＜embodiment flow process 〉
Fig. 2 is method flow diagram, coordinates hardware structure shown in Figure 1, further illustrates the present invention.
＜1. initialization 〉
● step 200: the electronic chip 32 in RFID label 30 is write identification code UID and the first identifying code (being the chip checking code) CA.For the purpose of identifying, for unique and in general can't revise, and generally given by the producer institute of RFID label 30 at the corresponding RFID label 30 of the value of this identification code UID.In this step, the value of chip checking code CA is preferably a random number, and generally when opening card (or) ability is given when wish is used RFID label 30.Optionally, when identification code UID and/or chip checking code CA write fashionablely, can encrypt separately, and improve security, but this is not necessity of the present invention.
● step 202: database D B (can be arranged on the identification code UID of (i.e. " high in the clouds ") store electrons chip 30 on user's terminal 10 or far-end server 20 and the second identifying code (namely with reference to identifying code) RA of corresponding chip checking code CA, and identification code UID is associated to reference to identifying code RA.Preferably, has identical value with reference to identifying code RA with step 200 chips identifying code CA in step 202, with as between the two corresponding relation.In addition, database D B can record the related data IF of RFID label 30 accompanying article in addition, for revene lookup in the future.
＜2. checking 〉
● step 204: user's terminal 10 starts application A P, to carry out the checking to RFID label 30, wherein application A P first sends the RF signal by electronic chip access module 112 (RFID access module), by this electronic chip 32 on RFID label 30 is sent reading requirement, and receive identification code UID and chip checking code CA that electronic chip 32 returns.If the identification code UID of passback and chip checking code CA are through encrypting, application A P needs in addition identification code UID and chip checking code CA to be decrypted.
● step 206: whether this step determines chip checking code CA and conforms to reference to identifying code RA.In this example, after application A P obtains identification code UID and chip checking code CA, with the associated reference identifying code RA of identification code UID in identification code UID Query Database DB, and judge chip checking code CA and whether conform to reference to identifying code RA.At this, if application A P judgement chip checking code CA with have identical value with reference to identifying code RA, assert chip checking code CA with reference to identifying code RA for conforming to, but the present invention ought be not limited to this.
Should be noted that in addition, be arranged in the embodiment in server 20 (i.e. " high in the clouds ") at database D B, also can carry out above-mentioned judgement by server 20 assistance application AP, in this embodiment, application A P only needs to send identification code UID and chip checking code CA to server 20 by communication module 108, and server 20 can replace application A P to find chip checking code CA, and judge chip checking code CA and whether conform to reference to identifying code RA, then judged result is returned to application A P.
● step 208: if judgment result is that in step 206 conforms to, application A P produces one and is verified message (not shown) on display screen 102, optionally, also the related data IF of the RFID label 30 accompanying article that record in database D B can be shown in display screen 102 in the lump.
＜3. upgrade identifying code 〉
● step 210: outside step 208, if judgment result is that in step 206 conforms to, application A P voluntarily (or by server 20 (i.e. " high in the clouds ")) produce at random another random number R N, and upgrade chip checking code CA and value with reference to identifying code RA based on this random number R N.For instance, can be directly with this random number R N as chip checking code CA with upgrade with reference to identifying code RA after value.In addition, the chip checking code CA after application A P will upgrade by electronic chip access module 112 (RFID access module) writes to electronic chip 32, to replace old chip checking code CA.When after when carrying out step 204-208 again, use the chip checking code CA that upgrades and value with reference to identifying code RA.
Preferably, in step 210, random number R N's is produced as random and is not to produce based on any algorithm, and the chip checking code CA after upgrading has nonreversibility with value with reference to identifying code RA, in other words, chip checking code CA after renewal can't be predicted with there is no with reference to the value of identifying code RA that any rule can be followed, therefore significantly promote security, and remove the required computational resource of execution algorithm from.
The imitation gimmick of general electronic chip, to have copied specific electron chip 32 identification code UID and initial chip checking code CA in a large amount of imitation chips, but namely be updated through after one-time authentication because chip checking code CA is every, the initial chip checking code CA that namely is not updated namely loses effectiveness, therefore the embodiment of the present invention at most only allows that the electronic chip of an imitation passes through checking, and this is enough to reach the mass-produced purpose that prevents from forging chip.
On the other hand, preferably, the problem that when the chip checking code CA after upgrade writes to electronic chip 32, failure causes, electronic chip 32 has the backup field with database D B, chip checking code CA after application A P confirm to upgrade successfully writes to electronic chip 32, and application A P just can carry out in database D B the more new element with reference to identifying code RA.
In a further embodiment, allow step 204 and step 208 repeatedly to carry out, and namely carry out the renewal of step 210 after not necessarily judgement conforms in each step 208, as shown in the dotted arrow in Fig. 2.On the contrary, application A P (or by server 20 (i.e. " high in the clouds ")) voluntarily provides the function of a counter (not shown), conform to if be judged as in each step 208, counting adds 1, if counting arrives a preset value (for example 5), just upgrade chip checking code CA and with reference to identifying code RA, can reduce by this load of system with random number R N.
It should be noted that in addition, in the above-described embodiments, application A P should be considered to equate by user's terminal 10 own resources or the action of completing by the assistance (i.e. " high in the clouds ") of server 20 in the present invention, and all can be considered to performed by user's terminal 10, even the storage of most data all is responsible for by server 20 with processing.
In the situation that do not break away from the present invention's spirit or necessary characteristic, can other particular forms embody the present invention.Described specific embodiment each side only should be considered as illustrative and non-limiting.Therefore, scope of the present invention is as enclosing as shown in claims but not as shown in above stated specification.All drop on the equivalent meaning of claims scope and the change in scope should be considered as dropping in the scope of claims.
