Description

  The present invention relates to a card processing device and a data reading device for reading magnetic data recorded on a magnetic card.

  Conventionally, an insertion slot into which a magnetic card is inserted, a card insertion detection unit for detecting that a magnetic card has been inserted into the insertion slot, and a shutter member for opening and closing the insertion slot based on the detection result of the card insertion detection unit And a card processing device including a read / write head that performs processing on a magnetic card inserted from an insertion slot is known (see, for example, Patent Documents 1 to 3).

  These card processing devices are configured to prevent unauthorized acquisition of magnetic information by the unauthorized acquisition device when the unauthorized acquisition device of magnetic information is attached in front of the insertion slot. The fraudulent acquisition device is provided with a magnetic head for reading magnetic data.

  Specifically, in the card processing apparatus of Patent Document 1, a photosensor for detecting foreign matter is provided in the vicinity of the insertion slot. The card processing device prevents the magnetic information from being illegally acquired by stopping the taking-in of the magnetic card and issuing an alarm when the unauthorized acquisition device is detected by the photosensor.

  In the card processing device of Patent Document 2, a magnetic field generator that generates a disturbing magnetic field is provided in front of the insertion slot. The card processing device prevents unauthorized acquisition of magnetic information by making it difficult for the unauthorized acquisition device to read magnetic data with a magnetic field generator.

  Since the card processing device of Patent Document 3 described above requires that the magnetic head be continuously moved with respect to the magnetic stripe of the magnetic card in order to read the magnetic data of the magnetic card, the magnetic card is intermittently conveyed. This makes it difficult to read magnetic data by an unauthorized acquisition device, thereby preventing unauthorized acquisition of magnetic information.

  Hereinafter, first to third embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
First, with reference to FIGS. 1-6, the structure of the card processing apparatus 100 and ATM (Automated Teller Machine) 150 by 1st Embodiment of this invention is demonstrated.

  As shown in FIG. 1, the ATM 150 includes an ATM main body 151, a power source 152, and a card processing device 100. The ATM 150 is installed in a financial institution or the like so that a user can perform transactions such as cash withdrawal.

  The card processing apparatus 100 according to the first embodiment is provided in the ATM 150 and is supplied with power from a power source 152. The card processing apparatus 100 is configured to perform a predetermined process on the magnetic stripe 161 of the magnetic card 160 inserted by the user.

  Specifically, the card processing apparatus 100 reads the magnetic data recorded on the magnetic stripe 161 of the magnetic card 160 and transmits the read data to the ATM main body 151. The card processing apparatus 100 receives data transmitted from the ATM main body 151 and writes the received data to the magnetic stripe 161 of the magnetic card 160.

  The magnetic stripe 161 is provided with three tracks, and magnetic data is recorded on each track using, for example, F2F (Two Frequency Coherent Phase Encoding).

  As shown in FIG. 2, the card processing apparatus 100 includes a housing 1, conveyance rollers 2 a to 2 d, card position detection units 3 a to 3 c, a read / write head 4, a shutter member 5, and a shutter position detection. Part 6 and card insertion detection part 7 are included. The card insertion detection unit 7 is an example of the “data reading device” in the present invention.

  The housing 1 is provided with an insertion slot 1a into which the magnetic card 160 is inserted at the end on the arrow X2 direction side. Each of the transport rollers 2a to 2d is provided in a pair of upper and lower sides across the transport path P, and transports the magnetic card 160 in the insertion direction (arrow X1 direction) and the discharge direction (arrow X2 direction).

  The card position detection units 3a to 3c are, for example, photo interrupters, and detect the position of the magnetic card 160 on the transport path P. The read / write head 4 reads and writes data with respect to the inserted magnetic card 160.

  The shutter member 5 is provided to be movable in the opening direction (arrow Z1 direction) and the closing direction (arrow Z2 direction) in order to open and close the insertion slot 1a. The shutter position detector 6 is a micro switch, for example, and detects that the shutter member 5 has moved to the closed position.

The card insertion detector 7 is provided inside the magnetic head 70 as shown in FIG. The magnetic head 70 is provided so as to be movable in the arrow Z1 direction and the arrow Z2 direction (see FIG. 2). Specifically, the magnetic head 70 is in front of the shutter member 5 in the insertion slot 1a and protrudes into the insertion slot 1a. When the magnetic card 160 is inserted into the insertion slot 1a, the magnetic head 160 In the state of contact with the magnetic stripe 161 (see FIG. 1), it retracts in the direction of the arrow Z1. The magnetic head 70 is provided with a card insertion detector 7 for each track of the magnetic stripe 161 (see FIG. 1).

  Further, as shown in FIG. 4, the magnetic head 70 has a direction in which the track 161a of the magnetic stripe 161 extends when the magnetic card 160 is inserted into the insertion slot 1a, that is, a magnetic data recording direction (the direction of the arrow X1 and the arrow). (X2 direction).

As illustrated in FIG. 3, the card insertion detection unit 7 includes a reading unit 71, a decoding unit 72, a conversion circuit 73, and an output unit 74. These are integrated in the magnetic head 70. The conversion circuit 73 is an example of the “conversion unit” in the present invention. The reading unit 71 includes a core 71b having a gap 71a and a coil 71c, and reads magnetic data recorded on the magnetic card 160.

  In the reading unit 71, when the magnetic card 160 is inserted into the insertion slot 1a, the core 71b is magnetized by the magnetization pattern of the magnetic card 160, whereby a current flows through the coil 71c. Thereby, the reading unit 71 outputs a reproduction signal as shown in FIG. 5 to the decoding unit 72, for example. FIG. 5 shows a part of the reproduction signal for simplification. The actual reproduction signal differs depending on the magnetic data recorded on the magnetic stripe 161 of the magnetic card 160.

  The decoding unit 72 decodes the reproduction signal into binary data (“1010111010” in the example of FIG. 5) by determining the presence / absence of a detection pulse for each predetermined period. The conversion circuit 73 performs irreversible conversion on the magnetic data read from the magnetic card 160 by extracting predetermined data from the data decoded by the decoding unit 72. For example, when the data decoded by the decoding unit 72 is “1010111010”, the data is extracted (sampled) every 3 bits and converted to “100”. It is impossible to restore the original data “10101110” from the converted data “100”. The output unit 74 outputs the data irreversibly converted by the conversion circuit 73 to the control unit 11 described later. That is, the output unit 74 outputs data that cannot be restored to the magnetic information recorded on the magnetic card 160 to the control unit 11.

  Further, as shown in FIG. 6, the card processing apparatus 100 exchanges data with the ATM main body 151 and the motor 9 that drives the transport rollers 2 a to 2 d, the actuator 9 that includes a solenoid for moving the shutter member 5, and the like. The communication part 10 for performing this, and the control part 11 which controls operation | movement of the card processing apparatus 100 are included.

  The control unit 11 includes a CPU, a ROM, a RAM, and the like. The control unit 11 determines that the magnetic card 160 has been inserted into the insertion slot 1 a of the housing 1 when data subjected to irreversible conversion is input from the card insertion detection unit 7. Note that the control unit 11 cannot know the magnetic information (the contents of the magnetic data) recorded on the magnetic card 160 based on the irreversibly converted data input from the card insertion detection unit 7, but the magnetic card It is only necessary to determine whether or not 160 has been inserted.

  Next, the operation of the card processing apparatus 100 according to the first embodiment of the present invention will be described with reference to FIGS. 2, 3 and 6 to 10. Each step in the flowchart of FIG. 7 is executed by the control unit 11 (see FIG. 6).

  First, in the card processing apparatus 100, the magnetic card 160 (see FIG. 2) is inserted into the slot 1a (see FIG. 2) of the housing 1 based on the detection result of the card insertion detection unit 7 (see FIG. 2) in step S1 of FIG. 2) is determined. Specifically, it is determined whether or not the data irreversibly converted by the conversion circuit 73 (see FIG. 3) is output from the output unit 74 (see FIG. 3). If it is determined that the losslessly converted data is not output from the output unit 74 and the magnetic card 160 is not inserted into the insertion slot 1a, step S1 is repeated. That is, the card processing apparatus 100 stands by until the magnetic card 160 is inserted. Then, when the data subjected to the irreversible conversion is output from the output unit 74 and it is determined that the magnetic card 160 is inserted into the insertion slot 1a, the process proceeds to step S2.

  Next, in step S2, the shutter 9 (see FIG. 2) is moved in the opening direction (arrow Z1 direction) by the actuator 9 (see FIG. 6). As a result, as shown in FIG. 8, the shutter member 5 is retracted from the transport path P, so that the insertion port 1a is opened. Next, in Step S3, the conveyance rollers 2a to 2d (see FIG. 8) are rotated forward by driving the motor 8 (see FIG. 6). As a result, the magnetic card 160 is conveyed in the direction of the arrow X1, so that the magnetic card 160 is taken into the housing 1 as shown in FIG. The insertion slot 1a is closed by the shutter member 5 after a predetermined time has elapsed since it was opened.

  Next, in step S4, the reading / writing head 4 reads and writes data to and from the magnetic card 160 while the magnetic card 160 taken into the housing 1 is transported to the position indicated by the broken line. Is done. At this time, communication with the ATM main body 151 (see FIG. 6) is also performed via the communication unit 10 (see FIG. 6).

  Thereafter, when a discharge command for the magnetic card 160 is input from the ATM main body 151, the shutter member 5 is moved in the arrow Z1 direction by the actuator 9 in step S5. As a result, as shown in FIG. 10, the shutter member 5 is retracted from the transport path P, so that the insertion port 1a is opened. Next, in step S6, the conveyance rollers 2a to 2d are reversed by driving the motor 8. As a result, the magnetic card 160 is conveyed in the direction of the arrow X2 and is ejected from the insertion slot 1a.

  Next, in step S7, based on the detection result of the card insertion detection unit 7, it is determined whether or not the magnetic card 160 has been removed from the insertion slot 1a. If it is determined that the magnetic card 160 has not been removed, step S7 is repeated. That is, the card processing apparatus 100 stands by until the magnetic card 160 is removed. When it is determined that the magnetic card 160 has been removed, the insertion slot 1a is closed by the shutter member 5, and the series of operations is completed.

  In the first embodiment, as described above, the conversion circuit 73 that performs irreversible conversion on the magnetic data read by the reading unit 71 and the output unit 74 that outputs the data irreversibly converted by the conversion circuit 73 are provided. Thus, even if the data converted through the lead wire is illegally acquired from the output unit 74 by connecting the lead wire directly to the output line of the magnetic head 70, the magnetic information is converted from the converted data. Since (content of magnetic data) cannot be restored, it is possible to prevent illegal acquisition of magnetic information. As a result, the card processing apparatus 100 according to the first embodiment can detect the insertion of the magnetic card 160 and open the insertion slot 1a while preventing the magnetic information from being illegally acquired.

  In the first embodiment, the predetermined data is extracted from the decrypted data, and the magnetic data read from the magnetic card 160 is irreversibly converted, so that the restoration from the magnetic data read by the reading unit 71 is not possible. Possible data can be created easily.

  Also, in the first embodiment, unlike the case where the magnetic data is encrypted by irreversibly converting the magnetic data read from the magnetic card 160, the encrypted magnetic data and key data are stolen. Thus, there is no possibility that the encrypted magnetic data is decrypted and the magnetic information is illegally acquired.

(Second Embodiment)
Next, the configuration of the card processing device 200 according to the second embodiment of the present invention will be described with reference to FIGS. 2 and 11 to 14.

  As shown in FIG. 11, the card processing device 200 according to the second embodiment includes a card insertion detection unit 201 and a control unit 202. The card insertion detection unit 201 is an example of the “data reading device” in the present invention. The structure of the card processing apparatus 200 is the same as that in FIG.

  As shown in FIG. 12, the card insertion detection unit 201 includes a reading unit 203 that reads magnetic data recorded on the magnetic card 160 and an output unit 204 that outputs a reproduction signal of the reading unit 203. The reading unit 203 includes a core 203b in which a gap 203a is formed, and a coil 203c.

  The card insertion detection unit 201 is provided inside the magnetic head 205. The magnetic head 205 is provided with a card insertion detector 201 for each track of the magnetic stripe 161 (see FIG. 1).

  As shown in FIG. 13, the magnetic head 205 has a direction in which the track 161a of the magnetic stripe 161 extends when the magnetic card 160 is inserted into the insertion slot 1a (see FIG. 2), that is, a magnetic data recording direction (arrow X1). Direction and the direction of the arrow X2). That is, the reading unit 203 of the card insertion detection unit 201 is disposed so as to be inclined with respect to the magnetic data recording direction.

  Therefore, the gap 203a of the reading unit 203 is arranged so as to be inclined with respect to the magnetic data recording direction, and the reading unit 203 reads the magnetic data recorded on the magnetic card 160 simultaneously for a plurality of bits. In this case, the intensity of the magnetic field (magnetic field in the A direction component) appearing in the gap 203a due to the magnetic stripe 161 is reduced, and the data of adjacent bits are mixed. For example, the magnetic data recorded on the magnetic card 160 is In the case of “1010111010”, the reading unit 203 outputs a reproduction signal as shown in FIG. This reproduced signal is significantly different from the original reproduced signal shown in FIG. 5, and it is impossible to restore the original data from the signal shown in FIG. That is, the reading unit 203 reads a signal that cannot be restored to the magnetic information recorded on the magnetic card 160.

  The output unit 204 outputs a reproduction signal that cannot be restored to the magnetic information recorded on the magnetic card 160 to the control unit 202. The control unit 202 determines that the magnetic card 160 has been inserted into the insertion slot 1 a of the housing 1 when a reproduction signal is input from the card insertion detection unit 201. The control unit 202 cannot know the magnetic information (content of magnetic data) recorded on the magnetic card 160 based on the reproduction signal input from the card insertion detection unit 201, but the magnetic card 160 is inserted. It suffices if it is possible to determine whether or not.

  Other configurations of the card processing device 200 are the same as those of the card processing device 100 described above.

  In the second embodiment, as described above, the lead wire is directly connected to the output line of the magnetic head 205 by providing the magnetic head 205 and the reading unit 203 so as to be inclined with respect to the recording direction of the magnetic data. Thus, even when a reproduction signal is illegally acquired from the output unit 204 via the lead wire, the magnetic information (content of magnetic data) cannot be restored from the reproduction signal, so that the magnetic information is illegally acquired. Can be prevented. As a result, the card processing device 200 according to the second embodiment can detect the insertion of the magnetic card 160 and open the insertion slot 1a while preventing the magnetic information from being illegally acquired.

  In the second embodiment, by reading a signal that cannot be restored to the magnetic information recorded on the magnetic card 160, a signal that cannot be restored can be easily output. .

The conversion circuit 313 is an example of the “conversion unit” in the present invention.

  The conversion circuit 313 performs irreversible conversion on the data decrypted by the decryption unit 312 using a hash function. Here, the hash function is a function that outputs fixed-length data from an input and is an irreversible one-way function. For this reason, it is impossible to restore the original data from the converted data. The output unit 314 outputs the data irreversibly converted by the conversion circuit 313 to the comparison unit 303.

  The storage unit 302 is, for example, a flash memory, and stores data obtained by irreversibly converting magnetic data of the magnetic card 360 using a hash function. The comparison unit 303 includes a CPU, a ROM, a RAM, and the like, and compares the data output from the output unit 314 with the data stored in the storage unit 302. Then, the comparison unit 303 outputs the comparison result to the gate control unit 352 via the communication unit 304.

  The gate control unit 352 controls the open / close state of the key of the gate 351 based on the comparison result input from the communication unit 304. Specifically, the gate control unit 352 opens / closes the key of the gate 351 when a comparison result indicating that the data output from the output unit 314 matches the data stored in the storage unit 302 is input. Switch. On the other hand, when the comparison result that the data output from the output unit 314 does not match the data stored in the storage unit 302 is input, the gate control unit 352 changes the key open / close state of the gate 351. maintain.

  In the third embodiment, as described above, the conversion circuit 313 that performs irreversible conversion on the magnetic data read by the reading unit 311 and the output unit 314 that outputs the data irreversibly converted by the conversion circuit 313 are provided. Thus, even if the data converted through the lead wire is illegally acquired from the output unit 314 by connecting the lead wire directly to the output line of the magnetic head 310, the magnetic data is converted from the converted data. Since (content of magnetic data) cannot be restored, it is possible to prevent illegal acquisition of magnetic information. As a result, the card processing device 300 according to the third embodiment can authenticate the magnetic card 360 while preventing the magnetic information from being illegally acquired.

  In the third embodiment, data that cannot be restored from the magnetic data read by the reading unit 311 can be easily created by performing irreversible conversion on the decrypted data using a hash function.

Then, the output unit 314 outputs the comparison result from the comparison unit 316. If comprised in this way, the confidentiality of the magnetic data reading part 500 can be improved more.

  In the third embodiment, the example in which the configuration of the reading unit 311 is the same as that of the reading unit 71 of the first embodiment (FIG. 3) is shown. However, the configuration is not limited to this, and the configuration of the reading unit 311 is the second. It may be the same as the reading unit 203 of the embodiment (FIG. 12).
