Description

  The present invention relates to a portable terminal that has taken measures against loss or theft, and in particular, can identify an abuser.

  2. Description of the Related Art In recent years, mobile phone terminals have become multifunctional, and are not limited to simple communication means, but are used as wallets for electronic payment by mounting IC cards, or are used as tickets, commuter passes, and the like. For this reason, there is a great deal of personal information held in mobile phone terminals, and in order to prevent third parties from peeping at this personal information, mobile phone terminals have password authentication means, and living things such as fingerprints, voice, and retina. Authentication means using scientific features are provided.

  In addition, when a mobile phone terminal is lost or stolen, it is possible to stop making and receiving the mobile phone by contacting the mobile phone operator. In addition, there is a mechanism for making a call to a lost mobile phone terminal from a telephone whose telephone number has been registered in advance and locking the operation of the mobile phone terminal. In addition, there is a service in which an operator of a system that receives a report from a user instructs the network to delete data recorded in the memory of the lost mobile phone terminal.

Various measures for recovering a mobile phone terminal lost due to theft or loss have been considered. For example, Patent Document 1 below describes that a lost mobile phone is called from another phone, a command is keyed in, and the mobile phone is set to “lost / theft countermeasure mode” by the DTMF signal. ing. A mobile phone in the “lost / theft protection mode” performs the following operation.
・ Sounds a warning sound different from the ringtone.
・ Display pre-recorded characters.
・ Continue to vibrate the mobile phone.
・ Calls the police automatically and communicates pre-recorded voice messages.
・ If a location confirmation function such as GPS is provided, the current location is reported by voice or text.

  Patent Document 2 below describes a mobile phone having a second incoming phone number in addition to a normal phone number. When the user loses the mobile phone, the user calls the second incoming phone number from another phone. When there is an incoming call to the second incoming telephone number, the mobile phone automatically turns on the power even when the power is off and shifts to the “lost / theft countermeasure mode”.

Patent Document 3 listed below describes a mobile phone that records a call made after shifting to the “lost / theft countermeasure mode” for a predetermined time. This call record becomes evidence for identifying the abuser when the mobile phone is collected. In addition, the mobile phone can automatically make a call to a predetermined phone to notify the call record.

  However, the conventional mobile phone terminal can leave the location information and call record of the mobile phone terminal or report it when theft or loss, but leave clear evidence that directly identifies the abuser. I can't. Therefore, even if the mobile phone terminal returns, it is difficult to identify the abuser.

  The present invention has been made in consideration of such circumstances, and an object thereof is to provide a portable terminal that can clearly identify an abuser at the time of theft or loss.

  In the present invention, at least one of a transmission unit that transmits a signal to a portable terminal, a reception unit that receives a signal, an authentication unit that uses a camera and biometric information, and a memory with an access control function that restricts access except for an operator Means and a control means for controlling the transition to the abuse prevention mode for restricting the use of the mobile terminal, the control means when the receiving means receives a command instructing the transition to the abuse prevention mode, or When the authentication process has failed a predetermined number of times, a transition to the abuse prevention mode is executed, and image data captured by the camera or biometric information acquired by the authentication unit is stored in the memory unit with an access control function.

  With this configuration, authentication data such as image data and fingerprints of a person who uses the mobile terminal during theft or loss is stored in the memory means with an access control function.

  In the portable terminal of the present invention, image data or biometric information stored in the memory means with access control function is automatically transmitted from the transmission means to a destination registered in advance.

  With this configuration, the status of the mobile terminal can be confirmed early.

  In the portable terminal of the present invention, the automatic transmission destination is limited to that permitted by the operator.

  With this configuration, it is possible to provide a security service by transmitting image data or biometric information of an abuser to the police or security service company permitted by the operator.

The portable terminal of the present invention can store biometric information such as image data and fingerprints of a person who has attempted to abuse the portable terminal during the period of theft or loss. It is possible to identify the information, and this information can be used to prove the abuser.
Such a function of the mobile terminal reduces the willingness to abuse the mobile terminal, and as a result, produces an effect of suppressing the abuse of the mobile terminal.

  FIG. 1 is a functional block diagram of a mobile terminal according to an embodiment of the present invention. The portable terminal includes an antenna 101, a control unit 102 for controlling the portable terminal, a receiving unit 103, a transmitting unit 104, an operation unit 105 such as keys and various buttons, a voice input unit 106, and a display unit 107. , Voice output means 108, camera 109, biometric authentication function 113 such as fingerprint sensor, voice recognition, and retina authentication, authentication input means 110 for inputting authentication data from biometric authentication function 113, memory means 111, and access control And an access control function-equipped memory means 112.

  The receiving unit 103 receives a signal from the radio base station via the antenna 101, and the transmitting unit 104 transmits a signal from the mobile terminal to the radio base station via the antenna 101. The voice input unit 106 inputs a voice, and the voice output unit 108 outputs a voice, a warning sound, and the like. The display means 107 displays various information to the user.

  The biometric authentication function 113 includes a fingerprint sensor that reads a fingerprint, a voice recognition unit that extracts voice features, a retina authentication unit that reads a retina pattern, and the like.

  The authentication input unit 110 captures biometric authentication data from the biometric authentication function 113 such as a fingerprint sensor, a voice recognition unit, or a retina authentication unit.

  The camera 109 is installed in a direction in which at least the face of the user who uses the biometric authentication function 113 and the user who operates the operation unit 105 can be photographed.

  The memory unit 111 stores a program and an application for controlling the mobile terminal. The control unit 102 controls the portable terminal according to a program stored in the memory unit 111.

  The memory means 112 with access control function stores data from the camera 109 and the authentication input means 110. This memory means 112 with an access control function can be accessed only by an operator, and access by the user is restricted. Further, the operator inputs the mail address of the destination to which the data stored in the memory means 112 with access control function is sent, or the address of the police or security service company reporting the data, etc., with the memory means 112 with access control function. Can be registered.

  This portable terminal is provided with a password authentication function and a biometric authentication function using fingerprint, voice, retina, or the like, and the user can select an authentication function to be effective from these authentication functions. When the password authentication function is enabled, the control unit 102 displays a display for prompting the input of the password on the display unit 107, and only when the password input from the operation unit 105 matches the password registered in advance. , Enable operation of mobile devices. When the biometric authentication function is enabled, the control unit 102 displays a display for prompting input of biometric authentication data on the display unit 107, and authentication data (biometric information) input from the authentication input unit 110. The mobile terminal can be operated only when 認証 matches the pre-registered authentication data.

  Further, the control unit 102 shifts the portable terminal to the abuse prevention mode when the authentication process using the effective authentication function fails for a predetermined number of times. In the abuse prevention mode, the camera 109 is activated to copy the face of the current operator of the portable terminal, and the image data is stored in the memory means 112 with an access control function. In addition, the biometric authentication data read by the biometric authentication function 113 is stored in the memory means 112 with an access control function.

  At this time, in order to take the operator's face with the camera 109, the mode immediately shifts to the abuse prevention mode when the authentication has failed a predetermined number of times, and the operator's face immediately after the authentication operation still faces the mobile terminal. It is desirable to shoot at the timing.

  Alternatively, for example, a display prompting the reuse of the fingerprint sensor is displayed on the display means 107, and the camera 109 is photographed at the timing when the operator places a finger on the fingerprint sensor, and at the same time, fingerprint data is acquired by the fingerprint sensor. A procedure is also conceivable.

  Further, the control means 102, when the password authentication function and the biometric authentication function are not enabled, when the DTMF signal based on the received signal received by the receiving means 103 indicates an instruction to shift to the abuse prevention mode, or When the received mail indicates an instruction to shift to the abuse prevention mode, the portable terminal is shifted to the abuse prevention mode.

  In addition, the control unit 102 automatically transmits the image data and biometric authentication data stored in the memory unit 112 with an access control function to a pre-registered address (designated mail address, police, security service company, etc.).

  The flowchart of FIG. 2 shows an operation procedure performed under the control of the control means 102 when the portable terminal is stolen or lost.

  Assume that the user loses his / her mobile terminal and another person picks up the mobile terminal (S10). In this case, when the user makes a call from another telephone and gives an instruction to shift to the abuse prevention mode, or when the operator of the current portable terminal has failed to authenticate the effective authentication function a predetermined number of times ( S11), the control means 102 locks the portable terminal so that it cannot be used, and executes the shift to the abuse prevention mode (S12).

  First, it is determined whether a camera is attached. If the camera is provided (S13—Yes), the camera is activated (S14). An image is automatically captured at a preset timing (S15), and the captured image data is stored in the memory means 112 with an access control function (S16). If the camera is not provided (S13-No), the process proceeds to step S17.

  Next, it is determined whether the authentication input unit 110 is provided. If the authentication input unit 110 is provided (S17-Yes), the presence / absence of authentication data is subsequently determined. (S18-Yes), the authentication data is fetched (S19), and the fetched authentication data is stored in the memory 112 with an access control function (S20).

  For example, in the case of a fingerprint sensor, every time fingerprint data is input from the fingerprint sensor, authentication data that is fingerprint data is captured. In the case of voice recognition, authentication data, which is voice data, is captured every time voice data for authentication is input. In the case of retina authentication, authentication data that is retina data for authentication is fetched. The acquired authentication data is stored in the memory 112 with an access control function as in the case of the camera. The storage method in the memory 112 with the access control function is sequentially stored in a specific area. However, when the area is full, it is easy to overwrite the oldest data sequentially.

  Next, it is determined whether automatic transmission of data is set. If automatic transmission is set (S21-Yes), the data stored in the memory means 112 with an access control function is transmitted to a pre-registered address. Then, the operation is finished (S24).

  Further, when the authentication input means is not provided (S17-No), the presence or absence of authentication data is determined, and when the authentication data is not input (S18-No), the image data stored in step S16 is stored. (S22), and if there is image data, the process proceeds to step S21 (S22-Yes).

  When there is no image data (S22-No) and when automatic transmission is not set (S21-No), the operation is terminated without passing through the step of S23 (S24).

  This automatic transmission may be performed at the timing when the image data or the authentication data is stored in the memory means 112 with access control function, or may be performed at an arbitrary timing by the user's remote control.

  In this portable terminal, when it is returned after being stolen or lost, it can be confirmed by reading the data in the memory 112 with an access control function whether or not it is misused.

  If the data stored in the memory 112 with the access control function is image data, an abuser can be easily identified from the image, and the abuser can be detected. Further, in the case of authentication data, it is possible to identify an abuser by collating it with data from the police or the like and to be cleared. Even if there is no matching data that matches, the authentication data becomes a criminal database, which can be effective information for increasing the future abuse rate of abusers.

  In addition, by automatically transmitting image data or authentication data stored in the memory means 112 with access control function, it becomes possible to check the status of the mobile terminal at an early stage.

  Further, in this portable terminal, it is possible to provide security services by limiting access to the memory means 112 with access control function to an operator or a police or a security service company permitted by the operator.

  In this way, this mobile terminal can clearly identify the abuser at the time of theft or loss, can recover the lost mobile terminal at a high rate, or based on clear evidence of the abuser Can be cleared. Such functions of the mobile terminal can reduce the willingness to abuse and deter abuse.

  Here, a portable terminal having both a camera and a biometric authentication function has been described. However, even a device having either a camera or a biometric authentication function can obtain data for identifying an abuser at the time of theft or loss. It is.

  INDUSTRIAL APPLICABILITY The present invention can prevent misuse of a portable terminal at the time of theft or loss, and has the utility of being able to store image data and authentication data that can identify an abuser, such as a mobile phone. It can be widely used for mobile terminals.
