CONSTITUTION: When a user wants to open personal information, the user inputs a password(S1). If the inputted password is the same as a preset password, the user is able to continue to use a cellular phone or open the personal information(S2). If the inputted password is not the same as the preset password, a controller makes the user re-input the password. The controller counts the number of wrongly-inputted times(X)(S3). If the number of the wrongly-inputted times reaches a certain frequency(X), the controller cuts off battery power(S4).

Description

{Locking method for mobile phone}

The present invention relates to a mobile phone security method, in particular, in case of lost mobile phone, in order to restrict the leakage of personal information and the use of the mobile phone by inputting the password several times, if the wrong number of times is input, the battery power is cut off again and again The present invention relates to a method of securing a mobile phone, which is not driven by a power source and driven only by an external input power data communication cable.

Nowadays, due to the rapid development of wireless communication, mobile phones are rapidly spreading and various kinds are changing. In addition, mobile phones are almost indispensable, and their functionality has been extended to allow many people to store personal information in the phone's memory and output it from the phone whenever needed.

Because of the small size of mobile phones, the memory is limited, and in the early days, only the number of the phone number was stored. However, the size of hardware memory is getting smaller, and the amount of information that can be stored is dramatically increased. Therefore, users do not simply enter and use telephone numbers, but store complicated and information-rich personal information such as images, pictures, or sounds.

In addition, since the personal information is stored in the memory of the mobile phone, a security method of the mobile phone has been developed. However, in order to restrict the use of the mobile phone itself as well as the memory, the security method of the mobile phone has been developed. You can only use your memory or mobile phone if it matches your password. In general, the password is to enter a four-digit number has a lot of problems in security, the password may be entered a lot of numbers, in this case there is a problem that the user is difficult to memorize the password, usually as a password Four digits are used.

Similarly, the passbook or card password is a four-digit number, but in this case, if you enter the password incorrectly several times, there is a blocking function that prevents you from using it any more. Therefore, the mobile phone has been devised by the necessity of such a preventive measure.

The present invention has been made to solve the above-mentioned problems of the prior art, when a certain number of times of incorrect input when a password is entered for use or management of a mobile phone, the mobile phone is again driven by battery power while shutting off battery power. It protects the personal information stored in the mobile phone by protecting the personal information stored in the mobile phone by preventing it from being activated and enabling the mobile phone to be driven only by a data communication cable, which is an external input power. The purpose is to provide a mobile phone security method that can manage the use. In fact, the data communication cable connected to the terminal is considered to be somewhat complementary because it is very different for each terminal model.

In addition, when the battery power is cut off, the mobile phone security method according to the present invention is characterized in that the mobile phone is not driven again by the battery power until the password is correctly input after the external power input.

In addition, the mobile phone security method according to the invention is characterized in that the mobile phone in the state that the battery is cut off is driven again by the input of external power.

In addition, the mobile phone security method according to the invention is characterized in that the external power input is made via a data communication cable.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a configuration of a general mobile phone. In general, a mobile phone is connected to a control unit 3 that controls the overall operation of the mobile phone, and is connected to the control unit 3, and various components and the control unit 3 in the vicinity thereof. The interface unit 5 for interfacing various data input / output between the &lt; RTI ID = 0.0 &gt;), &lt; / RTI &gt; a memory 2 in which data is stored, a duplexer 10 for communicating with a base station via an antenna 11, and a voice. An audio unit 12 through which a signal or the like is input / output, an input unit 7 for the user to dial or input information, and a display unit 6 for displaying the state of the mobile phone so that the user can visually identify it. .

Here, the memory 1 is a ROM (ROM) for storing a predetermined program for controlling the overall operation of the mobile phone, the data input and output when the overall operation of the mobile phone by the control unit 3 and various data processed RAM is configured to store the data for the password used in the present invention.

The duplexer 10 communicates with the base station through the antenna 11 so that a signal is transmitted from the transmitter 9 to the base station through the antenna 11, and the signal from the base station through the antenna 11 is received by the receiver ( 8), the receiving unit 8 controlled by the control unit 3 through the interface unit 5 receives a radio signal output from the duplexer 10, the transmitting unit 9 is the audio unit 12 Transmits the modulated radio signal from the duplexer 10.

The audio unit 12 is controlled by the control unit 3 via the interface unit 5, modulates a radio signal from a voice signal input through the microphone 13, and receives a radio signal received through the receiver 8 Is demodulated and sent to the speaker 14 as an audio signal. In addition, the audio unit 12 detects the ring signal through the receiver 8 when the ring signal is generated from the base station and transmits the ring signal through the ringer 15.

The input unit 7 includes numeric keys for dialing. When the user presses a predetermined key, the input unit 7 generates corresponding key data and outputs the corresponding key data to the interface unit 5.

The display unit 6 includes a liquid crystal display (LCD) for displaying a variety of information, is controlled by the control unit 3 through the interface unit 5, the data generated from the input unit 7 and the control unit 3 It receives and displays various information processing signals from it.

In addition, the power source of the mobile phone typically uses a rechargeable battery 3 so that it can be carried and carried, and a data communication cable 4 is installed for communication, data exchange with other devices, or input of an external power source.

The invention of the cellular phone security according to the present invention will be described with reference to the configuration of the cellular phone configured as described above with reference to FIG.

First, when a user usually sets a password in a mobile phone, for example, to limit the overall use of the mobile phone and to protect personal information, for example, reading personal information such as a telephone number of a customer, etc. stored in the memory 1. It can be divided into cases for limiting That is, when the user sets a password to restrict the overall use of the mobile phone, the user who wants to use the mobile phone must enter a password to use the mobile phone such as dialing. The function of can be used without inputting the password, but if you want to read the personal information, you must enter the password.

Since the security function for the password input is generally programmed so that the user can decide arbitrarily, the user who has troublesome password does not need to use the security function through the password input at all.

In addition, since such a security function is typically carried by the user himself or herself, it is rare to enter a password to limit the overall use of the mobile phone.

On the other hand, the password is different depending on the various mobile phones, but the situation is based on the four-digit number is usually set to the password. Therefore, it can be from 0000 to 9999. In this case, the probability of correcting the password is 1 in 10000, so the security function can be properly performed. In practical cases, however, people who have a relationship with the user of the mobile phone often know some special numbers related to the user (for example, a telephone number), and the user may use the special numbers for convenience of memory. In most cases, passwords are set so that personal information is leaked.

In particular, when a user other than the user enters a password into a mobile phone, a combination of various numbers related to the user is entered. If the entered number is different from the password, it is programmed so that the user can enter the password again. In many cases, you can find out your password by entering it again and again. On the other hand, when the user fails to enter the password, the user often presses a wrong key or enters a different password. In that case, the user inputs a matching password again to complete the password input in two or three times. In most cases.

The present invention is implemented on the basis of the above point, if the password input (S1) is a wrong number of times, the control unit 3 cuts off the power of the battery (S4), the external input power to the data communication cable Only by allowing the mobile phone to be driven again, the data communication cable differs depending on the mobile phone model, thereby preventing a large part of personal information leakage due to password leakage.

That is, as shown in FIG. 2, when a user wants to read personal information, a password is input (S1), and when the input number matches a password, continuous use of the mobile phone and personal information reading are possible. If the entered number is inconsistent with the password (S2), the password can be input again, but the control unit 3 counts the number X of incorrect inputs (S3). If the wrong number of times by which the password is input continuously continues to reach the predetermined number X, the controller 3 cuts off the battery 2 power (S4).

In this case, the control unit replaces the power of the battery 2 again and controls the power not to be input even when the mobile phone is driven by pressing the driving key of the input unit 7, and the power is supplied through the data communication cable 4 which is an external input power. The phone can only be driven when it is input.

The number of inputs X that cuts off the power of the battery 2 may be determined by the user or may be programmed in the memory 1.

As described above, in the mobile phone security method according to the present invention, even when the password is input several times, when the input number does not match the password, the mobile phone is powered again only by the external input power while shutting down the battery power. It provides the effect of further improving the information security function.

The present invention is not limited to the above embodiments and may be variously modified and implemented by those skilled in the art without departing from the technical gist of the present invention.
