TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile phone, and more particularly, to a mobile phone provided with a function of preventing misuse in the event of misplacement, theft, and the like, and protecting information stored therein.
[0002]
[Prior art]
2. Description of the Related Art In recent years, not only a telephone directory function for registering a telephone number of a destination but also various information such as a mail address and personal information of the destination can be registered in a portable telephone. In addition, portable telephones capable of inputting personal information such as the address and date of birth of the owner are increasing. The functions themselves are convenient, and the user usually uses them for various purposes.However, if the mobile phone that registered them is lost or stolen, the Even if the contract itself is cancelled, such personal information and the like remain on the mobile phone, and there is a risk of being misused by others who do not know this.
[0003]
As a countermeasure to prevent the misuse of the mobile phone by others when the mobile phone is lost or stolen, there is a dial lock function that prevents key operation without inputting a personal identification number. In addition, Patent Document 1 discloses that a lost telephone is called several times from another telephone, and the telephone is called a predetermined number of times within a predetermined time from the same telephone number or a telephone of the same model. A mobile phone has been disclosed in which the mobile phone is prohibited from making an outgoing call or being in a key lock state when it receives a password.
[0004]
[Patent Document 1]
JP-A-2001-86228 [0005]
[Problems to be solved by the invention]
The dial lock function using a password requires an unlocking operation by inputting a password every time a call or mail is transmitted and received, and therefore, even a mobile phone having the function is often not used. Even if this function is used, the password is often a number of about four digits, and the risk of being broken is high.
[0006]
On the other hand, in the technique of Patent Literature 1, once the calling is prohibited or the key is locked, a password set separately is input to release the key. This password input is performed when the lost mobile phone is happily returned to the user, so there is no need to use it by day-to-day memorization, so even if the password contains complex characters and symbols, You only have to record it and use it without worrying that it will be easily broken. However, according to this technique, even if the call is prohibited or the key is locked, display, illumination, and the like are performed, and it can be seen that the mobile phone is in the operating state. For this reason, there is a risk that internal data such as a telephone directory will be read using an external interface or the like.
[0007]
An object of the present invention is to provide an abuse prevention mode in which a lost mobile phone is made to look as if it is broken by operation from another phone or the like, and is used by a person who has acquired information stored in the lost mobile phone. Provide a mobile phone that does not use it.
[0008]
[Means for Solving the Problems]
The present invention is a mobile phone having an abuse prevention mode in which at least a display function of a display unit, a lighting function on an operation unit, a vibration function at the time of an incoming call, and a ringing function of a speaker are stopped,

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. FIG. 1 is a schematic block diagram showing a configuration example of a mobile phone according to the present invention. A control unit 101, a transmission unit 102, a reception unit 103, a storage unit 104, an operation unit 105, a vibration unit 106, a liquid crystal display unit 107, and a speaker 108 , A microphone 109, an antenna 110, and the like. Although the above configuration is not particularly different from the conventional mobile phone, the storage unit 104 includes a program for realizing conventional functions such as calling and transmission / reception control, input of a telephone directory, display control, and the like. A keyword setting program 1041 for setting a keyword used in the abuse prevention mode, which is a feature of the present invention; and setting the mobile phone to the abuse prevention mode by operation from another telephone or the like using the keyword set by this program. An abuse prevention mode setting program 1042 for shifting is installed, and a keyword area 1043 is provided. These programs are also executed by the control unit 101.
[0010]
FIG. 2 is a flowchart of the keyword setting program 1041. The keyword setting program 1041 selects “abuse prevention setting” in a menu displayed on the display unit 107 by operating a function key on the operation unit 105 of the mobile phone. Shall be called by When called, first, a display as shown in FIG. 4 is performed to request the user to input a personal identification number (step 201). This password may be one commonly used in mobile phones. When the input password matches the password registered in advance in the mobile phone (Yes in step 202), a display as shown in FIG. 5 is displayed to select whether to set / cancel the abuse prevention mode setting function. Is requested from the user (step 203). However, in FIG. 5, “1. Settings” is surrounded by a frame, indicating a selected state by reverse display. Here, when "SETTING" is selected, a display as shown in FIG. 6 is displayed to request the user to input a keyword when setting the abuse prevention mode, and this keyword is stored in the keyword area 1043 of the storage unit 304 (step 204). ). Then, the abuse prevention mode setting function is made effective, and the display as shown in FIG. 7 is performed, and the process is ended (step 205). When "cancel" is selected on the display screen of step 203 (FIG. 5), the abuse prevention mode setting function is turned off, a screen as shown in FIG. 8 is displayed, and the process ends (step 206). The keyword setting program 1041 may have a function of only inputting a keyword, and may not have a function of canceling the abuse prevention mode setting function. In this case, for example, if the keyword is set, the abuse prevention mode setting function is enabled (ON), but if the keyword is not set, the abuse prevention mode setting function may be disabled (OFF).
[0011]
FIG. 3 is a flowchart of the abuse prevention mode setting program 1042. This program is activated when an e-mail (e-mail or short mail) is transmitted from another mobile phone or a personal computer to the mobile phone when the mobile phone is lost or the like, and is received by the mobile phone. Upon activation, it is first checked whether the abuse prevention mode setting function is ON (step 301). If it is ON, then the keyword area 1043 is set in either the body or the title of the received mail. It is checked whether a keyword is included (step 302). When the keyword is found, the portable telephone is shifted to the abuse prevention mode (step 303). In the abuse prevention mode, at least all display / illumination of the display unit 107, illumination of the operation unit 105, vibration by the vibration unit 106, and sounding of the speaker are all stopped. As a result, if the mobile phone is in the abuse prevention mode, it is determined that the mobile phone that has acquired the mobile phone is out of order, and even if there is an intention, the abuse can be given up. Further, if the key lock and the stop of the call are included in the abuse prevention mode, the abuse can be more reliably prevented.
[0012]
Further, when the mobile phone has the GPS reception function, even if the abuse prevention mode is set, the control functions of the transmission unit 102 and the reception unit 103 and the control unit 101 thereof may be set to a normal operation state. If the location information obtained by GPS is transmitted when the abuse prevention mode setting program 1042 sets the abuse prevention mode, the location of the lost mobile phone can be known.
[0013]
When the lost mobile phone returns, it is necessary to cancel the setting of the abuse prevention mode. This method depends on the function alive when entering the abuse prevention mode. If the receiving function is alive when entering the abuse prevention mode, abuse by receiving an e-mail containing a keyword and a simple code prepared for cancellation as well as entering the abuse prevention mode by the abuse prevention mode setting program What is necessary is just to cancel the prevention mode. Alternatively, the setting and cancellation of the abuse prevention mode may be alternately performed each time a mail containing a keyword is received. In addition, if the display is not displayed but the key operation is an effective abuse prevention mode, the key may be released by a predetermined key input, for example, a key input of the keyword itself. The processing for releasing these can be realized by preparing a simple program.
[0014]
The transition to or release from the abuse prevention mode should only be performed when the item is lost or returned, or even if the keyword used is complex, make a note of it. Can be small enough.
[0015]
【The invention's effect】
According to the present invention, in the event that a mobile phone is lost or stolen, it is possible to receive a short mail or e-mail including a keyword registered in advance from a remote place, as if the mobile phone is broken. This makes it possible to prevent the registered personal information from being misused as if it had been done.
In addition, when the mobile phone that has been lost, stolen, or the like is luckily returned, the mobile phone can be easily returned to the normal mobile phone state by, for example, receiving a mail including the same keyword again.
