Description

  The present invention relates to a processing apparatus having a function of preventing unauthorized access.

There is a processing device such as a non-contact IC (Integrated Circuit) card that can store information from the outside and read the stored information from the outside while the device is periodically inserted.
Such a processing device is convenient because it does not require the device to be inserted or connected to a reader. However, on the other hand, there is a risk that the stored information may be accessed without the owner's knowledge, and security measures become an issue.

For example, if unauthorized access to a basic resident register card or an IC card used as a membership card is allowed, personal information such as user information may be leaked.
Alternatively, in the case of an IC card used as electronic money, there is a risk that the charged amount will be withdrawn due to unauthorized charging.

  For this reason, conventionally, security measures have been taken by strengthening mutual authentication.

  There is a mobile phone equipped with such a function as a non-contact IC card.

In the case of a mobile phone, if it is lost or stolen, the function cannot be used unless a password is set and the set password is entered so that the person who finds it cannot use it illegally. There is technology to do.
Japanese Patent Laid-Open No. 2003-060748

In the conventional security measures for contactless IC cards, when a device that accesses the security card is illegally manufactured, mutual authentication fails, so that unauthorized access can be prevented.
However, if it is illegally obtained by stealing a legitimate device, mutual authentication is successful and unauthorized access is possible.

Since the non-contact IC card can be accessed only from a relatively close distance, it is difficult to attempt unauthorized access even if a legitimate device is obtained illegally.
However, for example, in a situation such as a crowded train, it may be possible to approach an accessible distance. For example, there is a possibility that the IC card can be accessed if the accessing device is kept in the bag and brought close to another person's bag containing the IC card.

  In the case of a processing device that can input the operation of the owner such as a mobile phone, such unauthorized access can be prevented by setting a password and prohibiting the operation (so-called locked state).

However, if the lock state is set, when the owner who is the right holder wants to use the function, he / she has to input a password or the like every time.
Therefore, there is a problem that the owner rarely sets the locked state in practice.

  An object of the present invention is, for example, to solve the above-described problems and effectively prevent unauthorized access.

The processing apparatus according to the present invention includes:
An operation unit for performing a predetermined operation;
An operation input unit for inputting a release operation for canceling the operation of the operation unit;
A condition determination unit that determines that a permission condition for permitting the operation unit to perform a predetermined operation is satisfied when the operation input unit inputs a release operation;
When the condition determination unit determines that the permission condition is satisfied, an operation restriction unit that allows the operation unit to perform a predetermined operation; and
It is characterized by having.

  According to the present invention, since the operation of the operation unit is permitted only while the user inputs the release operation, there is no need to input a password or the like when the user wants the operation unit to operate. Can be operated easily. On the other hand, since the operation of the operation unit is not permitted in a state where it is put in a bag or the like, there is an effect that unauthorized access can be prevented.

Embodiment 1 FIG.
The first embodiment will be described with reference to FIGS.

  FIG. 1 is a hardware configuration diagram illustrating an example of a hardware configuration of a mobile communication terminal device 100 (an example of a processing device) according to this embodiment.

The state sensor 951 is connected to the open / close unit 950 of the mobile communication terminal device 100 and detects the open / close state of the mobile communication terminal device 100. For example, if the external shape of the mobile communication terminal device 100 is a slide type, it is detected whether the slide is open or closed. Alternatively, in the case of a folding type, it is detected whether it is in an expanded state or a closed state.
For example, an open / close state is detected by installing a micro switch in the open / close unit 950 of the mobile communication terminal device 100 and converting the open / close state of the mobile communication terminal device 100 into an energization / disconnection state of electricity. The detected opening / closing state is transmitted to the CPU 901 through the bus 902 as an electrical signal.

The brightness sensor 952 measures the brightness around the mobile communication terminal device 100. For example, the CPU 901 adjusts the luminance of the backlight of the display unit 920 based on the ambient brightness measured by the brightness sensor 952, and suppresses power consumption.
For example, a photodiode is installed outside the mobile communication terminal device 100, and ambient brightness is converted into a resistance value of the photodiode. The brightness sensor 952 detects this by applying a voltage to the photodiode.
The brightness sensor 952 is set in advance with a brightness as a reference for comparison, and a binary logic signal indicating whether the detected brightness is brighter or darker is an electrical signal via the bus 902. To the CPU 901.

The memory 983 is a non-volatile memory such as a flash memory, and stores data and programs.
The wireless unit 985 performs wireless communication with the outside via an antenna.

The non-contact IC card module 980 has a function as a non-contact IC card.
That is, the wireless unit 985 performs wireless communication with the outside via the antenna, transmits the contents of the memory 983, and stores information obtained from the outside in the memory 983. The CPU 981 prevents unauthorized access by performing mutual authentication with an external device for communication as necessary.

In addition, the non-contact IC card module 980 exchanges information with the CPU 901 of the mobile communication terminal device 100 via the interface unit 987.
The non-contact IC card module 980 may supply power from the power supply unit 960. However, the non-contact IC card module 980 can be driven by obtaining power from radio waves radiated from an external device, and thus is not supplied with power from the power supply unit 960. Can work.
Further, the non-contact IC card module 980 can disable the function as a non-contact IC card (locked state) by a command from the CPU 901.

In addition, arrows in the flowcharts described in the description of the embodiments described below mainly indicate data input / output, and data is recorded in a recording medium such as the memories 903 and 983 for the data input / output. . Alternatively, it is transmitted through a signal line or other transmission medium.

  In addition, what is described as “˜unit” in the description of the embodiment described below may be realized by firmware stored in the memories 903 and 983. Alternatively, it may be implemented by software alone, hardware alone, a combination of software and hardware, or a combination of firmware.

FIG. 2 is a block configuration diagram illustrating an example of a functional block configuration of the mobile communication terminal device 100 according to this embodiment.
The mobile communication terminal device 100 includes an operation input unit 110, a brightness measurement unit 121, a position determination unit 131, a condition determination unit 141, an operation restriction unit 151, a non-contact IC card function unit 180, and the like.

  The operation input unit 110 includes a key input unit 111, a touch input unit 112, an open / close state input unit 113, and the like.

The key input unit 111 determines whether or not the user presses the operation button 939 (the lock key 931, the release key 932, and other keys) on the operation panel 930. If the key is pressed, it is determined which key has been pressed, and the condition determination unit 141 is informed.
For example, when the operation button 939 is pressed, the operation panel 930 issues a signal corresponding to the pressed operation button, and the CPU 901 receives the signal via the bus 902.

The touch input unit 112 determines whether or not the user has touched the touch sensor of the operation panel 930, and notifies the condition determination unit 141.
For example, when a user touches a touch panel configured with a piezoelectric element or the like, a voltage corresponding to the pressure received by the touch panel is output. The operation panel converts this voltage into a signal to be transmitted to the CPU 901, and the CPU 901 receives the signal via the bus 902.

  The open / close state input unit 113 determines the open / closed state of the mobile communication terminal device 100 detected by the state sensor 951 and notifies the condition determination unit 141 of the open / closed state.

  The CPU 901 executes a program that constitutes a part of the operation input unit 110 and processes a signal received from the operation panel 930 or the state sensor 951 to determine whether the operation button 939 is pressed.

  The brightness measurement unit 121 inputs the ambient brightness measured by the brightness sensor 952 and transmits it to the condition determination unit 141.

  The position determination unit 131 determines the current position of the mobile communication terminal device 100 and notifies the condition determination unit 141 of the current position.

Based on the above input, the condition determination unit 141 determines whether to permit or prohibit the use of the non-contact IC card function of the non-contact IC card function unit 180.
That is, predetermined predetermined conditions are stored in the memory 903 or the like, and the CPU 901 executes a program constituting the condition determining unit 141 and stores the state input from the operation input unit 110 or the like in the memory 903 or the like. Apply to the condition and determine whether the condition is met.
Further, a table configured to be able to refer to the state to be set in the non-contact IC card function unit 180 using the current state of the non-contact IC card function unit 180 and the satisfied condition as an index is stored in the memory 903 or the like. If it is stored in advance and it is determined that the condition is satisfied, the state to be set in the non-contact IC card function unit 180 is read by referring to this table. The condition determining unit 141 notifies the operation limiting unit 151 of this.

The operation restriction unit 151 restricts the operation of the non-contact IC card function unit 180 based on the determination result of the condition determination unit 141.
That is, the CPU 901 executes a program constituting the operation restriction unit 151 and receives a state to be set in the non-contact IC card function unit 180 from the condition determination unit 141.
Then, a signal for instructing prohibition or permission of the operation is transmitted from the CPU 901 to the non-contact IC card module 980 via the interface unit 987.

The non-contact IC card function unit 180 realizes a function as a non-contact IC card by the non-contact IC card module 980.
The non-contact IC card function unit 180 includes a storage unit 183 realized by the memory 983 and the like.
The non-contact IC card function unit 180 communicates with an external device such as the non-contact IC card reader / writer 200 by the wireless unit 985. If security measures such as mutual authentication are performed and the access is legitimate, information stored in the storage unit 183 is transmitted, or information received from the non-contact IC card reader / writer 200 is stored in the storage unit 183.
However, when the non-contact IC card module 980 receives a signal for instructing prohibition of operation from the operation restriction unit 151, the above operation is not performed.
This is because when an operation prohibition signal is received, a part of the circuit in the non-contact IC card module 980 is logically disconnected (for example, an AND (logical product) element is inserted and one input of the AND element is inserted). If the operation enable signal (logical inversion of the operation disable signal) is input to the input, the output of the AND element will not change when the operation enable signal is not received. Also good.
Alternatively, a configuration may be adopted in which the operation is prohibited in terms of software by executing a program that processes a signal received by the CPU 981.

  Next, the operation will be described.

  FIG. 3 is a flowchart showing an example of the processing flow of the mobile communication terminal device 100 in this embodiment.

In S <b> 11, the key input unit 111 monitors the state of the operation buttons 939 such as the lock key 931, the release key 932, and other keys, detects that it has been pressed, and notifies the condition determination unit 141.
In S21, the condition determination unit 141 determines whether or not a predetermined condition is satisfied based on an input from the key input unit 111, and determines a state to be set in the non-contact IC card function unit 180. To do. If it is determined that the condition is satisfied, S22 is executed.
In S <b> 22, the operation restriction unit 151 receives a state to be set in the non-contact IC card function unit 180 from the condition determination unit 141 and sets it in the non-contact IC card function unit 180.
In S31, the non-contact IC card function unit 180 determines whether the state set by the operation restriction unit 151 is a locked state, a released state, or a temporarily released state. If it is determined that the release state or the temporary release state is set, S32 is executed.
In S32, the non-contact IC card function unit 180 performs processing based on the function as a non-contact IC card.

FIG. 4 shows a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In FIG. 4, when the contactless IC card function unit 180 is in the state shown in the upper column and the condition determination unit 141 determines that the condition of the left column is satisfied, the operation restriction unit 151 changes to the contactless IC card function unit 180. The state to be set is shown in the lower right part of the table.
Moreover, when maintaining a state as it is, it describes as "-".

  For example, the memory 903 or the like is stored in the table. The condition determination unit 141 includes a program for reading a state to be set from a table stored in the memory 903 or the like using the condition and state as an index.

The non-contact IC card function unit 180 has three states of “lock state”, “temporary release state”, and “release state” as the current state.
When the non-contact IC card function unit 180 is locked, the function of the non-contact IC card function unit 180 cannot be used even if there is an access from a regular non-contact IC card reader / writer 200.
When the non-contact IC card function unit 180 is temporarily released or released, the functions of the non-contact IC card function unit 180 can be used as usual.

  The state of the non-contact IC card function unit 180 is controlled by the operation restriction unit 151, and when the condition determination unit 141 determines that a predetermined condition is satisfied, the state of the non-contact IC card function unit 180 is changed.

  In this embodiment, there are four conditions that cause a change in the state of the non-contact IC card function unit 180: “lock key pressed” “release key pressed” “other key pressed” “no key pressed”.

  When the condition determination unit 141 determines that the lock key 931 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  When the condition determination unit 141 determines that the release key 932 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the release state.

  When the condition determining unit 141 determines that a key other than the lock key 931 and the release key 932 is pressed based on an input from the key input unit 111 in the locked state, the operation limiting unit 151 determines that the non-contact IC card is used. The function unit 180 is temporarily released.

  When the condition determination unit 141 determines that no key is pressed based on an input from the key input unit 111 in the temporary release state, the operation restriction unit 151 includes the non-contact IC card function unit 180. Set the state to the locked state.

  Therefore, when the user does not use the function as the non-contact IC card, if the user presses the lock key 931 and puts it in the locked state, even if the user has illegally obtained a genuine non-contact IC card reader / writer. Even a third party cannot illegally access a contactless IC card.

Further, when the user wants to use the function as a non-contact IC card, by pressing a key other than the lock key 931 and the release key 932, the user is temporarily released while the key is pressed, and the non-contact IC card. Can be used as a function.
When you have finished using the function, release the key you pressed, and it automatically returns to the locked state, making unauthorized access impossible again.

  As a result, the contactless IC card function is temporarily locked only when you use the contactless IC card function to check out at the cash register, pass through the ticket gate of the station, or present a membership card. Can be released.

  If the release key 932 is pressed to enter the release state, the function as a non-contact IC card can be used without pressing the key.

  As described above, since the lock state and the temporary release state can be switched by an extremely simple operation of pressing or not pressing the key, the user can easily use the lock function.

  Since there is no need to enter a security code to unlock the contactless IC card function, the contactless IC card function should be used instantly only when you want to use it with the contactless IC card function locked. Is possible.

  This is not only the effect that the operation is simple, but also the effect that the number of users who use the lock function increases because the operation is simple. As a result, unauthorized access to a contactless IC card becomes difficult, leading to a reduction in crimes such as electronic theft, which is also meaningful for society as a whole.

In this example, a temporary release state is established by pressing any key other than the lock key 931 and the release key 932. However, a temporary release key is provided, and temporary release is possible even if other keys are pressed. It is good also as a structure which does not do.
Then, even if the key is accidentally pressed by hitting something in the bag, it is not temporarily released, so the possibility of unauthorized access can be eliminated. In addition, the operability for the user is further improved.

Alternatively, the lock key 931 and the release key 932 may not be provided, and the lock state may be always set (a temporary release state only while the key is pressed).
By doing so, it is possible to prevent accidentally forgetting to enter the locked state, thereby eliminating the possibility of unauthorized access.

  In this example, the keys such as the lock key 931 and the release key 932 are independent keys. However, these keys can also be distinguished as one key by distinguishing them by how the keys are pressed (long press, double press, etc.). It may be a combination of a plurality of keys or a setting from a menu screen.

In recent years, an electronic money system using a non-contact IC card has been considered.
Non-contact IC cards are being standardized by ISO (International Organization for Standardization) 14443 and the like. In general, an IC is embedded in a plastic card, which is superior in terms of storage capacity and security compared to a magnetic card, and can be used for various purposes.
For this reason, it is possible to hold electronic money and use it for price settlement in a ticket ticket, automatic ticket gate for commuter passes, store terminals, vending machines, and the like. As electronic money, if a dedicated machine is used for filling, the balance can be increased by that amount. It can also be used to manage personal information such as membership cards using the same system.

Further, the non-contact IC card function is also being installed in a mobile communication terminal device represented by a mobile phone.
The non-contact IC card itself can transmit and receive data while being separated from a counterpart device relatively close by radio waves such as electromagnetic waves.
By combining this with a mobile communication terminal device that can communicate with a remote location, the IC can be accessed by accessing a server such as a bank on the network at any location within the range where radio waves from the base station can reach. It is possible to exchange information such as filling the balance in the card and adding points such as membership cards using a recording device at the store.

  As described above, as the uses and functions of the non-contact IC card are diversified, the necessity of security measures is further increased.

  In such a situation, it can be said that it is a very significant effect that the function as a non-contact IC card can be locked by an extremely simple operation.

The mobile communication terminal device described here is a mobile communication terminal device equipped with a non-contact IC card module, and has a function of temporarily unlocking the non-contact IC card function.
The operation for temporarily releasing the lock is an extremely simple operation in which a part of the main body operation unit is continuously pressed or touched, whereby the lock can be temporarily released. is there.

As described above, the portable communication terminal device described here includes a contactless IC card unit having a function of managing payment and user information, and is intended to prevent unauthorized access in a situation where a user normally uses it. It has a lock function, and has a means to set and release the lock function in a simpler way, so that unauthorized access to the non-contact IC card part can be made without sacrificing user convenience. It becomes possible to prevent.
In addition, unauthorized access to the non-contact IC card unit can be prevented more easily in accordance with the life scene of the user.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIGS. 1 to 3 and FIG.
The configuration of hardware and functional blocks of portable communication terminal device 100 (an example of a processing device) in this embodiment is the same as that described in Embodiment 1 with reference to FIGS. Is omitted.
Also, the processing flow of the mobile communication terminal device 100 is the same as that described with reference to FIG.

FIG. 5 shows a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In this embodiment, the conditions that cause the state of the non-contact IC card function unit 180 to change are “lock key pressed” “lock key long press” “release key pressed” “predetermined elapsed time from pressing the release key” There are four types of progress.

  When the condition determining unit 141 determines that the lock key 931 is pressed for a shorter time than the predetermined time based on the input from the key input unit 111, the operation limiting unit 151 changes the state of the non-contact IC card function unit 180. Set to locked state.

  When the condition determining unit 141 determines that the lock key 931 is continuously pressed for a predetermined time or more based on the input from the key input unit 111, the operation limiting unit 151 includes the non-contact IC card function unit 180. The state of is released.

  When the condition determination unit 141 determines that the release key 932 is pressed based on the input from the key input unit 111 in the locked state, the operation restriction unit 151 temporarily changes the state of the non-contact IC card function unit 180. Set to the release state.

  In the temporary release state, the condition determination unit 141 measures an elapsed time after the release key is pressed to enter the temporary release state. When the condition determination unit 141 determines that a time equal to or longer than a predetermined time has elapsed, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  Therefore, when the user does not use the function as the non-contact IC card, the user presses the lock key 931 to be in the locked state, and when the user wants to use the function as the non-contact IC card, the user presses the release key 932. Then, the temporary release state is set, and the function as a non-contact IC card is used.

  If the release key 932 is pressed once, it remains in the temporarily released state until a predetermined time elapses, so the user does not need to keep pressing the key.

  Further, when the predetermined time has elapsed, the locked state is automatically restored, so that unauthorized access is impossible.

  In this way, the temporary release state is set for a certain period of time after the release key is pressed, and then automatically returns to the locked state, so there is no need to keep pressing the key. Therefore, the user's operation is further simplified.

  Note that the time from when the release key is pressed to the temporary release state until the return to the locked state may be determined in advance, or the user may be able to set it according to preference.

  In this example, the elapsed time after the release key is pressed and temporarily released is measured, but the elapsed time after the release key is released may be measured.

The mobile communication terminal device described here is characterized in that a dedicated operation unit is provided for an operation for temporarily releasing the lock.
The operation for temporarily releasing the lock is an extremely simple operation of pressing or touching a part of the main body operation unit, whereby the lock can be temporarily released.
Furthermore, after a certain period of time has elapsed, it automatically returns to the locked state.

In S <b> 22, the operation restriction unit 151 receives a state to be set in the non-contact IC card function unit 180 from the condition determination unit 141 and sets it in the non-contact IC card function unit 180.
In S31, the non-contact IC card function unit 180 determines whether the state set by the operation restriction unit 151 is a locked state, a released state, or a temporarily released state. If it is determined that the release state or the temporary release state is set, S32 is executed.
In S32, the non-contact IC card function unit 180 performs processing based on the function as a non-contact IC card.

FIG. 9 illustrates a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In this embodiment, the conditions that cause the state of the non-contact IC card function unit 180 to change are “pressing the lock key”, “pressing the release key”, “opening and not using other functions”, “opening state” The other functions are being used in the "closed state".

  When the condition determination unit 141 determines that the lock key 931 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  When the condition determination unit 141 determines that the release key 932 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the release state.

  When the condition determination unit 141 determines that the lock state is in an open state based on an input from the open / close state input unit 113, the operation restriction unit 151 temporarily cancels the state of the non-contact IC card function unit 180. Put it in a state.

  When the condition determination unit 141 determines that the state is the temporary release state and the closed state based on the input from the open / close state input unit 113, the operation restriction unit 151 locks the state of the non-contact IC card function unit 180. Put it in a state.

  However, since it may be in an open state in order to use a function (for example, a telephone function or a game function) that is not a function as a non-contact IC card, the condition determination unit 141 determines whether another function is used. If it is determined that another function is used, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  Therefore, when the user does not use the function as the non-contact IC card, the user can press the lock key 931 to be in the locked state and close the portable communication terminal device 100 to be in the closed state. Unauthorized access is not possible.

Further, when the user wants to use the function as a non-contact IC card, the mobile communication terminal device 100 is opened to be in a temporary release state, and the function as the non-contact IC card can be used.
After using the function, if the mobile communication terminal device 100 is closed and put into the closed state, it returns to the locked state and unauthorized access becomes impossible.

In this way, since the lock state and the temporary release state can be switched by an extremely simple operation of opening and closing the mobile communication terminal device 100, the user can easily use the lock function.
In addition, it is considered that the operation of opening the mobile communication terminal device 100 when using the mobile communication terminal device 100 and closing the mobile communication terminal device 100 when used is a habit of the user, so there is very little possibility of forgetting to operate the device. Therefore, the user does not need to be aware that the lock function is used, and it becomes very easy to use.

  Note that the mobile communication terminal device described here includes a detection unit that detects an open / close state of the main body, and the lock is temporarily released depending on the open / closed state of the main body.

Embodiment 4 FIG.
The fourth embodiment will be described with reference to FIGS. 1, 2, 8, and 10. FIG.
The configuration of hardware and functional blocks of mobile communication terminal device 100 (an example of a processing device) in this embodiment is the same as that described in Embodiment 1 with reference to FIGS. Description is omitted.
Further, the processing flow of the mobile communication terminal apparatus 100 is the same as that described with reference to FIG.

FIG. 10 shows a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In this embodiment, the conditions that change the state of the non-contact IC card function unit 180 are “lock key pressed”, “release key pressed”, “open state before a predetermined elapsed time”, “open state” There are five states, “after a predetermined elapsed time” and “closed state”.

  When the condition determination unit 141 determines that the lock key 931 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  When the condition determination unit 141 determines that the release key 932 is pressed based on the input from the key input unit 111, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the release state.

  The condition determination unit 141 determines whether the mobile communication terminal device 100 is in an open state based on an input from the open / close state input unit 113. If the mobile communication terminal device 100 is in an open state, Measure elapsed time.

  In the locked state, the condition determining unit 141 determines whether or not it is in the open state. If it is in the open state, the condition determining unit 141 determines whether or not the elapsed time since the open state is shorter than a predetermined time. When the condition determination unit 141 determines that the elapsed time from the open state is shorter than the predetermined time, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the temporary release state.

  In the temporary release state, the condition determination unit 141 determines that it is in the closed state based on the input from the open / close state input unit 113, and determines that a predetermined time or more has passed since the open state is entered. In this case, the operation restriction unit 151 sets the state of the non-contact IC card function unit 180 to the locked state.

  Therefore, when the user does not use the function as the non-contact IC card, the user can press the lock key 931 to be in the locked state and close the portable communication terminal device 100 to be in the closed state. Unauthorized access is not possible.

Further, when the user wants to use the function as a non-contact IC card, the mobile communication terminal device 100 is opened to be in a temporary release state, and the function as the non-contact IC card can be used.
After using the function, if the mobile communication terminal device 100 is closed and put into the closed state, it returns to the locked state and unauthorized access becomes impossible.

  Also, even if the open state continues for a long period of time longer than a predetermined time, it automatically returns to the locked state, making unauthorized access impossible. For example, even when the mobile communication terminal device 100 hits something in a bag and accidentally becomes open, or when the phone function is used, it remains open for a long time. Unauthorized access can be prevented.

  Thus, even if the mobile communication terminal device 100 is in the open state, if it continues for a long time, it automatically returns to the locked state, so that unauthorized access can be prevented.

Embodiment 5. FIG.
A fifth embodiment will be described with reference to FIGS.

FIG. 11 is a diagram showing an example of the appearance of a non-contact IC card 300 (an example of a processing apparatus) in this embodiment.
The non-contact IC card 300 is not much different from a plastic card in appearance.
However, the touch sensor 953 is provided near the center of the surface.
The touch sensor 953 is arranged so as to be exactly at the position of the opening 410 when the non-contact IC card 300 is placed in the regular slot 400 or the like.
Thus, the user can touch the touch sensor 953 even when the non-contact IC card 300 is placed in the regular slot 400 or the like.

FIG. 12 is a hardware configuration diagram showing an example of the hardware configuration of the non-contact IC card 300 in this embodiment.
The non-contact IC card 300 includes a CPU 981, a memory 983, a wireless unit 985, a touch sensor 953, a brightness sensor 952, and the like.

The CPU 981 implements the functions described below and other functions as a non-contact IC card by executing a program stored in the memory 983 and the like.
The memory 983 is a non-volatile memory such as a flash memory, and stores programs executed by the CPU 981 and data.
The wireless unit 985 performs wireless communication with the outside via an antenna.

The touch sensor 953 detects that something has touched.
For example, when a user touches a touch panel configured with a piezoelectric element or the like, a voltage corresponding to the pressure received by the touch panel is output. The operation panel converts this voltage into a signal to be transmitted to the CPU 901, and the CPU 901 receives the signal via the bus 902.
This sensor detects contact only when a conductor such as a human body comes into contact with the touch sensor so that if something inadvertently touches the touch sensor in a bag or the like, the lock state does not change. May be.

  The brightness sensor 952 measures ambient brightness. The brightness sensor 952 can be realized by, for example, a photodiode. Although the brightness sensor 952 is not explicitly shown in FIG. 11, it can be measured near the touch sensor 953 and the ambient brightness can be measured even when the non-contact IC card 300 is placed in the regular slot 400 or the like. To place.

FIG. 13 is a block diagram showing an example of the functional block configuration of the non-contact IC card 300 in this embodiment.
The non-contact IC card 300 includes a touch input unit 312, a brightness measurement unit 321, a position determination unit 331, a condition determination unit 341, an operation restriction unit 351, an operation unit 380, a storage unit 383, and the like.

  The touch input unit 312 determines whether the user has touched the touch sensor 953 and notifies the condition determination unit 341 of it.

  The brightness measuring unit 321 measures the brightness around the non-contact IC card 300 and transmits it to the condition determining unit 341.

  The position determination unit 331 determines the current position of the non-contact IC card 300 and notifies the condition determination unit 341 of the current position.

  The condition determination unit 341 determines whether to permit or prohibit the use of the function of the operation unit 380 based on the above input.

  The operation restriction unit 351 restricts the operation of the operation unit 380 based on the determination result of the condition determination unit 341.

The operation unit 380 realizes an original function as a non-contact IC card.
The operation unit 380 includes a storage unit 383 realized by the memory 983 and the like.
The operation unit 380 communicates with an external device such as the non-contact IC card reader / writer 200 by the wireless unit 985. If security measures such as mutual authentication are performed and the access is authorized, information stored in the storage unit 383 is transmitted, or information received from the non-contact IC card reader / writer 200 is stored in the storage unit 383.

  Next, the operation will be described.

  FIG. 14 is a flowchart showing an example of the processing flow of the non-contact IC card 300 in this embodiment.

In S <b> 12, the touch input unit 312 detects whether or not the user has touched the touch sensor 953 and notifies the condition determination unit 341 of it.
In S <b> 21, the condition determining unit 341 determines whether or not a predetermined condition is satisfied based on an input from the touch input unit 312, and determines a state to be set in the operation unit 380. If it is determined that the condition is satisfied, S22 is executed.
In S <b> 22, the operation restriction unit 351 receives a state to be set in the operation unit 380 from the condition determination unit 341 and sets it in the operation unit 380.
In S31, the operation unit 380 determines whether the state set by the operation restriction unit 351 is a locked state or a temporarily released state. If it is determined that the state is temporarily released, S32 is executed.
In S32, the operation unit 380 performs processing based on the function as a non-contact IC card.

  In FIG. 15, in this embodiment, the condition determination unit 341 reads out the state to be set in the operation unit 380 based on the condition determined by the condition determination unit 341 and the current state of the operation unit 380. It is a figure which shows an example of the content of the table for this.

The operation unit 380 has two states of “lock state” and “temporary release state” as the current state.
When the operation unit 380 is in a locked state, the function of the operation unit 380 cannot be used even if there is an access from a regular non-contact IC card reader / writer 200.
When the operation unit 380 is temporarily released, the function of the operation unit 380 can be used as usual.

  The state of the operation unit 380 is controlled by the operation restriction unit 351, and when the condition determination unit 341 determines that a predetermined condition is satisfied, the state of the operation unit 380 is changed.

  In this embodiment, there are two conditions that cause the state of the operation unit 380 to change: “touching the touch sensor” and “not touching the touch sensor”.

  When the condition determination unit 341 determines that a human body or the like is touching the touch sensor based on the input from the touch input unit 312, the operation restriction unit 351 sets the state of the operation unit 380 to a temporarily released state.

  When the condition determination unit 341 determines that the human body or the like is not touching the touch sensor based on the input from the touch input unit 312, the operation restriction unit 351 sets the state of the operation unit 380 to the locked state.

  Therefore, when the non-contact IC card 300 is put in a bag or the like, it automatically becomes locked and unauthorized access is impossible.

  Further, since the user uses the function of the non-contact IC card 300, if the non-contact IC card 300 is taken out while being put in the regular slot 400 or the like, a finger or the like touches the touch sensor 953, and the function is temporarily released. Can be used.

  As described above, the lock state and the temporary release state are automatically switched depending on whether the finger touches the touch sensor 953 or not, so that the user can use it without being aware of the lock function, and unauthorized access. Effect of preventing.

In this embodiment, it is assumed that a non-contact IC card is used in an existing regular slot, etc., and most of the existing regular slots have an opening in the center. The touch sensor 953 is not necessarily located near the center although it is arranged in the vicinity.
When the user has a non-contact IC card, it is preferable to place it in an unconscious place because the user is less conscious of the lock function.

  Further, as described in Embodiment Mode 2, a configuration in which the touch sensor 953 is touched and a certain period of time elapses may be temporarily released.

Embodiment 6 FIG.
The sixth embodiment will be described with reference to FIG. 1, FIG. 2, FIG. 16, and FIG.
The configuration of hardware and functional blocks of mobile communication terminal device 100 (an example of a processing device) in this embodiment is the same as that described in Embodiment 1 with reference to FIGS. Description is omitted.

The brightness measurement unit 121 inputs the ambient brightness measured by the brightness sensor 952 and transmits it to the condition determination unit 141.
The CPU 901 executes a program that forms a part of the brightness measurement unit 121 on the signal received from the brightness sensor via the bus 902 and processes the signal received from the brightness sensor 952, thereby Judge the brightness.

  FIG. 16 is a flowchart showing an example of the processing flow of the mobile communication terminal device 100 according to this embodiment.

In S <b> 14, the brightness measuring unit 121 measures the ambient brightness and transmits it to the condition determining unit 141.
In S <b> 21, the condition determination unit 141 determines whether or not a predetermined condition is satisfied based on an input from the brightness measurement unit 121, and sets a state to be set in the non-contact IC card function unit 180. decide. If it is determined that the condition is satisfied, S22 is executed.
In S <b> 22, the operation restriction unit 151 receives a state to be set in the non-contact IC card function unit 180 from the condition determination unit 141 and sets it in the non-contact IC card function unit 180.
In S31, the non-contact IC card function unit 180 determines whether the state set by the operation restriction unit 151 is a locked state or a temporarily released state. If it is determined that the state is temporarily released, S32 is executed.
In S32, the non-contact IC card function unit 180 performs processing based on the function as a non-contact IC card.

FIG. 17 illustrates a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In this embodiment, there are two conditions that cause the state of the non-contact IC card function unit 180 to change: “the surrounding is bright” and “the surrounding is dark”.

  When the condition determining unit 141 determines that the ambient brightness of the mobile communication terminal device 100 is brighter than the predetermined brightness based on the input from the brightness measuring unit 121, the operation limiting unit 151 includes the non-contact IC card function. The state of the unit 180 is temporarily released.

  When the condition determining unit 141 determines that the ambient brightness of the mobile communication terminal device 100 is darker than the predetermined brightness based on the input from the brightness measuring unit 121, the operation limiting unit 151 includes the non-contact IC card function. The state of the unit 180 is set to the locked state.

  Therefore, when the mobile communication terminal device 100 is put in a bag or the like, the surroundings are dark, so that the mobile communication terminal device 100 is automatically locked and unauthorized access is impossible.

  In addition, since the user uses the function as a non-contact IC card, when the mobile communication terminal device 100 is taken out, the surrounding area becomes bright, so that the user automatically enters a temporary release state, and the function as the non-contact IC card can be used. it can.

For example, there is a risk that unauthorized access to the function as a non-contact IC card may be attempted in places where a relatively large number of other people are in close proximity, such as in a train or a movie theater. However, as long as the configuration is such that the lock state is obtained when the surroundings are dark, it is only necessary to keep the mobile communication terminal device 100 in a bag or the like in such a place.
Since this is a very natural operation, the user does not need to be aware of the lock function at all.

  As described above, the lock state and the temporary release state are automatically switched depending on whether the surroundings are bright or dark, so that the user can use the lock function without being aware of the lock function, thereby preventing unauthorized access. .

  Here, the brightness sensor 952 is conventionally included in the mobile communication terminal device 100 in order to adjust the luminance of the backlight of the display unit 920, for example. Alternatively, a CCD (Charge Coupled Device) light receiving unit for a camera function provided in the mobile communication terminal device 100 may be used as a brightness sensor.

  Therefore, it is not necessary to add new parts in order to control the lock function based on the ambient brightness, and there is an advantageous effect in that the manufacturing cost of the mobile communication terminal device 100 can be reduced and the size can be reduced.

  Note that the predetermined brightness as a reference for comparison may be determined in advance or may be changed according to the time zone. That is, since the inside of the bag is bright to some extent during the daytime, it is preferable to make the reference brightness brighter, and conversely, the outside is dark at night.

  Further, in this embodiment, only the ambient brightness is used as a determination criterion. However, the lock state may be switched in combination with the determination criterion described in the first to fourth embodiments. If it does so, the exact operation | movement according to a condition can be performed and it is preferable.

  For example, the configuration may be such that the surroundings are bright and the temporary release state is set only while the release button is pressed. By doing so, for example, even when the portable communication terminal device 100 is stored in a relatively bright place such as a pocket of a shirt, unauthorized access can be prevented, which is preferable.

  Or it is good also as a structure made into a temporary cancellation | release state only when the circumference | surroundings are bright and it is an open state. By doing so, the mobile communication terminal device 100 can be temporarily released by an extremely natural operation of taking out and opening the mobile communication terminal device 100, but unauthorized access can be made even if the bag is accidentally opened. This can be prevented and is preferable.

  Alternatively, the lock state and the release state are switched by operating the lock key 931 or the like, and in the release state, the function as the non-contact IC card may not be locked even if the above determination criterion is not satisfied. By doing so, by releasing the lock function in a place known to be safe, such as in a company, the function as a non-contact IC card can be used even if the mobile communication terminal device 100 is left, preferable.

  In this embodiment, the mobile communication terminal device has been described. However, the non-contact IC card described in Embodiment 5 can also be configured to switch the lock state according to the ambient brightness. In this case, the lock state may be switched in combination with the determination criterion described in the fifth embodiment.

  For example, it may be configured to be in a temporarily released state only when the periphery of the non-contact IC card is bright and touches the touch sensor. By doing so, for example, even when a non-contact IC card is stored in a relatively bright place such as a shirt pocket, unauthorized access can be prevented, which is preferable.

Note that the mobile communication terminal device described here has a light intensity detection unit and has a function of temporarily releasing the lock when the surrounding light intensity is a certain level or more.
As a result, the lock of the non-contact IC card function can be temporarily released without any special operation by the user.

Embodiment 7 FIG.
The seventh embodiment will be described with reference to FIG. 1, FIG. 2, FIG. 18, and FIG.
The configuration of hardware and functional blocks of mobile communication terminal device 100 (an example of a processing device) in this embodiment is the same as that described in Embodiment 1 with reference to FIGS. Description is omitted.

  The position determination unit 131 determines the current position of the mobile communication terminal device 100.

As a form of use of a non-contact IC card, it is used as a company employee ID card to manage entry / exit inside the company or restrict rooms that can be entered according to the employee's status.
There is also a system in which a non-contact IC card is used as a commuter pass or prepaid ticket, and a fare is automatically calculated and collected when passing through a ticket gate of a station.

  By using such a non-contact IC card function, it is possible to know where the mobile communication terminal device 100 is currently located.

For example, when a commuter pass function of a non-contact IC card or a prepaid ticket is used to enter the station from the ticket gate of the station, it can be determined that the mobile communication terminal device 100 is in the station premises or in the train.
Thereafter, when the above function is used to go out of the ticket gate of the station, it can be determined that the mobile communication terminal device 100 is outside the station.

  The same applies when entering or leaving the company using the employee ID function of the contactless IC card.

Further, as a usage form of a non-contact IC card, there is a system used as an entrance ticket for a movie theater or the like.
In such a usage form, for example, when a movie ticket is purchased using the electronic money function of the non-contact IC card, information on the purchased ticket is recorded on the non-contact IC card. If this is used when entering a movie theater, it can be used as it is.

Therefore, if this function is used to enter the movie theater, it can be determined that the mobile communication terminal device 100 is in the movie theater.
After that, even if it is possible to leave the movie theater without using the non-contact IC card function, if the movie show time and show time are known, the time when the user will leave the movie theater can be predicted. Therefore, when the time has passed, it is determined that the mobile communication terminal device 100 has left the movie theater.

  The position determination unit 131 determines that the function as the non-contact IC card as described above is used, and determines the current position of the mobile communication terminal device 100 based on the function.

  Note that the position determination unit 131 may determine the current position of the mobile communication terminal apparatus 100 using, for example, a GPS (Global Positioning System) function of the mobile communication terminal apparatus 100. This is preferable because the current position of the mobile communication terminal device 100 can be determined even when the non-contact IC card function is not used.

  FIG. 18 is a flowchart showing an example of the flow of processing of the mobile communication terminal device 100 in this embodiment.

In S <b> 15, the position determination unit 131 determines the current position of the mobile communication terminal device 100 by the method described above, and notifies the condition determination unit 141 of the current position.
In S21, the condition determining unit 141 determines whether or not a predetermined condition is satisfied based on an input from the position determining unit 131, and determines a state to be set in the non-contact IC card function unit 180. To do. If it is determined that the condition is satisfied, S22 is executed.
In S <b> 22, the operation restriction unit 151 receives a state to be set in the non-contact IC card function unit 180 from the condition determination unit 141 and sets it in the non-contact IC card function unit 180.
In S31, the non-contact IC card function unit 180 determines whether the state set by the operation restriction unit 151 is a locked state or a temporarily released state. If it is determined that the state is temporarily released, S32 is executed.
In S32, the non-contact IC card function unit 180 performs processing based on the function as a non-contact IC card.

FIG. 19 shows a state to be set in the non-contact IC card function unit 180 based on the condition determined by the condition determination unit 141 and the current state of the non-contact IC card function unit 180 in this embodiment. It is a figure which shows an example of the content of the table for the condition judgment part 141 to read.
In this embodiment, there are two conditions that cause the state of the non-contact IC card function unit 180 to change: “the current position is in the station premises / in the train” and “the current position is other than the above”.

When the condition determination unit 141 determines that the mobile communication terminal device 100 is in the station premises or in the train based on the input from the position determination unit 131, the operation restriction unit 151 changes the state of the non-contact IC card function unit 180. Set to locked state.
In addition, since it is necessary to use the function of the non-contact IC card function unit 180 to get out of the ticket gate of the station, only the commuter pass function (or prepaid ticket function) can be used even in the locked state. (E.g. electronic money function or ID card function) is prohibited.

  When the condition determination unit 141 determines that the mobile communication terminal device 100 is in a place other than the above based on the input from the position determination unit 131, the operation restriction unit 151 temporarily changes the state of the non-contact IC card function unit 180. Set to the release state.

  Therefore, when the function as a non-contact IC card of the mobile communication terminal device 100 is used as a commuter pass or a prepaid ticket, when entering a station through a ticket gate, it is automatically locked and illegal. Access is impossible.

  After that, when the function as the non-contact IC card of the mobile communication terminal device 100 is used as a commuter pass or a prepaid ticket and passes the ticket gate and goes out of the station, it automatically enters a temporary release state, Other functions as a contact IC card can be used.

  For example, there is a risk that unauthorized access to the function as a non-contact IC card may be attempted in places where a relatively large number of other people are in close proximity, such as in a train or a movie theater. However, if a commuter pass function or the like of a non-contact IC card is used, it is automatically locked in such a place, so that the user does not need to be aware of the lock function.

  In this way, the current position is determined, and the lock state and temporary release state are automatically switched based on the determined current position, so that the user can use it without being aware of the lock function, and unauthorized access Effect of preventing.

  Further, since the current position is determined based on the use of the function as a non-contact IC card, it is not necessary to add a special device. Further, it is not necessary to prepare map information separately, and it is not affected by positioning errors.

Note that, based on the determined current position, the use of a part of the function as the non-contact IC card may be permitted and the part may be prohibited.
For example, only the commuter pass function (or prepaid ticket function) is allowed in the station premises and trains, and some functions are allowed in other general places, but some functions are prohibited. The conditions may be finely divided such as permitting all functions.

  In the future, the number of scenes where the non-contact IC card function can be used is expected to increase further. If the opportunity to use the non-contact IC card function in the life increases, the types of the current position that can be determined based on it increase. For this reason, it is possible to set various conditions, permit only the function suitable for the place among the functions as the non-contact IC card, and prohibit other functions. In this way, the possibility of unauthorized access is further reduced, and safety is increased.

  In this embodiment, only the current position is used as a determination criterion. However, the lock state may be switched in combination with the determination criterion described in each of the above embodiments. If it does so, the exact operation | movement according to a condition can be performed and it is preferable.

For example, if you are in a station or train, if the surroundings are bright, use only the commuter pass function (or prepaid ticket function). If the surroundings are dark, include the commuter pass function (or prepaid ticket function). All functions are prohibited.
This is because when it is necessary to use the commuter pass function (or the prepaid boarding ticket function) in order to exit the ticket gate, the surroundings become bright because the mobile communication terminal device 100 is taken out of the bag or the like.
Alternatively, all functions are prohibited when in a station premises or on a train, but may be configured to be temporarily released only while the user is pressing the release button.
This is preferable because information on commuter passes and the like is not read out illegally in a train or the like.

  In addition, it is possible to set three cases in which the user is always in the locked state, always in the released state, or automatically switched between the locked state and the released state depending on the conditions such as the location. May be.

  The mobile communication terminal device described here is characterized in that it is locked or unlocked when a non-contact IC card is used under certain conditions.

Unauthorized access is likely to occur in situations where you are in contact with someone else in red for a certain amount of time, specifically when you are on a train or watching a movie or museum Is done.
In such a case, since the mechanism is automatically locked, the convenience for the user is further enhanced.

  At this time, if the user can set whether or not to use this function (lock reservation function), for example, the user can select whether or not to lock the contactless IC card function when passing through a ticket gate of a station. Is possible.

  Even when this function is used, the lock temporary release function may be usable.

  In this way, the user can prevent unauthorized access without impairing the convenience of the contactless IC card function. As a result, the security of the non-contact IC card is enhanced and the user can use it safely, so that the portable communication terminal device with the non-contact IC card can be widely used.
