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.
It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the listed items that are shared.
The embodiment can be applied to terminals such as a smart phone and an ipad which are registered in a server, when the terminals such as the smart phone and the ipad are lost, a user can send an instruction to the terminals such as the smart phone and the ipad through the server, and after receiving the instruction, the terminals such as the smart phone and the ipad can send data stored in the terminals such as the smart phone and the ipad to the server for backup; meanwhile, the server can also send instructions to the terminals such as the smart phone and the ipad to format the terminals such as the smart phone and the ipad.
The embodiment of the invention discloses a data protection method and device, which can reduce the probability of data leakage. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flow chart of a data protection method according to an embodiment of the present invention. As shown in fig. 1, the data protection method may include the following steps.
S101, the server detects whether a data protection mode trigger event aiming at the registered terminal is received, if so, the steps S102 and S103 are executed, otherwise, the process is ended.
In the embodiment of the present invention, the server may refer to a computer device having performance such as computing capability, storage capability, and stability. Examples of the server include a non-86 server such as a mainframe, a mini-machine, and a UNIX server, and an x86 server. Alternatively, a personal computer with general performance may be used as the server.
The registered terminal may include a user equipment running an Android operating system, an iOS operating system, a Windows operating system, or other operating systems, such as a mobile phone, a mobile computer, an ipad tablet, a Personal Digital Assistant (PDA), etc., or a colloquially-called storage medium such as a mobile hard disk, a usb disk, etc.
The registered terminal may include a terminal registered in advance on the server, and the terminal registered on the server may be one or more. For example, when the registration terminal is a smart phone, the smart phone may input a phone serial number (IMEI) corresponding to the smart phone on a server registration interface shown in fig. 2A, and if the server verifies that the IMEI code is legal, the smart phone is successfully registered. It should be noted that the registered terminal in this embodiment and other embodiments of the present invention may be understood as a terminal that has been successfully registered with the server.
The data protection mode trigger event may include an identification number (e.g., a cell phone serial number, a user id, etc.) of the registered terminal and a data protection operation performed on the registered terminal. For example, a user (other terminal) may send the data protection mode trigger event on a data protection interface of the other terminal, and the user may send the data protection mode trigger event by clicking a registered terminal of the data protection interface and a data protection mode trigger key shown in fig. 2B, where clicking the registered terminal sends an id of the registered terminal, clicking the data protection mode trigger key sends a data protection operation executed by the registered terminal, and the like.
S102, the server sends a data protection mode starting instruction to the registered terminal, wherein the data protection mode starting instruction is used for instructing the registered terminal to send backup data and format the registered terminal.
When the server detects that the registered terminal is used through the identification number (e.g., a mobile phone serial number, a user id, etc.) of the registered terminal, step S102 may be executed. When the server detects that a terminal with the same id number as that of the registered terminal is accessing the internet in the network, step S102 may be executed. For example, when a terminal such as a smart phone or an ipad having the same id number as the id number of the registered terminal is accessing the internet, the server may execute step S102; or, when the server detects that the mobile hard disk and the usb disk with the same id number as the id number of the registered terminal are connected to a computer through a data line to read data, the server may execute step S102. Wherein, the network may include a mobile voice call network, a mobile data network, or a WIreless Fidelity (wifi) network; the data line may include an OTG line (english: On The Go), RS232, or RS485, etc.
The backup data according to the present invention may refer to a part of or all of data stored in a registered terminal such as a smart phone, an ipad, a mobile hard disk, or a usb disk. Formatting the registered terminal can restore the registered terminal to factory settings or completely delete all data in the registered terminal, etc. Where the data may refer to pictures, video, audio, or documents, etc.
The embodiment can be applied to the case that when a registered terminal such as a smart phone, an ipad, a mobile hard disk or a usb disk is lost, a user can start a registered terminal data protection mode on the data protection interface by using a registered terminal of the data protection interface and a data protection mode trigger key, when the server detects that the registered terminal is used (for example, when the mobile phone, the ipad is powered on to surf the internet, or the mobile hard disk or the usb disk is connected to a computer through a data line and other equipment is used for reading data), the server can send a data protection mode start instruction to the registered terminal, and after receiving the data protection mode start instruction, the registered terminal sends data such as an internally stored picture, video or audio to the server and restores factory settings.
S103, the server receives the backup data sent by the registered terminal and backs up the backup data.
Optionally, after step S103 is executed, the server detects whether the backup data is successfully backed up, if so, performs formatting on the registered terminal, and if not, may execute at least one backup data operation of step S102, and then perform formatting on the registered terminal, and the like.
Optionally, the server may further receive target backup data sent by the registered terminal, and backup the target backup data, where the target backup data is selected by the registered terminal from high to low according to the current network state and a preset data backup priority.
In this embodiment, the current network state may include a network unblocked state, a network blocked state, and the like, the registration terminal may store a plurality of data, each data in the plurality of data corresponds to one preset data backup priority, and if the current network state is the network unblocked state, the registration terminal may select a larger number of data as the target backup data in a sequence from high to low according to the preset data backup priorities; if the current network state is the network congestion state, the registration terminal may select less data as the target backup data according to the preset data backup priority from high to low.
For example, if the plurality of data are the picture 1, the picture 2, the picture 3, and the picture 4, the preset data backup priority corresponding to the picture 1 is 10, the preset data backup priority corresponding to the picture 2 is 20, the preset data backup priority corresponding to the picture 3 is 30, and the preset data backup priority corresponding to the picture 4 is 40, and if the current network state is the network smooth state, the registration terminal may select the picture 4, the picture 3, and the picture 2 as the target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low. If the current network state is the network congestion state, the registration terminal may select the picture 4 and the picture 3 as the target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low.
The higher the preset data backup priority is, the more important the data is, so that in the embodiment, when the network is relatively blocked, the important data can be preferentially selected for backup, and the serious loss caused by the failure of the important data backup due to the network blockage is avoided.
Optionally, after step S103 is executed, the server may further send a registered terminal locking instruction to the registered terminal, where the registered terminal locking instruction is used to enable the registered terminal to be in a locked state; or, the server may also send a geographic location request instruction to the registered terminal to trigger the registered terminal to send the current geographic location to the server, and the like.
By implementing the embodiment, under the condition that the registered terminal such as a smart phone is lost, a non-user can be prevented from using the registered terminal and the lost registered terminal can be positioned, so that the registered terminal can be conveniently found subsequently.
In the method described in fig. 1, the server may send a data protection mode on command to the registered terminal to backup the backup data sent by the registered terminal, and format the registered terminal. It can be seen that, by implementing the method described in fig. 1, when the registered terminals such as the smart phone and the ipad are lost, the server can back up the data stored in the registered terminals such as the smart phone and the ipad to avoid data loss, and can format the registered terminals such as the smart phone and the ipad to reduce the leakage probability of the data stored in the registered terminals such as the smart phone and the ipad.
Referring to fig. 2C, fig. 2C is a schematic flow chart of another data protection method according to an embodiment of the invention. As shown in fig. 2C, the data protection method may include the following steps.
S201, the registered terminal receives a data protection mode starting instruction which is sent by the server and aims at the registered terminal.
And S202, the registered terminal sends backup data to the server according to the data protection mode starting instruction.
The backup data according to the present invention may refer to a part of or all of data stored in a registered terminal such as a smart phone, an ipad, a mobile hard disk, or a usb disk. Where the data may refer to pictures, video, audio, or documents, etc.
And S203, the registered terminal formats the registered terminal according to the data protection mode starting instruction.
Formatting the registered terminal can restore the registered terminal to factory settings or completely delete all data in the registered terminal, etc.
Optionally, the registered terminal may further obtain a current network state, where the current network state includes clear or blocked; if the current network state is smooth, selecting first target backup data; if the current network state is blocking, selecting second target backup data; and sending the first target backup data or the second target backup data to the server.
Optionally, if the current network state is congestion, selecting corresponding second target backup data from high to low according to a preset data backup priority.
In this embodiment, the registration terminal may store a plurality of data, each of the plurality of data corresponds to one preset data backup priority, and if the current network state is the network unblocked state, the registration terminal may select more data as the first target backup data in an order from high to low according to the preset data backup priorities; if the current network state is the network congestion state, the registration terminal may select less data as the second target backup data according to the preset data backup priority from high to low.
For example, if the plurality of data are the picture 1, the picture 2, the picture 3, and the picture 4, the preset data backup priority corresponding to the picture 1 is 10, the preset data backup priority corresponding to the picture 2 is 20, the preset data backup priority corresponding to the picture 3 is 30, and the preset data backup priority corresponding to the picture 4 is 40, and if the current network state is the network smooth state, the registration terminal may select the picture 4, the picture 3, and the picture 2 as the first target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low. If the current network state is the network congestion state, the registration terminal may select the picture 4 and the picture 3 as the second target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low.
In the method described in fig. 2C, when a registration terminal such as a smartphone or an ipad is lost, the registration terminal may send data stored inside to the server for backup, and the registration terminal performs formatting at the same time, it can be seen that by implementing the method described in fig. 2C, when a registration terminal such as a smartphone or an ipad is lost, the leakage probability of the data stored in the registration terminal can be reduced.
Referring to fig. 3, fig. 3 is a schematic flow chart of a data protection system according to an embodiment of the present invention. As shown in fig. 3, the data protection system may include the following steps.
S301, the server detects whether a data protection mode trigger event for the registered terminal is received, if so, steps S301 to S306 are executed, otherwise, the process is ended.
The data protection mode trigger event may include an identification number (e.g., a mobile phone serial number, a user id, etc.) of the registered terminal and a data protection operation performed on the registered terminal; for example, the user may send the data protection mode trigger event by clicking a registered terminal of the data protection interface and a data protection mode trigger key shown in fig. 2B, where the user clicks an id of the registered terminal that is sent by the registered terminal, and clicks the data protection mode trigger key, i.e., sends a data protection operation executed by the registered terminal.
S302, the server sends a data protection mode opening instruction to the registered terminal, wherein the data protection mode opening instruction is used for instructing the registered terminal to send backup data and format the registered terminal.
In this embodiment, the definitions of the registered terminal and the server may refer to the description in fig. 1, and are not described herein again.
When the server detects that the registered terminal is used through the identification number (e.g., a mobile phone serial number, a user id, etc.) of the registered terminal, step S302 may be executed. When the server detects that a terminal with the same identification number as that of the registered terminal is in networking use, the server may execute step S302. For example, when a terminal such as a smart phone or an ipad with the same id number as the registered terminal is being used for networking, the server may execute step S302; or, when the server detects that the mobile hard disk and the usb disk with the same id number as the id number of the registered terminal are connected to a computer through a data line to read data, the server may execute step S302. Wherein, the network may include a mobile voice call network, a mobile data network, or a WIreless Fidelity (wifi) network; the data line may include an OTG line (english: On The Go), RS232, or RS485, etc.
S303, the registered terminal receives the data protection mode opening instruction for the registered terminal sent by the server.
And S304, the registered terminal sends backup data to the server according to the data protection mode starting instruction.
The backup data according to the present invention may refer to a part of or all of data stored in a registered terminal such as a smart phone, an ipad, a mobile hard disk, or a usb disk. Where the data may refer to pictures, video, audio, or documents, etc.
S305, the server receives the backup data sent by the registered terminal, and backs up the backup data.
S306, the registered terminal carries out formatting on the registered terminal according to the data protection mode starting instruction.
Formatting the registered terminal can restore the registered terminal to factory settings or completely delete all data in the registered terminal, etc.
Therefore, the system described by implementing fig. 3 can reduce the leakage probability of the data stored in the registration terminal when the registration terminal such as a smart phone, an ipad, etc. is lost.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a server according to an embodiment of the present invention. Wherein, the server shown in fig. 4 may include:
a receiving unit 402, configured to detect whether a data protection mode trigger event for a registered terminal is received.

The receiving unit 402 is further configured to receive the backup data sent by the registered terminal.
A processing unit 403, configured to backup the backup data received by the receiving unit 402.
Optionally, the receiving unit 402 is specifically configured to receive the target backup data sent by the registered terminal.
The processing unit 403 is specifically configured to backup the target backup data received by the receiving unit 402, where the target backup data is selected by the registered terminal according to a current network state and a preset data backup priority from high to low.
In this embodiment, the current network state may include a network unblocked state, a network blocked state, and the like, the registration terminal may store a plurality of data, each data in the plurality of data corresponds to one preset data backup priority, and if the current network state is the network unblocked state, the registration terminal may select a larger number of data as the target backup data in a sequence from high to low according to the preset data backup priorities; if the current network state is the network congestion state, the registration terminal may select less data as the target backup data according to the preset data backup priority from high to low.
For example, if the plurality of data are the picture 1, the picture 2, the picture 3, and the picture 4, the preset data backup priority corresponding to the picture 1 is 10, the preset data backup priority corresponding to the picture 2 is 20, the preset data backup priority corresponding to the picture 3 is 30, and the preset data backup priority corresponding to the picture 4 is 40, and if the current network state is the network smooth state, the registration terminal may select the picture 4, the picture 3, and the picture 2 as the target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low. If the current network state is the network congestion state, the registration terminal may select the picture 4 and the picture 3 as the target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low.
The sending unit 401 is further configured to send a registered terminal lock instruction to the registered terminal after the backup data is backed up, where the registered terminal lock instruction is used to enable the registered terminal to be in a locked state.

The sending unit 502, when executing the step of selecting the second target backup data if the current network state is congestion, is specifically configured to select the corresponding second target backup data from high to low according to the preset data backup priority if the current network state is congestion.
In this embodiment, the registration terminal may store a plurality of data, each of the plurality of data corresponds to one preset data backup priority, and if the current network state is the network unblocked state, the registration terminal may select more data as the first target backup data in an order from high to low according to the preset data backup priorities; if the current network state is the network congestion state, the registration terminal may select less data as the second target backup data according to the preset data backup priority from high to low.
For example, if the plurality of data are the picture 1, the picture 2, the picture 3, and the picture 4, the preset data backup priority corresponding to the picture 1 is 10, the preset data backup priority corresponding to the picture 2 is 20, the preset data backup priority corresponding to the picture 3 is 30, and the preset data backup priority corresponding to the picture 4 is 40, and if the current network state is the network smooth state, the registration terminal may select the picture 4, the picture 3, and the picture 2 as the first target backup data according to the preset data backup priorities corresponding to the plurality of data from high to low.
