Description

  The present invention relates to a system and method for managing an IC card used for a passenger transport ticket or the like.

  As a system for managing IC cards typified by train IC regular tickets, IC card information is read by a terminal (for example, an automatic ticket gate) and the read information is collected on a management server via a network. It has been.

  In such a management system, card information transmitted from each user terminal is temporarily stored in a management server, and an illegal card such as a counterfeit IC card is detected at night based on the stored card information ( For example, see Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-232727

  However, in the method as disclosed in Patent Document 1, since the detection processing of fraudulent cards is performed collectively at night, for example, when a fraudulent card is used during the day, the fraudulent card is not detected until it is nighttime. become. As described above, if it takes time to detect a fraudulent card, there is a risk that damage (for example, monetary damage) resulting from the use of the fraudulent card may increase.

  Further, when collection of card information is delayed due to a failure of a use terminal or the like, an illegal card detection process is performed after waiting for arrival of the delayed card information. Therefore, the detection of a fraudulent card may become slower, and the damage caused by the use of the fraudulent card may be further increased.

  An object of the present invention is to realize an IC card management system and a management method that are more suitable for detecting the use of an unauthorized card at an early stage.

  In order to solve the above problems, an IC card management system according to the present invention includes a use terminal that reads card information stored in an IC card, and a management device that accumulates card information transmitted from the use terminal. A fraud detection device is provided that detects a fraud card based on the transmitted card information and the card information stored in the management device each time the card information is transmitted.

  According to this, when a fraudulent card is used at a use terminal, the fraud card is detected each time card information is transmitted from the use terminal. In other words, even before the management server has all the card information, the illegal card detection process is executed based on the collected card information. Thereby, since the time interval for detecting a fraudulent card can be shortened, a fraudulent card can be found early.

  In this case, it is possible to install a notification unit that notifies the user terminal of information on the fraud card detected by the fraud detection device. As a result, it becomes possible to quickly stop the use of the fraud card at the use terminal, and the use of the fraud card is prevented at an early stage, so that the expansion of damage caused by the fraud card can be further suppressed.

  Further, when detecting a fraudulent card, it is preferable to detect a fraudulent card by analyzing the use history of the IC card, in addition to detecting it by collating with card ID data stored in advance. Thereby, even if the card ID of the IC card is registered, if the IC card usage history is unnatural, it can be determined that the IC card is an illegal card. Become more accurate.

  In addition, the IC card management system of the present invention includes a management device that accumulates card information transmitted from a user terminal capable of reading card information recorded on the IC card, and each time card information is transmitted from the user terminal. A fraud detection device that detects a fraud card based on the transmitted card information and the card information stored in the management device can be provided.

  The IC card management method of the present invention comprises a step of reading card information stored in an IC card by a use terminal, and a step of storing card information transmitted from the use terminal in the management device. A fraud detection step of detecting a fraudulent card based on the transmitted card information and the card information stored in the management device each time information is transmitted.

  ADVANTAGE OF THE INVENTION According to this invention, the management system and management method of a more suitable IC card can be implement | achieved by discovering use of an unauthorized card at an early stage.

  An embodiment of an IC card management system to which the present invention is applied will be described with reference to the drawings. FIG. 1 is a configuration diagram of an IC card management system according to the present embodiment.

  As shown in FIG. 1, the IC card management system includes a plurality of automatic ticket gates 10a and 10b serving as terminals for reading card information of IC cards represented by train IC regular tickets, and these automatic ticket gates 10a. ID management device 14 as a management device for storing card information transmitted from 10b.

  Here, the IC card management system according to the present invention is based on the transmitted card information and the card information stored in the ID management device 14 each time the card information is transmitted from each of the automatic ticket gates 10a and 10b. A fraud check device 16 is provided on the same day as a fraud detection device that analyzes a card usage history and detects a fraud card.

  The IC card management system will be described in more detail. The IC card is equipped with an IC chip in which a card ID and card usage information are stored so as to be rewritable. Note that a thermochromic layer capable of printing or erasing characters by temperature change may be laminated on the surface of the IC card, or a personal authentication function using biometric information such as fingerprints may be mounted.

  The automatic ticket gate 10a reads the card information from the IC card in a non-contact type or a contact type, and creates usage information 20 based on the read card information. The usage information 20 here includes a card ID, a usage station name, a usage date, a usage identification number (hereinafter referred to as a serial number), a charge balance, commuter pass information, and the like. More specifically, the automatic ticket gate 10a counts up the serial number in the card information read from the IC card, and creates the usage information 20 by assigning the used station name to the counted serial number. The created usage information is transmitted to the ID management device 14 via the network. In addition, a stop function for stopping the use of an unauthorized card is implemented based on the unauthorized card information 23 transmitted from the ID management device 14. The same applies to the automatic ticket gate 10b.

  The ID management device 14 includes a usage information receiving unit 24 that receives usage information 20 transmitted from the automatic ticket gates 10a and 10b at set time intervals (for example, every 30 minutes), and a usage information output from the usage information receiving unit 24. A fraudulent card check unit 22 that discriminates fraudulent cards at night based on the information 20, and fraudulent card information that distributes fraudulent card information that is a detection result of the night fraud card check unit 22 to the automatic ticket gates 10a, 10b and automatic ticketing terminals. A batch distribution unit 25 and a transmission unit 26 that transfers the usage information 20 output from the usage information receiving unit 24 and the fraud card information output from the nighttime fraud card check unit 22 to the fraud check device 16 on the same day are provided. Further, a receiving unit 28 that receives fraud card information from the fraud check device 16 on the same day, and a fraud card information emergency distribution unit 30 that quickly transmits the fraud card information output from the receiving unit 28 to the automatic ticket gates 10a and 10b. I have. The nightly illegal card check unit 22 stores the usage information 20 output from the usage information receiving unit 24, sorts the stored usage information 20 in order of serial number for each IC card, and then stores the usage information 20 in the usage information 20. Based on this, the illegal card detection process is executed at night, for example. The nighttime illegal card check unit 22 includes a registered card ID storage unit that holds a card ID database.

  The same day fraud check device 16 receives the card information receiving unit 32 that receives the usage information 20 and necessary card information (for example, past usage information and card ID database) from the ID management device 14 and the fraud card information from the ID management device 14. A fraudulent card information receiving unit 34 for receiving, a fraudulent card checking unit 18 for immediately discriminating a fraudulent card based on output information of the card information receiving unit 32 and the fraudulent card information receiving unit 34 (for example, daytime), and a fraudulent card for the same day An unauthorized card information transmitting unit 36 is provided as a notifying unit that quickly transfers the unauthorized card information output from the check unit 18 to the ID management device 14.

  The same day fraud card check unit 18 includes a card information determination unit 38, a fraud card information storage unit 41, and a same day fraud card check control unit 40 that outputs a control command to the card information determination unit 38 and the fraud card information storage unit 41. ing. Each time the usage information 20 is received by the card information reception unit 32, the card information determination unit 38 determines an unauthorized card based on the usage information 20 in accordance with the control command. More specifically, each time the usage information 20 is output from the card information receiving unit 32, the card information determination unit 38 checks the usage information 20 against the registered ID database held in the ID management device 14 and uses the usage information 20. By analyzing the usage history of the IC card based on the information 20, an unauthorized card is determined based on the usage information 20. The unauthorized card information storage unit 41 stores the unauthorized card information that is the determination result of the card information determination unit 38.

  A basic operation of the IC card management system configured as described above will be described. When the user brings his IC card close to the automatic ticket gate 10a, for example, the card information of the IC card is created as usage information 20 after being read by the automatic ticket gate 10a. The created usage information 20 is transmitted to the ID management device 14 via a network at set time intervals (for example, every 30 minutes). The transmitted usage information 20 is stored in the ID management device 14 and output to the fraud check device 16 on the same day. Each time the usage information 20 is output to the same day fraud check device 16, the fraud card is discriminated by the same day fraud check device 16 based on the outputted usage information 20. The information on the determined fraud card is sent from the fraud check device 16 to the automatic ticket gates 10a and 10b via the ID management device 14 on the same day. The use of the IC card corresponding to the transmitted illegal card information is immediately stopped by the automatic ticket gates 10a and 10b.

  Further, at night, an unauthorized card is determined based on the usage information 20 stored in the ID management device 14. The determined unauthorized card information is transmitted from the ID management device 14 to the automatic ticket gates 10a and 10b. The use of the IC card corresponding to the transmitted illegal card information is stopped by the automatic ticket gates 10a and 10b.

  FIG. 2 is a flowchart showing the entire process of checking the unauthorized card on the same day. As shown in FIG. 2, when the IC card is read by the automatic ticket checker 10a, usage information 20 is created by the automatic ticket checker 10a based on the read card information (S100). The created usage information 20 is received by the usage information receiving unit 24 via the network (S101). Further, the illegal card information and necessary card information (for example, past usage information, card ID database) stored in the night illegal card check unit 22 are read (S102). The usage information 20 of the process of S101 and the unauthorized card information and the necessary card information of the process of S102 are transmitted by the transmission unit 26 (S103).

  The usage information 20 and necessary card information transmitted in step S103 are received as card information by the card information receiving unit 32 (S104). Further, the unauthorized card information is received by the unauthorized card information receiving unit 34 (S105). The card information received in the step S104 and the illegal card information received in the step S105 are input to the illegal card check control unit 40 on the same day (S106). Based on the input card information, a new illegal card is determined by the card information determination unit 38 (S107). More specifically, it is determined whether or not the card ID in the card information is registered in the card ID database included in the necessary card information. If it is not registered, the IC card is determined as an unauthorized card. Even when registered, the IC card usage history is analyzed based on the card information. When the usage history is unnatural as a result of the analysis, the IC card is determined as an unauthorized card.

  The newly determined fraud card information is integrated with the fraud card information input in step S106, and then stored as the fraud card information 23 in the fraud card information storage unit 41 (S108). The stored unauthorized card information 23 is transmitted by the unauthorized card information transmitting unit 36 in response to a command from the unauthorized card check control unit 40 on the same day (S109).

  The unauthorized card information 23 transmitted in step S109 is received by the receiving unit 28 (S110). The received unauthorized card information 23 is distributed by the unauthorized card information emergency distribution unit 30 (S111). The distributed illegal card information 23 is received by the automatic ticket gates 10a and 10b via the network (S112). Based on the illegal card information 23 received in this manner, the use of the illegal IC card is stopped by the automatic ticket gates 10a and 10b.

  In short, as shown in FIG. 2, the step (S100) of reading the card information stored in the IC card by the automatic ticket gates 10a and 10b, and the usage information 20 transmitted from the automatic ticket gates 10a and 10b are used as the ID management device 14. Each time the usage information 20 is transmitted from the automatic ticket gates 10a and 10b, an illegal operation is performed based on the transmitted usage information 20 and the card information stored in the ID management device 14. The same day fraud detection step (S106) for detecting a card is included.

  According to the IC card management system of this embodiment, each time the usage information 20 is transmitted from each of the automatic ticket gates 10a and 10b, the fraud card detection process is performed on the same day. In other words, the illegal card detection process is executed based on the collected usage information 20 even before all the usage information 20 is collected. Thereby, since the time interval for detecting a fraudulent card can be shortened, a fraudulent card can be found early.

  Further, the unauthorized card information is promptly notified to the automatic ticket gates 10a and 10b by the unauthorized card information transmission unit 36 and the unauthorized card information emergency distribution unit 30. As a result, it becomes possible to quickly stop the use of the illegal card by the automatic ticket gates 10a and 10b, and the use of the illegal card is prevented at an early stage, so that the expansion of damage caused by the illegal card can be further suppressed. In short, since illegal use of an IC card can be stopped at an early stage, it is possible to improve the profits of transportation operators and the like.

  Further, when detecting a fraudulent card, it is preferable to detect a fraudulent card by analyzing the use history of the IC card, in addition to detecting it by collating with card ID data stored in advance. Thereby, even if the card ID of the IC card is registered, if the IC card usage history is unnatural, it can be determined that the IC card is an illegal card. Become more accurate.

  Further, for example, even when the automatic ticket gate 10b breaks down, an illegal card detection process is executed based on the card information collected from the automatic ticket gate 10a. Thereby, the time interval which detects use of an unauthorized card can be shortened more.

  Here, it supplements about the illegal card discrimination | determination process of the illegal card check part 18 and the night illegal card check part 22 on the same day.

  FIG. 3 is a flowchart showing a detailed processing procedure for determining an unauthorized card by the unauthorized card check unit 18 on the same day. This processing is performed by comparing the IC card usage information 20 with the necessary card information in the ID management device 14 every time the IC card usage information 20 is input to the unauthorized card check unit 18 on the same day. This is processing for analyzing an IC card usage history and detecting an unauthorized card.

  For example, when the fraudulent card checking unit 18 receives the usage information 20 and the necessary card information (for example, past usage information, card ID database) from the card information receiving unit 32, the card ID of the usage information 20 is stored in the card ID database. Verification is performed (S200). If the card ID is not registered in the card ID database, the IC card corresponding to the card ID is registered as an unauthorized card (S201).

  When registered in the card ID database, the serial number of the usage information 20 is verified. For example, by comparing and referring to the serial number of the usage information 20 and the serial number in the past usage information, it is determined whether a large number of serial numbers of the usage information 20 are missing (S202). If there is a large number of missing serial numbers, the IC card corresponding to the usage information 20 is registered as an unauthorized card (S201).

  If there are no missing serial numbers, it is determined whether there are duplicate serial numbers (S203). If there is a duplicate serial number, the IC card corresponding to the usage information 20 is registered as an unauthorized card (S201). That is, since the serial number is incremented by one every time the automatic ticket gates 10a and 10b are used, if there is a large number of missing or duplicated numbers, it is assumed that the card is an illegal card.

  When there is no duplicate serial number, the usage form in the usage information 20 is determined (S204). For example, it is determined whether or not the cumulative erasure count of the information stored in the usage information 20 is not unnatural. If the usage form is unnatural, the IC card corresponding to the usage information 20 is registered as an unauthorized card (S201).

  When it is determined that the usage form of the usage information 20 is natural, it is determined whether or not the serial number is continuous information (S205). When the serial numbers are discontinuous, for example, it is determined that usage information has not been acquired due to a failure of one of the automatic ticket gates 10a and 10b, and the fraud card determination process ends.

  When the serial numbers are consecutive, the process of increasing the charge balance of the usage information 20 is determined (S206). For example, when the increase history is unnatural, for example, when the charge balance increases rapidly and repeatedly, the IC card corresponding to the usage information 20 is registered as an unauthorized card (S201).

  When the process of increasing the charge balance is normal, the rewrite history of the commuter pass information of the usage information 20 is checked (S207). For example, when the rewritable history is unnatural, for example, the commuter pass information is rewritten repeatedly in a short time, the IC card corresponding to the usage information 20 is registered as an unauthorized card (S201).

  When the rewrite history of commuter pass information is normal, the IC card is authorized as a valid card by completing the fraudulent card discrimination process. Note that the information on the unauthorized card registered in the process of S201 is stored in the unauthorized card information storage unit 41.

  FIG. 4 is a flowchart showing a detailed processing procedure for determining a fraudulent card by the nightly fraud card check unit 22. This process is a process executed at night, and after the usage information 20 accumulated in the nighttime illegal card check unit 22 is rearranged in order of usage details (for example, in the order of serial numbers) on a card basis, This is a process for detecting a fraudulent card by analyzing the history and determining the consistency of the usage details.

  As shown in FIG. 4, this process is basically the same as the fraud card determination process of FIG. 3, but before the card ID determination process (S200) is started, the usage information 20 rearrangement process (S300). The serial number continuity determination process (S205) is not performed, and the data correction process (S301) is performed after the commuter pass information illegal rewrite determination process (S207). Different from case 3.

  In the process of S300, the usage information 20 accumulated in the nighttime illegal card check unit 22 is rearranged in the order of serial numbers. The usage information 20 accumulated here is all usage information related to each IC card used on that day. The rearranged usage information 20 is subjected to determination processing in step S202. In step S301, if the IC card is determined to be normal in step S207, the data loss is automatically corrected when the IC card usage information 20 has a data loss within an allowable range.

  Although the present invention has been described above with the embodiments, it is not limited thereto. In short, the usage information for each IC card may be centrally managed, and the usage information 20 transmitted from the automatic ticket gates 10a and 10b may be checked for fraud on the same day.

  The present invention is not limited to an IC commuter pass but can be applied to managing various forms of IC cards such as passenger transport tickets and electronic money cards. Moreover, although the example which divided | segmented and implement | achieved ID management apparatus 14 and the same day fraud check apparatus 16 in another computer was demonstrated, it can also be mounted in the same computer.
