Embodiment
Fig. 1 represents to be used to realize that data of the present invention revise the structure that the data of the present invention of the method for preventing are revised anti-locking system.Fig. 2 is the key diagram that data of the present invention are revised the method for preventing.
As shown in Figure 1, data are revised anti-locking system and are had the RFID label 1 that is installed on the product 100 and the read-write equipment (reader/writer) 2 of RFID label.Product 100 flows at least by i operation.I operation for example is current operation.I operation used intrinsic key 30i as described later.
Here, i is a positive integer, gets the value of 1～n.That is, under the situation of i=1, this operation is represented initial operation, and under the situation of i=n, this operation is represented final operation.To be expressed as read-write equipment 2i corresponding to the read-write equipment 2 extra token i of i operation.Other devices or part are identical therewith.
So-called operation is meant each stage in the circulation of the product 100 that RFID label 1 is installed.For example, production, processing, wholesale, retail etc.In addition, also can with wholesale be divided into 1 time wholesale, 2 times wholesale.That is, the supvr of system and/or user can at random define operation.In addition, operation also can be expressed as layer, level, process etc.
Therefore, product 100 in fact by comprise at least i operation and with afterwards (i+1) individual operation interior a plurality of operations (the 1st～a n operation).For example, make to comprise i a plurality of read-write equipments 2 that reach (i+1) individual read-write equipment 2i and 2 (i+1), i a plurality of operations that reach (i+1) individual operation are corresponding with comprising.A plurality of read-write equipments 2 are respectively mutually different device.
That is, a plurality of read-write equipments 2 use mutually different key 30 as described later, and the information of regulation is encrypted.In other words, can say so, that is, under the situation of using different keys 30, operation is different.Because a plurality of read-write equipments 2 except using mutually different key 30, are identical devices, so followingly mainly i read-write equipment 2 described.
The 1st read-write equipment 21 with own corresponding operation, promptly in the 1st operation (i=1), carries out following processing to RFID label 1.In RFID label 1, shown in Fig. 2 (A), what does not all write (perhaps, can (for example start) yet and write label ID).Read-write equipment 21 writes password ID in the beginning of RFID label 1 shown in Fig. 2 (B).Other zones that do not write password ID are storage areas of this RFID label 1, in addition, are the current data zone Ri (because i=1, institute thinks R1) in the read-write equipment 21.
I read-write equipment 2i carries out following processing with own corresponding operation, promptly in i operation to RFID label 1.That is, i read-write equipment 2i shown in Fig. 2 (D), makes the region R 1～R (i-1) that writes data in operation before this be the historical data zone in the storage area of RFID label 1, makes that region R i in addition is the current data zone.Historical data region R 1～R (i-1) be only can reading of data in i the operation the zone.Current data zone Ri is the zone that can write data in i the operation.In addition, Fig. 2 (C) is illustrated in the 2nd operation (i=2), makes that the current data zone R1 of the 1st operation is the state (this current data area is R2) of the 2nd the historical data region R 1 in the operation.
In other words, in the present invention, i read-write equipment 2i, in the storage area of RFID label 1, do not have the function of the data of writing for historical data region R 1～R (i-1), and only have the function of sense data, Ri then has the data function of writing for the current data zone.
In this example, historical data region R 1～R (i-1) is the beginning side of the storage area of RFID label 1, according to historical data region R 1, R2 ... the sequential storage of R (i-2), R (i-1).Current data zone Ri is the zone of following historical data region R (i-1), becomes the last zone up to the storage area of RFID label 1.Need in the Zone Full of current data zone Ri, not write data.The size separately (length) of historical data region R 1～R (i-1) is a variable-length.Therefore, current data zone Ri also is a variable-length.
I read-write equipment 2i with the user data Ui in i the operation, uses intrinsic key 30i to encrypt and write among the Ri of current data zone.User data Ui begins the place at it and inserts with symbol "＜" and "〉shown in Fig. 2 (D) " " beginning " word of bracketing, in its end insertion with symbol "＜" and "〉" " end " word of bracketing.＜the beginning〉be the special control information of the beginning of expression data, represent the beginning (beginning) of this user data Ui by it.＜eventually〉and be the special control information at the end of expression data, represent the end (end) of this user data Ui by it.In addition, as this control information, can use various marks.
(actual) user data Ui in i operation prevents that by essential information, record information and illegal copies information from constituting shown in Fig. 2 (D).In this example, the size of these information is respectively variable-length, and these information begin to write in proper order by this from the beginning of current data zone Ri.
Essential information is made of the essential information of the product 100 in i operation for example (in each operation general information).Specifically, the information by the title of product 100, goods title, the producer, form, model, place of production etc. constitutes.Thus, the user can understand essential information at any time.Record information is made of the information of the resume of for example representing product 100 (each operation intrinsic information).Specifically, constitute by the processor of product 100, qualification, machining location, circulation path, marketing channel etc.Thus, the user can understand record information at any time.Illegal copies prevent that information from being made of the information of the illegal copies that for example prevent this product 100.Specifically, constitute by the output of product 100, batch etc.Thus, by preventing the illegal copies of user data U (being RFID label 1), can prevent the illegal copies of product 100.
In addition, user data U can also comprise fabrication order information shown in the dotted line of Fig. 2 (D).Fabrication order information for example is made of the instruction that is used to make converted products 100.Thus, the user of i operation can pass on the instruction that is used to make converted products 100 to the user of (i+1) individual operation.
I operation is under the situation of the initial process (for example production process) in the actual operation, the operation before not having.That is, in the storage area of RFID label 1, there is not historical data region R 1～R (i-1).Therefore, under this situation, the integral body of the storage area of RFID label 1 is current data zone Ri, can write the user data Ui in this initial process.
Above processing also can similarly be carried out in the operation beyond i the operation.In order to make the relation between 2 continuous operations clear and definite, (i+1) individual operation is described.That is, in (i+1) individual operation, the read-write equipment 2 (i+1) of (i+1) individual operation makes historical data region R 1～R (i-1) in i the operation and current data zone Ri become the new historical data zone in (i+1) individual operation.On this basis, the read-write equipment 2 (i+1) in (i+1) individual operation makes zone beyond the new historical data zone become the new current data zone R (i+1) in (i+1) individual operation, carries out writing of user data in (i+1) individual operation.
The above results is that i and (i+1) individual read-write equipment 2i and 2 (i+1) use intrinsic key (30i and 30 (i+1)) respectively, and i user data Ui and U (i+1) that reaches in (i+1) individual operation encrypted and write.Thus, the user of each operation can store its record information, and the user of operation after sending to.After passing to RFID label 1, the user of each operation during the user of operation, generates the regional Ri of (identification) historical data region R (i-1) and current data repeatedly.
Fig. 3 represents that data of the present invention revise the example of concrete structure of the read-write equipment 2 of the RFID label 1 in the anti-locking system.
(i) read-write equipment 2 has control part 21, display part 22, input part 23, read-write portion 24, storage part 25, generating unit 26, Compress softwares portion 27, encrypting and decrypting portion 28.Encrypting and decrypting portion 28 has key list 29.I the employed unique key of read-write equipment 2i is called key 30i.
Read-write portion 24 is corresponding to the requirement from control part 21, reads user data U1～U (i-1) from the historical data region R 1～R (i-1) of RFID label 1, and user data Ui write the current data zone Ri of RFID label 1.User data Ui～U (i-1) that storage part 25 storages read out from the historical data region R 1～R (i-1) of RFID label 1.
The illegal copies that comprised among (promptly (i-1) individual operation) user data U (i-1) that generating unit 26 for example uses that the historical data region R (i-1) before recently reads out prevent information, (that is, i operation in) illegal copies that generation should write among the Ri of current data zone prevent information.In addition, illegal copies prevent that information from also can use the illegal copies among the user data U (i-1) before being included in recently to prevent that the illegal copies the information from preventing that information from generating.Compress softwares portion 27 utilizes well-known compression method corresponding to the requirement from control part 21, and the user data Ui that correspondence writes among the current data zone Ri of RFID label 1 carries out data compression.Encrypting and decrypting portion 28 is corresponding to the requirement from Compress softwares portion 27 (or control part 21), use is stored in any one key in the key list 29 as intrinsic key 30i, utilize well-known encryption method, to encrypting by the user data Ui after 27 compressions of Compress softwares portion.
Fig. 4 represents that data of the present invention revise the key list 29 that the read-write equipment 2 in the anti-locking system is had.
If product 100 circulations of this RFID label 1 have been installed, arrive i the operation corresponding with read-write equipment 2i, then read-write equipment 2i is selected in the key list 29 of reading or write middle use of this RFID label 1 corresponding to the password ID that reads from this RFID label 1.Then, read-write equipment 2i uses all keys of selected key list 29 in order, and the user data U1～U (i-1) in the storage area that writes this RFID label 1 is read, and corresponding to its result key is handled.
That is to say that the key that can use is used in any operation till (i-1) the individual operation before it in the reading of user data U1～U (i-1).Therefore, read-write equipment 2i deletes this key after preserving this user data U from key list 29.For example, remove the key XXX of password ID=1 ..., perhaps shown in Fig. 4 (B), all replace with " 0 " (being 0 entirely).Perhaps, also can all replace with " 1 " (being 1 entirely).
Thus, the user data U1～U (i-1) that writes in the operation till (i-1) is individual among the historical data region R 1～R (i-1) of RFID label 1 can read.In addition, because this key is deleted after reading, so in this i operation (read-write equipment 2i), can not be rewritten as in the user data Ui～U (i-1) that writes in the operation till (i-1) is individual in the RFID label 1 for forgery.That is to say, be treated as whole inseparable processing, can't carry out the rewriting of these data of reading by the deletion of reading the key of handling and in this is read, using of having used key.
On the other hand, the key of failing to use in the reading of user data U all uses in the operation till before (i-1) is individual.Therefore, read-write equipment 2i is shown in Fig. 4 (B), from this untapped key, select key arbitrarily at random, determine (use) its as intrinsic key 30i in this i operation, the user data Ui that will should write in this i operation encrypts, and is written among the current data zone Ri of RFID label 1.For example, generate the suitably random number of size, use this random number, start anew to count in order that remaining this untapped key gets final product in key list 29.Thus, can in this i operation, use unique key 30i, user data Ui is write in the RFID label 1.
In addition, be under the situation of the 1st operation in this operation, because do not read user data U, so become all untapped state of any one key.Therefore, the whole storage area of RFID label 1 all becomes current data zone Ri, selects intrinsic key from whole keys of key list 29.
Fig. 5 is that data of the present invention are revised and prevented processing flow chart, represents that data of the present invention revise the anti-performed data of locking system and revise and prevent to handle.
Under the state that makes the RFID label 1 that is installed on the product 100 near i read-write equipment 2i (read-write portion 24), the operator reads (step S11) from input part 23 indications.Corresponding with it, if control part 21 requires read-write portion 24 to read, then read-write portion 24 reads the content of historical data region R 1～R (i-1) of the storage area of RFID label 1, this content (also being referred to as reading of data) is delivered to control part 21, and control part 21 is stored to the regulation zone (step S12) that is used to store this information of storage part 25.In this reads, use the key of key list 29.Control part 21 is presented at (step 13) on the display part 22 with the content of historical data region R 1～R (i-1) that this reads out.Prevent information A as illegal copies, this content comprises for example A=100 (individual).
The operator who sees these contents is from input part 23 input data (step S14).At this moment, these input data comprise it and prevent information as illegal copies based on for example product 100 being divided into A1=60 (individual) and A2=40 (individual) carries out this fact of retail.According to this input, if control part 21 requires generating unit 26 to generate user data Ui, then generating unit 26 is used aforementioned input data, generates user data Ui, be presented on the display part 22, and be stored in the regulation zone (step 15) that is used to store this information of storage part 25.
After this, if control part 21 requires Compress softwares portion 27 to compress the user data Ui that is stored in the storage part 25, then Compress softwares portion 27 compresses this user data Ui, and then this user data Ui after requiring encrypting and decrypting portion 28 with 27 compressions of Compress softwares portion encrypts.Corresponding to this, encrypting and decrypting portion 28 uses any one key that is stored in the key list 29 as key 30i, and the user data Ui after the compression is encrypted, and is stored in the regulation zone (step S16) that is used to store this information of storage part 25.
Afterwards, if control part 21 requires read-write portion 24 to write, then read-write portion 24 will be stored in the user data Ui after the encryption in the storage part 25, write among the current data zone Ri of storage area of RFID label 1 (step S17).In this write, a key of key list 29 was used as intrinsic key 30i in this i operation.
Fig. 6 is that data of the present invention are revised and prevented processing flow chart, and reading of representing that data of the present invention revise that anti-locking system carries out handled and the removing of key is handled.This processing is carried out in the step S12 of Fig. 5.
Read-write portion 24 reads the password ID (step S21) of the storage area beginning of RFID label 1, and its content is sent into control part 21.Control part 21 is selected the key list 29 (step S22) corresponding with this password ID, empties register to be removed (not shown) (step 23).
Then, read-write portion 24 reads the content (2 Value Data) (step S24) of historical data region R (i-1) of the storage area of RFID label 1 from the outset in order, and its content is sent into control part 21.Control part 21 reads 1 key (step S25) in order from the beginning of key list 29, uses this key aforementioned reading of data to be deciphered (also being referred to as data decryption), decompress(ion), maintenance (step 26).Whether the beginning of the maintained data decryption of control part 21 inquiry exists by mark "＜" and "〉" " beginning " word (step S27) of having drawn together, if having, then inquire about whether to exist reaching "〉by mark "＜" " " end " word (step S28) of having drawn together.
In step S27, do not exist under the situation of " beginning " word, and in step S28, do not exist under the situation of " end " word, repeating step S25 and step afterwards.
In step S28, exist under the situation of " end " word, control part 21 will be by the data in " beginning " word and " end " zone that word comprises as user data U1～U (i-1), be stored in the regulation zone (step S29) that is used to store this information of storage part 25, will be stored in the pairing key of waiting to remove in the register of password ID and from key list 29, remove (step S210), to be stored at the password ID of employed key in the reading of this user data U1～U (i-1) and wait to remove in the register, and make this key for treating removing state (step S211).
Afterwards, control part 21 inquiry remaining untreated key (step S212) whether in key list 29, if remaining, then repeating step S25 and after step.If not remaining, then not will be stored in the pairing key of waiting to remove in the register of password ID and from key list 29, remove end process.
Writing in the processing after this reads processing, as previously mentioned, the illegal copies that use should write the data among the Ri of current data zone and be stored in the user data U (i-1) in the storage part 25 in step S29 (being step S12) prevent that information (for example, with reference to figure 7) encrypt, generate user data Ui (step S16) thus.At this moment, unique key 30i selects from the residue key of not removing key list 29 randomly.
In addition, RFID label 1 can use the user data U (i-1) that is stored in the data that should write among the Ri of current data zone and the step 29 in the storage part 25, duplicates.As previously mentioned, reading processing can only carry out once.Therefore, as long as step of replacing S11～S13, reading user data U1～U (i-1) of being stored in the aforementioned storage part 25 afterwards, execution in step S11～S17 gets final product.In duplicating, this also as previously mentioned,, can prevent revising of data because can not rewrite historical data region R 1～R (i-1).
Fig. 7 is that explanation data of the present invention are revised the figure of the practical application of the method for preventing, expression uses data of the present invention to revise the method for preventing when partitioning products 100.
According to the present invention, as an example, illegal copies prevent that information from being made of the value that product 100 is cut apart.And the illegal copies that are written among the prime area R1 in historical data region R 1～R (i-1) prevent information A, are made of product 100 alienable maximal values.Under such condition, read-write equipment 2 is shown in Fig. 7 (A), make that one or more illegal copies that are written into prevent information in historical data region R 1～R (i-1) with S and the illegal copies that in the Ri of current data zone, are written into prevent information A i's and, equal maximal value.That is, make A=S+Ai.
For example, making maximal value is A.A for example can get " individual " and various units such as " open ".For example, in the operation that begins most, produce under the situation of 100 products 100 that indicate same batch of number A=100 (individual).In next operation, sell under the situation of A1 (individual) and this product 100 of A2 (individual) A=A1+A2 to the processor of 2 companies.And in next operation, the processor who buys A1 (individual) sells under the situation of A11 (individual), A12 (individual) and A13 (individual) A1=A11+A12+A13 to 1 wholesale person of 3 companies.And in next operation, 1 the wholesale person who buys A12 (individual) sells under the situation of A121 (individual), A122 (individual), A123 (individual) and A124 (individual) A12=A121+A122+A123+A124 to 2 wholesale persons of 4 companies.Therefore, in Fig. 7, for example be A=A11+ (A121+A122+A123+A124)+A13+A21+ (A221+A222).
Therefore, shown in Fig. 7 (B), have the RFID label 1 that illegal copies prevent information A 122, have its all upper illegal copies and prevent information A, A1, A12, A122.By relatively being installed in the RFID label 1 on the product 100,, it can both be checked out if the data in any one operation are revised.Thus, in each operation, in fact can't rewrite its illegal copies and prevent information.Therefore, can not rewrite the data that write in the RFID label 1, can prevent illegal operation, improve its trace ability product 100.
Fig. 8 is that explanation data of the present invention are revised the figure of the practical application of the method for preventing, the of the present invention data of expression under the situation of assembling, integrated product 100 are revised the method for preventing.
