Description

  The present invention relates to a detection device, a detection method, and a program.

  In recent years, credit cards that allow purchase of goods and the like by postpay have been widely used in electronic payments and the like.

  However, while the use of credit cards is progressing, there are many cases in which personal information recorded on a magnetic stripe of a credit card owned by another user is illegally read and the read personal information is abused.

  One example of misuse of illegally read personal information is “skimming” in which the credit card is illegally copied using personal information stolen from a credit card owned by another user.

  Skimming is performed by illegally crafting the inside of a settlement apparatus that reads personal information written on a credit card. At that time, it is necessary to open the cover of the settlement apparatus.

  In order to detect an illegal opening / closing action of the lid, it is conceivable to use a settlement apparatus having a detection mechanism for detecting the opening / closing action using a mechanical switch (mechanical contact).

  However, there is a problem that the operation to be performed by the detection mechanism can be easily invalidated by adhering the switch mechanism of the mechanical switch with an adhesive or the like while the mechanical switch is in a conductive state.

  In addition, because of the mechanical contact, the vibration propagated from the surrounding installation environment becomes disturbance noise, and there is a risk of erroneously detecting the opening / closing action of the lid in the housing.

Therefore, by attaching a three-dimensional acceleration sensor and a three-dimensional angular velocity sensor to the device, it is possible to detect that the device has moved based on the angular velocity applied in the vertical direction and the angular velocity applied in the horizontal direction detected by these sensors. . As an apparatus to which these sensors are attached, for example, there is one described in Patent Document 1.

  In the above-described technique, when the device is composed of one member, the movement of the device can be detected by attaching a sensor at an arbitrary position of the member.

  However, when the apparatus is composed of a plurality of members and the sensor is attached to only some of the members, the movement of the member to which the sensor is not attached cannot be detected. For example, in a device composed of a container having an opening and a lid that covers the opening, when the sensor is attached only to the container, an operation of opening the lid and tampering the inside of the device Cannot be detected.

  On the other hand, in a device composed of a lid and a container, if the sensor is attached only to the lid, movement of the entire device due to an earthquake or the like (not due to fraud) is also detected.

  In other words, it becomes difficult to detect that some members of the apparatus composed of a plurality of members are moved (opened / closed) in order to perform fraud as described above.

  An object of this invention is to provide the detection apparatus, the detection method, and program which solve the subject mentioned above.

  In order to solve the above-described problems, a detection device of the present invention is a detection device attached to a device having an opening and having a container for housing a component and a lid for covering the opening. A first acceleration sensor that is attached to the lid and detects a first acceleration acting on the lid in the extending direction of the predetermined axis; and is attached to the container and acts on the container in the extending direction of the predetermined axis. When the second acceleration sensor that detects the second acceleration, the comparison unit that compares the first acceleration and the second acceleration, and the comparison result show that the first acceleration and the second acceleration are different, An open detection unit that outputs an open detection signal indicating that the lid is opened.

  In order to solve the above-described problems, a detection method of the present invention detects an opening of a lid in an apparatus having an opening, a container for housing a component, and a lid for covering the opening. A first acceleration acting on the lid in the extending direction of a predetermined axis detected by the first acceleration sensor attached to the lid, and a second acceleration sensor attached to the container. If the process comparing the second acceleration acting on the container in the extending direction of the predetermined axis and the comparison result show that the first acceleration and the second acceleration are different, it indicates that the lid is opened. Open detection processing for outputting an open detection signal.

  Also, a program to be executed by a computer, attached to the lid on a detection device attached to a device having an opening and containing a container and a lid for covering the opening The first acceleration acting on the lid in the extending direction of the predetermined axis detected by the detected first acceleration, and acting on the container in the extending direction of the predetermined axis detected by the second acceleration sensor attached to the container. And a release detection procedure for outputting an opening detection signal indicating that the lid is opened when the first acceleration and the second acceleration are different from each other as a result of the comparison. Let

  According to the present invention, in an apparatus having an opening and containing a component and a lid for covering the opening, an extension of a predetermined axis detected by a first acceleration sensor attached to the lid The first acceleration acting on the lid in the direction is compared with the second acceleration acting on the housing in the extending direction of the predetermined axis detected by the second acceleration sensor attached to the housing. When the second acceleration is different from the second acceleration, an opening detection signal indicating that the lid is opened is output.

  Because of this configuration, even when the device is composed of a plurality of members whose positions change relative to each other, changes in the relative positions of the members can be detected. It is possible to detect movements that are crafted.

  Hereinafter, a detection device (including a detection method and a program) according to an embodiment of the present invention will be described.

  The following example demonstrates the case where the detection apparatus of this invention is attached to the payment apparatus which comprises the payment system which performs payment using a credit card. Moreover, you may attach the detection apparatus of this invention to ATM (Automated-Teller Machine; automatic cash dispenser), a vending machine, etc., for example.

  First, the overall configuration of a payment system including the detection device of the present invention will be described.

  As shown in FIG. 1, the settlement system includes a settlement apparatus 1, a magnetic card 2, a mobile phone 3, a sales management apparatus 4, and an opening detection apparatus 5 (“detection apparatus”).

  The settlement apparatus 1 is, for example, a stationary information processing apparatus, and is attached with the opening detection apparatus 5 of the present invention.

  Further, the settlement apparatus 1 includes a card reader and can read personal information (for example, credit card company name, credit card member number, expiration date, credit line, etc.) stored in the magnetic card 2. It is. When the magnetic card 2 is composed of a non-contact type IC card, the settlement apparatus 1 communicates with the magnetic card 2 when reading the personal information from the magnetic card 2, and the personal information with the magnetic card 2. Receive.

  In this example, the settlement apparatus 1 is installed in a store where the credit function of the magnetic card 2 can be used.

  The magnetic card 2 is composed of a general magnetic card, and has a credit (credit sales) function that enables purchase of goods and the like by postpayment. That is, the magnetic card 2 and the settlement apparatus 1 perform a sales process that is a transaction by a credit function by cooperating with each other.

  The magnetic card 2 can store arbitrary information in a magnetic stripe formed on the surface thereof. For example, the magnetic card 2 stores a credit card company name, a credit card member number, an expiration date, a credit line (use limit amount), and the like.

  Sales data DT is transmitted from the settlement apparatus 1 to the sales management apparatus 4 via a network (not shown) every time a user purchases a product using the magnetic card 2. Here, the sales data DT includes, for example, the name of the store where the user purchased the product, the product purchased by the user (for example, a shirt, a bag), and the payment amount paid by the user in the transaction.

  The magnetic card 2 only needs to play a role of storing information that can be read by the settlement apparatus 1. For example, the magnetic card 2 may be composed of a contact type IC card, a non-contact type IC card, or the like.

  The mobile phone 3 has the same function as a general mobile phone such as a call function. In this example, the owner of the mobile phone 3 is the same as the owner of the magnetic card 2.

  The sales management device 4 is composed of a predetermined information processing device, and is installed in, for example, a credit card company that is the issuer of the magnetic card 2.

  The sales management device 4 receives the sales data DT transmitted from the settlement apparatus 1 via a network (not shown), and performs processing (so-called gathering) for managing the sales data DT.

  The opening detection device 5 is a “detection device” and is attached to the settlement apparatus 1. The opening detection device 5 detects that a lid 101 described later is opened in the payment device 1.

  Next, the internal configuration of the opening detection device 5 will be described in detail.

  As illustrated in FIG. 2, the opening detection device 5 includes acceleration sensors 51-1 to 51-2, a comparison unit 52, an opening detection unit 53, a storage unit 54, and a communication unit 55.

  The acceleration sensor 51-1 or 51-2 detects the first acceleration A1 or A2 at the position where the acceleration sensor 51-1 or 51-2 is attached. Then, the acceleration sensor 51-1 or 51-2 outputs acceleration detection signals S1 and S2 indicating the detected first acceleration A1 and second acceleration A2, respectively.

  Here, a connection (attachment) mode between the settlement apparatus 1 and the opening detection apparatus 5 will be described.

  As shown in FIG. 3 (a), the settlement apparatus 1 accommodates parts constituting the settlement apparatus 1, and includes a housing 102 having an opening, and a lid 101 for covering the opening of the housing 102. It is comprised from these two members.

  In this illustrative example, the lid 101 is rotatably attached to an opening located on the upper surface of the container 102 by a hinge (not shown). As shown in FIG. 3B, when the lid 101 is opened, the opening of the container 102 is opened. The lid 101 may have a structure that can be detached from the container 102.

  In this example, an acceleration sensor 51-1 that is a “first acceleration sensor” is attached to the inner surface of the lid 101.

  Further, an acceleration sensor 51-2 which is a “second acceleration sensor” is attached to the inner surface of the bottom surface of the container 102.

  In this illustrative example, the acceleration sensor 51-1 (first acceleration sensor) detects the first acceleration A1 applied to the lid 101 in the extending direction of the Z axis, which is a “predetermined axis”.

  Furthermore, the acceleration sensor 51-1 outputs an acceleration detection signal S1 indicating the magnitude of the detected first acceleration A1 and the action direction DR1.

  Here, the action direction DR1 is a direction (a positive direction or a negative direction on the Z axis) in which the first acceleration A1 acts on the lid 101 on the Z axis.

  Further, the acceleration sensor 51-2 (second acceleration sensor) detects the second acceleration A2 applied to the container 102 in the Z-axis extending direction.

  Furthermore, the acceleration sensor 51-2 outputs an acceleration detection signal S2 indicating the magnitude of the detected second acceleration A2 and the action direction DR2.

  Here, the action direction DR2 is a direction (a positive direction or a negative direction on the Z axis) in which the second acceleration A2 acts on the container 102 on the Z axis.

  The acceleration sensors 51-1 to 51-2 may be, for example, general MEMS (micro eletro mechanical systems) sensors created by a semiconductor process. Further, the acceleration sensor 51-1 or 51-2 is configured to detect the first acceleration A1 or the second acceleration A2 applied to the weight, for example, by detecting the amount of displacement of the weight attached to the spring. It may be.

  2 includes a first acceleration A1 indicated by the acceleration detection signal S1 output from the acceleration sensor 51-1, and a second acceleration A2 indicated by the acceleration detection signal S2 output from the acceleration sensor 51-2. Are compared at every predetermined timing.

  When the first acceleration A1 and the second acceleration A2 are different as a result of the comparison by the comparison unit 52, the opening detection unit 53 outputs an opening detection signal OP indicating that the lid 101 of the settlement apparatus 1 has been opened.

  The case where the opening detection signal OP is output is a case where there is a high possibility that the settlement apparatus 1 is vibrated due to fraud such as skimming.

  As shown in FIG. 4, when the lid 101 is opened, the first acceleration A1 of the lid 101 detected by the acceleration sensor 51-1 is an acceleration determined by the magnitude of the force F acting on the end of the lid 101. Become. On the other hand, the second acceleration A2 of the container 102 detected by the acceleration sensor 51-2 is “0”. That is, in the example shown in FIG. 4, since the first acceleration A1 and the second acceleration A2 are different, the opening detection unit 53 detects that the lid 101 is opened.

  In addition, as shown in FIG. 5, when the force F for opening the hole (broken-line part shown in FIG. 5) which penetrates the said lid | cover 101 is acting in the state with the lid | cover 101 closed, the acceleration sensor 51 is applied. -1 detects the acceleration according to the magnitude of the force F acting on the lid 101 as the first acceleration A1. On the other hand, the second acceleration A2 of the container 102 detected by the acceleration sensor 51-2 is substantially “0”.

  When an illegal opening / closing action of the lid 101 is detected by a mechanical switch, an illegal action on the lid 101 cannot be detected if a hole is pierced and penetrated at a position on the settlement apparatus 1 where the mechanical switch does not operate. However, the opening detection device 5 of the present invention can detect fraudulent acts on the lid 101 of the settlement device 1.

  In each of FIGS. 4 and 5 described above, the positive direction on the Y-axis is the direction from the front to the back of the page.

  The storage unit 54 stores arbitrary information. For example, the storage unit 54 stores alarm destination information 541.

  The alarm destination information 541 is information in which a destination to which the communication unit 55 transmits an abnormality alarm NF is stored. Here, the abnormality alarm NF is an alarm indicating that the lid 101 has been opened. When the abnormality warning NF is transmitted, there is a possibility that fraudulent acts on the settlement apparatus 1 are being performed. In this explanation example, the mobile phone 3 is stored in the alarm destination information 541 as the transmission destination of the abnormality alarm NF.

  The communication unit 55 includes, for example, a communication module, and transmits / receives arbitrary information to / from the mobile phone 3 by connecting the open detection device 5 and the mobile phone 3 to be communicable.

  For example, when the opening detection unit 53 outputs the opening detection signal OP, the communication unit 55 (“transmission unit”) stores an abnormality alarm NF indicating that the lid 101 is opened in the settlement apparatus 1 in the alarm destination information 541. It is transmitted to the alarm destination (in this example, the mobile phone 3). Note that the communication unit 55 (transmission unit) may transmit the abnormality alarm NF to the sales management device 4.

  Next, an operation in which the opening detection device 5 having the above configuration detects that the lid 101 has been opened in the settlement apparatus 1 will be described.

  As shown in FIG. 6, the acceleration sensor 51-1 detects the first acceleration A1 applied to the lid 101 and the direction of action DR1 of the first acceleration A1. Then, an acceleration detection signal S1 indicating the detected first acceleration A1 and acting direction DR1 is output (step 601).

  The acceleration sensor 51-2 detects the second acceleration A2 applied to the container 102 and the direction of action DR2 of the second acceleration A2. Then, an acceleration detection signal S2 indicating the detected second acceleration A2 and acting direction DR2 is output (step 602).

  Subsequently, the comparison unit 52 compares the first acceleration A1 and the second acceleration A2 (step 603).

  As a result of the comparison by the comparison unit 52, when the first acceleration A1 and the second acceleration A2 are different, the opening detection unit 53 outputs an opening detection signal OP indicating that the lid 101 has been opened (step 604).

  When the opening detection unit 53 outputs the opening detection signal OP, the communication unit 55 (transmission unit) displays an abnormality alarm NF indicating that the lid 101 has been opened in the settlement apparatus 1 as an alarm destination indicated by the alarm destination information 541 (this In the example, it is transmitted to the mobile phone 3) (step 605).

  Thus, a series of operations in which the opening detection device 5 detects that the lid 101 has been opened in the settlement device 1 is completed.

  As described above, according to the opening detection device 5 of the present invention, the first acceleration A1 or the accommodation of the lid 101 using the acceleration sensor 51-1 or 51-2 attached to the lid 101 or the accommodation body 102, respectively. Each of the second accelerations A2 of the body 102 is detected. The comparison unit 52 compares the first acceleration A1 and the second acceleration A2. When the first acceleration A1 and the second acceleration A2 are different from each other as a result of the comparison, the opening detection unit 53 outputs an opening detection signal OP indicating that the lid 101 is opened.

  Thereby, even when the settlement apparatus 1 is configured by a plurality of members (the lid 101 and the container 102) whose positions change relatively, it is possible to detect a change in the relative position and thus open the lid 101. It is possible to detect an operation for illegally crafting the inside of the payment apparatus 1.

  In the present invention, the processing in the opening detection device 5 is performed on a recording medium that can be read by the opening detection device 5 in addition to the above-described dedicated hardware. The recorded program may be read by the opening detection device 5 and executed. The recording medium readable by the opening detection device 5 indicates a transfer medium such as a floppy disk (registered trademark), a magneto-optical disk, a DVD, and a CD, and an HDD incorporated in the opening detection device 5. . The program recorded on the recording medium is read by, for example, the comparison unit 52 and the opening detection unit 53 included in the opening detection device 5, and the same processing as described above is performed under the control of the comparison unit 52 and the opening detection unit 53. Is done.

  Here, the comparison unit 52 and the opening detection unit 53 included in the opening detection device 5 operate as a computer that executes a program read from a recording medium.

  The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments.
