Description

The present invention relates to various card systems using a storage medium such as an IC card, and relates to a method of creating and managing a card usage device usage history by each card user.
In particular, use characteristics analysis of each user's card when an unspecified number of users use card-equipped devices placed in a wide area, such as a membership card, credit card, or transportation ticket, The present invention relates to a method of constructing the use history of each card as accurate time-series data in order to eliminate invalid cards and detect / suppress unauthorized use of cards.

  In a conventional wide area card system, a clock built in a use device or a clock value built in a card is used as a time stamp, and a system for constructing a use history for each card according to the time stamp is known. It is.

In a large-scale / wide-area card usage system, a system for analyzing the usage status of each user to create a new service or monitoring unauthorized use of the card is required. In order to achieve this, it is necessary to analyze the usage history for each user in detail, but for this purpose, the usage time of the card is grasped and the usage history for each card ID is correctly arranged in time series. There is a need.
However, with some exceptions such as bank online systems, all card-based devices installed throughout the country are not all managed online at the central location, and some devices are operated stand-alone. There are many. For such a stand-alone terminal, use data for a certain period is periodically transferred to a central system using a storage medium such as a disk.
Even if all card-using devices are connected online, the distribution of usage data to the center is not only performed in real time one by one, but generally, the network load is combined with batch processing. Has eased. Under such circumstances, in order to accurately construct the usage history of each user, a method of using the internal clock of the card-using device or the internal clock of the card is known, and a history creation method using these Is widely spread. However, in any of these methods, there are technical and cost issues to keep all watches distributed throughout the country accurate, and of course, if a clock goes wrong, Accurate history data cannot be created.
In this way, in a system in which all the devices used are connected online, a certain level of reliability can be ensured by regularly distributing the basic time from the center to each terminal, but most cards with a mix of stand-alone terminals In the system, since the created history data depends on the stand-alone terminal or the clock inside the card, there remains a problem that the reliability is low.
The object of the present invention is to provide means for easily building an accurate usage history for each card user without referring to the clock in the card or the clock of the device used, and to analyze the usage characteristics of the card user. To make it easier.

  In the memory of the card, 1 to n counter areas for recording the number of times the card using device is used are provided. When a card is issued, all counter values are initialized, and when the card uses a card-using device, the counter is calculated according to the attribute of the card or the device used or the usage details, and the value of each counter is updated. To do. The card use device transmits a card ID, card use information, and a counter value to the history management system according to the card use contents, and the history management system organizes the card use information for each ID. At this time, for each ID, use data is arranged in order from the smallest counter value to create accurate usage history data and compare the values of each counter to analyze the usage characteristics for each ID. carry out.

  According to the present invention, since it is possible to construct an accurate usage history for each card user without referring to any clock in the card or the clock of the card-using device, (1) history data can be easily constructed. It can be expected that (2) there will be no mistakes in the history data resulting from clock error.

Hereinafter, the contents of the invention will be described with reference to FIGS. 1 to 10 as an example of a history management system for managing customer usage of IC card tickets, which is an embodiment of the present invention.
FIG. 1 shows a configuration of an IC card ticket 1010 and a card using device 1020 used by the IC card ticket. A counter 1011 and application information 1012 are stored in the memory inside the IC card ticket. On the other hand, the card-using device has an internal clock 1021, memory, device ID 1022, card usage information 1023, device program 1024, counter calculator 1025 that controls the counter value in the IC card, and information exchange with the IC card. The card reader / writer 1026 is configured to perform. In FIG. 1, the counter calculator exists only in the card-using device, but the counter calculator is incorporated in the IC card, and the counter 1011 in the IC card is controlled by the card counter (the calculator in the card). A plurality of calculators may be provided such as a counter) and a device counter (a counter controlled by a calculator in the device).
FIG. 2 shows the position of the history management system in the entire card system. The history management system 2010 includes a basic clock 2011 indicating a reference time of the entire card system, a history management program 2012, usage data 2013 on the day, and usage history data 2014. In addition, the history management system is connected to card using devices 2030 distributed throughout the country via the communication network 2020 (some devices may be stand-alone). There are ticket issuing machines 2031, automatic ticket gates 2032, automatic checkout machines 2033, etc. as card-using devices. Each time the various devices are accessed using an IC card, the usage contents are determined, and the card Usage information is sent to the history management center via the communication network.
FIG. 3 shows the data structure of the memory in the IC card. The IC card internal memory 3000 includes a counter 3010 that stores a cumulative value of the number of times the card using device is used and application information. As application information, a customer number 3020 for identifying a card user and various ticket information 3030 such as an issue date and an expiration date are stored.
FIG. 4 shows the structure of an automatic ticket gate as an example of a card-using device. When the card user passes the ticket gate, the card user passes the IC card ticket over the IC card reading unit 4010 and passes the ticket gate. At this time, the ticket checker reads the memory of the IC card ticket, checks the expiration date of the IC card ticket, etc., and if it is determined that the ticket is invalid, closes the gate 4030 and passes the user. While blocking, the reason why the gate is closed is displayed on the display window 4040. On the other hand, if the ticket is valid, the counter value of the IC card ticket is read into the counter calculator 4020, 1 is added to the current counter value and written to the IC card, and the IC card ticket information and Based on the information of the ticket gates that the user has passed, card usage information is created and transmitted to the central history management system.
FIG. 5 shows card usage information sent from each card usage device to the history management system when the IC card ticket is input to the card usage device. The card use information 5000 includes a card use date 5010, a use time 5020, a customer ID 5030, a use device ID 5040, use information 5050, and a counter 5060.
FIG. 6 shows a procedure for creating card usage information and transmitting data by the card-using device. First, in step 6010, the card usage content is determined from the ID of the device used and the information transmitted between the card and the device. Subsequently, in step 6020, it is determined whether the usage content is content to be transmitted to the central history management system. With this step, for example, items that do not need to be managed as usage history, such as simple operation mistakes and balance inquiry, etc. Does not update the usage count, nor does it send usage details to the history management system. Subsequently, in steps 6030 and 6040, the use date and use time are set with reference to the internal clock of the card using device. Next, in step 6050, the customer ID is set with reference to the customer ID of the IC card being used. Next, in step 6060, the used device ID is set with reference to the device ID of the used device. Next, in step 6070, usage information is set, and in step 6080, a counter is set. The counter in this embodiment is set by adding 1 to the counter value of the current IC card.
The usage information for each case set as described above is transmitted to the central history management system in step 6090 by online or batch processing. Note that usage information of a card-using device that is not connected to the network is periodically registered in the history management system via a storage medium such as a magnetic disk.
FIG. 7 shows the same day usage data in which data transmitted from the card usage devices distributed throughout the country to the history management system are arranged in the order in which the data arrived. Similarly to the usage data, the data item includes a usage date 7010, a usage time 7020, a customer ID 7030, a usage device ID 7040, a counter 7050, and usage information 7060. The usage data that has been collected in a large amount every day is registered as usage history data by the history management system, which is sorted by each customer ID and in ascending order of counter.
FIG. 8 shows the data structure of the usage history for each customer ID. Usage history data is data in which the usage information of all card users' card usage devices is organized by customer ID over a certain period in the past. The data item for each customer ID for one day includes a counter 8010, a use time 8020, a use device ID 8030, and use information 8040. In the example of FIG. 8, all counter values are continuous, but in a system that collects information in real time with all the used devices connected online, it is normal that all counter values exist continuously. If there is a missing tooth in the counter, some abnormality has occurred. In this way, the state of the system can be evaluated by checking the continuity of the counter.
On the other hand, in a system where some of the devices used are stand-alone, or in which real-time processing and batch processing are mixed for information collection, there is a time lag in collecting some of the usage data. Discontinuous parts occur in the counter. In such a case, a counter is complemented at the place where the tooth is missing, and a NO-DATA flag is set 9010 for the data item. By doing this, for example, for each customer ID, it is possible to calculate the ratio of using the standalone terminal, the number of times to access the standalone terminal continuously, etc., and use this to calculate the usage characteristics for each customer ID It becomes possible to evaluate.
FIG. 10 shows an application example of usage characteristic analysis using a counter. In the examples so far, the case where one counter is uniformly added to all the devices has been described. However, by providing a plurality of counters in the card, the range of application to the usage history analysis method is expanded. For example, a counter A 10010 that adds a counter every time it is used by a counter calculator in all card-using devices, a counter B 10020 that adds a counter by a counter of a specific device, and a counter in a card that adds a counter Multiple counters such as Counter X 10030 are provided in the card memory and analyzed by the history management system in the manner described so far, for each customer ID, the ratio of using a specific device or counting with the counter in the card The ratio 10040 of the number and the number of counters by all used devices can be calculated. In this way, by applying history analysis with multiple counters, system management can easily collect various history information, such as evaluating the operating status of devices and detecting fraud due to card access to unknown devices. It becomes possible to evaluate this.

This is a configuration of an IC card ticket and a card using device used by the IC card ticket. This is the position of the history management system in the entire card system. This is the data structure of the IC card memory. It is the structure of an automatic ticket gate. This is card usage information sent from each card usage device to the history management system. This is a procedure for creating card usage information and transmitting data. Unprocessed usage data transmitted from the card usage device to the history management system. This is usage history data for each customer ID. This is usage history data for each customer ID when there is an empty counter. It is an example of analysis of usage history when a plurality of counters are prepared.
