follow relevant coding rule, and coding can be domestic commodity code, can be international conventional commodity code, the standard also can encoded by enterprise's designed, designed;

2. in the coding standard of enterprise's establishment, part master data is designed to set form, a part is by the product ID of Practical computer teaching, product ID can not form by plain mode, in order to avoid copy generation easily after found rule, good method is that setting one section is encoded to random number, and random number copy-resistant ability is strong, and for doing, mark confidentiality is better.If the mark as commodity is chosen all, coding data are oversize, then can use as the mark of commodity by selected part coding, the code segment as commodity sign can select sequence number, selects random number to be good selections as the mark of commodity;

3. when selected mark being used for the generation of Quick Response Code, adopt and sign based on the technology of ID authentication, be specially and the character string as mark is carried out hash process, obtain the cryptographic hash of fixed length, then by cryptographic hash stored in Quick Response Code, out of Memory simultaneously stored in commodity in Quick Response Code, out of Memory is also through encryption;

4. scrape code to form as the data of commodity sign and the knifing covered in data by selecting, using as the data printing of commodity sign near Quick Response Code, data are covered to become with knifing and scrape code;

5. the selected data as commodity sign can adopt string number, also can adopt a string character, can also adopt one-dimensional bar code even another Quick Response Code;

6. time by the true and false of tag authentication commodity, need to use fetch equipment, available Quick Response Code scanner, data terminal or smart mobile phone are to Quick Response Code and scrape code and read, and the special fetch program should in advance stored in fetch equipment.First the identification data that knifing that open covering scrapes code obtains commodity is scraped, the numeric string that manual or scanning t test identifies or character string, hash process is carried out by the special fetch program, obtain the cryptographic hash of fixed length, utilize barcode scanner, the special fetch program of data terminal or smart mobile phone reads Quick Response Code, read after the cryptographic hash stored in Quick Response Code and it is contrasted with from scraping the cryptographic hash that code obtains, as identical in cryptographic hash contrast, prove that the label of business is not changed or replaces, as not identical in cryptographic hash contrast, illustrate that the label of commodity is changed or replaced,

7. this should in conjunction with closely by Quick Response Code and the Commercial goods labels scraping code combination and commodity, realize mark and commodity bind, this method as the powerful of commercial articles true and false discriminating, and can possess certain copy-resistant ability;

8. the Quick Response Code adopted as Commercial goods labels can select dissimilar Quick Response Code, and QR Quick Response Code, the Chinese can be selected to believe Quick Response Code, GM Quick Response Code, DM Quick Response Code, PDF417 Quick Response Code etc.;

9. as Commercial goods labels adopt Quick Response Code its write information except for contrast scrape code identify cryptographic hash except, also comprise the information of the necessity such as the name of an article of commodity, model, specification, time, and the leading address that merchandise query is reviewed, these information are through encryption, only having just can through deciphering display after cryptographic hash contrast is correct, cryptographic hash is to such as incorrect, and display discriminating is false and alarm by fetch equipment, can not decipher the information of display of commodity.

Conventional Quick Response Code can identify and arranges in pairs or groups from different code of scraping, and following examples are three kinds of array modes, and practical application can have more array modes.
