Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a magnetic card reader in a security system for permitting the use of the device in a computer system with an ID card inserted.

[0002] In recent computer systems, in order to improve security in business processing, ID cards (IDs are recorded according to ranks of business content are recorded in order to allow only a person according to the business content to operate the device. Magnetic card) is read into the device.

Particularly in a financial system or the like, after an ID card for operating the device is read, business processing is performed with the card still inserted in the device, and approval of the business processing result is required. In such cases, the ID card for approval is read and the approval process is performed. For example, the card is used in combination to ensure security.

However, if the removal of the inserted card cannot be detected with certainty, it may be diverted to another device, resulting in a decrease in security. Therefore, there is a demand for a small and simple manual magnetic card reader that prevents unauthorized use.

[0005]

2. Description of the Related Art FIG. 8 is an explanatory view of a conventional example. When the operator performs business processing using the terminal device 19, a magnetic card (ID card) is manually moved along the travel guide 11 and then inserted into the card holder 12.

The running guide 11 is provided with a magnetic head 13 for reading the magnetic stripe MS16 of the magnetic card 15, and the card holder 12 has a sensor 14 for detecting the inserted magnetic card 15, for example, a light transmission type. A sensor is provided, and an ID (identification number) recorded on the magnetic stripe 16 is read and transmitted to the terminal device 19 by the operator's operation of the magnetic card, and the magnetic card 15 is also provided.
A signal indicating whether the card has been inserted into or removed from the card holder 12 or a card detection state signal is transmitted to the terminal device 19.

In the terminal device 19, the received ID is sent to the host 17
If you are registered, send it to
When the magnetic card 15 is set in the card holder 12 (hold status information 18 is turned on by the sensor detection notification), business processing is permitted, and card removal from the card holder 12 is detected (hold status information). (If 18 is on and the sensor is not detected), stop the business process.

In the case of a financial terminal, when the transaction amount is equal to or more than a predetermined amount, it is general that an approval process is required.
After the ID card of the operator is inserted in the card holder 12, the officer reads his or her ID card into the magnetic card reader and then performs the approval process to prevent the transaction process from being fraudulent.

[0009]

In the system using the manual type magnetic card reader described above, business processing is permitted while the read ID card is inserted in the card holder 12. , Even if another card is inserted into the card holder 12 after the ID card is read, the sensor 14 detects that the card has been inserted, so that the ID card can be used in another device, which causes a security problem. To do.

In order to solve this, a method of incorporating a magnetic card reader into the terminal device 19 and operating the ID card while it is read in the device is adopted. However, the device becomes large or the terminal device is widely used. There are new problems such as the fact that they cannot be used, the size of the device becomes large and the installation property deteriorates.

In view of the above problems, it is an object of the present invention to provide a simple manual magnetic card reader with improved security.

[0012]

In order to achieve the above object, a magnetic card reader according to the present invention, as shown in the principle diagram of the present invention in FIG. 1, includes (1) a running guide 1 for running a magnetic card; The stopper 2 for stopping the traveling of the magnetic card 5 in the traveling guide 1 at a predetermined position and the recorded contents of the magnetic body portion 6 included in the magnetic card 5 from the traveling magnetic card 5 are read and stopped at the predetermined position. The magnetic head 3 for detecting the predetermined magnetic material portion 7 of the magnetic card 5 and whether or not the magnetic card 5 read by detecting or not detecting the predetermined magnetic material portion 7 is held in the traveling guide. And a magnetic card hold detection unit 4 that operates. (2) In the configuration of (1) above, a card removal detection unit that determines the removal of the card when detecting the transition of the magnetic card 5 from the holding state to the non-holding state is provided. (3) In the configuration of (2) above, a timer is provided for counting the card removal detection as a trigger for a predetermined time, and the card removal detection unit holds the card removal detection notification during the predetermined time and removes the card within the predetermined time. When the same magnetic card as the card is read, it is determined that the holding state of the magnetic card has continued. (4) In the above (3), when the read data in the backward direction of the held magnetic card matches the read data in the forward direction, it is determined that the holding state of the magnetic card is continued. (5) In (3) or (4) above, when the second magnetic card different from the first one read during the predetermined time is read, it is determined that the holding state of the magnetic card is continued. Is configured to validate the data read from the second magnetic card.

[0013]

[Action]

(1) The operator manually runs the magnetic card 5 in the running guide 1 and leaves the magnetic card 5 at the position stopped by the stopper 2. During this time, the magnetic head 3 reads the recorded contents of the magnetic body portion 6 of the magnetic card 5, and at the same time, the magnetic portion 6 of the magnetic body portion 6 of the magnetic card 5 stopped at a predetermined position does not record data. To detect.

The magnetic card hold detector 4 determines whether or not the magnetic card 5 read by detecting or not detecting the predetermined magnetic body portion 7 is held as it is in the traveling guide.

As described above, by allowing the magnetic card 5 to run up to the stopper 2 and leaving it as it is, predetermined business processing is permitted. As a result, when business processing is permitted by inserting one ID card, card replacement at the time of re-insertion can be prevented as compared with the method of re-inserting the card shown in the conventional example, improving security. To be done. (2) In the above (1), a card removal detection unit is provided, and when it is detected that the magnetic card is in the held state and not held, it is determined that the card is removed. As a result, the business process being processed is prohibited. (3) In the configuration of (2) above, a timer is provided that counts for a predetermined time by using the card removal detection as a trigger. The card removal detection unit holds the card removal detection notification during counting for the predetermined time, and if the same magnetic card as the removed magnetic card is read within the predetermined time, the magnetic card is stored in the magnetic card reader. It is determined that it was held in.

In other words, if the same card is re-inserted within a short time such that unauthorized use is impossible, it is assumed that the card has not been removed. As a result, the running guide becomes empty and other cards can be read, and important tasks can be processed by using two cards together while maintaining security.

Comparing this point with the conventional example, the conventional example cannot identify the difference between the cards even if another card is inserted into the card holder.
Since D is read and compared, it is possible to prevent re-insertion of a false card and improve security. (4) In the above (3), when the magnetic card held for reading the second card is removed, the magnetic card is run in the reverse direction to read the recorded contents. When the read data in the backward direction matches the read data in the first forward direction, it is determined that the holding state of the card is continuing.

As described above, since the removed card can be identified as the same card as the card inserted first, the replacement of the card in the holding state can be detected, and the security is further improved. (5) In (3) or (4) above, when the second magnetic card different from the magnetic card is read during the predetermined time, if it is determined that the holding state of the magnetic card is continued, The data read from the second magnetic card is valid.

As described above, by holding the read magnetic card as it is with the stopper 2, it is possible to prevent replacement with an unauthorized card. Further, when the same card is read within a relatively short period of time, it can be used together with other cards by putting the card in the holding state. Also in this case, the security is further improved by defining the extraction method as described in (4) above.

FIG. 2 is a block diagram of an embodiment, FIG. 3 is a diagram showing an operation example, FIG. 4 is an explanatory diagram of a security function by two cards, FIG. 5 is an explanatory diagram of a security function by reverse reading and sampling, and FIG. Is a security function explanatory diagram with one card, and FIG. 7 is a diagram showing another stopper mechanism example.

In this embodiment, an example applied to a security mechanism using two ID cards in combination, which is implemented in a financial system or the like, will be described. In the magnetic card reading unit 20 of FIG. 2, 22 is a stopper, which is composed of a guide or the like for stopping the magnetic card 30. The position is a magnetic card stopped
The data recording section 32 in the magnetic stripe of 30 is the magnetic head 23.
Is determined to be located in the non-recording portion 33 where data is not actually recorded although it is beyond the position of and is a magnetic material portion in the magnetic stripe. The structure of the traveling guide 21 is
When the magnetic card 30 is run and the stopped magnetic card 30 is verified by reverse reading, it can be run in the right direction in the drawing and pulled out. Normally, the structure is such that it can be pulled out upward.

A magnetic head 23 reads the contents of the data recording section 32 of the magnetic material portion (magnetic stripe portion; MS portion 31) of the magnetic card 30 which travels in the left-right direction in the drawing in the traveling guide and also serves as a stopper. The presence or absence of magnetism in the non-recording portion 33 of the magnetic card 30 stopped at the position 22 is detected.

Reference numeral 27 is a reading control section, which converts the signal output from the magnetic head 23 into a code and transmits it to the terminal device 19 through the interface section 29. 24 is a sampling detection part, MS part
A magnetic detection unit 25 that detects the magnetic signal of 31 and binarizes it, a memory 34 that stores the data read by the reading control unit 27, and a data comparison unit 26 that performs sampling detection control by data comparison.

Reference numeral 28 denotes a timer, which counts a predetermined time, and when the time-out occurs, notifies the terminal device 19 of the removal detection through the interface unit 29. With the above configuration, the operator operates the magnetic card 30 as follows. (1) Insert the first card A (magnetic card 30), run it until it stops at the stopper 22, and hold the card A at that position. (2) If the ID read from the running card A and the registered ID match, the terminal device can be operated. (3) The operator performs a predetermined transaction operation. (4) If approval is required, first remove Card A. (5) Then, the card B is run. (6) After removing the card A, run the card A again within a predetermined time and hold it at the stopper position. (7) Perform approval processing.

By the above operation, the following operation is performed in the magnetic card reader. (A) In the case of the method of extracting the first card A in an arbitrary direction (see FIG. 4) The data D1 (ID; identification number) read by the running of the magnetic card 30 (card A) at time t0 is the terminal It is sent to the device 19 and the data comparison unit 26. Magnetic detector 25
Detects and notifies the data D1, or when the non-recording unit 33 of the stopped magnetic card 30 detects and notifies the magnetism, the data comparison unit 26 stores the data D1 in the memory 34 and the terminal device
Notify 19 of card insertion. As a result, the terminal device 19 sets the hold state information 18 to the hold state, transmits the data D1 to the host 17 and inquires about the presence or absence of ID registration, and permits the transaction processing if registered.

When the card A is removed in this state (time t1), the magnetism detecting section 25 cannot detect the magnetism of the non-recording section 33, so it is determined that the card is removed and the data comparing section 26 is notified. As a result, the data comparison unit 26 activates the timer 28. Thereafter, the data comparison unit 26 compares the next read data (time t2) with the data D2 stored in the memory 34,
When they match, the timer unit 28 is reset and the counting is stopped. [(1) in FIG. 4] When the matched data is not read within the predetermined time T, a time-out occurs, the terminal device 19 is notified of the card removal, and the terminal device 19 resets the hold state information 18. Prohibit operation. [Fig. 4
(2)] When the card B is read within a predetermined time T after the timer 28 starts counting and the card A is read within the predetermined time T, the read data of the card B is valid. As a result, the approval process is permitted. (B) In the case of removing in the reverse direction (see FIG. 5) In the above (A), the case of removing the card A in any direction is shown. That is, it is pulled out in the right direction in FIG.

Therefore, the data comparison unit 26 stores the data D3 (rearranged in the opposite direction) read in the hold state and the memory.
If the data D1 of 34 is compared and they match (time t1)
Notifies the terminal device 19 of normal removal and starts the timer 28. The terminal device 19 refers to the second card data D3 to the host 17 if there is no card removal notification even after a lapse of a predetermined time, and permits the approval process if registered. Note that the hold state continuation process by re-reading is the same as the above-described (A).

As described above, it is possible to perform business processing by using two cards together (and reading). Note that FIG. 6 shows the case where the above-mentioned approval process is not performed, or
The case where processing is performed by one magnetic card 30 is shown.

When the card is made to travel in this figure, the reading is started from time t0, so that the removal detecting unit recognizes that the holding is started. The process is performed until time t1 and the magnetism is not detected when the process is taken out. Therefore, the process is prohibited after the time-out as the detection of removal.

It should be noted that processing is performed with only one card,
When not used together, the sampling detection by the timer 28 and data comparison is unnecessary. FIG. 7 shows another example of the stopper when two cards are used together. When the card A is run, the stopper 22a is closed as shown to stop the magnetic card 30 and the card B is run. When this is done, the stopper 22a is opened so that the card B can pass through the running guide 1. This improves the operability.

Of course, the hold status information 18 may be provided in the magnetic card reader to notify the terminal device 19 of the change. As described above, since the magnetic card 30 that has been run by the stopper mechanism is held as it is, it is difficult to replace the card and it is possible to prevent unauthorized use. Even when two cards are used together, it is possible to read the same card again for a short time to remove the card so that another card can be read and the reverse reading can be performed during the removal. Therefore, the security is greatly improved as compared with the conventional example.

[0032]

As described above, in the magnetic card reader of the present invention, the magnetic card read by manual scanning by the stopper mechanism is stopped and held at the stop position. This has the effect of preventing unauthorized use of devices and business processes.

Also, when two cards are used together, the same card is re-read so that a short-time removal can be recognized as a hold state and another card can be read, and further reverse reading can be performed to read data in the forward direction. When it coincides with the above, the second card within a short period of time is read as normal removal, so that there is a significant improvement in security compared to the conventional method of holding the card in the card holder.
