Description

  The present invention relates to an anti-theft system, and more particularly to an anti-theft system suitable for preventing theft (shoplifting) of software such as a personal computer.

Traditionally, for theft of goods at retail facilities such as retail stores, especially shoplifting, guards were patrolled or dedicated security guards pretending to be customers were dealt with shoplifters individually. . In addition, video cameras were placed in the store to monitor shoplifters. However, each method has a limit, and it has not been able to cope with a clever trick. Therefore, when a radio transmitter is attached to mainly expensive products, and there is a person who wants to take unsettled goods out of the store, the gate equipped with a system that receives and reports the signal transmitted from this radio transmitter exits the gate A method has been developed for reporting to shop assistants. In this case, since the radio transmitter is expensive, the register person removes the radio transmitter from the product and reuses it without discarding when the product is legally settled. However, in this case, it is possible for shoplifters to remove the radio transmitter from the product in the store and discard it, and the product that has been removed passes through the gate equipped with a system that detects the radio transmitter. However, there was a problem that it could not be detected.
In addition, when the product sold at the sales facility is application software, the product is sold by attaching a sticker on which ID information is visually recorded by printing on a package storing a storage medium storing the software. In general, the purchased customer can use the software only after visually confirming the printed ID and inputting a key when the storage medium is set on the PC and used. Therefore, when shoplifting is performed for each package, the software can be used by an unauthorized purchaser and cannot be a true shoplifting prevention measure.
In addition, as a conventional technique, Japanese Patent Application Laid-Open No. 2003-141650 discloses an article identification sign with an anti-theft function and an article management system using the article identification sign. In an article identification sign that is attached to an article and includes information about the article An article identification sign comprising an anti-theft tag part for monitoring movement of an article and an RF tag part capable of reading and writing information by wireless communication for individual identification of the article Has been.
JP 2003-141650 A

As described above, in the conventional software anti-theft measures, when shoplifting is performed for each software storage medium displayed in the store, the ID is visibly printed in advance on the package. It was possible to install and use. Therefore, there is no way to prevent theft other than monitoring the storage medium itself, and a radio transmitter etc. must be attached to each package, and a gate to receive radio waves from the radio transmitter must be provided at the outlet. There is a problem that the equipment cost increases.
In addition, the prior art disclosed in Patent Document 1 attaches an anti-theft tag and an RF tag to an article, holds on / off information in the anti-theft tag, and in the case of unsettled not passing through the cash register, the shoplifter is Since the article whose information is still on is held and goes out of the store, theft is prevented by detecting this by the detecting means provided at the exit. Therefore, in the point that there is no method to prevent theft other than monitoring the taking-out of goods, it is necessary to provide a gate for receiving this radio wave at the exit as well as the software anti-theft measures, and the facility cost of the store increases. There is.
In view of such a problem, the present invention attaches an individual identification number to each storage medium, particularly when preventing theft of the storage medium storing the software, and only the customer who purchased the storage medium for the regular ID. It is an object of the present invention to provide an anti-theft system that enhances secrecy by giving it from a center server, enables accurate ID management with a reliable method, and exhibits great deterrence against shoplifters.

In order to solve this problem, the present invention provides an anti-theft system for preventing illegal storage of a storage medium storing software from a sales facility, and storing an identification number storing the software identification number. Means, a reading means for reading the identification number stored in the identification number storage means, a register having a communication function for storing the presence / absence of settlement of the commodity price and the identification number read by the reading means, and transmitting from the register A center server for transmitting an ID corresponding to the identification number to the register, and a visualizing means for visualizing the ID, and the identification number stored in the identification number storage means By transmitting to the center server via a register, the center server converts the received identification number into a corresponding ID and returns it to the register And it features.
The most significant feature of the present invention is that the identification number stored in the identification number storage means cannot be used as an ID, so that the software attached to the PC cannot be operated using the identification number. This is the point. In other words, even if you shoplift software, you will not be able to know your ID, so it will be a great deterrent against shoplifters by posting in advance in the store that "ID will be sent only to customers who have purchased it." Can do. Therefore, in the present invention, the identification number is read by the reading means, and the identification number is transmitted to the center server only when payment is completed. Thereby, the ID corresponding to the identification number is returned from the center server.
According to this invention, by transmitting the identification number stored in the identification number storage means to the center server via the register, the center server converts the received identification number into the corresponding ID and returns it to the register. This makes it impossible to know the ID in advance, which is a great deterrent for shoplifting.
According to a second aspect of the present invention, the register issues and issues the ID returned from the center server by making the visible image visible.
Customers who purchase software usually receive the product at the cash register. Therefore, in the present invention, a visible magnetic card that prints the ID returned from the center server on a display window, for example, on a display window by using a visual image forming means or magnetized magnetic powder, and a thermoreversible recording It is handed over so as to be visible to the customer in a state of being visually displayed on a so-called TC film made of a medium.
According to this invention, since the register returns the ID returned from the center server to the visible image by the visualizing means and issues it, the customer who purchased the software can accurately identify the ID when using it on the PC. It becomes possible to input.

Claim 3 is an anti-theft system for preventing unauthorized storage of a storage medium storing software from within a sales facility, the identification number storage means storing the software identification number, and stored in the identification number storage means A reading means for reading the identification number, a register having a communication function, the presence / absence of settlement of the product price and the identification number read by the reading means, and the ID corresponding to the identification number transmitted from the register A center server for transmitting to the register; and a visualizing means for visualizing the ID; and transmitting the identification number stored in the identification number storage means to the center server via the register. Thus, the center server converts the received identification number into a corresponding ID, encrypts the ID, and returns it to the register.
In the system of the present invention, the identification number read from the identification number storage means itself has no special meaning to the purchaser and may be known to others. However, if the ID returned from the center server is known by a purchaser other than the purchaser, inconvenience may occur. Therefore, in the present invention, the ID returned from the center server to the register is encrypted so that the legitimate ID cannot be decrypted even if the ID is stolen from the communication line.
According to this invention, by transmitting the identification number stored in the identification number storage means to the center server via the register, the center server converts the received identification number into the corresponding ID, encrypts it, and stores it in the register. Since it is returned, it is impossible to decipher the regular ID even if the ID is stolen from the communication line, and the confidentiality of the ID can be increased.
According to a fourth aspect of the present invention, the register decrypts the encrypted ID returned from the center server, visualizes it by the visualizing means, and issues it.
In each register, an encryption key for decrypting the encryption is set in advance. Accordingly, by decrypting the encrypted ID returned from the center server based on the encryption key, it can be issued as a human-recognizable ID.
According to this invention, the register decrypts the encrypted ID returned from the center server, visualizes it with the visualizing means, and issues it, so that it can be received as a human-recognizable ID.

Claim 5 is a theft prevention system for preventing unauthorized removal of a storage medium storing software from within a sales facility, the identification number storage means storing the software identification number, and stored in the identification number storage means A reading means for reading the identification number, a register having a communication function, the presence / absence of settlement of the product price and the identification number read by the reading means, and the ID corresponding to the identification number transmitted from the register A center server for transmitting to the register, and a visualizing means for visualizing the ID, and encrypting the identification number stored in the identification number storage means to the center server via the register By transmitting, the center server decrypts the received identification number and converts it into a corresponding ID, and then encrypts the ID and returns it to the register And it features.
In the system of the present invention, the identification number read from the identification number storage means itself does not have a special meaning, but this identification number can also be encrypted and transmitted to the center server for further confidentiality. Conceivable. Therefore, in the present invention, the identification number transmitted from the register to the center server and the ID returned from the center server to the register are encrypted so that the legitimate ID cannot be decoded even if the identification number and the ID are stolen from the communication line. Is.
According to this invention, by encrypting the identification number stored in the identification number storage means and transmitting it to the center server via the register, the center server decrypts the received identification number and converts it into a corresponding ID. Since this ID is encrypted and returned to the POS register, even if the identification number or ID is stolen from the communication line, it is impossible to decipher the legitimate ID, thereby further increasing the confidentiality of the ID. it can.
According to a sixth aspect of the present invention, the register decrypts the encrypted ID sent back from the center server, visualizes it with the visualizing means, and issues it.
According to this invention, there exists an effect similar to Claim 4.

According to a seventh aspect of the present invention, the identification number storage means further includes storage means for storing other information, and the storage means stores the identification number stored in the identification number storage means or the encrypted identification number in the register. When transmitting to the center server via the network, information to that effect is stored when the payment has been completed.
The system of the present invention essentially increases the deterrence of shoplifting by notifying shoplifters in advance that the software cannot be used even after shoplifting. However, the possibility of shoplifting is not zero. Therefore, in the present invention, when the software without the record is taken out by leaving a record of the payment in the identification number storage means of the software for which the price has been paid, it is detected at the gate equipped with the alarm system. Is.
According to this invention, when the storage means transmits the identification number stored in the identification number storage means or the encrypted identification number to the center server via the register, it is confirmed that the price has been paid, Since the information that has been paid is stored, when the software without the record is taken out, it can be detected at the gate.
According to an eighth aspect of the present invention, when the center server recognizes that the storage medium is a returned storage medium, the ID of the storage medium is changed to a different ID.
Basically, once purchased software cannot be returned. The reason is that it is necessary to prevent buyers from returning after copying. However, from the purchaser's standpoint, there is a case where it is unavoidable to replace the purchased software with other software without opening it. In such a case, the center server changes the ID so that the same ID cannot be used by notifying the center server that the product has been returned once unopened. Thereby, it is possible to prevent the ID once known by the customer from being illegally used again.
According to this invention, when the center server recognizes that the storage medium is the returned storage medium, the center server changes the ID of the storage medium to a different ID, so that the returned software ID is illegally used again. This can be prevented.
According to a ninth aspect of the present invention, the register prints the ID returned from the center server on the receipt.
Customers who have purchased software usually receive a receipt for the product at the cash register. Therefore, in the present invention, the ID returned from the center server is printed on a receipt and handed to the customer.
According to this invention, since the register prints the ID returned from the center server on the receipt, it is not necessary to separately provide a means for visualizing the ID that is surely delivered to the customer who purchased the software.

As described above, according to the first aspect of the present invention, by transmitting the identification number stored in the identification number storage means to the center server via the register, the center server converts the received identification number into a corresponding ID. Since it is sent back to the register, confidentiality is increased, and it becomes impossible to know the ID in advance, which is a great deterrent against shoplifting.
Further, in claim 2, since the register issues and visualizes the ID returned from the center server by the visualizing means, the customer who purchases the software correctly assigns the ID when using it on the PC. It becomes possible to input.
Further, in claim 3, by transmitting the identification number stored in the identification number storage means to the center server via the register, the center server converts the received identification number into a corresponding ID, encrypts it, and stores it in the register. Since it is returned, it becomes impossible to decipher the regular ID even if the ID is stolen from the communication line, and the confidentiality of the ID can be increased.
According to the fourth aspect of the present invention, since the register decrypts the encrypted ID returned from the center server and visualizes and issues it by the visualizing means, it can be received as a human-recognizable ID.
Further, in claim 5, by encrypting the identification number stored in the identification number storage means and transmitting it to the center server via the register, the center server decrypts the received identification number and converts it into a corresponding ID. Since this ID is encrypted and returned to the POS register, even if the identification number or ID is stolen from the communication line, it is impossible to decipher the legitimate ID, thereby further increasing the confidentiality of the ID. it can.
Further, in the sixth aspect, the same effect as in the fourth aspect is obtained.
Further, in claim 7, when the storage means transmits the identification number stored in the identification number storage means or the encrypted identification number to the center server via the register, it is confirmed that the price has been paid, Since the information that has been paid is stored, when the software without the record is taken out, it can be detected at the gate.
Further, in claim 8, when the center server recognizes that the storage medium is the returned storage medium, the ID of the storage medium is changed to a different ID, so that the returned software ID is illegally used again. This can be prevented.
Further, since the register prints the ID returned from the center server on the receipt, the register is surely handed to the customer who purchased the software, and there is no need to provide a means for visualizing the ID.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. .
FIG. 1A is a block diagram showing a configuration of an antitheft system according to an embodiment of the present invention, and FIG. 1B is a diagram showing an example of a package 2 to which an RFID tag 7 is attached. In this embodiment, a retail store that stores a storage medium storing software in a package and sells it as a product will be described as an example of a sales facility. Hereinafter, software refers to application software that is installed in a memory such as a PC and operates the PC, storage medium refers to a storage medium that stores the application software, and package refers to a container that stores the storage medium. Point to.
The anti-theft system 100 includes a display shelf 1 installed in a store and displaying a plurality of packages, and a package with an RFID tag (identification number storage means) 7 displayed on the display shelf 1 and storing software identification numbers. (Product) 2, a POS (Point Of Sale) register (register) 3 that has a communication function and settles a product price, a reader / writer (reading means) 4 that reads an identification number stored in the RFID tag 7, A center server 6 that manages the identification number transmitted from the POS register 3 and transmits an ID corresponding to the identification number to the POS register 3, and a printer that prints the returned ID on recording paper and converts it into a visible image (Visible image forming means) 9. The RFID tag 7 may be attached anywhere on the package 2 or on a storage medium stored in the package 2. The POS register 3 is connected to the center server 6 via the network 5. The identification number storage means may be a method of printing the identification number with a bar code, a method of recording the identification number on a magnetic card, or a method of recognizing the printed identification number. The visible image forming means 9 is not only a printer using ink or toner, but also a visible magnetic card that records information on a display window as magnetized magnetic powder, a so-called TC film made of a thermoreversible recording medium, and the like. I do not care.

Next, the schematic operation of this embodiment will be described. A customer (not shown) searches the display shelf 1 for software desired to be purchased, and brings the package (product) 2 to the cash register 8. The store clerk holds the reader / writer 4 over the RFID tag 7 on the package 2 brought by the customer. The reader / writer 4 reads the identification number stored in the RFID tag 7 attached to the package 2 and stores it in a memory (not shown) of the reader / writer 4. When the customer pays the fee, the store clerk presses a settlement button (not shown) of the POS register 3 to transmit the identification number to the center server 6 via the network 5. The center server 6 searches for a regular ID corresponding to the identification number and returns the searched ID to the POS register 3 via the network 5. In the POS register 3, the received ID is printed on a receipt together with the payment amount by the printer 9 and handed to the customer. After returning home, the customer can activate the purchased software by inputting the ID printed on the receipt into the PC.
As described above, the greatest feature of this embodiment is that the identification number stored in the RFID tag 7 is not the ID of the software, and the software cannot be activated using the identification number. In other words, since ID cannot be known even after shoplifting the software, shoplifting is done for those who plan shoplifting by posting in the store in advance "ID will be notified only to customers who have purchased the ID." Even so, it is recognized that software cannot be used, and is a great deterrent against shoplifting.

  FIG. 2 is a functional block diagram for explaining the anti-theft system according to the first embodiment of the present invention. The same components will be described with the same reference numerals. In the present embodiment, it is assumed that the RFID tag 7 attached to the package 2 stores, for example, “12345” as an identification number. A customer (not shown) searches the display shelf 1 for desired software and brings the package 2 to the cash register 8. The store clerk holds the package 2 brought by the customer over the reader / writer 4. The reader / writer 4 reads the identification number “12345” stored in the RFID tag 7 attached to the package 2 and temporarily stores it in a memory (not shown) of the reader / writer 4. When the customer pays the fee, the store clerk presses a button (for example, a settlement button) (not shown) of the POS register 3 to transmit the identification number “12345” stored in the memory to the center server 6 via the network 5. To do. In the center server 6, the control unit 24 searches the regular ID “ABCDE” corresponding to the identification number “12345”, converts it by the conversion unit 21, and converts the ID “ABCDE” converted to the POS register 3 via the network 5 Will be returned. In the POS register 3, the received ID “ABCDE” is printed on the receipt 22 together with the payment amount by the printer 9 and handed to the customer. After returning home, the customer can activate the purchased software by inputting the ID “ABCDE” printed on the receipt 22.

FIG. 3 is a functional block diagram for explaining a theft prevention system according to the second embodiment of the present invention. The same components will be described with the same reference numerals. In the present embodiment, it is assumed that, for example, the identification number “12345” is stored in the RFID tag 7 attached to the package 2. A customer (not shown) searches the display shelf 1 for desired software and brings the package 2 to the cash register 8. The store clerk holds the package 2 brought by the customer over the reader / writer 4. The reader / writer 4 reads the identification number “12345” stored in the RFID tag 7 attached to the package 2 and temporarily stores it in a memory (not shown) of the reader / writer 4. When the customer pays the fee, the store clerk pushes a button (not shown) (not shown) of the POS register 3 to transmit the identification number “12345” stored in the memory to the center server 6 via the network 5. To do. In the center server 6, the control unit 24 searches for a regular ID “ABCDE” corresponding to the identification number “12345”, converts it with the conversion unit 21, and further encrypts it with, for example, “YYYYY” by the encryption unit 27. Return to the POS register 3 via the network 5. In the POS register 3, the received encrypted ID “YYYYY” is decrypted by the decryption unit 29 into the original ID “ABCDE”, and the printer 9 prints the ID “ABCDE” on the receipt 22 together with the settlement amount to the customer. Hand it over. After returning home, the customer can activate the purchased software by inputting the ID “ABCDE” printed on the receipt 22. Note that the composite unit 29 may be included in the POS register 3.
Thus, in the system of the present embodiment, the identification number “12345” read from the RFID tag 7 has no particular meaning. However, the ID “ABCDE” returned from the center server 6 may be inconvenient if it is known to anyone other than the purchaser. Therefore, the ID returned from the center server 6 to the POS register 3 is encrypted as “YYYYY” so that the legitimate ID cannot be decrypted even if the ID is stolen from the communication line. The POS register 3 is preliminarily delivered with an encryption key for decrypting the encryption. Therefore, by decrypting the encrypted ID “YYYYY” returned from the center server 6 based on this encryption key, it can be issued as an ID “ABCDE” that can be recognized by humans.

FIG. 4 is a functional block diagram illustrating the anti-theft system according to the third embodiment of the present invention. The same components will be described with the same reference numerals. In the present embodiment, it is assumed that, for example, the identification number “12345” is stored in the RFID tag 7 attached to the package 2. A customer (not shown) searches the display shelf 1 for desired software and brings the package 2 to the cash register 8. When the store clerk holds the package 2 brought by the customer over the reader / writer 4, the reader / writer 4 reads the identification number “12345” stored in the RFID tag 7 attached to the package 2 and temporarily stores it in a memory (not shown) of the reader / writer 4. Remember. When the customer pays the fee, the store clerk presses a button (not shown) of the POS register 3 (for example, a settlement button) to read the identification number “12345” stored in the memory. Encrypted to “XXXX” and transmitted to the center server 6 via the network 5. In the center server 6, the control unit 24 decrypts the encrypted identification number “XXXX” into the original identification number “12345” by the decryption unit 25, and the regular ID “ABCDE” corresponding to the identification number “12345”. ”And converted by the conversion unit 26, and further encrypted by the encryption unit 27, for example,“ YYYYY ”, and returned to the POS register 3 via the network 5. In the POS register 3, the received encrypted ID “YYYYY” is decrypted by the decryption unit 29 into the original ID “ABCDE”, and the printer 9 prints the ID “ABCDE” on the receipt 22 together with the settlement amount to the customer. Hand it over. After returning home, the customer can activate the purchased software by inputting the ID “ABCDE” printed on the receipt 22.
Note that the center server 6 may omit the decryption unit 25 and convert from “XXXX” encrypted by the encryption unit 23 to the regular ID “ABCDE”. Further, the encryption unit 23 and the decryption unit 29 may be included in the POS register 3.
As described above, in the system of the present embodiment, the identification number “12345” read from the RFID tag 7 has no particular meaning, but this identification number is also encrypted as “XXXX” in order to further improve confidentiality. Transmission to the server 6 can be considered. Therefore, even if the identification number “12345” transmitted from the POS register 3 to the center server 6 and the ID “ABCDE” returned from the center server 6 to the POS register 3 are encrypted, the identification number and the ID are stolen from the communication line. It prevents the legitimate ID from being deciphered.

  FIG. 5 is a flowchart explaining mainly the operation of the customer in the store when the anti-theft gate is not installed at the exit of the store in the anti-theft system of the present invention. A description will be given with reference to FIG. First, the customer searches for the desired software from the display shelf 1, and brings the package (product) 2 storing the software to the cash register 8 (S1). The store clerk holds the package 2 brought by the customer over the reader / writer 4 (S2). Here, it is checked whether or not the identification number read by the reader / writer 4 is a regular identification number managed in the store (S3). This check operation detects a case where the information of the RFID tag 7 attached to the package 2 has not been read accurately for some reason, and may be checked by the center server 6. As a result of this check, if it is not a regular identification number (NO route in S3), that fact is displayed and replaced with another package (S11). If it is a legitimate identification number in step S3 (YES route in S3), the software costs are summed by the POS register 3 (S4), and all the sums are finished (YES route in S5). (S6: YES route), the store clerk presses a “settled button” (not shown) in the POS register 3 (S7), and the identification number is transmitted to the center server 6 via the network 5 (S7). S8). The center server 6 searches for a regular ID corresponding to the identification number and returns the searched ID to the POS register 3 via the network 5. In the POS register 3, the received ID is printed on the receipt together with the payment amount by the printer 9 (S9), and the receipt is handed over to the customer (S10). After returning home, the customer can activate the purchased software by entering the ID printed on the receipt.

  FIG. 6 is a flow chart for explaining mainly the operation of the customer in the store when the anti-theft gate is installed at the exit of the store in the anti-theft system of the present invention. A description will be given with reference to FIG. First, the customer searches the display shelf 1 for desired software and brings the package (product) 2 to the cash register 8 (S21). The store clerk holds the package 2 brought by the customer over the reader / writer 4 (S22). Here, it is checked whether or not the identification number read by the reader / writer 4 is a regular identification number managed in the store (S23). This check operation detects a case where the information of the RFID tag 7 attached to the package 2 has not been read accurately for some reason, and may be checked by the center server 6. As a result of this check, if it is not a regular identification number (NO route in S23), it is displayed and switched to another package (S34). If it is a regular identification number in step S23 (YES route in S23), the software charges are summed by the POS register 3 (S24), and all the sums are finished (YES route in S25), and the total fee is charged. When the payment is completed (YES in S26), the store clerk presses a “payment completed button” (not shown) of the POS register 3 (S27), and puts the payment mark on the RFID tag attached to the paid package. Record (S28). The identification number is transmitted to the center server 6 via the network 5 (S29). The center server 6 searches for a regular ID corresponding to the identification number and returns the searched ID to the POS register 3 via the network 5. In the POS register 3, the received ID is printed on the receipt together with the settlement amount by the printer 9 (S30), and the receipt is handed over to the customer (S31). When the customer arrives at the gate with the package received (S32), it is checked whether or not a payment mark is stored in the RFID tag of the package (S33), and if the payment mark is stored (S33). The customer can pass through the gate (S36), and after returning home, the customer can activate the purchased software by entering the ID printed on the receipt. If the paid mark is not stored in step S33 (NO route in S33), a warning sound is emitted and the clerk is notified (S35). In this case, the shoplifter is not informed of the ID, so the software cannot be started.

In this way, the system of the present invention essentially increases the deterrence of shoplifting by notifying shoplifters in advance that the software cannot be used even if shoplifting. However, the possibility of shoplifting is not zero. Therefore, in the present embodiment, by leaving a record of the paid price in the RFID tag of the software for which the price has been paid, when the software without the record is taken out, it is detected at the gate.
Basically, once purchased software cannot be returned. The reason is to prevent being returned after being copied. However, it may happen that you want to replace it with other software that has not been opened. In such a case, the center server 6 changes the ID so that the same ID cannot be used by notifying the center server 6 from the POS register 3 that the product has been returned once. Thereby, it is possible to prevent the ID once known by the customer from being illegally used again.
