Description
Technical field
The present invention relates generally to a kind of method and system of differentiating product authenticity.The present invention has especially described a kind of utility system with unique processing process, and this system is easy to dispose, is easy to use and very effective and strong strike adulterator.
Background technology
Now, special in new superior technology, commodity are forged becomes a serious problem.The commodity of forging can seem true more and quantity huge.The adulterator has deprived the brand set up for many years of may needing of manufacturer.They with false, low-quality, sometimes in addition dangerous product (such as: medicine) rob the consumer.It is generally accepted that good Antiforge system can help manufacturer and consumer, and if manufacturer and consumer all participate in anti-pseudoprocess can be the most effective.
By the United States Patent (USP) 6,226,619 that is entitled as " the wholesale and false proof method and system of retail product of high price " of Halperin et al. application, disclose and used a kind of REIF label and label plug-in reader to make client can participate in anti-pseudoprocess.Existing method adopts a kind of RFID label that is attached on the product, the secret coding of label the inside is read or decrypted to the label plug-in reader, and the consumer can compare reading the result and being printed on sequence number on the product brand and confirming the authenticity of product of plug-in reader then.Yet several shortcomings is arranged in existing systems.At first, except RFID label and label plug-in reader, each product all needs unique sequence number, and for typical products in mass production, this causes manufacturer to be difficult to realize this system.The second, be that consumer rather than label plug-in reader are differentiated work really, they have to start and use eye relatively to read result and the number that is printed on the label.Consider a large amount of different types of commodity, this method is difficult to use for consumers, and the consumer may become at a loss as to what to do.The 3rd, prior art is mentioned but is not probed into the actual use of public key encryption, and public key encryption will be the core technology of Verification System, and prior art does not provide manufacturer how PKI to be distributed to consumer's solution when selling.Last but the most worth comment a bit be, security breaches are arranged in existing systems, the adulterator with modern technologies can make thrashing easily by duplicating particularly label plug-in reader of total system.
In addition, existing system is not easy to realize concerning manufacturer.A unique sequence number that is printed in the conventional method on the product brand is essential.For manufacturer, found and safeguard such coding system, when particularly carrying out a large amount of productions of product and in existing vendor system (such as drinks), not having the product rank to follow the tracks of, will become a big burden.This goes the very identical problem of the problem that solves-the avoided use of large database as possible with regard to having got back to existing method.
And existing system is not easy to use concerning the consumer.In existing system, the consumer must do a lot of work and differentiate a retail product voluntarily.They use the label plug-in reader to obtain reading the result, search correct trade mark in product, relatively read the sequence number of result and printing then.Because the trade mark or the sequence number of different vendor do not have standard format, when buying a new product, the consumer must heavily learn this process at every turn.Apparently, because the consumer might use wrong trade mark or wrong number, therefore this manually-operated process also has erroneous tendancy.
Although the use of existing system suggestion public key encryption should be advised only at data protection, rather than to its actual use-authentication.In fact, as long as text data (such as: manufacturer's name) can be proved to be creation, just needn't encrypt by manufacturer.In the existing system, the consumer by artificial treatment extra trade mark and sequence number realize certification work, rather than in label and label plug-in reader, use digital signature technology.Existing requirement does not design a kind of method of using existing system to distribute PKI to the consumer when selling for dealer.Do not have this important step, just can not use public key encryption in existing system.
Furtherly, existing system itself can be forged easily.Previous method looks to chip manufacturing proces itself to make in the label data not have reproducible.Public key encryption also is proposed to be used in data protection.Yet can crack system easily by the following steps adulterator, (1) printing one has the trade mark of sequence number then it to be positioned on the fake product, (2) with clear-text way identical number is write into label, then label is attached to fake product, (3) manufacturing one simple label plug-in reader is read the plaintext in the label.Obviously, not further protection, the Antiforge system of a forgery can be made easily together with fake product.With regard to current techniques, it is easy to do making " vacation " existing system.
Therefore, existing system exists some important disadvantages and problem.Manufacturer is difficult to realize that the consumer is difficult for using.Although public key encryption is referred, only is proposed to be used in data protection, rather than is used for real use-authentication itself.Unfortunately, the workload of authentication has been delivered to the consumer.Their certification work of being compelled to do is started and is used eye relatively to read some numbers on result and some trade marks.In addition, there is not solution how to be distributed to the consumer about PKI when selling.And, there is not other safeguard measure, be highly brittle weak and made it complete failure easily by forged trade mark, label and plug-in reader existing system.
Summary of the invention
In view of the shortcoming and the problem of prior art, an object of the present invention is to provide a kind of method for anti-counterfeit, system and processing procedure that is widely used in any product easily.

Embodiment
Now referring to Fig. 1, be the synoptic diagram of a comprehensive process of system of the present invention, system is made up of central authority (CA) website and internal database, RFID/ smart card label, RFID/ smart card label plug-in reader and a well-defined program.Participant in this process is the employee (a.k.a.CA) of manufacturer, consumer and CA, along with the step in this process has been implemented some innovative approach.There are three major functions CA website 1.10: be used as a private key storehouse, be used as one and be used for manufacturer registration and obtain themselves private key and the inlet of sell goods ID and be used as one being used for the inlet that the consumer verifies the label plug-in reader of its use.CA website 1.10 must be an authorized mechanism, and its url must be fully open and known for everyone.Internal database 1.13 is used for storing the log-on message of all data such as private key set and manufacturer.
RFID/ smart card label 1.11 is set in the protected commodity.Label is a kind of standard, commercial available, safe RFID/ smart card label, the signature that this label has enough internal memories to come a storage plant quotient data and a usefulness special format to write.Before allowing data access, this label can be safeguarded the authenticity of internal data and verification plug-in reader device.The method to set up of this label is the method for specifically label being destroyed or remaining valid after commodity use.Feature plug-in reader 1.12 is special arrangements, and this device has standard RFID/smart card label plug-in reader function to read and to decode from the data of the RFID/ smart card label 1.11 of the available safety of commerce.This label plug-in reader 1.12 is in the PKI storehouse of central store one preload (public key ring) and have the ability next from outside renewal public key ring.In addition, label plug-in reader 1.12 can obtain sell goods ID from label data, and uses ID to extract sellers' product PKI from public key ring.In addition, label plug-in reader 1.12 can use public-key and verify the digital signature that is built in the label data and display result on a LCD window.At last, if signature is effectively, label plug-in reader 1.12 can show that Business Name and name of product are at a small LCD window; Otherwise will show an alert message.In order to reach the purpose of self-correcting, in case the button of testing oneself is pressed, this device also can generate an one number based on other hiding parameter of it self sequence number and some.
Process steps 1.1 among Fig. 1, and CA employee uses standard cipher method to produce large quantities of public affairs/private keys to 1.9.Each private key and PKI 1.9 are set up index respectively, but by using identical number, this number will become sell goods ID when product of manufacturer's registration.Step 1.2 among Fig. 1, prefabricated private key set is stored in the CA database 1.13.Each private key is set up index by an one number, and this number will be assigned to a product as sell goods ID after a while.Step 1.3 among Fig. 1, prefabricated PKI set is used as public key ring and is loaded in the label plug-in reader device.Each PKI is set up index by a sell goods ID and is fetched, and this ID can read from RFID/ smart card label 1.11.Step 1.4 among Fig. 1, a manufacturer is by CA website 1.10 registration one products and obtain a unique sell goods ID and a private key.Step 1.5 among Fig. 1, manufacturer obtains commercial available safety label, the sell goods information that comprises sell goods ID that needs is written to this label, use private key this information of digitized signature and label is gone in the preservation of should signing, be provided with when needing this label 1.11 to product so that label destroyed or remained valid.Step 1.6 among Fig. 1 has a question or use for the first time, and the consumer can carry out an authenticity of testing oneself and in use verifying the label plug-in reader with 1.10 cooperations of CA website or by CA phone/wireless service at any time.The details of this technology will be described in detail in Fig. 5.Step 1.7 and step 1.8 among Fig. 1, this two step is to implement when selling and comprised the major part work in the process.The RFID/ smart card label 1.11 that the consumer uses the label plug-in reader to read to be set on the product and confirm the authenticity of product.
Fig. 2 has described cipher key management procedures in detail, and the operator is CA employee, and detailed process is key generation, management and distribution procedure.At first, shown in step 2.1, it is right that CA employee uses the cryptography method of standard to create large quantities of public affairs/private keys; Referring to step 2.2, key is criticized and is processed into two arrays of separating then, and one is used for PKI 2.3, and another is used for private key 2.4.These two key arrays use identical index number to set up index.When an index number is assigned to when having registered the manufacturer of a product by CA website 1.10, this number will become sell goods ID.In step 2.5, the PKI array (a.k.a. public key ring) of setting up index is preloaded in the label plug-in reader.This key ring can pass through an index number with each PKI, and promptly a described sell goods ID is stored in the plug-in reader device by the mode of unique identification and taking-up.In step 2.6, the private key array 2.4 of setting up index is stored in the CA site database 1.13, and this private key and sell goods ID will be distributed by the process of the registration of manufacturer in the CA website, and this will discuss hereinafter.
In a word, key of the present invention is to make in advance, and ID sets up index according to sell goods.PKI 2.3 is preloaded in the label plug-in reader device 1.12, and private key 2.4 is stored in the CA site databases 1.13.Private key is distributed to the manufacturer by 1.10 registrations of CA website.The manufacturer of one registration uses private key to sign to be stored in the data in the RFID/ smart card label, and also preserves digital signature and sell goods ID in label.PKI is distributed to the consumer immediately when selling, and comes when a RFID/ smart card label reads sell goods ID when a consumer uses a label plug-in reader, and this label plug-in reader uses sell goods ID to extract PKI successively, and therefore carries out verification process.
Among Fig. 3, a flow chart description manufacturer's whole process of how to make their antifalsification label, the operator is a manufacturer, detailed process is for making antifalsification label.In the first step 3.1, manufacturer must need the product of protection by 1.10 registrations of CA website.After necessary background was checked, in step 2 3.2, manufacturer was assigned to a unique sell goods ID and from the private key that before was stored in the private key array 2.4 in the CA database.For instance, manufacturer obtains 102 sell goods ID.As shown in Figure 2, corresponding public key has been stored in the label plug-in reader device 1.12, and can be extracted out by number 102 (2.3).In step 3 3.3, manufacturer is written to following information in the one commercial available RFID/ smart card label: (a) manufacturer, product related information, (b) sell goods ID (such as 102) and (c) digital signature, in step 4, this digital signature is produced by the signing messages in (a).The data layout that is used for label will be described in detail at next figure.In last step 3.5, manufacturer sets up label to need protection product.According to the person's character of product, this method to set up can be used the back at product and destroy label, perhaps is used the back at product and keeps label effective.
As shown in Figure 4, be the data layout of RFID/ smart card label.Definition has four necessary data fields in label.Sell goods ID 4.1 is used to extract the sell goods PKI from label plug-in reader device.In case digital signature 4.4 comes into force, trade name 4.2 and name of product 4.3 fields are used to the visible confirmation to the user.Optional Field 4.5 can be stored extra manufacturer/product or product specific information.
Fig. 5 is a RFID/ smart card label plug-in reader functional diagram, has described the major function that label plug-in reader 1.12 is carried out.One software program 5.5 is as a function control device.Step 5.1, label plug-in reader 1.12 are at first from a RFID label 1.11 sense datas.Step 5.2, program is resolved the data of input, obtains sell goods ID 4.1 from label data, and uses its public key ring 5.6 extraction product PKIs internally.Step 5.3, program is resolved the input data and is extracted signature, and the operation cryptographic algorithm uses public-key certifying signature.Step 5.4, if signature is effectively, program goes out Business Name and name of product from the data extract of input, shows them at LCD window 5.7.Otherwise program only simply shows an alert message at LCD window 5.7.
Fig. 6 is the RFID/ smart card label plug-in reader functional diagram that utilizes radio communication, for example understands another embodiment that is incorporated into the label plug-in reader 1.12 in a PDA or the portable telephone device, thereby has off-the-shelf available wireless connections.By ready available wireless connections, public key ring can be stored in the CA website 1.10 when selling.After step 6.1 obtained sell goods ID 4.1, a software program 6.5 only needed to set up wireless connections and extracts PKI from outside CA website 1.10, shown in step 6.2.A very important aspect of the present invention provides the complete solution of a discrimination process, comprises the discriminating of label plug-in reader itself.As what point out previously, be not used in another checking measure of label plug-in reader itself, whole retail product standard authentication system can be become useless easily by a comparatively astute adulterator with some advanced technologies.For example, the plug-in reader by making a personation and distribute themselves personation label together with the personation retail product, the adulterator can create a system of forging fully and cheat the consumer.Fig. 7 is a RFID/ smart card label plug-in reader proof procedure, describes the authentication of label plug-in reader in detail and how to carry out.One label plug-in reader device 1.12 has the button 7.6 of testing oneself and makes.One unique sequence number 7.5 also is engraved on the lid of device.Central authority (CA) be provided for verifying plug-in reader based on website or based on phone/wireless interface 1.10.Feel uncertain when producing, the consumer is connected with the service for checking credentials of CA label plug-in reader, at first submits device sequence number 7.5 in step 7.1, then by pressing " testing oneself " button 7.6 operating procedures 7.2 on device 1.12.This device responds with a number that is presented at LCD window 7.7.This number is to use device sequence number and other parameters by the unique generation of internal processes.In step 7.3, the user submits to the number of generation to be used for checking to CA service 1.10.In step 7.4, the CA service 1.10 operations algorithm identical with actual device generates a number and compares two numbers that generate for the checking purpose.This checking result returns to the user.In case this label plug-in reader device is effectively and can be trusted, the user can use this device to carry out authentication tasks having on all types retail product of RFID label 1.11 repeatedly, is used for false proof whole Verification System and is safety and effectively.
Fig. 8 has exemplified the sample design of a RFID label by Figure 10 and has been used for the method to set up of liquid bottled product.As shown in Figure 8, for being used for the RFID label of liquid bottles, the RFID label is formed on the thin plastic-substrates 8.1 of a rectangle; Form by the antenna loop 8.2 and the commercial RFID label chip 8.3 that receive the RF signal.Two short and small otch 8.4 are formed in each limit of label, so that the easier jackknifing of label when being twisted by uncork.Fig. 9 is arranged on liquid bottles for the RFID label as strip of paper used for sealing, described RFID label 9.2 by sticker on a liquid bottles 9.4 and break otch 9.3 and bottle cap 9.1 bottoms in a straight line.To open the back label destroyed for liquid bottles for Figure 10, described when bottle is opened this RFID label and how to have been destroyed.Shown in step 10.1, bottle cap 9.1 is reversed opens bottle 9.4, and it causes the top rotation of label 9.2 successively, breaks along the otch that breaks then.This breakage has also destroyed antenna, therefore makes that the RFID label is invalid.
Though the present invention uses above-mentioned specific embodiment to describe, it is intelligible that a lot of replacements, modification and variation are obviously arranged to those skilled in the art.Therefore, foregoing preferred embodiment of the present invention is only unrestricted in order to explanation, can make various changes and does not break away from the defined spirit and scope of claims of the present invention.
