Next, the screen locking password is set by the terminal as an example.
Fig. 3 is a flowchart of a method for obtaining occupancy information of a memory space according to an embodiment of the present application, which is executed by a terminal, and referring to fig. 3, the method includes:
step 301: and the terminal acquires the Recovery data packet.
The Recovery data packet comprises operation data of a Recovery mode and authority function data of an authority access control. The operation data is used for operating a Recovery mode, the authority functional data is used for operating an authority access control, the Recovery mode is used for providing an operation environment for the authority access control, and the authority access control has the authority for accessing the data in the memory space of the terminal.
The terminal may obtain the Recovery data packet through any of the following implementations.
In a first implementation manner, the terminal acquires the Recovery data packet through other terminals.
For convenience of distinction, this terminal will be referred to herein as a first terminal, and the other terminals will be referred to as second terminals. The first terminal and the second terminal may be connected through a wired network.
And the first terminal sends an acquisition request to the second terminal when detecting the preset operation, wherein the acquisition request is used for requesting acquisition of the Recovery data packet. And the second terminal sends a Recovery data packet to the first terminal based on the acquisition request, and the first terminal receives the Recovery data packet sent by the second terminal.
In a second implementation, the terminal obtains the Recovery packet from a System (System) partition of the terminal.
The System partition comprises a Recovery partition, a Recovery data packet is stored in the Recovery partition, and when a preset operation is detected, the terminal calls the Recovery data packet from the Recovery partition.
The preset operation can be set and changed according to the need, for example, the preset operation is the operation corresponding to the case that the key duration of the power key and the volume up key exceeds the preset duration when the terminal is in the power-off state.
Step 302: the terminal controls the terminal to enter a Recovery mode based on the operation data in the Recovery data packet.
The terminal acquires operation data from the Recovery data packet, and enters a Recovery mode by loading the operation data.
The Recovery mode is a mode for modifying data in the terminal and the terminal system, and in the mode, operations such as upgrading, system backup, factory setting Recovery and the like can be performed on the terminal system. In the embodiment of the application, in the Recovery mode, the terminal can also enable the permission access control, and the encrypted data in the memory space is decrypted through the permission access control.
Step 303: the terminal displays a statistical interface based on the first interface data in the Recovery data packet.
The Recovery data packet also includes first interface data.
In one possible implementation manner, the terminal directly obtains the first interface data from the Recovery data packet, and displays the statistical interface by loading the first interface data.
In another possible implementation, the terminal first obtains an enabling flag, and determines whether to display the statistical interface through the enabling flag. Accordingly, the process may be achieved by the following steps (1) to (2), including:
(1) And the terminal acquires an enabling mark corresponding to the permission access control.
The enablement flag is used to indicate whether the rights access control is enabled based on the statistical interface. The enabling flag setting process may be: and displaying a mark input interface when the terminal is in a starting-up state, wherein the mark input interface is used for inputting a mark password, acquiring the input mark password based on the mark input interface, and acquiring an enabling mark matched with the mark password.
In this implementation manner, the tag input interface may be a dial interface of the terminal, where the terminal obtains an input tag password, and the terminal determines a matched enabling tag according to the input tag password. The mark secret code is an engineering mode secret code and consists of characters and numbers, and different mark secret codes correspond to different enabling marks.
In the embodiment of the present application, referring to fig. 4, after the terminal obtains the enable flag in the power-on state, the enable flag may be written into a target partition, where the target partition may be a partition in the terminal other than a memory space, for example, the target partition is a cache (cache) partition, or other partitions, which is not limited herein specifically.
The enabling mark may be freely configured and may be freely selected, for example, the enabling mark is a file containing a character string, or a file with a special name, and the enabling mark is not particularly limited in the embodiment of the present application.
(2) In the case where the enablement flag is used to indicate enablement of the rights access control, a statistical interface is displayed based on the first interface data.
And the terminal acquires the enabling mark from the target partition in the Recovery mode, and determines whether to enable the permission access control according to the enabling mark. Under the condition that the enabling mark is used for indicating the permission access control is enabled, the terminal acquires first interface data from the Recovery data packet, renders the first interface data, displays a statistical interface and continues to refer to fig. 4.
And under the condition that the enabling mark is used for indicating that the permission access control is not enabled, the terminal executes Recovery operation on the data in the memory space based on the Recovery mode. Accordingly, the process may be: and under the condition that the enabling mark is used for indicating to execute Recovery operation on the data in the memory space, the terminal displays a data Recovery interface corresponding to the enabling mark based on the Recovery mode, the data Recovery interface displays a data Recovery entry, and the Recovery operation is executed on the data in the memory space in response to the data Recovery operation triggered by the data Recovery entry.
In the embodiment of the application, the mark password is input into the mark input interface, and whether the permission access control is started or not is determined according to the starting mark matched with the mark password, so that the occupation information can be obtained in the Recovery mode, and the use experience of a user is not influenced. And under the condition that the permission access control is not started, other operations can be performed in the Recovery mode, so that the flexibility is higher.
Step 304: and responding to the statistical operation triggered based on the statistical entry, and enabling the permission access control by the terminal in the Recovery mode based on the permission function data in the Recovery data packet.
The statistics interface displays a statistics entry, when the terminal detects the statistics operation triggered by the statistics entry, the terminal acquires authority function data from the Recovery data packet, and loads the authority function data, so that the authority access control is started in the Recovery mode, and the method continues to refer to fig. 4.
In the embodiment of the application, the data can be decrypted by adapting the authority function data to the Recovery mode, which is also a premise that the terminal can acquire the occupation information of the memory space in the embodiment of the application.
The permission access control may be a file-level encryption (FBE) control, and in the on state, the FBE control may encrypt data in the memory space to protect the data in the memory space, so that the data in the memory space is not normally readable by default. In the embodiment of the application, the FBE control is integrated into the Recovery mode, the data in the memory space is decrypted through the FBE control based on the strong execution authority of the Recovery, and the occupation information of the memory space is acquired by counting the space occupied by the decrypted data in the memory space.
In the embodiment of the application, the statistical interface is displayed with the statistical entry, and the user can automatically select the opportunity for starting the permission access control by triggering the statistical entry, so that the autonomous selectivity of the user is improved.
Step 305: and the terminal displays a lock screen checking interface based on the second interface data in the Recovery data packet.
The Recovery data packet further comprises second interface data, and the terminal obtains the second interface data from the Recovery data packet under the condition that the screen locking password is determined to be set, renders the second interface data and displays the screen locking verification interface.
The terminal acquires the input check password based on the screen locking check interface, compares the check password with a pre-stored screen locking password by using a gatekeeper native mechanism, and displays prompt information for prompting that the check is failed under the condition that the check is failed, and the terminal acquires the input check password again on the screen locking check interface until the check is passed. In case the verification passes, the terminal performs step 306.
The screen locking password may be a digital password, a pattern password, an alphabetic password, or a biometric password, such as a fingerprint password, which is not particularly limited. With continued reference to fig. 4, fig. 4 illustrates only the case where the screen locking code is a numeric code or a pattern code or an alphabetic code.
In the embodiment of the application, the screen locking password is bound with the key decrypted by the permission access control, and the decrypted key is acquired through the screen locking password, so that the data in the memory space can be accessed by the permission access control, and the comprehensiveness of acquiring the occupied information of the memory space is improved.
Step 306: and under the condition that the screen locking password is checked and passed based on the screen locking check interface, the terminal decrypts the first data in the memory space based on the permission access control to obtain third data.
The memory space comprises first data and second data, the first data is encrypted data, the second data is unencrypted data, and the terminal decrypts the first data through the permission access control under the condition that verification is passed, so that third data is obtained.
Because the memory space comprises a plurality of storage spaces, the first data can be distributed in one storage space or in a plurality of storage spaces, and the terminal can decrypt the first data in one or a plurality of storage spaces through the permission access control, so as to obtain decrypted third data. With continued reference to fig. 4, it can be seen from fig. 4 that: after the verification is passed, the terminal can decrypt the encrypted data through the permission access control.
In the embodiment of the application, the encrypted data can be decrypted through the permission access control, so that the comprehensiveness of acquiring the occupation information of the memory space can be improved according to the space occupied by the decrypted data and the unencrypted data in the memory space respectively.
Step 307: and the terminal acquires the occupation information of the memory space based on the space occupied by the second data and the third data in the memory space respectively.
In this step, the occupation information is used to represent the size of the space occupied by the data.
In one possible implementation manner, the terminal directly counts the space occupied by the second data and the third data in the memory space respectively, so as to obtain the occupation information of the memory space.
In the implementation manner, the terminal can directly count the space sizes occupied by the second data and the third data in the multiple storage spaces of the memory space through the statistical command in the first target script, so as to obtain the occupied information of the memory space.
In another possible implementation manner, the terminal preprocesses the second data and the third data, and obtains the occupation information of the memory space according to the space occupied by the preprocessed data in the memory space. Accordingly, the process may be achieved by the following steps (1) to (2), including:
(1) The terminal preprocesses the second data and the third data through a preprocessing command in the first target script to obtain fourth data and fifth data.
The preprocessing command may be a deletion command, a modification command, an addition command, a view command, or another linux command, and in the embodiment of the present application, the preprocessing command is not specifically limited. This preprocessing command is described here as an example of a deletion command and a modification command.
If the preprocessing command is a delete command, this step may be: and deleting the first type of data by the terminal through a deleting command in the first target script to obtain fourth data and fifth data, wherein the first type of data is data in the second data and the third data.
In this implementation manner, the deletion command may be a command for deleting data of a preset type, or may be a command for deleting data incompatible with other data in the current storage space, where the deletion command is not specifically limited.
The first type of data may be only data in the second data, may be only data in the third data, or may be a part of data in the second data and a part of data in the third data. If the first type of data is only the data in the second data, the fourth data is the data remaining after the first type of data is deleted in the second data, and the fifth data is still the third data. If the first type of data is only the data in the third data, the fifth data is the data remaining after the first type of data is deleted in the third data, and the fourth data is still the second data. If the first type of data is a part of the second data and a part of the third data, the fourth data is the data remaining after deleting a part of the second data, and the fifth data is the data remaining after deleting a part of the third data.
If the preprocessing command is a modification command, this step may be: and the terminal modifies the second type of data through the modification command in the first target script to obtain fourth data and fifth data, wherein the second type of data is the data in the second data and the third data.
In this implementation manner, the modification command may be a command for modifying a configuration file, or may be a command for modifying a file name, and the modification command is not specifically limited.
The second type of data may be only data in the second data, may be only data in the third data, or may be a part of the second data and a part of the third data.
(2) And the terminal acquires the occupation information of the memory space through the statistical command in the first target script based on the space occupied by the fourth data and the fifth data in the memory space respectively.
The terminal can count the space occupied by the fourth data and the fifth data which are obtained after preprocessing in a plurality of storage spaces of the memory space respectively through the statistical command in the first target script, and obtain the occupied information of the memory space. The occupation information is the occupation information of a plurality of storage spaces of the memory space.
For example, some storage spaces store video data, some storage spaces store audio data, some storage spaces store application data, and the terminal can count the space occupied by data in a plurality of storage spaces through a statistics command, so as to obtain occupation information of the plurality of storage spaces.
In another possible implementation manner, the terminal moves the storage space where the data is located, and obtains the occupation information of a plurality of storage spaces according to the space occupied by the moved data in the storage space. Accordingly, the process may be: the terminal moves the storage space in the memory space respectively by the movement command in the second target script; and acquiring the occupation information of a plurality of storage spaces in the memory space based on the space occupied by the moved second data and third data in the corresponding storage spaces respectively through the statistical command in the second target script.
In this implementation manner, the movement command may be a command for moving application data, or may be a command for moving preset type data, which is not limited specifically.
The terminal may move only the data in the second data, may move only the data in the third data, and may also move a part of the data in the second data and a part of the data in the third data, which is not limited specifically.
It should be noted that, in this implementation, the movement is a process of moving data from the first storage space to the second storage space, and after the data is moved, the occupation information of the second storage space and the first storage space will change, so the terminal obtains the occupation information of the plurality of storage spaces based on the space occupied by the moved second data and third data in the corresponding storage spaces respectively.
In the embodiment of the application, the terminal can also count the space occupied by the data based on other commands, so as to acquire the occupied information of the memory space. For example, the other command may be du, ls, stat or the like, and is not particularly limited. With continued reference to fig. 4, it can be seen from fig. 4 that: and the terminal calculates the data in the memory space by running the target script, so as to acquire the occupation information of the memory space.
In the embodiment of the application, the customized script can be operated according to the user requirement, and the data is counted through the corresponding script, so that the statistical requirement of the user is met.
The embodiment of the application provides a method for acquiring occupied information of a memory space, which comprises the steps of firstly controlling a terminal to enter a data recovery mode, starting an authority access control in the data recovery mode, checking a screen locking password based on a screen locking checking interface under the condition that the screen locking password is set by the terminal, and accessing data in the memory space based on the authority access control under the condition that the screen locking password is checked to pass the check. Because the screen locking password and the key decrypted by the permission access control have an association relationship, the decrypted key is acquired through the screen locking password, so that the permission access control can access the data with the access permission set in the memory space and the data without the access permission set in the memory space, and the occupation information of the memory space can be acquired based on the space occupied by the accessed data in the memory space, thereby improving the comprehensiveness of the occupation information of the statistical memory space.
In the embodiment of the application, after the terminal acquires the occupation information of the memory space, the terminal can perform exception analysis on the memory space according to the occupation information. Accordingly, the process may be: the terminal stores the occupation information into a target storage space of the terminal, derives the occupation information from the target storage space after exiting the Recovery mode, and performs exception analysis on the memory space based on the occupation information.
In this implementation manner, after acquiring the occupation information of the memory space in the Recovery mode, the terminal stores the occupation information into the target storage space, where the target storage space may be a storage space in the memory space or a storage space in another partition, which is not limited specifically. After exiting the Recovery mode, i.e. in the power-on state, the occupancy information is derived from the target storage space.
When the terminal derives the occupation information, the occupation information of the abnormal data can be highlighted and then fed back to the user, so that the data with abnormal occupation can be conveniently and accurately analyzed, and the method is continued to be shown in fig. 4. For example, the space occupied by a certain data is far more than the space occupied by other data in the storage space where the certain data is located, and in this case, the terminal can highlight the occupation information corresponding to the data. The highlighting may be at least one of bolded, enlarged, and a special color, which is not particularly limited.
The above description is given taking the terminal as an example to perform the abnormality analysis on the memory space based on the occupation information. In the embodiment of the application, the terminal can also send the occupation information to the server in a network feedback mode, correspondingly, the terminal is connected with the server through a wired or wireless network, the server receives the occupation information sent by the terminal, performs abnormal analysis on the memory space based on the occupation information, and then feeds back to the user in a statistical report mode or other modes.
The process of performing the anomaly analysis on the memory space by the server based on the occupation information is similar to the process of performing the anomaly analysis on the memory space by the terminal based on the occupation information, and is not described herein.
It should be noted that, the terminal through the permission access control not only can count the space occupied by the data in the memory space, but also can count at least one of the types of the data in the multiple storage spaces and the read-write permission to obtain the attribute information of the data in the memory space. And if the terminal acquires the attribute information and the occupancy information through the permission access control, the terminal stores the attribute information and the occupancy information into the target storage space together after acquiring the attribute information and the occupancy information, derives the attribute information and the occupancy information from the target storage space after exiting the Recovery mode, and performs anomaly analysis on the memory space based on the attribute information and the occupancy information.
In the implementation manner, the terminal can perform exception analysis on the memory space based on the attribute information and the occupation information, and can also send the attribute information and the occupation information to the server, and perform exception analysis on the memory space through the server, which is not particularly limited.
In the embodiment of the application, the strong execution authority of the Recovery mode is utilized, on the basis, the lock screen verification and the FBE decryption function are adapted to decrypt the data in the memory space, and then the space occupied by the data in the memory space is counted through the script to acquire the occupation information of the memory space. After exiting the Recovery mode, the occupation information is derived, so that the abnormal analysis is performed on the memory space based on the occupation information, and the analysis requirement on the abnormal occupation problem of the data in the memory space is met.
In summary, the method provided by the embodiment of the application can rapidly acquire the occupation condition of the memory space, shorten the problem processing period and greatly improve the analysis efficiency of the problem of abnormal occupation of the data in the memory space. In addition, the method controls the starting condition of the permission access control by inputting the mark password, and normal use experience of a user is not affected. In addition, the customized script can be run according to the requirements of users, various statistical functions can be realized in a diversified manner, and the method has good expansibility.
The following description will take the example that the terminal is not provided with the screen locking password. Fig. 5 is a flowchart of a method for obtaining occupancy information of a memory space according to an embodiment of the present application, which is executed by a terminal, and referring to fig. 5, the method includes:

Step 504: and responding to the statistical operation triggered based on the statistical entry, and enabling the permission access control by the terminal in the Recovery mode based on the permission function data in the Recovery data packet.
Steps 501 to 504 are the same as steps 301 to 304 described above and will not be described again here.
In the case that the terminal does not set the lock screen password, the terminal directly performs step 505.
Step 505: and the terminal decrypts the first data in the memory space based on the permission access control to obtain third data.
The process of decrypting the first data in the memory space and obtaining the third data by the terminal in step 306 based on the permission access control is the same, and will not be described here again.
