Description

The present invention relates to a data structure of a wireless tag using a non-contact IC chip and an information processing apparatus for reading the wireless tag.

Conventional wireless tags generally have a rewrite memory. Although the rewritable memory has the convenience of freely rewriting the contents of the memory, there is a possibility that a counterfeit wireless tag can be created by rewriting. Various techniques have been used to prevent forgery of objects. For example, banknotes are genuine using special manufacturing techniques such as microprinting and watermarking, and in the case of credit cards, holograms are used to prevent counterfeiting.

FIG. 1 shows a transmission / reception relationship of main information for implementing a product authenticity determination system that determines the authenticity of a product using a wireless tag. FIGS. 1 shows an embodiment of a product authenticity determination system for determining the authenticity of a product.

In FIG. 1, the basic number management company 1 manages the number of data stored in the wireless tag 50. The basic number management company 1 has a business contract with a product manufacturer 2 that uses the wireless tag 50 to manage the assignment of numbers, which are data stored in the wireless tag 50. Then, the number subjected to the allocation management is stored in the wireless tag 50, and the wireless tag 50 storing the number is stored in the wireless tag by the authenticity determination device 30 in which the number for which the allocation management has been performed is recorded in advance. The authenticity of the wireless tag 50 can be determined by collating the numbers.

This basic number management company 1 has a processing device having a configuration as shown in FIG. That is, the processing device 10 has the CPU 11, and the processing is performed by the CPU 11. The CPU 11 is connected to a man-machine interface 12 via a bus line, and a storage device as various databases via the bus line. The man-machine interface 12 performs processing (data writing, reading, and the like) of the processing device 10. The storage device includes a product manufacturer database 13, an assigned service identifier database 14, an assigned service data (number) database 15, an additional assigned service data (number) database 16, and an error chip service data (number) database 17.

In FIG. 2 to FIG. 3, the basic number management company 1 concludes a business contract with the product manufacturer 2 that uses the wireless tag 50 to manage the assignment of numbers as data stored in the wireless tag 50, and FIG. The manufacturer is registered in the product manufacturer database 13 (1502). After concluding this business contract, the product manufacturer 2 requests the basic number management company 1 to allocate a service identifier (1504). The basic number management company 1 which has received the service identifier allocation request from the product manufacturer 2 performs a service identifier allocation process on the requesting product manufacturer 2 and allocates the service identifier to the allocation service identifier database 14 in FIG. The registered service identifier is registered (1506). The basic number management company 1 that has performed the service identifier assignment processing notifies the assigned product identifier (for example, a 3-bit number) to the product manufacturer 2 that is the requester (1508). Along with the notification to the product maker 2, the service identifier (for example, a 3-bit number) assigned to the genuineness determination device maker 3 that manufactures the genuineness determination device that reads the data stored in the wireless tag 50 is notified. (1510). Alternatively, the product manufacturer 2 may notify the authenticity determination device manufacturer 3 in some cases.

The authenticity determination device manufacturer 3 having received the notification of the assigned service identifier (for example, a 3-bit number), determines the authenticity based on the assigned service identifier notified from the basic number management company 1. The device 30 is manufactured (1512). The manufactured authenticity determination device 30 distributes the products to intermediate wholesalers and retail stores that determine the authenticity of the products (1514). Also, the chip manufacturer receives the notification of the assigned service identifier and manufactures the chip, similarly to the authenticity determination device manufacturer 3.

On the other hand, the product manufacturer 2 that has been notified of the assigned service identifier (for example, a 3-bit number) notifies the basic number management company 1 of the required number of service data (numbers) based on the assigned service identifier. ) (For example, 100,000 for the user data S size of a specific product) (1516). The basic number management company 1 that has received a request to allocate a required number of service data (numbers) from the product manufacturer 2 performs service data (number) allocation processing to the product manufacturer 2 as a requester. The assigned service data is registered in the assigned service data database 15 of No. 4 (1518). The basic number management company 1 that has performed the process of assigning the service data (number), based on the assigned service data (number), together with the product manufacturer, assigns the service identifier and the assigned service identifier to the chip manufacturer 4. The service data (number) is notified, and a request is made to manufacture a chip storing the allocated service data (number) (1520).

(4) Upon receiving a chip manufacturing request from the basic number management company 1, the chip manufacturer 4 manufactures a chip in which the assigned service identifier and service data (number) are stored (1522). When the chip manufacturer 4 manufactures a chip storing the assigned service data (number), the chip manufacturer 4 sends the manufactured chip to the tag manufacturer 5 and requests manufacture of a tag in which the chip is embedded. (1524). Upon receiving the request for manufacturing the tag, the tag manufacturer 5 manufactures the tag using the chip sent from the chip manufacturer 4 (1526). When the tag is manufactured by the tag manufacturer 5, the manufactured tag is sent to the product manufacturer 2 (1528). The manufactured tag is attached to the product at the product manufacturer 2 (1530). The service identifier (for example, a 3-bit number) assigned by the basic number management company 1 is not always used, and the tag is manufactured using the manufactured chip at the chip manufacturing stage in the chip manufacturer 4. At this stage, some defective products may be generated. In this case, the defective tag and the assigned service identifier (for example, a 3-bit number) stored in the chip are missing. The missing assigned service identifier (for example, a 3-bit number) is stored in the error chip service data (number) database 17 shown in FIG.

(4) Similar to the chip manufacturer, the authenticity determination device manufacturer receives the notification of the assigned service data and manufactures the authenticity determination device.

{Circle around (2)} The product manufacturer 2 requests the basic number management company 1 to additionally allocate service data (service ID) (1532). The basic number management company 1 that has received a request for additional allocation of new service data (service ID) from the product manufacturer 2 performs an additional service ID allocation process for the product manufacturer 2 as a requester. The new service data assigned to the additional assignment service data database 16 is registered (1534). The basic number management company 1 that has performed the process of assigning the additional service ID assigns the assigned service ID to the manufacturer 3 of the authenticity determining device that manufactures the authenticity determining device that reads the data stored in the wireless tag 50 together with the product manufacturer. An additional service ID (for example, a 3-bit number) is notified (1536).

The authenticity determination device manufacturer 3 that has been notified of the assigned additional service ID (for example, a 3-bit number) based on the assigned additional service ID notified from the basic number management company 1. A program for reading the additional service ID is written in the false determination device 30 (1538).

In addition to the notification to the authenticity determination device manufacturer 3, the basic number management company 1, which has performed the additional service ID allocation process, sends a chip manufacturer 4 based on the allocated service ID (number). The assigned service ID (number) is notified, and a request is made to manufacture a chip in which the assigned service ID (number) is stored (1540).

(4) Upon receiving a chip manufacturing request from the basic number management company 1, the chip manufacturer 4 manufactures a chip in which the assigned service ID (number) is stored (1542). When a chip storing the assigned service ID (number) is manufactured in the chip maker 4, the manufactured chip is sent to the tag maker 5, and a request is made to manufacture a tag in which the chip is embedded. (1544). Upon receiving the request for manufacturing the tag, the tag manufacturer 5 manufactures the tag using the chip sent from the chip manufacturer 4 (1546). When the tag is manufactured by the tag manufacturer 5, the manufactured tag is sent to the product manufacturer 2 (15548). The manufactured tag is attached to the product at the product manufacturer 2 (1550). The service ID (for example, a 3-bit number) assigned by the basic number management company 1 is not always used, and the tag is manufactured by using the manufactured chip in the chip manufacturing stage in the chip manufacturer 4. At this stage, some defective products may be generated. In this case, the defective service tag and the assigned service ID (for example, a 3-bit number) stored in the chip are missing. The missing service ID (for example, a 3-bit number) is stored in the error chip service data (number) database 17 shown in FIG.

The service identifier can be added by the same procedure as the service ID.

FIG. 5 shows a flowchart of a member registration process on the merchandise manufacturer 2 side so that the merchandise manufacturer 2 becomes a member of the basic number management company 1.

In the figure, in step 1602, the product manufacturer 2 applies for membership registration to the basic number management company 1. In this step 1602, when the product maker 2 makes an application for membership registration to the basic number management company 1, in step 1604, the basic number management company 1 sends to the product maker 2 the input items ( Business name, address, contact information, business type, telephone number, capital, password, etc.), and the product manufacturer 2 receives the input items necessary for this member registration. When the product manufacturer 2 receives the input items required for member registration in step 1604, the product manufacturer 2 inputs the input items required for member registration received from the basic number management company 1 in step 1606.

FIG. 7 shows the configuration of a non-contact IC chip used by such a product manufacturer 2.

In the figure, the IC chip 102 includes an antenna unit 104, a power supply unit 106, a logic unit 108, and a memory unit 110. The non-contact IC chip does not have a contact point, and transmits radio waves from the reader to the antenna unit 104 to supply power and transmit and receive a clock and data. Some antennas are provided in an IC chip, and some have an antenna outside. FIG. 7 assumes that a chip has an antenna section. In the case where the antenna section is provided outside the chip, the antenna section is externally attached to the chip. In the present invention, whether the antenna section is inside or outside the chip is not affected by the system, and can be applied to both. There are several methods such as electromagnetic induction as a non-contact method between the reader and the antenna unit. The present invention can be applied to any of them.

Next, the operation of the IC chip will be described. First, a radio wave is received by the antenna unit 104, the power is changed to a power supply by the power supply unit 106, and a power supply used in a circuit of the entire IC chip is generated. The radio wave received by the antenna unit 104 extracts a clock component and is used as a clock of a circuit of the entire IC chip. The logic unit 108 performs processing according to a command sent from the reading device. The memory unit 110 is an area for storing information to be stored in the IC chip. The IC chip used for the wireless tag of the present invention uses a non-rewritable ROM as a memory in a memory unit. Since the data of the ROM-type wireless tag is written at the time of manufacturing at the factory, even if the tag is passed to the customer, the data cannot be changed. Since the RAM-type wireless tag allows a customer to write data, it is dangerous to use the RAM-type wireless tag to prevent forgery.

FIG. 8 shows an embodiment of the wireless tag. This wireless tag is formed by attaching antennas 206 and 208 for transmitting and receiving to and from a reading device to a non-contact IC chip 204, and sandwiching between them by a seal 202 for reinforcement.

FIG. 9 is a diagram showing a data structure of the wireless tag.

In the figure, a wireless tag data structure 302 includes a service identifier 304 commonly assigned to a specific application or category, a wireless tag having unique data for categorizing within a specific application or category, and the same service identifier. The service data 306 holds a serial number which can identify the service data. An EDC (Error @ Detecting @ Code) 308 is for checking a data reading error. The EDC has the same function as the parity used for parity check for confirming data consistency of tag information. Check EDC and use only normal data. Data that does not satisfy the EDC check is treated as invalid data. In order to confirm whether a product is genuine, read the tag information of the wireless tag attached to the product and treat it as genuine if it contains the service identifier assigned to the product. Can be. By reading the tag information of the wireless tag-attached object to which the wireless tag is attached in this manner, if a valid service identifier is included in the tag information, the ROM-type wireless tag can be regarded as genuine. Can be used.

(4) The service data can include a serial number used for managing individual products, information indicating a production time, a product version, and data indicating a detailed type of the product. Although the appearance of the product is the same, service data can be used when it is desired to attach a version or a detailed type.

In conventional ROM-type wireless tags, sequential data is stored, so in order to confirm whether or not the product is genuine, it is necessary to check with the sequential data attached to the product, and the communication cost for verification is high. Could take. In this embodiment, if only the service identifier is confirmed, it can be confirmed whether or not it is genuine. The RAM-type wireless tag does not have a high forgery prevention capability because a service identifier can be easily written as tag information.

FIG. 10 is an embodiment showing that the length of a plurality of types of service identifiers is taken as the data 302 of one wireless tag. Since service data can also store user data, certain applications require long service data, and the wireless tag of the present invention uses a large number of service identifiers in order to be applicable to many applications. It is desirable that the length of the service identifier be long so that it can be used. If the length of the data used for the service identifier is 10 bits, only 1024 applications can be applied. On the other hand, if the length of the data used for the service identifier is 32 bits, it can be applied to about 4.2 billion services. In general, since the entire data length of a wireless tag is constant, if the length of EDC is also constant, the longer the data length of the service identifier, the shorter the data length that can be used for service data. As described above, if a plurality of data lengths of the service identifier are prepared, there is an advantage that service data having a long data length can be used for necessary applications and can be used for many applications.

In this embodiment, the service header 404 has a length of 2 bits so that four types of service identifiers can be identified. The service identifier 406 of the data 402 is 10 bits, and the data lengths of the service identifier 416, the service identifier 426, and the service identifier 436 are 14 bits, 24 bits, and 36 bits, respectively. The number of these bits determines the number of service identifiers that can be provided and the length of service data. The 36-bit service identifier is such that a code corresponding to an EAN code (international article number code) can be used as the service identifier.

FIG. 11 shows an embodiment of an information processing device 502 for reading a wireless tag. The information processing device 502 for reading a wireless tag has an antenna 504 for communicating with the wireless tag. When the switch 508 is pressed to read data, a radio wave is transmitted from the antenna 504 to the wireless tag 510, and the wireless tag returns the result to the antenna 504. The information processing device 502 displays the processing result on the display 506.

FIG. 12 shows an embodiment in which the information processing apparatus 502 performs information processing using the service identifier returned from the wireless tag. The information processing device 502 stores the service identifier of the genuine wireless tag in the service identifier recording unit 608. The service identifier recorded in the service identifier recording unit 608 is compared with the service identifier included in the read tag information of the wireless tag, and is used to determine that the service identifier is authentic if the service identifier is the same.

To determine whether an object is genuine, first, when a wireless tag is approached to the information processing device 502 or when a component with the wireless tag is used in the information processing device 502, In the device 502, the tag information sent from the antenna 504 by a wireless tag is read by the tag information reading unit 606. In the “operation control unit based on service identifier” 610, it is determined whether or not the read service identifier is the same as the one recorded in the service identifier recording unit 608. In the service identifier recording unit 608, a service identifier regarded as genuine is recorded in advance when the information processing apparatus is shipped.

動作 The operation based on the judgment / collation result has various operation controls depending on the application. For example, if they are the same, the operation unit 612 is instructed to display "real" or to open the door. If they are not the same, the operation unit 612 is instructed to display "not real" or to not open the door. If the information processing apparatus 502 is a printer or a toner, the information processing apparatus 502 can be used to check whether the wireless tag is genuine by attaching a wireless tag to an ink tank or the like. If the information processing device 502 is an electric appliance, it is possible to confirm whether or not the component is genuine by attaching a wireless tag to a battery or a component. If the information processing device 502 is a car, by attaching a wireless tag to a tire, it is possible to confirm whether a genuine tire or an appropriate tire is attached. By displaying the determination result, interrupting the operation, or issuing a warning that the operation is not appropriate as described above, it is possible to prevent a wrong component from being attached and prevent improper operation.

FIG. 13 shows an example of information processing 502 using service data information in addition to the service identifier. Recognition of an object using only a service identifier cannot be detected if a problem arises when an object in the information processing 502 is reused. This embodiment is used to detect reuse by using a serial number written in service data in tag information of a wireless tag. If the service identifier recorded in the service identifier recording section 708 in the “operation control section based on service identifier” 710 and the service identifier read in the tag information reading section 704 are the same, the operation is controlled by the operation control section 714 based on service data. The service data and the service data recorded in the service data recording unit 716 are determined and collated. If they match, it is regarded as reused, and the operation in the case of reuse is instructed to the operation unit 712. If they do not match, the read service data is recorded in the service data recording unit 716. Then, the operation in the case of being used for the first time is instructed to the operation unit 712. If there is no more memory for storing service data read by the service data recording unit 716, the oldest service data is deleted. The operation of the operation unit 712 when reused differs depending on the application.

An embodiment in which the information processing apparatus shown in FIG. 13 is applied to a device using consumables such as a copying machine will be described. In a device that uses consumables, such as a copying machine, it may be necessary to determine whether a component for replenishing consumables is appropriate. If the parts are not appropriate, the device is damaged or a serious problem occurs in operation. In such an application, when the tag information is read when a component is mounted or the device is turned on, the usage status of the component is separately grasped, and the service data recording unit 716 stores the continuous data in the service data. Record the number and usage set. When the tag information is newly read when the component is mounted, and the usage status grasped separately from the serial number in the service data does not match the information recorded in the service data recording unit 716, the normal component However, regarding the use of the components, control is performed such as displaying the status, interrupting the operation, or issuing a warning that the operation is not appropriate. As an example of inconsistency, when the service data recording unit 716 reads a new serial number of service data even though the contents of consumables of a component having a serial number of a certain service data are recorded as empty, This is the case when the contents are full. In such a situation, the component is subjected to improper processing, which may lead to an accident such as damage to the device. Therefore, for example, the operation unit performs a process of stopping the use of the component.

As an embodiment in which the information processing apparatus in FIG. 13 is applied to an entry / exit management device, a device that permits entry into a room by holding a card with a built-in wireless tag over it will be described. The tag information reading unit 706 reads the tag information of the wireless tag. The “operation control unit based on service identifier” 710 checks whether the service identifier of the read tag information is the same as the service identifier stored in the service data recording unit 716. If the service identifiers are not the same, the process ends without opening the door. If the service identifiers are the same, the operation control unit 714 based on the service data determines whether or not the service data in the read tag information is the same as the service data recorded in the service data recording unit 716. If the collation result is the same, the operation unit 712 is instructed to open the door. If they are not the same, do not open the door. The service data recording unit 716 stores in advance the service data of the wireless tag that can be used only once, the service data of the wireless tag that can be used only on the same day, the service data of the wireless tag that can be used only on a specific day, and the wireless data that can be used only for a certain period. By storing the service data of the tag, the operation control unit 714 based on the service data can perform control to open the gate only within the permitted range. If the wireless tag is used under the permitted condition, the contents of the service data of the wireless tag are deleted from the service data recording unit. By doing so, it becomes impossible to enter the room with the tag.

If the tag information of all the wireless tags that can enter the room is used, all the tag information of the wireless tags that can enter the room is stored in the service identifier recording unit 608 in the configuration of FIG. The tag information read by the tag information reading unit 604 is compared with all the tag information stored in the service identifier recording unit 608, and if the same tag information is recorded, the operation unit 612 is instructed to open the door. . Also in the present embodiment, by storing the number of times that the user can enter the room and the date in the service identifier recording unit 608 in combination with the tag information of the wireless tag, the control for opening the gate only within the permitted range can be performed by the “service identifier. The operation control unit 610 makes this possible.

(4) When using a service identifier to determine whether or not the service is genuine, it is necessary to add a genuine service identifier because, for example, the types of usable parts have increased. Although the data of the service identifier recording unit 608 can be updated by another input means of the information processing apparatus, it is preferable that the service identifier can be updated using a wireless tag. Specifically, the product manufacturer may distribute a new product that requires a new service identifier and, at the same time, distribute a wireless tag for updating the service identifier together with the information. No trouble in updating the department.

First, an embodiment of a wireless tag using a special service identifier for newly adding a service identifier will be described. FIG. 14 is a diagram illustrating the service identifier of the wireless tag according to the present embodiment and the contents of the service data. A service identifier 806 for adding a service identifier is used as the service identifier 804 of the present embodiment. The service data 816 stores an original service identifier 808, a service identifier 810 to be added, unique data 812, and a serial number 814. The original service identifier 808 corresponds to the service identifier 304 used for confirming the authenticity, and is already recorded in the service identifier recording unit.

FIG. 15 shows an embodiment of an information processing apparatus that reads a wireless tag including the service identifier 804 and the service data 816 in FIG. 14 and adds a service identifier. The service identifier 804 of the tag information of the wireless tag read by the tag information reading unit 906 is identified by the “operation control unit based on service identifier” 910. FIG. 16 shows the processing procedure. First, it is checked whether or not the content of the read service identifier is the service identifier for adding service identifier 806 (1006). If not, it is checked whether the contents of the read service identifier are recorded in the service identifier recording unit 908 (1008). If it is recorded, the operation control unit 914 based on the service data is notified that the service identifiers match. The operation control unit 914 based on the service data performs processing to confirm that the wireless tag is correct. If not recorded, it notifies the operation control unit 914 based on the service data that the service identifiers do not match. The operation control unit 914 based on the service data performs a process of determining that the wireless tag is inappropriate, for example, a fake. This process is the same as the process shown in FIG.

If the content of the read service identifier is the service identifier for adding service identifier 806, it is checked whether the existing service identifier 808 stored in the service data is recorded in the service identifier recording unit 908 (1014). If it is not recorded, the fact that the existing service identifier of the service data is not recorded is notified to the operation control unit based on the service data (1016), and processing is performed assuming that the wireless tag is not appropriate. If it is recorded, the service identifier (810) to be added is additionally recorded in the service identifier recording unit (908) (1018). Thereafter, the fact that the existing service identifier is stored in the service data is notified to the operation control unit based on the service data (1020), and processing as an appropriate wireless tag is performed.

In the present embodiment, the service identifier is additionally recorded in the service identifier recording unit 908 by the operation control unit 910 based on the service identifier (920).

Next, FIG. 17 shows an embodiment of a wireless tag for adding a new service identifier to an information processing device using an existing service identifier. The service identifier 1104 stores an existing service identifier 1106. This is the same as normal usage. The service data 1116 of this embodiment has a data area for a service identifier addition flag 1108 indicating that the service identifier 1112 to be added is included in the service data. If the service identifier addition flag 1108 is “ON”, it indicates that there is a service identifier 1110 to be added after the service identifier addition flag 1108, and if “OFF”, the service to be added after the service identifier addition flag 1108. Indicates that there is no identifier 1110. The unique data 1112 and the serial number 1114 are the same as those used in the embodiments of FIGS.

FIGS. 18 and 19 show an embodiment of the “operation control unit based on service identifier” 1210 of the information processing apparatus when adding a service identifier using the wireless tag using the data shown in FIG. First, the operation control unit 1210 based on the service identifier checks whether the service data identifier of the tag information read by the tag information reading unit 1206 is the service identifier recorded in the service identifier recording unit 1208 (1306). Otherwise, it notifies the operation control unit 1214 of the service data that the information is not recorded (1308). If so, it is checked whether the service identifier addition flag of the service data is ON (1310).
