Current; both at home and abroad manufacturer is for the commodity of protection oneself are forged, and avoids and reduces economic loss, adopted various high-tech anti-counterfeiting technology means; as: false proof etc. based on digital watermark and laser technology; drop into huge, but the infringement that still can not stop counterfeit or inferior quality goods, the anti-counterfeiting technology that mainly is based on figure is high again; also can prevent making; as: the false proof of dollar adopted multiple hi-tech means in the world, yet false dollar of circulation still arranged on the market, and high chi evil spirit in road is high one zhang just for this.Along with networks development, the anti-fake certificate that utilizes network to carry out commodity has begun in various countries to rise, but, the false proof method of this class is based on " static state " authentication code relatively, promptly has security code in producer's network WEB server, compares the method that realizes commodity counterfeit prevention with the interim security code of importing of user, the main leak of this method is, false proof person or hacker can usurp or distort the parameters for authentication in manufacturer data storehouse by network, so counterfeit or inferior quality goods still can not effectively be prevented and treated.

Summary of the invention:

The present invention uses the symmetric cryptography encryption technology to realize the false proof of commodity, is utilization computing machine, network and cryptographic algorithm technology make up a commodity counterfeit prevention authentication on network platform, and the user can carry out the anti-fake certificate of commodity in real time by this authentication platform.The Verification System all processes realizes that with soft, combination of hardware mode or with the pure software mode specific implementation method is as follows:

1, the commodity of every kind of producer model are all set up a commodity certificate, encrypt the security code that the commodity certificate obtains commodity with symmetric cryptographic algorithm, the length of security code is: K, K=10～50 bit digital, the factory number of security code and commodity is corresponding one by one, and the length of the factory number of commodity is: L, and L=8～18 bit digital are formed, the factory number front portion of commodity is divided into the marque code, and the rear portion is divided into the production quantity numbering of commodity.Before every commodity dispatch from the factory, in its trade mark or external packing, printing the anti-fake certificate parameter of network address, phone and these commodity of manufacturer, parameters for authentication comprises: the factory number of commodity and security code, wherein security code is coated with dark coating, scratch when the user authenticates and open, the user can carry out anti-fake certificate to commodity by the input authentication parameter.

2, the user is after the input authentication parameter, whether the WEB server at first compares the factory number of commodity correct, if numbering mistake, then be counterfeit or inferior quality goods, if numbering is correct, then choose parameter promptly according to the key of the factory number correspondence of commodity: timestamp and random code are selected key, and, select the commodity certificate that server end is retained according to the factory number of commodity again with in its input cryptographic algorithm, encrypt the commodity certificate with cryptographic algorithm and obtain security code, at last, the commodity counterfeit prevention sign indicating number that this commodity counterfeit prevention sign indicating number and user are sent compares, if the security code difference, authentication result is counterfeit or inferior quality goods, if security code is identical, authentication result is a certified products.

3, use combined type key generation method promptly: combination is selected the N group and is merged generation one group key at random from M group " sub-key ", wherein: M=510～2210, N=8～16, choose by timestamp and random code control, do not reuse with the key that guarantees symmetric cryptography, accomplish one-time pad, also save the loaded down with trivial details work of regular key updating and management simultaneously.

4, producer must set up commodity counterfeit prevention code data storehouse, comprising: contents such as commodity factory number, security code, timestamp and random code, and this database function is:

(1) is commodity authentication registration parameter, set up the parameters for authentication database with the partial content in the commodity counterfeit prevention code data storehouse, comprise: contents such as commodity factory number and security code, before commodity dispatch from the factory, in the trade mark that the telephone number and the network address of commodity factory number and security code and producer is imprinted on commodity in the lump or the external packing of commodity;

(2) verification process for system provides verify data, set up the false-proof authentication system database with the partial content in the commodity counterfeit prevention code data storehouse, comprise: contents such as commodity factory number, timestamp and random code, carry out commodity when authentication the user, for the encryption system of WEB server end is correctly chosen key and the commodity certificate provides parameter.

5, the commodity certificate of cryptographic algorithm, key and various model commodity is left in the safety box in the server, and with the factory number of commodity, the parameter that control key is chosen: timestamp and random code leave in the data in server storehouse.

6, in the network WEB server of producer, set up the authentication monitor database, the user is carried out the overall process of commodity counterfeit prevention authentication and monitor data such as the time of registered user's identification of commodities, commodity factory number, user's network address or phone in real time.Analyze by statistics, lock the commodity that those were authenticated factory number repeatedly, with it as being monitored by the emphasis object of suspicion, for producer provides may be by the factory number inventory of " clone " commodity.

7, producer sets up the merchandise sales archives, and when producer gave businessman with merchandise sales, the factory number of registering these commodity was as archives.The commodity of some numbering that emphasis is suspected are reported to the administration for industry and commerce, or are found out the fake producer in conjunction with the advertising campaign with lottery of producer by consumer's participation.
