Description

  The present invention relates to a portable terminal device and a security system having a wireless communication function, and more particularly to a security improvement technique for a portable terminal device.

  The mobile communication field represented by mobile phones has advanced rapidly in recent years and has come to be used in various places and situations. Along with that, the situation of dropping or forgetting the mobile phone is also increasing, but in this case, if there is no means to restrict the use of others, the owner himself will bear the call fee due to the use of others. Become. In addition, since a mobile phone stores a telephone directory and a call record, a problem such as infringement of privacy and illegal acquisition of trade secrets occurs when such information is seen by others.

A method of using a password has become widespread as a method of suppressing the use of a mobile phone by others. A mobile phone having a function of executing such a method has a function of invalidating key operations other than a predetermined operation so that key operations are not mistakenly performed. In order to prevent others from operating the mobile phone, it is necessary to enter a password when returning from a state in which the key operation is disabled. If the password does not match the pre-registered password, the key must be entered. It has a function that makes it impossible to recover from a disabled state.
There is also a technology that enables security protection of the terminal device by keyboard operation, and allows the operator to select whether to perform security protection at the time of starting the terminal device by operating the operator when the power of the terminal device is turned off. It has been proposed (for example, Patent Document 1).
The above-described method using a password is an effective means, but it requires time and effort for an operator to move to a state in which key operations are invalidated. Once the operation is disabled, the password must be entered if the person wants to perform any operation, so an extra operation such as an emergency call is required and the operation can be performed immediately. Can not. Therefore, it is a balance between security and operability, and when the operability is emphasized, a reduction in security must be tolerated.
In recent years, the trend has shifted from a straight-type mobile phone with a key exposed to a so-called folding mobile phone. Folding mobile phones do not have to worry about accidental key operations because the keys are not exposed, so it is not necessary to set key operations to be disabled, and a password protection function is used accordingly. The number of cases to do decreased. For this reason, there is a tendency that the risk of being used by others when the mobile phone is dropped or misplaced is increased.

Next, processing of the portable terminal device according to the present invention will be described using the flowchart shown in FIG.

First, the control means 2 determines whether or not a predetermined key input has been made via the input means 4 (S201). This key input information is registered in advance in the portable terminal device 1. The control means 2 determines whether or not the same key input as the registered key input information has been performed. When the portable terminal device 1 is a mobile phone, the control means 2 may determine whether or not a specific key input has been made only when it is in a standby state. Further, when the portable terminal device 1 is an electronic device other than a mobile phone, the control means 2 may determine whether or not a specific key input has been made only when the power is off. As for key input, the portable terminal device 1 may read information input to a keyboard used in other operations such as input of a telephone number. A dedicated key or switch may be provided, and information input using the key or switch may be read.
When the control unit 2 determines that the key input has been made, the wireless communication unit 6 reads the ID of the wireless communication device 8 stored in the storage unit 3 (S202). The ID of the wireless communication device 8 is registered in advance and stored in the storage unit 3.

  Next, the control unit 2 scans the wireless communication device 8 that can communicate with the wireless communication unit 6 (S203). Specifically, a scan signal is transmitted from the portable terminal device 1 and a response signal from the wireless communication device 8 for the scan signal is received. The response signal includes the ID of the wireless communication device 8. In the Bluetooth wireless communication system, this scan process corresponds to an inquiry process or a call process. As a result, when the control unit 2 finds the wireless communication device 8 (S204), the control unit 2 acquires the IDs of all the detected wireless communication devices 8 (S205). If not found, this process is terminated.

When there is an ID that matches the ID of the wireless communication device 8 stored in the storage unit 3 among the detected IDs of the wireless communication device 8 (S206), the control unit 2 enables the input unit and the output unit.
