For example, detection module 420 detects SIM card information every a time interval, and judges that whether the double SIM information detecting is identical.In double detection, if detection module 420 judgement current detection to the SIM information that detects of SIM information and last time identical, be left intact.If detection module 420 judgement current detection to SIM information not identical with the last SIM information detecting, judge and changed new SIM card.Detection module 420 adopts new digit corresponding to new SIM card to send information to preset number, so that terminal corresponding to default phone number is after receiving this information, send encrypted command information to new digit, this terminal recognition is gone out after encrypted command information, can be encrypted the file of appointment, thereby the All Files in the file of appointment is encrypted.
When being provided with at least one default identifying code for default phone number, detection module 420 judges that whether the identifying code of user's input is identical with default identifying code.Whether, when user's input validation code is when attempting to revise default phone number or changing SIM card, detection module 420 compares identifying code and the default identifying code of the user's input detecting, identical with default identifying code to judge the identifying code that user inputs.When the identifying code of detection module 420 judgement users input is identical with default identifying code, allow user to revise phone number, the phone number that user is inputted saves as default phone number.When the identifying code of detection module 420 judgement user inputs is not identical with default identifying code, do not preserve the phone number of user's input, default phone number is constant.
When the unlocking pin of the user's input receiving when detection module 420 judgement is identical with the default unlocking pin that is stored in inside, terminal is carried out to release, so that user checks the content in terminal.The unlocking pin of the user's input receiving when detection module 420 judgement be stored in inner default unlocking pin when different, do not remove the protection to terminal, be judged as release unsuccessfully, and the number of times of recording user release failure.If detection module 420 judgement users input the number of times of unlocking pin release failure continuously, reach preset value (for example, preset value is 5, but is not limited to this, can also be worth for other), triggering terminal sends encrypted command information automatically.When detection module 420 judgement receives number of times that user inputs unlocking pin and does not reach preset value, after this, if receive again the unlocking pin identical with default unlocking pin, terminal is carried out to release, the number of times having recorded is carried out to zero clearing processing simultaneously.
Receiving element 431 is for reception information.For example, receiving element 431 reception information, wherein, this information can be worked as and meets triggering terminal internal system when pre-conditioned and automatically generate and send, and also can be mounted in the information that phone number corresponding to SIM card on other-end sends.Receiving element 431 sends to recognition unit 432 by the information receiving.
Recognition unit 432 is for judging whether the information receiving is encrypted command information, wherein, if this information is the information automatically sending when number of times that described terminal judges user inputs unlocking pin release failure continuously reaches preset value, judge that this information is encrypted command information, or, if sending the phone number of this information is preset number, and this packets of information is containing encrypted instruction, judges that this information is encrypted command information.
Whether the information that for example, recognition unit 432 judgements receive is encrypted command information.
If the information that recognition unit 432 judgement receives is the information that terminal inner sends automatically, judge that whether this information be the information of transmission automatically when number of times that terminal judges user inputs unlocking pin release failure continuously reaches preset value.If recognition unit 432 these information of judgement are, the number of times of inputting continuously unlocking pin release failure as terminal judges user (for example reaches preset value, preset value is 5, but be not limited to this, can also be worth for other), the information that triggering terminal internal system sends automatically, recognition unit 432 is identified as encrypted command information by this information.
If the information that recognition unit 432 judgements receive is mounted in the information that phone number corresponding to SIM card on other-end sends, judge whether the phone number of transmission information is default phone number.If recognition unit 432 these phone numbers of judgement are default phone numbers, continue to judge whether this information comprises encrypted instruction; If recognition unit 432 these phone numbers of judgement are not default phone numbers, do not process this information.If it is default phone number that the phone number of information is sent in recognition unit 432 judgements, and this packets of information is containing encrypted instruction, recognition unit 432 is identified as encrypted command information by this information.
Be understandable that, in the present embodiment, encrypted command information is that, after terminal loss, terminal use, in order to prevent that the data of terminal from being leaked, initiatively sends to terminal by the phone number by default.In other embodiments, also other trigger conditions can be set, make when meeting default trigger condition, trigger default phone number and send encrypted command information to terminal.
Judge module 440 is for judging whether encrypted command information comprises password, and wherein, password is numeral and/or alphabetical combination.
For example, after judge module 440 judges that the information receiving is enciphered message, judge whether enciphered message comprises password, wherein, password is numeral or alphabetical, or numeral and alphabetical combination.In other embodiments, password can be also extended formatting, such as, character string, binary code etc.
Judge module 440 sends to control module 450 by judged result.
The judged result that control module 450 does not comprise password for receiving encrypted command information, when encrypted command information does not comprise password, control module 450 is used preset password to be encrypted the file of appointment, when encrypted command packets of information contains password, the password that control module 450 is used encrypted command packets of information to contain is encrypted the file of described appointment.
For example, when judgment result is that of receiving of control module 450 do not comprise password in encrypted command information, control module 450 is used preset password to be encrypted the file of appointment, thereby uses preset password to be encrypted files all in the file of appointment.When judgment result is that in encrypted command information of receiving of control module 450 comprises password, control module 450 is obtained the password in encrypted command information, and use the password getting to be encrypted the file of appointment, thereby use the password getting to be encrypted all files in the file of needs encryption.Wherein, wherein, while comprising encrypted instruction in the information that the default phone number of judge module 440 judgements sends, control module 450 is not reported to upper layer application,, does not present to user that is, makes user cannot obtain password, thereby prevents password leakage.After control module 450 gets the password in encrypted command information, can delete encrypted command information, to prevent that encrypted command information from being revealed.
Be understandable that, in the present embodiment, need the password in preset password and encrypted command information to be one, when encrypted command information does not comprise password, use preset password to be encrypted the file in the file of appointment and this document folder; When encrypted command packets of information contains password, use the password getting to be encrypted the file in the file of needs encryption and this document folder, wherein, at least one file of appointment is all used identical Crypted password to be encrypted.In other embodiments, when the file of appointment is during at least two, also can be the corresponding preset password of file of each appointment or one of them password in corresponding encrypted command information, or also can, the corresponding password of file of each appointment, the corresponding subcipher of each file in this document folder.
Be understandable that, the encrypted command information that terminal sends automatically, can comprise password, also can not comprise password.In the present embodiment, when this encrypted command packets of information contains password, use the password in encrypted command information to be encrypted the file of appointment, when this encrypted command information does not comprise enciphered message, use preset password to be encrypted the file of appointment.In other embodiments, also can be set to work as terminal judges encrypted command is, during encrypted command information that the number of times that receives the unlocking pin of user input sends while reaching preset value automatically, no matter whether encrypted command information comprises password, directly use preset password to be encrypted the file of appointment.
In other embodiments, in the time of can also being set to pre-conditioned when meeting (not being restricted pre-conditioned) herein, to terminal, send delete command, to delete the file of preserving important information; Or user can also send delete command to terminal by default phone number, preserves the file of important information with permanent delet, and then prevent important information leakage.
Such scheme, in the situation that terminal is opened safe release, by the file of specifying at least one to encrypt, triggering terminal is set and sends the pre-conditioned of encrypted command information, make when meeting when pre-conditioned, triggering terminal automatically sends encrypted command and is encrypted with the file to appointment.And, can a default phone number be set for terminal association, and the default phone number of triggering is set to the condition of terminal transmission encrypted command information, when meeting trigger condition, make default phone number send encrypted command to terminal and be encrypted with the file to appointment, thereby realize, terminal is carried out to remote encryption.In this way, can increase the difficulty that cracks file, improve the safe class of data, thereby guarantee data security, when user brings back terminal, can directly file and the file encrypted are just decrypted and can be checked.
In several execution modes of the application, the file and the file that adopt DEA (Data Encryption Standard, DES) to encrypt needs are encrypted, but are not limited to this, also can adopt other cryptographic algorithm to be encrypted.
In more than describing, in order to illustrate rather than in order limiting, to have proposed the detail such as particular system structure, interface, technology, to thoroughly understand the application.Yet, not it will be clear to one skilled in the art that in there is no other execution mode of these details and can realize the application yet.In other situation, omit the detailed description to well-known device, circuit and method, in order to avoid unnecessary details hinders the application's description.
