Description
Technical field
The invention belongs to the applied technical field of mobile communication, relate to the identity identifying technology in communication network and the computer system, be a kind ofly to utilize dynamic sign indicating number to carry out the false proof method and system of mobile phone, can help the consumer when buying mobile phone, to discern the true and false of mobile phone at the scene effectively.
Background technology
Along with developing rapidly of mobile communication technology, cellphone subscriber's quantity is also in quick growth, little by little become one of instrument indispensable in people's daily life and the work as the mobile phone of one of informationized society sign.The importance of mobile phone in people's daily life is self-evident, but because legal system is still unsound, market is lack of standardization, and some lawless persons are in order to seek exorbitant profit counterfeit mobile phone both at home and abroad, adulterate, mix the spurious with the genuine, formed certain personation mobile phone market, the height of the output value of the annual mobile phone of being palmed off on the mobile phone market, seriously upset social economic order, damaged mobile phone manufacturer and consumer's interests.In recent years, mobile phone manufacturer and consumers in general with the struggle of fake and forged mobile phone in sense of self-protection strengthen gradually, how to carry out the false proof of mobile phone and how to forbid the focus that the circulation of fake and forged mobile phone has become mobile phone manufacturer and consumer to pay close attention to.
Be that at present, general mobile phone anti-counterfeiting technology is verification hand-set host fuselage number (ESN of the IMEI number of GSM mobile handset and CDMA mobile phone number) and a Marks of Network-entry License described in the patent documentation of CN1581189A as publication number.The place one's entire reliance upon reliability of changeless handset number and Marks of Network-entry License of the reliability of this method for anti-counterfeit, when they were forged, this method for anti-counterfeit will lose efficacy.Current, the instrument that is used to revise fuselage number is more and more, and the phenomenon of forging Marks of Network-entry License without permission is also increasing, therefore, is being faced with increasing challenge based on the reliability of the mobile phone method for anti-counterfeit of hand-set host fuselage number and Marks of Network-entry License.
In addition, can being used for the method for mobile phone on false proof, publication number is arranged is the digital network anti-fake technology (also being the inquiry anti-counterfeiting technology) described in the patent documentation of CN1617495A, its principle is to use the digital coding identification product, in central database, preserve the regular coding of every product, use modern coding and printing complex technique, be printed on coding on the product and covered, the consumer opens the coding top layer, by network, phone or mobile phone, coding is delivered to central database discern, just can differentiate the true and false of commodity quickly and easily.The coding of this method produces at random, and each commodity cipher does not repeat, and therefore can not fake in enormous quantities simply.In addition, this method criterion of identification is clear and definite, and the consumer does not need to be grasped specific sign identification method, just can directly inquire about the true and false of commodity to manufacturer, and with low cost, adapts to wide.But it also has significant disadvantages, as:
---coding is fixing, and figure case is many, and management expectancy makes things convenient for by phone, network or mobile phone short message enquiry inadequately than higher in making, storing process;
---if the only corresponding coding of every commodity, inquiry is once promptly cancelled so, identifies hiddenly, is difficult to look into afterwards earlier buy; If the corresponding a plurality of codings of every commodity, then buy a certified products after, other that is printed thereon not a plurality of codings of usefulness all may be collected and be used for faking;
---outward appearance is not distinct, and technology is fairly simple, is forged easily, and the fake producer can be printed on from establishing network and telephone service center from random coded and inquire address, a complete set of personation.
Therefore be sought after more reliable, advantages of simplicity and high efficiency method for anti-counterfeit more.
Publication number is to have introduced the false proof system and method with the statistics sales information of a kind of mobile phone based on note in the patent documentation of CN1581189A.In this system, handset number and anti-forge cipher are corresponding one by one; System implanted mobile phone with the program that sends false-proof short message automatically before every mobile phone is sold; Should automatically send the false-proof short message program has start self-starting, timing, extraction fuselage number and anti-forge cipher, sends false-proof short message automatically after the mobile phone power-on duration surpasses the setting-up time thresholding first, judges whether this false-proof short message sends success and whether close, stop or continue to send the function of this false-proof short message automatically according to sending result's decision.The weak point of this method is:
On the one hand, handset number and anti-forge cipher are corresponding one by one, and promptly password is constant, thereby have a large amount of effective old sign indicating numbers to be collected to be used for faking;
On the other hand, note is to send automatically, and the consumer can not affirm whether note really sends to regular cell phone manufacturer there, and the fake producer can be in random coded, inquire address, a complete set of personation from aspects such as establishing network and telephone service center;
Again on the one hand, because the restriction of time threshold makes the consumer not carry out Antiforge inquiry at the scene of buying mobile phone, promptly can't look into afterwards earlier and buy.
In recent years, introduced encryption technology in the commodity counterfeit prevention field, the method that is used for encryption anti-counterfeiting at present has the branch of fixed password mode and dynamic password mode.The password that the fixed password mode produces is constant, and the lawless person carries out anti-fake certificate as long as intercept and capture password with regard to this password being recycled and reused on other any mobile phone, reaches the purpose of imitation; And the password that the dynamic encryption mode produces is not changeless.
Publication number is to have introduced a kind of anti-counterfeiting technology based on dynamic password in the patent documentation of CN1617495A, and it is false proof that this technology also can be used for mobile phone.This technology is characterised in that: enterprise is that product is determined personal sign and is equipped with the device (dynamic password generating apparatus) that produces the authentication sign by application system, the user submits to Verification System to authenticate by communication network with personal sign with by the authentication sign that said apparatus generates, with the true and false of identification product.The every use of dynamic password generating apparatus once all can generate a new dynamic password according to the individual information (comprising personal sign) of certain cryptographic algorithm, key and object, and show; After Verification System receives the personal sign and dynamic password thereof of the needs identification that application system transmits, to in database, search out the corresponding individual information of realizing storage according to personal sign, calculate an authentication password according to these information with same algorithm, key and the synchrodata of dynamic password generating apparatus then, by checking the matching of this authentication password and the dynamic password that is identified, determine the true and false of product.Each authentication success, Verification System will be adjusted automatically synchrodata and upgrade according to this authentication password.This method and the digital network anti-fake technology of introducing above have similar defective, that is: utilize the dynamic password generating apparatus can generate a plurality of passwords, do not send to a plurality of passwords that Verification System authenticates in these passwords and all may be collected and be used for faking.Remove in addition, its weak point also shows as follows:
Because the every use of dynamic password generating apparatus once, the capital generates a new dynamic password according to the individual information (comprising personal sign) of certain cryptographic algorithm, key and object, and Verification System is then adjusted automatically synchrodata according to authentication password behind each authentication success and upgraded.When anti-fake certificate, Verification System need know that the dynamic password generating apparatus is which time generates new dynamic password, if new dynamic password of dynamic password generating apparatus generation and Verification System are adjusted automatically synchrodata and are upgraded so that produce authentication password next time inconsistent, as: mistake appears in the Network Transmission, more new data is asynchronous then can to cause authentication end and client, thereby can't reach the purpose of correct authentication, promptly can't reach the purpose of anti-fake certificate.
