September 2, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- ZTE Corporation (Shenzhen, CN) has been issued patent number 8811949, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventor is Shen, Shaowu (Shenzhen, CN).

This patent was filed on June 11, 2010 and was published online on August 19, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Due to system complexity and application diversity, mobile terminals become like personal computers (PCs) when they are used. Users have become accustomed to storing their important personal information and files in mobile terminals because of portability. This is especially the case for business mobile terminals, which store large amounts of important user information. However, such portability also produces a high risk of losing mobile terminals. A large number of mobile terminal users have experienced such loss. Once a mobile terminal is lost, a user may suffer great economic loss. Therefore, if a mobile terminal is lost, a user would always want to ensure that personal information stored in the mobile terminal is well protected when recovering the lost mobile terminal. However, current mobile terminals obviously do not have this function.

"At present, anti-theft methods commonly used for mobile terminals are as follows:"

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "In view of the above mentioned, the main objective of the present disclosure is to provide an anti-theft mobile terminal and an anti-theft method for a mobile terminal, so that related information in a mobile terminal can be retrieved when the mobile terminal is stolen and the mobile terminal can be accurately positioned.

"In order to the above objective, the technical solution of the present disclosure is implemented as follows.

"An anti-theft mobile terminal includes a setting unit, an encryption module, a password verification module, a detection module, a power management module, an information return module, an information deleting module, and a positioning module; wherein

"the setting unit is configured to set an International Mobile Subscriber Identity (IMSI) for the mobile terminal;

"the encryption module is configured to set a screen-lock password and an information return verification password of the mobile terminal;

"the password verification module is configured to verify a screen-unlock password input by a user, and unlock a screen after successful verification;

"the detection module is configured to detect a battery or an SIM card of the mobile terminal, and trigger the power management module to manage a power supply when detecting that the SIM card has been pulled out, the battery has been pulled out, or the battery has run down longer than a preset duration;

"the power management module is configured to stop a power supply function of the battery of the mobile terminal and start a standby power supply to supply power to the information return module, the information deleting module, the positioning module, and the IMSI;

"the information return module is configured to receive an information return verification password from another mobile terminal, verify the information return verification password, and return information saved in a set storage area in the mobile terminal to the another terminal after successful verification;

"the information deleting module is configured to delete information having been returned by the information return module from the set storage area; and

"the positioning module is configured to position the mobile terminal, and periodically transmit positioning information to a network side or a specified mobile terminal.

"Preferably, the mobile terminal may further include:

"an SIM card binding module, configured to bind a set SIM card to the mobile terminal, and when the mobile terminal uses a non-set SIM card, refuse to provide a network access service to the non-set SIM card.

"Preferably, the SIM card binding module may be further configured to bind the IMSI of the mobile terminal to the set SIM card.

"Preferably, the password verification module may be configured to trigger the power management module to manage the power supply when the number of verification attempts exceeds a preset threshold, and is started after the mobile terminal is restarted or powered on again.

"Preferably, the power management module may not supply power to the information return module, the information deleting module, the positioning module, and the IMSI when the mobile terminal is powered by the battery normally.

"An anti-theft method for a mobile terminal includes: setting a screen-lock password and an information return verification password of a mobile terminal; and setting an IMSI for the mobile terminal; the method further includes: receiving and verifying a screen-unlock password input by a user, and unlocking a screen of the mobile terminal alter successful verification; when detecting that an SIM card of the mobile terminal has been pulled out, or a battery of the mobile terminal has been pulled out, or the battery has run down longer than a preset duration, stopping supply of power from the battery of the mobile terminal, starting a standby power supply, enabling the mobile terminal to enter an automatic running state, and using the IMSI of the mobile terminal as a communication identity;

"wherein the automatic running state comprises: receiving an information return verification password from another mobile terminal and verifying the information return verification password, returning information saved in a set storage area in the mobile terminal to the another terminal after successful verification, and deleting returned information from the set storage area; and starting an automatic positioning function of the mobile terminal and periodically transmitting current positioning information of the mobile terminal to a network side or a specified mobile terminal.

"Preferably, the method may further include:

"binding a set SIM card to the mobile terminal, and when the mobile terminal uses a non-set SIM card, refusing to provide a network access service to the non-set SIM card.

"Preferably, the method may further include:

"binding the IMSI of the mobile terminal to the set SIM card, and when the mobile terminal uses a non-set SIM card, refusing to provide a network access service to the non-set SIM card.

"Preferably, the method may further include:

"when an input verification password is incorrect to the mobile terminal and the number of verification attempts exceeds a preset threshold, stopping supply of power from the battery of the mobile terminal, and starting the standby power supply, and enabling the mobile terminal to enter the automatic running state; and automatically locking the screen of the mobile terminal when the mobile terminal is restarted or powered on again.

"Preferably, the method may further include:

"starting the standby power supply by the mobile terminal and enabling the mobile terminal itself to enter the automatic running state when the SIM card or the battery in the mobile terminal has been pulled out longer than the preset duration.

"In the present disclosure, by means of additional arrangement of the IMSI, the password encryption module, the positioning module and the standby power supply in a mobile terminal, when the mobile terminal is stolen or a screen-lock password has been input for many times, the mobile terminal stops its battery from supplying power, starts the standby power supply, and enters the automatic running state, i.e., an anti-theft state. In this case, the standby power supply only supplies power to a module related to the anti-theft state. In this way, the mobile terminal verifies a password requested to be input upon receiving a request for information return from a user who sends this request through another mobile terminal, and sends related information stored in a set storage area to the another mobile terminal after successful verification. Meanwhile, the positioning module of the stolen mobile terminal is started, automatically positions the mobile terminal, and sends positioning information to a network side or a specified mobile terminal. In this way, when a mobile terminal is lost, the lost mobile terminal can be accurately positioned, and can send related information stored in its set storage area to another terminal through which a request for information return is sent, after a user sends a password for information return through the another mobile terminal to the lost mobile terminal. The loss due to loss of a mobile terminal can be greatly reduced by means of the technical solution disclosed in the present disclosure."
