Hold the operating position for the operation that clears data.For supporting the terminal of space-by-space operation, operating position can be offset terminal one
The position of set a distance.
The embodiment of the present invention can generate terminal data clearance order after receiving user and determining the information for selling terminal,
User data is removed with controlling terminal, it is ensured that improves the safety of user data.
Referring to figure 2., be the embodiment of the present invention data clearing method second procedure schematic diagram.Specifically, data are clear
Except method includes:
Step 201, it receives user and determines the information for selling terminal.This step hereinbefore describes in detail, therefore herein
It does not repeat.
Step 202, the information for selling terminal is determined based on user, generates data dump instruction.Step is hereinbefore made
It is discussed in detail, and therefore not to repeat here.
Step 203, data dump instruction is sent to terminal, user data is removed with controlling terminal.End in this step
End refers to that user determines the terminal sold.There are many embodiments of step 203.
The first embodiment, step 203 include: that data dump instruction is sent to terminal, are removed and are used with controlling terminal
The encryption key of user data.Wherein, encryption key is a kind of transformation rule information that user data is converted to ciphertext by plaintext.It adopts
User data can be quickly removed with present embodiment.
Second of embodiment, step 203 include: that data dump instruction is sent to terminal, are being detected with controlling terminal
When not being encrypted to user data, controlling terminal encrypts user data, and controlling terminal generates the encryption of user data
Key and controlling terminal remove the encryption key.Specifically, controlling terminal removes the encryption key, comprising: controlling terminal obtains

The corresponding operation of interface element of row " factory reset ", to open factory reset interface.For different types of end
End, the operating process information that controlling terminal is switched to data dump interface is different, does not enumerate herein.
The embodiment of the present invention can generate terminal data clearance order after receiving user and determining the information for selling terminal,
And data dump instruction is sent to terminal, it is instructed with controlling terminal based on data dump, removes user data automatically, can be improved
The safety of user data.
Referring to figure 3., be the embodiment of the present invention data clearing method third flow diagram.In the present embodiment, number
It is used for terminal reclaimer according to sweep-out method, terminal reclaimer to be the equipment for being traded and being recycled to terminal.Terminal
Reclaimer includes the operating device for touch control operation.Specifically, data clearing method includes:
Step 301, it receives user and determines the information for selling terminal.This step hereinbefore describes in detail, therefore herein
It does not repeat.
Step 302, the information for selling terminal is determined based on user, generates data dump instruction.Step is hereinbefore made
It is discussed in detail, and therefore not to repeat here.
Step 303, it is instructed according to data dump, terminal screen is shot, obtain shooting image.Shooting figure seems pair
What terminal screen was shot obtains original shooting image.Shooting image includes the image of terminal screen.Specifically, terminal recycles
Equipment includes the camera for being shot to terminal.Step 203 is specifically, terminal reclaimer is referred to based on data dump
It enables, control camera shoots terminal display interface, obtains shooting image.
Step 304, parsing shooting image, determines the operating position that user data is removed for controlling terminal.
As an implementation, terminal screen includes the operation element that user data is removed for triggering terminal.Wherein
Operating element can be the Touch control key on terminal screen, or the interface for being used to remove user data that terminal screen is shown
Element.Interface element can be icon, widget or the function choosing-item column etc. shown on end-user interface.
Specifically, step 304 includes: parsing shooting image, to determine the position of operation element；Position based on operation element
It sets, determines the operating position of operating device.Wherein, operating position can be the position of operation element, be also possible to opposite operate
The position of the positional shift certain distance of element.Wherein, parsing shooting image, with determine operation element position the step of, packet
Include: analysis shooting image identifies the operation element for removing user data；Determine the position of operation element.Further, divide
The step of analysis shoots image, identifies the operation element for removing user data, comprising: obtain the feature letter of the operation element
Breath；The region that inquiry matches with this feature information in shooting image, is determined as the operation element for the region.Specifically,
Characteristic information includes color characteristic information, texture feature information, spatial relation characteristics information and/or shape feature information.
It is worth noting that, in order to make terminal screen show the interface element for removing user data, terminal recycling is set
Standby that interface element idsplay order can be sent to terminal, interface element idsplay order is shown for controlling terminal for removing user
The interface element of data.
As another embodiment, can be by touch control operation that is specific, not needing trigger action element, control is eventually
User data is removed at end, which can be specific space-by-space operation.Step 304 can parse shooting image, to analyze use
In the position for the touch control operation for removing user data, and the position that this is analyzed is determined as the operating position of operating device.Tool
Body, for Proximity operation, operating position can be any position in the range of terminal screen, or can also be with
For position of the space-by-space operation sensing device as where front camera of terminal.Therefore, it can parse shooting image, to identify end
The position for holding screen or space-by-space operation sensing device determines operation according to the position of terminal screen or space-by-space operation sensing device
