Description

  The present invention relates to a data processing apparatus and a security system provided with a storage device such as a memory.

  A data processing device such as a POS (Point Of Sales) terminal that can make a payment with a credit card, a debit card or the like encrypts a communication message with a host computer of a financial institution designated by the payment card and transmits / receives it. To improve security. Therefore, key data required for encryption and restoration of ciphertext is recorded in advance in a memory built in the data processing apparatus. By using these key data, it becomes possible to access the host computer of the financial institution without going through the data processing device, so that it is easy to carry out fraud.

As described above, a data processing apparatus has been proposed in which measures are taken so that a memory storing important information such as key data cannot be illegally acquired (for example, Patent Document 1). This data processing device includes an anti-tamper means for making the memory inaccessible when detecting the cover open of the main body. For this reason, when the cover is opened, it becomes inaccessible regardless of the situation, but the inaccessible state is canceled by inputting a predetermined password, so it can be recovered quickly even after the cover is opened due to an erroneous operation. . Furthermore, an attempt is made to facilitate the discovery of fraud by notifying by issuing a warning that there is a cover open when the data processor is next started.

Processing information and the like are printed.

FIG. 3 is a block diagram showing a main configuration of the data processing apparatus 1 according to the present embodiment.
The data processing apparatus 1 is equipped with a CPU 20 as a control center. For this CPU 20, a chip set 21, ROM (Read Only Memory) 22, RAM (Random Access Memory) 23, BIOS-ROM (Basic Input / Output System-Read Only Memory) 24, display controller 25, card reader controller 26, Printer controller 27, camera controller 28, hard disk (HDD) 29, communication interface (I / F) 30, RTC (Real Time Clock) 31, temperature sensor 32, cover sensors S1, S2, S3, and latch circuits L1, L2 are addresses. They are connected via a bus line 40 such as a bus or a data bus.

  The chip set 21 includes a north bridge used to control information distribution such as management of data transfer and connect the CPU 20 and the bus line 40, and a south bridge having functions of various controllers. The ROM 22 stores in advance a program for executing the control operation of the CPU 20. The RAM 23 forms various memory areas that the CPU 20 uses for arithmetic processing.

  The BIOS-ROM 24 records a POST (Power-On Self Test), a BIOS driver, a VGA (Video Graphics Array) driver, and the like, which are test programs executed when initializing each hardware.

The display controller 25 displays a message or the like on the touch panel display 7 and performs a process of taking input data in accordance with a touch operation of the touch panel display 7 by the user. The card reader controller 26 controls driving of the card reader 8.
The hard disk 29 stores various databases necessary for settlement of transaction processing, encryption and restoration key data used in communication with a bank host computer, various programs, and the like. The printer controller 27 drives and controls the printer 41. The printer 41 is a so-called thermal printer including the platen cover 10, the platen roller 11, a thermal head, and the like as constituent elements.

  The camera controller 28 drives and controls the CCD camera 4 to photograph the periphery of the data processing apparatus 1. Video or still images taken by the CCD camera 4 are stored in the hard disk 29. The communication interface 30 controls communication between the data processing apparatus 1 and a bank host computer or the like, and transmits and receives the ciphertext and the like via a wired or wireless LAN (Local Area Network).

  The RTC 31 is a timekeeping chip incorporating a small battery. The RTC 31 operates with the operation voltage when the operation voltage is taken in the data processing device 1, and operates with the built-in battery when the operation voltage is not taken in the data processing device 1. The temperature sensor 32 is a thermal diode mounted on the motherboard and detects the temperature of a predetermined location in the data processing apparatus 1.

Cover sensors S1, S2, and S3 detect opening and closing of the covers A1, A2, and A3, respectively.
The latch circuit L1 is set when the cover opening is detected by any one of the cover sensors S1, S2, and S3, and functions to prevent the system from starting without the data processing apparatus 1 opening the cover. The latch circuit L2 is set when the cover opening is detected by any of the cover sensors S1, S2 and S3, supplies an ON signal to the power switch 42, and the supply of the ON signal is canceled by a reset operation from the CPU 20. To do. The power switch 42 is repeatedly turned on and off every time the power button 2 is pressed, and is turned on when an on signal is received from the latch circuit L2, and the output voltage of the uninterruptible power supply circuit 43 is set to the operating voltage of the data processing apparatus 1. This state is continued until the ON signal is released by resetting the latch circuit L2. The uninterruptible power supply circuit 43 rectifies the AC voltage of the commercial AC power supply 44, charges the rectified DC voltage to the internal battery, and converts the rectified DC voltage or the battery voltage into a predetermined level of DC voltage. And output.

The CPU 20 acquires, as a main function, information related to the security of the data processing device 1 when any one of the cover sensors S1, S2, S3 detects the opening of any of the covers A1, A2, A3. Control means are provided.
The process from opening the cover to starting the system will be described with reference to the flowchart of FIG.

  First, when any of the covers A1, A2, and A3 is opened while the system is not activated, the open state is detected by any of the cover sensors S1, S2, and S3 (YES in ST101). Along with this detection, the latch circuits L1 and L2 are set (ST102), and an ON signal is supplied from the latch circuit L2 to the power switch 42. Thereby, the power switch 42 is turned on, and the output voltage of the uninterruptible power supply circuit 43 is taken in as the operating voltage. That is, if commercial AC power supply 44 is turned on (YES in ST103), a DC voltage obtained by rectifying the AC voltage of commercial AC power supply 44 is taken in as an operating voltage (ST104). If commercial AC power supply 44 is cut off (NO in ST103), the battery in uninterruptible power supply circuit 43 is discharged, and the discharge voltage is taken in as an operating voltage (ST105). Then, the data processing apparatus 1 is activated by the taken operation voltage (system activation; ST106).

  Accompanying this system startup, the security information acquisition process shown in FIG. 5 is executed. The security information is information related to the security of the device, such as date, time, temperature, and a captured image of the CCD camera 4.

  First, the date and time are acquired from the RTC 31 (ST201), the temperature detected by the temperature sensor 32 is acquired (ST202), and the CCD camera 4 is activated to acquire the captured image (ST203). The acquired information is stored in the hard disk 29 as security information.

  When the security information acquisition processing is completed in this way, system termination processing is performed, and the latch circuit L2 is reset (ST204). By this reset, the supply of the ON signal to the power switch 42 is canceled and the power switch 42 is turned off. When the power switch 42 is turned off, the operation voltage is released and the operation of the data processing apparatus 1 is stopped.

  When the other cover is subsequently opened, the latch circuit L2 is set again, and the security information is acquired in the same manner as described above.

  On the other hand, once the latch circuit L1 is set, the latch circuit L1 maintains that state, and prohibits activation of the system except for activation for obtaining security information when the cover is opened. This prohibition prevents unauthorized activation.

  By confirming the security information acquired and stored in the hard disk 29, it is possible to accurately grasp the state when the covers A1, A2, and A3 are opened. Since security information is acquired each time the cover is opened, it is possible to accurately analyze in what order the covers A1, A2, and A3 are opened. Therefore, the subsequent safety measures can be enhanced. In addition, since the uninterruptible power supply circuit 43 is provided, the operating voltage can be obtained even when the commercial AC power supply 44 is cut off, and security information can be reliably acquired.

[2] Modifications Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, the input from the cover sensors S1, S2, and S3 may be stored in the hard disk 29 so as to be identifiable so that it can be specified which cover has been opened.

  Further, the installation position of the CCD camera 4 may be a position where the surrounding image can be taken even if it is not the base part A.

  Also, since the cover sensors S1, S2, and S3 detect the opening of the covers A1, A2, and A3 until the acquisition of security information, the person who has opened the cover is performing the photographing process by the CCD camera 4 and the like. In order not to be detected, if the cooling fan such as the CPU 20, various LEDs, the touch panel display and the like are not operated, the security can be further improved.

  Further, the CCD camera 4 may not be built in the data processing apparatus 1, and for example, a security camera system installed outside may be used. A security system using an external security camera will be described with reference to FIG. The security camera 50 and the camera server 51, and the camera server 51 and the data processing device 1 are connected to each other via a wired or wireless LAN so that the camera server 51 controls the security camera 50. And a recording memory 53 for recording the shot video.

  When opening of any one of the covers A1, A2, and A3 is detected by the cover sensors S1, S2, and S3, a signal that instructs the camera control unit 52 to take a picture is transmitted from the communication interface 30. Upon receiving this signal, the camera control unit 52 drives the security camera 50 to photograph the periphery of the data processing apparatus 1, and the photographed video is stored in the recording memory 53.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from the overall components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
