Detailed Description
The invention discloses a file access protection method and system based on a mobile terminal and the mobile terminal, and in order to make the purpose, technical scheme and advantages of the invention clearer and more clear, the invention is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a file access protection method based on a mobile terminal according to a preferred embodiment of the present invention. The file access protection method based on the mobile terminal shown in fig. 1 includes:
step S101, the mobile terminal sets a locking mark for the stored file in advance.
In the embodiment of the present invention, a file and attribute information corresponding to the file need to be set and stored in the mobile terminal in advance, where the attribute information includes: a file name, a file storage path, and a lock flag for the file, the lock flag comprising: locking, and unlocking.
Further, the step S101 specifically includes:
s11, starting the mobile terminal, and starting a Daemon process for locking/unlocking the file;
s12, when the mobile terminal starts an application program, the application program establishes connection with the Daemon process;
s13, the application program sends files needing to be locked/unlocked and attribute information corresponding to the files to a Daemon process;
s14, calling a mobile terminal kernel layer interface by the Daemon process, and sending the received file and the attribute information corresponding to the file to the mobile terminal kernel layer;
and S15, the mobile terminal kernel layer performs locking setting or unlocking null setting operation on the corresponding node attribute flag bit in the file system where the file is located.
Taking the mobile phone of android as an example, the user file is generally established on sdcard. When accessing the file, the bottom layer, namely the linux kernel layer, is needed to open the node of the file system where the file is located, then the flag bit of the file is verified, whether the user has the right of being able to read and write is judged, and if so, the operations of reading and writing and the like can be further performed. Based on the method, the files required to be locked by the user are directly marked on the kernel layer, and the marked result is stored in the file system. After the setup is completed, when the command to access the file reaches the kernel level, we verify that the file has the lock flag. If so, access is denied. Similarly, after the file is unlocked, the mark originally stored in the file system after being locked is deleted, and the file is restored to the state of the ordinary file.
The flow of setting file locking/unlocking according to the embodiment of the present invention is shown in fig. 2. Firstly, when the mobile phone is started, a Daemon process is started, the Daemon process is mainly responsible for managing the locking and unlocking states of files, and can receive commands of application programs and interact with a kernel layer. When the file is required to be locked/unlocked, the user operates the application program and issues a locking/unlocking command. The application will establish a connection with the previously started Daemon in a socket or any other inter-process communication manner. After the connection is successfully established, the application program sends a file path, a file name and a locking command which need to be locked/unlocked to Daemon for further processing. Meanwhile, the application program can also ask Daemon for the state of the current file, whether the current file is in a locked or unlocked state.
And step S102, when the mobile terminal receives a command of opening the file, acquiring a locking mark of the current file, and judging whether the current file is locked.
Further, the step S102 specifically includes:
s21, the mobile terminal receives a command of opening a file by an application program;
s22, the command reaches a mobile terminal kernel layer, and the mobile terminal kernel layer searches a node attribute zone bit of the current file according to the current file path and the file name;
and S23, judging whether the current file is locked or not according to the node attribute zone bit.
That is, after receiving the application command, Daemon calls an interface of the kernel layer, and the interface can be completed by using a standard interface provided by the kernel or added by a developer. And transmitting a file name and a path to the kernel through the interface, and locking, unlocking and acquiring the locking state of the file. Thereafter, logical processing at the kernel layer is triggered. Setting or clearing (locking setting and unlocking null) the corresponding node attribute flag bit of the file in the file system to which the file belongs. This attribute may use existing flags provided by the file system or may be added by the developer himself. If the upper layer issues the query status command, the flag bit information is returned.
Step S103, if the file is locked, executing a preset file protection process; otherwise, the file is opened normally.
Further, the step S103 specifically includes:
s31, if the node attribute flag bit of the current file is detected to be set, interrupting a file opening command, and displaying a message that the current file is locked on a screen of the mobile terminal through a push mechanism;
and S32, if the node attribute flag bit of the current file is detected to be null, normally opening the file.
That is, after the file lock is successfully set, if the user needs to access the locked file, the process of authority verification is triggered, which specifically includes: if the flag bit is not set, the file is unlocked, and only the ordinary file is used, the processing is continued according to the flow of the ordinary file; if the setting is found, the file is locked, the next operation is interrupted, an error code without access authority is returned, and meanwhile, the driving layer reports the event to a frame layer of the android mobile phone, wherein the event comprises information such as a file name, a path, a locking state and the like; a certain service at the frame layer needs to listen to events of this type of file lock at all times. Once the event is received, the fact that the file is locked needs to be reported to the user interface by using the notification mechanism (message pushing mechanism) of the mobile phone.
The invention will be further illustrated by the following specific application examples. Fig. 3 is a schematic diagram of an application embodiment of the file access protection method based on the mobile terminal of the present invention. As shown in fig. 3, includes:
s301, opening a file by an application program; for example, a user needs to open a photo through a picture browser;
s302, executing an open command driven by a file system; firstly, an image browser image browsing program must open the file through an open command, and after the open command reaches a kernel, an open method of a kernel layer is triggered;
s303, detecting a flag bit of file locking;
s304, judging whether the file is locked or not; if yes, go to step S306, otherwise, go to step S305;
s305, if the file is detected to be unlocked, continuing to operate as a common file, and entering the step S309; that is, if the flag bit is not set, it indicates that the file is not locked, and only the ordinary file is used, the flow processing according to the ordinary file is continued;
s306, if the file is detected to be locked, the operation is abandoned, and a notice without permission is returned; that is, if the set is found, indicating that the file is locked, then the command to open the file is interrupted;
s307, reporting the notification that the file is locked; the mobile phone driver layer reports the event to the frame layer, wherein the event comprises information such as a file name, a path, a locking state and the like;
s308, pushing the locked file message and informing the user;
and S309, finishing the operation.
The embodiment of the invention is to prevent a user from reading and writing a locked file and take file access protection measures, if the file needs to be protected from being deleted maliciously, the basic flow is consistent with the flow shown in fig. 3, only in a kernel layer, a mark for file locking needs to be verified in a mobile phone unlink method, and the rest is the same as the logic in the reading and writing flow, and is not repeated.
Therefore, compared with the traditional file secrecy cabinet, the file secrecy cabinet has the following advantages:
(1) no extra storage space is occupied;
(2) a large amount of time necessary for encryption/decryption is saved;
(3) the position of the original file is not required to be changed;
(4) the file folder may be locked.
