Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a file protection method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
The mailbox account bound by the mobile terminal can be understood as an account of a mailbox which is set by a user and is associated with the mobile terminal; the monitoring of the mailbox account bound to the mobile terminal can be understood as that the mailbox associated with the mailbox account is monitored.
The preset instruction is sent through the mailbox account, so that the mobile terminal can be hidden, the application range is wider, even if the mobile terminal cannot be equipped with the SIM card or the SIM card is taken out, the preset instruction can be received through the network, the probability that the mobile terminal can receive the preset instruction is improved, and the probability that the file information lost by a user is retrieved is improved.
In addition, a background running program can be arranged on the mobile terminal to perform real-time monitoring. The relevant parameters of the program can be set on a setting interface of the mobile terminal, for example, a locking instruction, an uploading instruction, a destroying instruction and the like can be set on the setting interface; in addition, before setting the parameters of the program, the security password may be required to be input, specifically, the security password may be a fingerprint password input through a fingerprint identification module, or a security password composed of any number of digits. Therefore, monitoring is carried out through the background running program, and the user can conveniently carry out corresponding adjustment according to own habits.
And 102, identifying a target file stored by the mobile terminal if the mailbox account receives a preset instruction.
If the mailbox account receives a preset instruction, the judgment can be made as to whether the mailbox associated with the mailbox account receives the preset instruction.
The preset instruction can be understood as an instruction preset by a user and used for instructing the mobile terminal to lock, upload, destroy and the like the target file; specifically, the text information may be text information carrying some specific fields, for example, a text segment of "666 SD SC XH" preset by the user through the mobile terminal is a preset instruction, and as long as the mobile terminal receives the text segment of "666 SD SC XH" through a mailbox associated with the mailbox account, the target file stored by the mobile terminal may be identified. Of course, other character information, for example, "upload all files", "delete all files", etc., may be used, as long as the operation corresponding to the character information is set in advance.
In addition, the target file stored in the mobile terminal may be understood as a file stored in the mobile terminal and having a corresponding relationship with the preset instruction, and the files corresponding to the preset instruction are usually set in advance for the user, and the files may be files classified according to a certain logic rule; for example, if the preset instruction is set to "666 SD SC XHPHOTO", the mobile terminal recognizes all files classified as pictures on the mobile terminal after monitoring that the mailbox account receives "666 SD SC XH PHOTO".
And 103, locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file.
The target file is locked, which can be understood as that the mobile terminal locks the identified target file; the output inhibition can be understood as that the target file locked by the mobile terminal cannot be displayed or played; for example, if the identified target file is a sound recording file on the mobile terminal, the sound recording file is hidden, and the sound recording file is prohibited from being played; therefore, the illegal owner of the mobile terminal can be prevented from viewing files which the user wants to protect or retrieve when the mobile terminal uploads and backs up the target files, and the protection effect of the mobile terminal on the file information is higher.
In addition, the cloud server associated with the mobile terminal can be a cloud server which is preset by a user and is bound with the mobile terminal, and the mobile terminal can have authority to log in the bound cloud server. For example, the mobile terminal is provided with a cloud server including a network disk a and a cloud disk B, the network disk a is bound with the mobile terminal by a user, the network disk a is the cloud server associated with the mobile terminal, the mobile terminal is authorized to log in the network disk a at the moment, the cloud disk B is still in a normal use mode, and the mobile terminal does not have permission to log in the cloud disk B.
The reporting of the target file and the destruction of the target file can be understood as that the mobile terminal uploads the target file to the cloud server and executes the operation of deleting the target file when the target file is uploaded; so that the user can retrieve the desired file.
The target file may be all files stored by the mobile terminal, or may also be a part of files stored by the mobile terminal; the partial files can be marked or classified files stored in the mobile terminal, such as files marked as private files; or the partial file may also be a partial file specified by the preset instruction.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In this way, in the embodiment of the present invention, the mailbox account bound to the mobile terminal is monitored; if the mailbox account receives a preset instruction, identifying a target file stored by the mobile terminal; and locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file. The mobile terminal can upload the file information to the cloud server when the file information is lost and destroy the file information when the file information is uploaded, so that the leakage of the file information is avoided, and the protection effect on the file information is better.
Referring to fig. 2, fig. 2 is a flowchart of another file protection method according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that, if the mailbox account receives a preset instruction, the present embodiment identifies a pre-specified target file stored in the mobile terminal. As shown in fig. 2, the method comprises the following steps:
The related description of step 201 has been set forth in detail in the previous embodiment, and will not be repeated.
The pre-designated target file stored in the mobile terminal may be understood as a file pre-selected or designated by the mobile terminal when the mobile terminal is not lost, for example, a file marked by a user may be used, specifically, the user marks a text document with a certain secret as an important file, and simultaneously marks several private photos as the important file, so that after receiving a preset instruction, the mobile terminal locks, uploads and destroys all files marked as the important files in advance.
It should be noted that step 202 is optional, for example: step 202 may be replaced by identifying a target field included in a preset instruction and identifying a target file stored by the mobile terminal and corresponding to the target field if the mailbox account receives the preset instruction.
The target field may be a field corresponding to some specific files, which is set in advance for the mobile terminal. For example, if the preset instruction is "666 delete pictures", then "pictures" are the target fields, and the "pictures" field corresponds to all files classified as pictures on the mobile terminal.
Therefore, the file information on the mobile terminal can be protected more efficiently and more specifically.
And 203, locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file.
The related description of step 203 has been set forth in detail in the above embodiment, and will not be repeated.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In this way, in the embodiment of the present invention, the mailbox account bound to the mobile terminal is monitored; if the mailbox account receives a preset instruction, identifying a target file stored by the mobile terminal; and locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file. The mobile terminal can upload specific file information to the cloud server when the file information is lost, and destroy the file information after uploading is finished, so that leakage of the file information is avoided, and the file information is better protected.
Referring to fig. 3, fig. 3 is a flowchart of another file protection method according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that if the mailbox account receives a preset instruction, the target mailbox account that sends the preset instruction is identified; and judging whether the target mailbox account is a mailbox account predetermined by the mobile terminal. As shown in fig. 3, the method comprises the following steps:
and 301, monitoring the mailbox account bound by the mobile terminal.
The related description of step 301 is already described in detail in the first embodiment, and will not be repeated here.
Since any mailbox account can send the preset instruction, there is a risk that an illegal owner of the mobile terminal maliciously sends the preset instruction through any mailbox account under the condition that the illegal owner knows the preset instruction, and therefore whether a target mailbox account sending the preset instruction is a mailbox account designated by a user needs to be identified.
And step 303, judging whether the target mailbox account is a mailbox account predetermined by the mobile terminal.
The predetermined mailbox account number of the mobile terminal may be an account number set by the user according to own habits or requirements, for example, the user has a plurality of mailbox account numbers, and the standby mailbox account number of the mailbox account numbers may be set as the predetermined mailbox account number of the mobile terminal. Step 303 can be said to correspond to verifying the identity of the sender of the preset instruction.
It should be noted that if the target mailbox account is not the predetermined mailbox account of the mobile terminal, the determination may be continued, or the process may be ended, and fig. 3 in the implementation of the present invention is exemplified by ending the process.
And 304, identifying a target file stored by the mobile terminal if the target mailbox account is a mailbox account predetermined by the mobile terminal.
Step 304 represents that only if the mailbox account sending the preset instruction is identified as the mailbox account predetermined by the mobile terminal, the subsequent operation will be executed.
For example, a mobile phone of B is stolen by a first, the first and the second send a mail carrying a preset instruction to a mailbox bound by a mobile phone of B through an a mailbox and a B mailbox respectively, and B designates the B mailbox as a mailbox capable of enabling the instruction to take effect before the first, so that the preset instruction sent by any mailbox except the B mailbox cannot take effect, that is, the preset instruction maliciously sent by the stealer through the a mailbox is invalid.
And 305, locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file.
The related description of step 305 has been set forth in detail in the first embodiment, and will not be repeated.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In this way, in the embodiment of the present invention, the mailbox account bound to the mobile terminal is monitored; if the mailbox account receives a preset instruction, identifying a target mailbox account which sends the preset instruction; judging whether the target mailbox account is a mailbox account predetermined by the mobile terminal; if the target mailbox account is a mailbox account predetermined by the mobile terminal, identifying a target file stored by the mobile terminal; and locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file. The mobile terminal can upload specific file information to the cloud server when the file information is lost, and destroy the file information after uploading is finished, so that leakage of the file information is avoided, and the file information is better protected; and only if the mailbox account number for sending the preset instruction is identified to be the predetermined mailbox account number of the mobile terminal, the subsequent operation can be executed, so that the protection of the file information can be further improved.
Referring to fig. 4, fig. 4 is a flowchart of another file protection method according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that if the mailbox account receives a preset instruction, the target mailbox account that sends the preset instruction is identified; and judging whether the target mailbox account is a mailbox account predetermined by the mobile terminal. As shown in fig. 4, the method comprises the following steps:
The related description of step 401 has already been set forth in detail in the first embodiment, and will not be repeated here.
The location information may be global positioning system location information of the mobile terminal.
And step 403, judging whether the position information is a resident position recorded by the mobile terminal.
The resident position can be understood as a position where the mobile terminal stays for a long time and appears frequently; such as home and business, etc.
It should be noted that if the location information is a resident location recorded by the mobile terminal, the determination may be continued or the process may be ended, and fig. 4 in the implementation of the present invention exemplifies that the process is ended.
Optionally, after the step of determining whether the location information is a resident location recorded by the mobile terminal, the method further includes:
if the position information is a resident position recorded by the mobile terminal, initiating a call request to a target terminal pre-bound by the mobile terminal, and if a call connection is established with the target terminal, sending voice including the position information to the target terminal; or,
and if the position information is the resident position recorded by the mobile terminal, sending a short message to a target terminal bound in advance by the mobile terminal, wherein the short message comprises the position information.
Since the mobile terminal is usually in a relatively secure environment, such as a home, a classroom, etc., when it is in a resident location, there is a possibility that the mobile terminal may be directly retrieved in a short time, and sometimes the owner cannot remember the location of the mobile terminal, when the mobile terminal is in such a relatively secure environment, the mobile terminal may be directly retrieved by sending location information to the owner, which is also the most direct and effective way to protect file information.
For example, the xiaoming forgets the mobile phone in a classroom where people often attend a class carelessly, finds that the mobile phone is invisible after class, and immediately sends a preset instruction to the mobile phone of the xiaoming, and the xiaoming mobile phone is in a resident position, so that the xiaoming mobile phone dials the mobile phone of the xiaoming roommate and sends voice with information of the position where the xiaoming mobile phone is located, and then the xiaoming mobile phone can directly retrieve the mobile phone according to the voice.
Therefore, the file information of the mobile terminal can be protected more intelligently, directly and effectively.
And step 404, if the position information is not the resident position recorded by the mobile terminal, identifying a target file stored by the mobile terminal.
Because the owner of the mobile terminal carelessly forgets the mobile terminal to a safe environment at a certain place instead of the situation of real loss or theft, when the mobile terminal is located at a resident position, the mobile terminal is very likely to be in a safe and temporary forgetting situation, and the situation can be directly found back; if the mobile terminal is not located at the resident position, the mobile terminal is likely to be stolen or lost, and in such a case, the file information is easily leaked, so that if the location information is not the resident position recorded by the mobile terminal, the subsequent operation is performed.
For example, one day before Xiaoming, people drink more at night, people throw the mobile phone at home disorderly, and when the mobile phone wakes up the next day, the Xiaoming finds that the mobile phone is invisible, actually, the mobile phone is not really lost, only the Xiaoming forgets temporarily, the Xiaoming beats a brain bag, thinks that the mobile phone is dropped at a sandy place in the home, and because the resident position is at home, the file information does not need to be protected under the condition. However, if a user drinks more in the evening before xiaoming, and forgets to leave the mobile phone in a strange bar, after the user goes home, the user who happens to be in a bar picks up the xiaoming mobile phone and is based on the fact that the user is owned, and the bar does not belong to a resident position, the risk of losing file information is high, and the file information needs to be protected.
And 405, locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file.
The related description of step 405 has already been set forth in detail in the first embodiment, and will not be repeated here.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In this way, in the embodiment of the present invention, the mailbox account bound to the mobile terminal is monitored; if the mailbox account receives a preset instruction, identifying the position information of the mobile terminal; judging whether the position information is a resident position recorded by the mobile terminal; if the position information is not the resident position recorded by the mobile terminal, identifying a target file stored by the mobile terminal; and locking the target file to prohibit output, reporting the target file to a cloud server associated with the mobile terminal, and destroying the target file. The mobile terminal can upload specific file information to the cloud server when the file information is lost, and destroy the file information after uploading is finished, so that leakage of the file information is avoided, and the file information is better protected; moreover, file information on the mobile terminal can be protected more flexibly and intelligently.
