Quick Response Code has following feature: 1, high density coding, and information capacity is large: can outfit as many as 1850 capitalizations or 2710 numerals or 1108 bytes, or more than 500 Chinese character, about higher than common bar code information capacity tens times.2, coding range is wide, picture, sound, word, signature, fingerprint etc. digitized information can be encoded, show by bar code; The program be programmed in wherein can be run.3, fault-tolerant ability is strong, has error correction: this make two-dimensional bar code because of perforation, stained etc. cause local damage time, can correctly be distinguished, damaged area reaches 50% still can recover information in the same old way.4, reliability of decode is high, and it is more much lower than common bar code decoding error rate 2/1000000ths, and the bit error rate is no more than 1/10000000th.5, can introduce encryption measures, confidentiality, antifalsification are good.6, cost is low, easily makes, durable.7, bar code symbol shape, size variable-scale.8, two-dimensional bar code can use laser or the recognition of CCD reader.
In prior art, a lot of product uses Quick Response Code to carry out the false proof of product, the essential informations such as the producer of product, the place of production, network address, article No. are normally compiled in Quick Response Code by this method for anti-counterfeit, for scanning input identification, realize antiforge function.Because this Quick Response Code be printed on product is general on a collection of product, unique correspondence of product is realized by means of only the article No. of product or numbering, as long as fake producer just can read the essential information in Quick Response Code with common Quick Response Code recognizer, again arbitrary article No. or numbering are compiled in the essential information of product, just can forge and sell user and differentiate unclear true and false Quick Response Code, the Quick Response Code of this imitation is printed on product, user differentiates unclear true and false after identification Quick Response Code, and its antiforge function is poor.
Summary of the invention
The present invention is directed in prior art, the two-dimension code anti-counterfeit function be printed on product is poor, and the information in Quick Response Code is easily copied, and user is difficult to the problem of point evident, provides a kind of antifake method for products based on Quick Response Code, improves the antiforge function of Quick Response Code.
Technical scheme of the present invention is: a kind of antifake method for products based on Quick Response Code, mainly comprises the following steps:
The generation of A, two-dimension code pattern and printing
Set up a product coding database;
Extract product coding at random in product coding database, product coding compiling is converted to the character string of product, form the string data storehouse of product;
Extract the raw information of product;
The random character string extracting a product from string data storehouse again, a character string is only extracted once;
The character string EK encryption key of the raw information of product and extraction is carried out ECC cryptographic calculation, obtains a random enciphered data;
This enciphered data is encoded, generates the two-dimension code pattern of a product;
The two-dimension code pattern of product coding and product is printed on a product respectively;
B, Product Validation
Read with identification equipment and be printed on two-dimension code pattern on product;
This two-dimension code pattern is decoded, obtains the enciphered data of product information and the character string of carrying in two-dimension code pattern;
ECC decrypt operation is carried out to this enciphered data DK decruption key, obtains the information of product and the character string of product;
First time judgement is carried out to the true and false of product: whether the product information that contrast two-dimension code pattern is carried is consistent with the raw information of product, and information is unanimously true;
Carry out second time to the true and false of product to judge: first time is judged as genuine product, again from the product character string that Product Validation entrance input two-dimension code pattern is carried, proving program carries out decompiling to character string, obtain product coding, whether unanimously with the product coding be printed on product check this product coding, coding is unanimously true.
Adopt the technical program, form character string after being compiled by the coding of product, then the raw informations such as the producer of product, address, network address are encrypted compiling together with character string, form the Quick Response Code of product, be printed on product, on product, independent printing does not add the coding of the product of compiling; User is when buying commodity, by scanning product Quick Response Code, obtain the character string of product, this character string is input in the website that producer provides, after carrying out automatic decompiling decoding, obtain the product coding of character string representative, when this coding is identical with the coding be printed on product, judge that this product is true.
Because the coding of product forms character string after the compiling of producer, the compiling of producer to this character string is encrypted, adulterator is difficult to decode character string, thus be difficult to accomplish the corresponding of character string and product coding, user is by upper producer website, identification string information, accurately can judge authenticity of products.
