Referring to fig. 2, fig. 2 is a schematic diagram illustrating an implementation flow of a method for protecting data security according to an embodiment of the present invention, where the method is applicable to a mobile terminal, and the mobile terminal includes: the mobile electronic data processing device comprises an electronic data processing device which can be used in moving, such as a smart phone, a tablet personal computer and a notebook computer and can be charged through an external charging wire. As shown in fig. 2, the method mainly includes the following steps S301 to S304.
S301, entering a safe charging mode when an event triggering the entering of the safe charging mode is monitored.
Specifically, the user may trigger the mobile terminal to enter the safe charging mode by pressing a preset physical key, or by touching a setting menu and a key in a preset safe charging setting interface. The mobile terminal is provided with an event monitor, and various events occurring in the mobile terminal are monitored through the event monitor, such as: a physical key press event, a touch event occurring in an interactive interface, a focus event, a menu event, and the like. The event monitor transmits the monitored events to different controls or different event processing methods of the same control so as to process the events.
S302, in a safe charging mode, when a data acquisition request sent by an external device through a charging line is received, whether the security level of target data pointed by the data acquisition request is greater than a preset level is judged.
The external device may be, for example: desktop computer, panel computer, portable computer, smart mobile phone, mobile charging equipment (like the treasured that charges) etc. can carry out the all kinds of equipment that charge to mobile terminal.
The charging wire can be a data line with a charging function, such as a USB charging wire, and can be accessed into the mobile terminal through a USB or other data interface. The external device can perform data interaction with the mobile terminal through the charging wire while charging the mobile terminal.
The security level of the target data can be customized according to the operation of a user. In an actual application example, if the user is not self-defined, the security level of all data is the highest by default.
It can be understood that, in this embodiment, only whether the security level of the data requested by the external device through the charging line is greater than the preset level is determined, and whether the security level of the data requested by the external device through other methods such as the wireless network is greater than the preset level is not determined. Therefore, data interaction between the mobile terminal and the external equipment in a safe interaction mode can be prevented from being influenced.
If the security level of the target data is greater than the preset level, step S303 is executed: and encrypting the target data according to a preset encryption mode, sending the encrypted target data to external equipment, and outputting decryption information in a preset mode.
The encryption method may include, but is not limited to: encrypting the target data according to a preset password, setting the attribute of the target data to be hidden, modifying the format of the target data, calling a third party encryption program for encryption and the like. The preset output mode may include, but is not limited to: instant messages, short messages, emails, and the like. The specific output mode can be customized by a user. Decryption information may include, but is not limited to: encryption password, decryption password, description information of third party encryption program for encryption, and presentation information of encryption method.
If the security level of the target data is not greater than the preset level, step S304 is executed: and transmitting the target data to the external device. In this way, the data requested by the external device is processed differently, so that the data security protection is more targeted, and the flexibility of the security protection is improved.
In the embodiment of the invention, in a safe charging mode, when a data acquisition request sent by an external device through a charging wire is received, if the security level of target data pointed by the data acquisition request is greater than a preset level, the target data is encrypted according to a preset encryption mode and then sent to the external device, and decryption information is output in a preset mode.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating an implementation flow of a method for protecting data security according to another embodiment of the present invention, where the method is applicable to a mobile terminal, and the mobile terminal includes: the mobile electronic data processing device comprises an electronic data processing device which can be used in moving, such as a smart phone, a tablet personal computer and a notebook computer and can be charged through an external charging wire. As shown in fig. 3, the method mainly includes the following steps S401 to S410.
S401, when an event triggering the safe charging mode is monitored, the safe charging mode is entered.
The mobile terminal is provided with an event monitor, and various events occurring in the mobile terminal can be monitored through the event monitor. The event monitor transmits the monitored events to different controls or different event processing methods of the same control so as to process the events.
Optionally, the event triggering the secure charging mode is a pressing event of a preset physical key. Specifically, when the event monitor monitors that a preset physical key is pressed, the event monitor responds to the event and enters a safe charging mode. The preset physical keys can be the existing functional keys customized by a user, such as: a power-on key, a power-off key, a volume key, a photographing key and the like. To avoid functional conflicts, it is preferable to have non-on and off keys, such as volume + key. Alternatively, the preset physical key may be a physical key dedicated to entering the secure charging mode. The pressing operation may be, but is not limited to: long press, multiple presses, etc. And the method can be customized by a user.
Optionally, the event triggering the entering of the secure charging mode is a confirmation button touch event occurring based on the secure charging prompt information. Specifically, when an external charging wire insertion event is monitored through an event monitor, the safety charging prompt information is output. Then, when a confirmation button touch event occurring based on the output safety charging prompt information is monitored through the event listener, a safety charging mode is entered. Wherein the confirmation button touch event occurs based on the secure charging alert information, for example: a touch event generated by an operation of one or more fingers of the user contacting, leaving, moving, etc. on a confirmation button provided in the safe charging prompt information output window.
Optionally, if a confirmation button touch event based on the safe charging prompt information is not monitored over a preset time period, or a rejection button touch event based on the safe charging prompt information is monitored, the output of the safe charging prompt information is cancelled, and charging is performed according to a normal charging mode, that is, in the normal charging mode, the external device can perform data interaction with the main control chip. It is understood that the confirmation button in the present embodiment is a button having a confirmation meaning, such as a button with the words "yes", "Y", "ok", and the like. The reject button is a button having a reject meaning, such as a button with the words "no", "N", "off", and the like.
To further illustrate the method for protecting data security provided by the present embodiment, taking the mobile terminal shown in fig. 6 as an example, when a pressing event of the physical key 1 in fig. 6 is monitored, a secure charging mode is entered in response to the pressing event. Or, still taking the mobile terminal shown in fig. 6 as an example, when an external charging wire 2 insertion event is monitored, popping up the window 3, and outputting the safe charging prompt information in the window 3. Then, when a confirmation button 4 touch event in the window 3 is monitored, the secure charging mode is entered. Optionally, before entering the safe charging mode in response to the pressing event of the physical key 1, the safe charging prompt message may also be output, and when a confirmation button 4 touch event in the window 3 is monitored, the safe charging mode is entered.
Optionally, the event triggering the entering of the secure charging mode is a confirmation button touch event occurring on the basis of a preset secure charging setting interface, for example: a touch event generated by operations of contact, exit, movement, etc. on various setup menus and buttons provided by one or more fingers of the user at the interface for triggering entry into the secure charging mode. Specifically, a safety charging setting function module is preset in the mobile terminal, and when an event triggering safety charging setting is monitored, a preset safety charging setting interface is output through the safety charging setting function module. And then, when a confirmation button touch event which occurs on the basis of the output safety charging setting interface is monitored, entering the safety charging mode. Wherein events that trigger a safe charging setting, such as: a touch event of a shortcut icon of the secure charging setting function module, a pressing event of a secure charging setting shortcut physical key, and the like.
S402, in the safe charging mode, when a data acquisition request sent by an external device through a charging line is received, whether the security level of target data pointed by the data acquisition request is larger than a preset level or not is judged.
If the security level of the target data is not greater than the preset level, step S403 is executed: and transmitting the target data to the external device.
If the security level of the target data is greater than the preset level, step S404 is executed: and generating a random password, and encrypting the target data according to the random password.
The external device may be, for example: desktop computer, panel computer, portable computer, smart mobile phone, mobile charging equipment (like the treasured that charges) etc. can carry out the all kinds of equipment that charge to mobile terminal.
The charging wire can be a data line with a charging function, such as a USB charging wire, and can be accessed into the mobile terminal through a USB or other data interface. The external device can perform data interaction with the mobile terminal through the charging wire while charging the mobile terminal.
The security level of the target data can be customized according to the operation of a user. In an actual application example, if the user is not self-defined, the security level of all data is the highest by default.
Specifically, the user may quickly trigger to enter the secure charging mode through any one of the manners in step S401, and in the secure charging mode, on one hand, the current input by the external device through the charging line is used to charge the loaded battery, and on the other hand, when a data acquisition request sent by the external device through the charging line is received, it is determined whether the security level of the target data pointed by the data acquisition request is greater than a preset level. And when the security level of the target data is greater than the preset level, generating a random password before sending, and encrypting the target data according to the random password. And when the security level of the target data is not more than the preset level, directly transmitting the target data to the external equipment.
Optionally, in other embodiments, the encryption password as the decryption information may also be customized by the user.
S405, judging whether a wireless network is connected currently.
If the wireless network is currently connected, step S406 is executed: and sending the random password as decryption information to a preset account in an instant message mode.
If no wireless network is currently connected, step S407 is executed: and outputting the random password as decryption information in a short message mode.
Through the judgment of the network type, the decryption information is output in the most appropriate mode, and the decryption information can be ensured to be really obtained by the actual owner of the computer. The account number of the receiver of the instant message and the mobile phone number for receiving the short message can be customized by the user. Optionally, the default is the local phone number of the mobile terminal and the user account associated with the instant messaging software logged in the mobile terminal. I.e. the user himself sends himself a short message or instant message containing decryption information.
S408, when the instant message or the short message is received, whether the received instant message or the short message contains the decryption information is judged.
Specifically, whether the received instant message or short message contains decryption information can be determined by extracting a keyword in the received instant message or short message and determining whether the keyword is matched with a preset keyword. The preset keyword may be, for example, "secure charging", "decryption", "password", or the like.
If the received instant message or short message does not contain the decryption information, step S409 is executed: and outputting the notification information of the received instant message or short message pushed by the system.
If the received instant message or short message contains decryption information, step S410 is executed: and intercepting the notification information of the received instant message or short message pushed by the system.
If the received instant message or short message does not contain the decryption information, it indicates that the received instant message or short message contains common information, and allows processing according to common logic, for example: and outputting the notification information of the received instant message or short message pushed by the system. If the received instant message or short message contains decryption information, the notification information of the received instant message or short message pushed by the system is intercepted, so that the situation that an actual owner who is not the local machine obtains key data of the local machine through mobile charging equipment such as a charging pal and the like and obtains the decryption information of the key data through peeping the push message of the local machine is prevented, and the data security of the local machine is further protected.
In another embodiment of the present invention, it may also be determined whether the received instant message or short message includes decryption information, instead of when the instant message or short message is received, when an event triggering the viewing of the instant message or short message is monitored, whether the instant message or short message to which the event points includes decryption information is determined, and if the instant message or short message to which the event points includes decryption information, an unlocking interface is output. And then, screen-off information is acquired through a screen-off interface, and if the screen-off information is matched with preset information, the content of the instant message or the short message pointed by the event is output. And if the instant message or the short message pointed by the event does not contain the decryption information, outputting the content of the instant message or the short message pointed by the event. Wherein, the screen-off information can be, but is not limited to, any one of fingerprint, character password, picture, gesture, and the like. In practical application, the screen unlocking information in the safe charging mode can be the same as or different from the screen unlocking information in the non-safe charging mode, and can be customized according to user operation.
Or, optionally, when the event triggering the viewing of the instant message or the short message is monitored while the steps S408 to S410 are executed, whether the instant message or the short message to which the event points includes the decryption information is determined, and if the instant message or the short message to which the event points includes the decryption information, a screen-unlocking interface is output. And then, screen-off information is acquired through a screen-off interface, and if the screen-off information is matched with preset information, the content of the instant message or the short message pointed by the event is output. And if the instant message or the short message pointed by the event does not contain the decryption information, outputting the content of the instant message or the short message pointed by the event.
Optionally, if the screen unlocking information is not matched with the preset information, the screen locking state is entered.
Optionally, when an external charging wire pull-out event is monitored, the secure charging mode is exited. Or exiting the safe charging mode and entering the normal charging mode according to the operation of exiting the safe charging performed by the user on a preset safe charging setting interface, or when detecting that the user presses a preset physical key to exit the safe charging mode. And resumes normal transmission of data when entering the normal charging mode.
In the embodiment of the invention, in a safe charging mode, when a data acquisition request sent by an external device through a charging wire is received, if the security level of target data pointed by the data acquisition request is greater than a preset level, the target data is encrypted according to a preset encryption mode and then sent to the external device, and decryption information is output in a preset mode.
