Technical field

[0001] The present invention relates to a function use restriction method, a wireless communication terminal and a function use restriction program of a wireless communication terminal, and in particular, various functions such as browsing of personal information inside a mobile phone and a money payment function using a mobile phone. The present invention relates to a function use restriction method, a function use restriction program, and a wireless communication terminal for restricting the use of a password using a personal identification number.

Background art

In recent years, wireless communication terminals for performing wireless communication have become widespread. In particular, mobile phone terminals equipped with functions as telephones (hereinafter simply referred to as mobile phones) are not only convenient for making and receiving calls at any time, but also have high functionality and low price. With the expansion of the calling area, the spread rate is remarkable.

[0003] A cellular phone can transmit and receive information to and from other telephones by performing wireless communication with radio wave transmitting and receiving base stations installed in various places. That is, in order to make and receive calls and calls, as shown in FIG. 5, the mobile phone 100 can transmit and receive radio waves to and from the base station 101 (so-called call area or area) A1 Need to be in.

[0004] On the other hand, when the mobile phone 100 is in a range in which wireless communication with the base station 101 is not possible (so-called out-of-service area) A2, the mobile phone 100 makes a call or call with another phone. I cannot make incoming calls. However, the base station 101 is installed in various places, and the number of installed base stations is increasing, so the out-of-service area A2 is decreasing year by year!

[0005] Some mobile phones 100 have a function for transmitting / receiving character messages such as e-mail and an Internet connection function in addition to the above-described call function. Transmission / reception of information using these functions is also realized by wireless communication with the base station 101.

[0006] In addition, the owner of the mobile phone 100 (authorized user) sets itself so that wireless communication with the base station is impossible so as not to make and receive calls in hospitals and trains. Do It has a base station communication blocking function (so-called offline mode), a personal information recording function that registers and records phone book information and owner profile information, and many mobile phones 100 are also available.

. In addition, recently, mobile phones are used for purchasing goods at convenience stores and vending machines.

A method is also realized in which the purchase price of goods is settled by transmitting and receiving personal identification information, billing information, etc. by wireless communication between 100 and a specific communication device. In this way, the mobile phone 100 is already a personal information management tool, information communication tool that is not just a telephone.

Or, it has become a function as a money management tool.

[0007] Under such circumstances, it is important how to protect personal information, communication information, and settlement information by the mobile phone 100. Some recent mobile phones 100 have an information protection function. is there. This information protection function is a function that prevents a predetermined function from being used unless collation information such as a password is input. Here, the predetermined functions include, for example, a telephone book 'personal profile · personal information display function such as images, text message transmission, received content display function, telephone call · text message transmission' Internet connection etc. information transmission function, goods A payment function at the time of purchase can be considered.

[0008] However, when the information protection function is enabled, the owner of the mobile phone 100 needs to input a personal identification number each time when displaying personal information or making a payment, which is very troublesome and impairs operability. There is a problem that it will be. Therefore, the owner often disables the information protection function of the mobile phone 100!

[0009] Then, if the mobile phone 100 is dropped or misplaced, there is a risk that personal information, payment information, etc. may be misused by a third party who has found it. For such a case, a remote operation function for enabling the information protection function by remote operation has already been realized. This remote operation function is, for example, a function that enables the information protection function by performing a predetermined operation after calling the mobile phone 100 from another telephone. Even if the mobile phone 100 is dropped or misplaced while the information protection function is disabled, the information protection function can be set to be effective by the remote control function. It is safe to prevent being used. Disclosure of the invention

Problems to be solved by the invention [0010] However, the remote operation function is a function realized by placing a call to the mobile phone 100 from another telephone, for example, and therefore the mobile phone 100 needs to be in a state in which a call can be received. Therefore, as shown in FIG. 6, when the mobile phone 100 is in the out-of-service area A2, there is a problem that the remote operation function cannot be used and personal information is used by a third party.

[0011] Further, as shown in FIG. 7, even when the mobile phone 100 is in the coverage area A1, the remote control function cannot be used if the mobile phone 100 is set to the offline mode. Therefore, if a malicious third party normally sets the mobile phone 100 to the offline mode and uses the mobile phone 100 only to cancel the offline mode, the owner It becomes almost impossible to prevent the three parties from browsing the information in the mobile phone 100 and using the mobile phone 100.

Therefore, the present invention provides a function use restriction method and a function use restriction program for a wireless communication terminal that can effectively prevent the use of personal information and the like by a third party without substantially impairing the operability by the owner.

FIG. 1 is a block diagram showing an outline of the internal configuration of a mobile phone terminal (hereinafter referred to as a mobile phone) 1 as a wireless communication terminal according to Embodiment 1 of the present invention. This mobile phone 1 has a display unit 3, an operation key part 4, a fingerprint sensor 5 as an authentication information detection unit 5, an antenna 6, a speaker (not shown), and a microphone (not shown) outside the housing 2. is doing. In addition, the housing 2 includes a wireless communication unit 7, a memory 8 as an information recording unit, an electronic money IC 9 for fee settlement, and a computer 10 as a control unit.

[0033] The display unit 3 is configured by, for example, a liquid crystal display member (LCD) and the like, and can display various character numbers and images such as time, telephone number, character message, and digital photo image. The operation key section 4 is used by the user to make a call or enter a text message. Normally, the number buttons 0 to 9, the 〃 # 〃 button, the 〃 * 〃 button, the power button, and the call button are used. In addition to the buttons, various function buttons are arranged. The operation key unit 4 is also used for inputting a preset password.

The fingerprint sensor 5 inputs fingerprint information as biometric information for user authentication. When the owner of the cellular phone 1 registers his / her fingerprint information in advance, it is recorded in the information memory 8 as authentication information. When the user inputs the fingerprint information to the fingerprint sensor 5 when the mobile phone 1 needs to input the verification information to be verified, the computer 10 functioning as the authentication processing means 1 Oe The fingerprint information registered in the fingerprint information memory 8 is collated.

[0035] In the first embodiment, fingerprint information is used as biometric information, and the fingerprint sensor 5 is used as an authentication information detection unit. Other biometric information includes voiceprint information, iris information, intravascular blood vessel information, face Information can be considered. Depending on the biometric information, the mobile phone 1 should have an authentication information detector such as a microphone or camera.

As the authentication information, not only biometric information but also a personal identification number can be used. It is also possible to use a combination of a password and biometric information. The password can be entered as a multi-digit number or alphanumeric characters by operating the operation key section 4.

[0037] The wireless communication unit 7 is for the mobile phone 1 to perform wireless communication with an external device. Radio control means 1 Based on the radio control signal generated by the computer 10 functioning as Od! / ヽ, the radio communication unit 7 generates radio waves and the antenna 6 emits radio waves. . The radio wave received by the antenna 6 is detected / amplified by the radio communication unit 7 and is subjected to signal analysis (information processing) by the computer 10 functioning as the radio control means 10d.

[0038] In addition to the base station 20 (see Fig. 3), a specific communication device may be considered as an external device that performs wireless communication with the mobile phone 1. The mobile phone 1 and the base station 20 perform information communication such as telephone information, text message information, and Internet connection information, which are services provided mainly by telephone companies. On the other hand, as a specific communication device, a payment device having a fee payment function is conceivable, which is installed in a convenience store, for example, in a vending machine or an automatic ticket gate device of a station. The mobile phone 1 can perform wireless communication (specific wireless communication) with these settlement devices without going through the base station 20, that is, even in the out-of-service area A2. This makes it possible to make payments for purchased goods and boarding fares. Various information in the electronic money IC9 (for example, personal identification information, account information, balance information, etc.) is used for fee settlement.

The memory 8 records various information in the cellular phone 1. Personal information such as the owner's personal profile information, phone book information, telephone charge information, and text message transmission / reception contents are also recorded in this memory 8.

[0040] The computer 10 is for controlling the overall functions and operations of the mobile phone 1, and includes a specific function realization means 10a, a base station communication blocking means 10b, a function use restriction means 10c, a radio control means 10d, It has a function as the authentication processing means 10e. In addition, the function unavailable means 10f for selectively or totally preventing various functions of the mobile phone 1 from being used as a remote control means 10g for enabling the function unavailable means by remote operation It also has a function. Furthermore, it also has a function as an application execution means 10h for executing various applications such as a telephone function, a text message transmission / reception function, an Internet connection function, and a telephone directory editing function.

[0041] The specific function refers to a display function for displaying the owner profile information, telephone directory information, and text message transmission / reception contents as personal information on the mobile phone 1, and a payment device for performing payment with electronic money. The function to perform wireless communication (specific wireless communication function) is included. That is, it is a function related to information that should be protected by the function use restriction means 10c as personal information and payment information. The specific function realization means 10a realizes these specific functions by a program inside the computer 10.

[0042] The base station communication cut-off means 10b implements a base station communication cut-off function (so-called offline mode) without performing radio communication with the base station 20 even when the mobile phone 1 is in the coverage area A1. Is. For example, the user sets the offline mode when he / she does not want to receive an incoming call to the mobile phone 1 in a hospital or train. In that case, even when the radio communication unit 7 of the mobile phone 1 detects the transmission radio wave from the base station 20 via the antenna 6, the base station communication blocking means 10b is connected to the base station 20 by the radio control means 10d. Prohibit wireless communication.

[0043] The function use restriction means 10c allows the user of the mobile phone 1 to use the specific function. It is limited under certain conditions. This function use restriction means 10c determines whether or not the mobile phone 1 is capable of wireless communication with the base station 20. When wireless communication with the base station 20 is possible, input of verification information is not required when using the specific function. When wireless communication with the base station 20 is impossible, the specific function is used. At that time, input of verification information is requested.

Specifically, the function use restriction unit 10c determines whether or not radio communication with the base station 20 is possible based on the information of the radio communication unit 7 and the radio control unit 10d. If it is determined that wireless communication with the base station 20 is not possible, the specific function realization means 10a performs a specific function based on the user's operation before the specific function realization means 10a executes the specific function. An information input request is displayed, and the fingerprint information input from the fingerprint sensor 5 or the security code input from the operation key unit 4 (these are verification information) and the authentication information recorded in the memory 8 are authenticated. Verification is performed by the processing means 10e.

[0045] As a result of the collation, if the match between the collation information and the authentication information is confirmed, the function use restriction means 1 Oc allows the specific function realization means 10a to execute the specific function, but if the coincidence is not confirmed. Do not allow execution of specific functions.

[0046] When wireless communication with the base station 20 is possible, the function use restriction unit 10c does not request input of verification information even when using a specific function. Here, the state in which wireless communication with the base station 20 is impossible means that the mobile phone 1 is in the out-of-service area A2, and the base station communication blocking function (so-called , Offline mode) is set and wireless communication with the base station is not possible. When the mobile phone 1 is released from the offline mode, the function use restriction unit 10c requests the user to input verification information.

[0047] The function unusable means 10f makes the function of the mobile phone 1 selectively or totally unavailable. When the unavailable setting by the function unavailable means 10f is validated, input of verification information is required to use a predetermined function set in advance. However, when this unusable setting is invalidated, the function unusable means 10f does not request input of verification information when using any function of the mobile phone 1. That is, when the user uses the mobile phone 1, the user cannot input the verification information using the function unavailable means 10f. Is never required.

[0048] The remote control means 10g makes the unavailable setting effective by remote operation. Specifically, even when the mobile phone 1 is in the coverage area A1 and the unavailable setting by the function unavailable means 10f is invalidated, it is possible to call the other mobile phone 1 to the mobile phone 1. The unusable setting can be effectively changed by performing an operation such as performing a predetermined operation.

[0049] Next, function use restrictions in the mobile phone 1 according to the embodiment of the present invention will be described with reference to the flowchart shown in FIG.

[0050] The user registers authentication information in advance when using the mobile phone 1 (step 1). In step 1, the authentication information registered in step 1 is recorded in memory 8. In step 2, whether or not the unusable setting is effective or not is determined, and if the unusable setting of the mobile phone 1 is enabled by the user, it is determined whether or not the specific function is used ( Step 3). If it is determined in step 3 that the specific function is not used, the function operation of the mobile phone can be continued. If it is determined in step 3 that a specific function is used, the function unavailable means 10f requests input of collation information (step 4). In this embodiment, a case where a specific function such as a personal information display function or a settlement function is selected will be described.

[0051] When verification information is input from the fingerprint sensor 5 or the operation key unit 4 by the user, verification information and verification information are verified (step 5). Yes (step 12). On the other hand, if it is determined in step 5 that the two information do not match, the specific function cannot be used and the collation information is requested again (step 4). It is possible to further protect the information by configuring the mobile phone 1 so that it cannot be turned on for a certain period of time after it has been repeatedly input for the verification information a predetermined number of times, or can only be canceled at a predetermined service store. Become effective.

[0052] When it is determined in step 2 that the unavailable setting of the mobile phone 1 is invalid, it is determined whether or not the mobile phone 1 is set to the offline mode (step 6). If offline mode is set in step 6, whether the mobile phone 1 is in the coverage area A1 or out of coverage area A2 In step 4, the function usage restriction means 10c requests the input of verification information. When the user inputs the verification information from the fingerprint sensor 5 or the operation key unit 4, the verification information and the verification information are verified (step 5). If the two information match, the specific function can be used (step 5). 12). On the other hand, if the two information do not match, the specific function cannot be used, and input of verification information is requested again (step 4). FIG. 3 shows a state in which the offline mode is set for the mobile phone 1 in the coverage area A1.

[0053] When the offline mode is canceled (step 7), input of verification information is requested (step 8), verification information and verification information are verified (step 9), and both information matches. And offline mode is released (step 10). On the other hand, if both information do not match in step 9, the offline mode is not canceled and the input of collation information is requested again (step 8). Thus, for example, if a third party who has picked up the mobile phone 1 cancels the offline mode only for a short time and uses a specific function while avoiding remote operation by the owner, malicious use can be prevented.

[0054] If the offline mode is not set in step 6 or the offline mode is canceled in step 10, whether mobile phone 1 is in range A1, ie, mobile phone 1 and base station A determination is made as to whether or not radio communication with 20 is possible (step 11). When the mobile phone 1 is in the area A1 in step 11, the collation information input request by the function use restriction means 10c is not made when using the specific function. Therefore, the user can use the specific function without entering the verification information in the area A1 (step 12). This eliminates the need for troublesome collation information input, so it is convenient and convenient. In addition, if the user is a third party who has picked up the mobile phone 1, the mobile phone owner can use the remote control means 10g to enable the unavailable setting, so it is safe.

[0055] When the mobile phone 1 is in the out-of-service area A2 (see Fig. 4), when the user uses the specific function, the function use restriction means 10c requests input of verification information (step 4). When the user inputs the verification information from the fingerprint sensor 5 or the operation key unit 4, the verification information and the verification information are verified (step 5), and if the two information match, the specific function can be used (step 12). ). On the other hand, if the information does not match, the specific function cannot be used, and it is checked again. You are prompted for information (step 4).

[0056] By making the computer 10 in the mobile phone 1 function as the function use restriction means 10c as described above, when trying to use a specific function when in the out-of-service area A2 or when the offline mode is set Since verification information input is required, the use of specific functions by third parties can be prevented. On the other hand, when the mobile phone 1 is in the coverage area A1, the input of collation information is not required, so the operability of the owner is hardly impaired. Also, if you are in the area A1, you can rest assured that the unavailable setting can be enabled by remote control means. Since it is also required to input verification information when canceling the offline mode, it is possible to prevent the act of using the specific function by canceling the offline mode only for a short time.

[0057] Although the invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. is there.
