Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
Fig. 1 is a schematic view of an optional application management method according to the present invention. As shown in fig. 1, in the present embodiment, an open system and a private system are provided in a terminal device, wherein a private folder is provided in the private system, and a public folder is provided in the open system. Fig. 1 shows an interface for managing the memory of the terminal device in the private system, where the interface shows that the private system may include a private photo folder, a private contact folder, a private short message folder, a private video folder, and a private audio folder. The user can only read and write the private folder after entering the private system, and if the user is in the open system, the user does not have the authority to read and write the private folder.
Fig. 2 is a flowchart illustrating a method for managing data files of a private system according to an exemplary embodiment of the present invention. As shown in fig. 2, the method for managing data files of a private system provided in this embodiment includes:
Specifically, the terminal device may obtain system information of a system operated by the current terminal device, and then determine whether the system operated by the current terminal device is a private system by comparing the system information with system information in a preset list. For example, if the system name of the open system set in the terminal device is KF and the system name of the private system set in the terminal device is SM, if the system name in the system information of the system operated by the current terminal device, which is acquired by the terminal device, is KF, it is determined that the system operated by the current terminal device is the open system; and if the system name in the system information of the system operated by the current terminal equipment, which is acquired by the terminal equipment, is SM, determining that the system operated by the current terminal equipment is a private system.
Usually, when a user selects to enter a private system, the user also needs to pass corresponding identity authentication. After the terminal device receives a private system starting instruction for starting the private system by a user, prompt information for prompting the user to input authentication information is output to the user, wherein specific prompt information can be that the user inputs a corresponding password, inputs a fingerprint or inputs a face. After the user obtains the input authentication information prompt information provided by the terminal device, the user can input corresponding authentication information according to the prompt, the authentication information can be a character password, such as a pure digital password, or a combination of a number and a letter, and can also be biological characteristics such as fingerprint information, iris information or face information, wherein the security of the private system can be higher by adopting the biological characteristics.
After the terminal equipment acquires the identity authentication information input by the user, the terminal equipment judges whether the identity authentication information input by the user is consistent with the preset identity authentication information or not, and if the judgment result is yes, the private system is started; if the judgment result is negative, the terminal equipment locks the private system. In order to prevent unexpected errors in the process of inputting the user identification verification information, when the terminal equipment judges that the authentication information input by the user is inconsistent with the preset authentication information for the first time, the terminal equipment prompts the user to input the user identification verification information again, the user can input the user identification verification information again according to the prompt, and when the user identification verification information input by the user is continuously incorrect, the terminal equipment locks the private system.
And 102, the terminal equipment opens the read-write permission of the private folder.
Specifically, when the terminal device determines that the currently started system is the private system, the terminal device will open the read-write permission of the private folder, so that the private folder can be accessed in the private system. And after the terminal device obtains the private system closing instruction input by the user, the terminal device will quit the private system, at this moment, the terminal device will close the read-write permission of all the private folders according to the private system closing instruction, and then the terminal device will quit from the private system and enter the open system. In the open system, the read-write authority of the private folder is in a closed state, so that in the open system, a user cannot perform any read-write operation on the data file in the private folder.
In this embodiment, whether to open the read-write permission of the private folder is determined by judging whether the system currently operated by the terminal device is a private system or an open system, and when the system currently operated by the terminal device is the private system, the read-write permission of the private folder is opened, and when the system currently operated by the terminal device is the open system, the read-write permission of the private folder is closed. By controlling the read-write access authority of the private folder, each application or process can not access the data file in the folder in the open system, so that indirect encryption is realized, and when the private system is accessed, the read-write access authority of each private folder is opened, but because the data file in the private folder is not encrypted in the private system, an additional decryption process is not needed during reading and writing, the realization is very efficient and simple, and the read-write speed of the data file in the private system is greatly improved.
Based on the embodiment shown in fig. 2, fig. 3 is a flowchart illustrating a method for managing data files of a privacy system according to another exemplary embodiment of the present invention. As shown in FIG. 3, the present embodiment provides
It should be noted that, the specific implementation manner of the steps 201-202 refers to the description of the steps 101-102 in the first embodiment, and is not described herein again.
Specifically, the terminal device obtains a private folder access instruction input by a user in the private system, where the access instruction may be an instruction triggered by the user clicking a private folder through a touch screen, or may also be an instruction for the user to open a corresponding private folder through voice control, and it is worth to say that, in this embodiment, a specific limitation is not performed on a manner in which the user inputs the private folder access instruction.
And step 204, the terminal equipment starts a private application program corresponding to the private folder according to the private folder access instruction.
After the terminal device receives a private folder access instruction input by a user, the terminal device starts a private application program corresponding to the private folder, wherein the private folder is used for storing data files of the private application program. For example, after the user clicks a contact private file, the terminal device starts a contact application, and then the user can access the private contact through the contact application; after the user clicks the short message private file, the terminal equipment starts the short message application, and then the user can access the private short message through the short message application; after the user clicks the private photo, video or audio file, the terminal device starts an application for viewing pictures, playing videos or playing audios, and then the user can access the private photo, video or audio through a short message application of the application for viewing pictures, playing videos or playing audios.
When the user needs to transfer the data file in the open system to the private folder, the user can make the file in a floating state by long-pressing the file, and then drag the file to the private folder. For example, a user may select a photo in the photo public folder and then drag copy it into the photo private folder.
And step 206, the terminal equipment moves the data files in the public folder to the private folder according to the data file moving instruction.
After the terminal equipment completes the movement of the data file, the terminal acquires the storage path of the data file in the public folder, establishes a mapping relation between the file name and the storage path of the data file and stores the mapping relation in a file path database. For example, for a photo with a file name of "landscape" originally stored in the "photo \ a public folder" storage path, after moving, the "landscape" corresponding to the "photo \ a public folder" is recorded in the file path database.
And step 208, the terminal equipment deletes the data file in the public folder and updates the file list of the private application program.
After the terminal device completes the action of moving the data file, in order to better protect the privacy of the data file, the terminal device deletes the data file in the public folder and updates the file list of the private application program.
And step 209, the terminal equipment loads the data file in the private folder according to the file list of the private application program.
When the user needs to transfer the data file in the private folder to the public folder, the user can enable the file to be in a floating state through the file, and then selects the 'public' option, so that the terminal device can transfer the data file to the corresponding public folder. For example, the user may long press a photo in the photo private folder, so that the photo is in a floating state, and then select the "public" option.
And step 211, the terminal device acquires the file name of the data file according to the data file reduction instruction.
After the user triggers the data file reduction instruction, the terminal equipment acquires the file name of the data file according to the data file reduction instruction.
And step 212, the terminal device screens out a storage path corresponding to the data file according to the file name of the data file and the file path database.
After the terminal device obtains the file name of the file to be restored, the storage path corresponding to the data file is screened out according to the file name of the data file and the file path database. For example, if the user needs to restore a photo with a "landscape" file name to the public folder, the terminal device will screen out the "landscape" corresponding to the "photo \ a public folder in the file path database, so as to determine that the path of the original storage of the photo with the" landscape "file name is the" photo \ a public folder ".
And step 213, the terminal device moves the data file to the public folder according to the storage path.
And step 214, the terminal equipment deletes the data file in the private folder.
