Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
Example 1
According to the method and the device, when the files on the terminal equipment are managed, the safety mode management can be introduced, namely after the files enter the safety mode, a user can select the corresponding files to carry out settings such as hiding and encryption, and therefore the safety and privacy of the files of the user are guaranteed.
Based on the above thought, the present embodiment provides a terminal device, which can perform security mode setting on a file, and at least includes a file management module and a file processing module that are connected to each other.
The file management module calls the file processing module to perform corresponding safety management operation on a specified single file or a plurality of files according to an instruction initiated by a user when the terminal equipment enters a file management safety mode;
wherein the security management operations include at least hiding and/or encryption operations.
Specifically, the file management module: when the terminal equipment enters a file management safety mode, safety management options are provided for a user, and the user initiates an instruction through the safety management options.
In this embodiment, the security management options provided by the file management module at least include hiding and/or encrypting options.
For example, when a user selects a single file or a plurality of files, security functions such as hiding, encryption and the like are selected through security management options.
When the user selects the hiding function, namely, the user initiates an instruction through the hiding option, the file management module prompts the user to input a password, and after the password is input and confirmed, the file processing module is called to hide the selected file (such as a picture and a video).
When the user selects the encryption function, namely, the user initiates an instruction through the encryption option, the file management module prompts the user to input a password, and calls the file processing module to encrypt the selected file at first after inputting and confirming the password.
In order to be compatible with the prior art, some preferred solutions propose a file management common mode, i.e. a mode without functions such as hiding, encryption, etc., when users and other applications have full operation rights. The general terminal equipment can be in a file management security mode by default and can be switched into a file management common mode according to user requirements.
The file processing module mainly carries out corresponding operation according to the calling of the file management module.
For example, when the user selects the hidden or encrypted security management option, the file management module prompts the user to input and confirm a password, and then the file processing module performs processing according to the call.
It should be noted that, when the file processing module operates the specified file according to the call, the hidden and encrypted file index table should be stored, and at the same time, the file management security mode, the common mode flag bit, and the like are stored, that is, a storage module is added.
Specifically, when the user selects the hidden option, a hidden file index table needs to be maintained in the storage module. Namely, the file which is selected to be hidden by the user is recorded in the hidden file index table, the file name, path, attribute and the like of the file are hidden, and then the address of the file which is selected to be hidden is returned, and the position of the hidden mark is '1' to indicate that the file is hidden. And the file list in the terminal equipment hides the files of the corresponding paths according to the hidden flag bits and the recording addresses.
Thus, when there is a hidden file (hidden flag is "1"), the file management module also provides a "show hidden" option among the management options. When the user selects 'display hide', the file management module prompts the user to input a password, and after the password is correct, the file management module traverses the hidden file index table and displays the hidden files one by one to the corresponding paths. Then, the flag position "0" is hidden.
When the encryption option is selected, the storage module maintains an index table of the encrypted file. That is, the file newly selected by the user to be encrypted is recorded in the encrypted file index table, which contains the name, path, attribute, etc. of the encrypted file, and the encryption flag bit is set to indicate that the file is encrypted. The encrypted file address is then returned. The encryption flag bit of the corresponding record is "1" at this time. When the file processing module encrypts the designated file, the file processing module can encrypt the designated file according to a preset encryption mode. For example, the system has its own encryption algorithm, etc.
When a user wants to copy, move and use a file, the file management module firstly traverses the encrypted file index table and prompts that the encrypted file cannot be operated when confirming that the file is encrypted.
When a user views an encrypted file, the option corresponding to the encrypted file (the encryption flag bit of the file is '1') displays 'decryption', at the moment, the user inputs a correct password to decrypt the encrypted file, the encryption flag bit is '0', and the encrypted file is deleted from the encrypted file index table.
Preferably, the terminal device may further include other application interaction modules, and in this case, the overall architecture of the terminal device is as shown in fig. 1. The other application interaction module can confirm that the picture or the video is displayed or not displayed according to the file attribute in other applications such as a gallery and a video library. The encrypted file in the file management module cannot be freely moved, copied, used, and the like, and other social apps cannot acquire the file authority. That is, when the terminal device is in the file management security mode, if the other application interaction module receives a file access request initiated by the user, the file to be accessed by the user is searched in the storage module, and if the file to be accessed by the user is searched in the storage module, the user is prompted to have no right to access.
Example 2
The embodiment provides a file management method of a terminal device, which mainly comprises the following operations:
when the terminal equipment enters a file management safety mode, the terminal equipment performs corresponding safety management operation on a specified single file or a plurality of files according to an instruction initiated by a user;
wherein the security management operations include at least hiding and/or encryption operations.
In addition, the terminal device provides a security management option for a user, and the user initiates an instruction through the security management option, wherein the security management option at least comprises a hiding and/or encryption option.
Specifically, when the user initiates an instruction through the hidden option, the terminal device further prompts the user to input a password, and after the user inputs the password and confirms the password, the user performs a hiding operation on the specified single file or multiple files.
When the user initiates an instruction through the encryption option, the terminal equipment also prompts the user to input a password, and when the user inputs the password and confirms the password, encryption operation is carried out on the appointed single file or a plurality of files.
When the terminal device performs corresponding security management operations on a specified single file or multiple files according to an instruction initiated by a user, the terminal device also needs to store a hidden and encrypted file index table. Therefore, when the terminal equipment is in a file management safety mode, if a file access request initiated by a user is received, a file to be accessed by the user is searched in the stored hidden and encrypted file index table, and if the file to be accessed by the user is searched, the user is prompted to have no right to access.
The following describes in detail the implementation process of the above method with reference to a specific application scenario and fig. 2, and the process includes the following steps:
The terminal device defaults to a safety mode, and the user can also switch to enter a common mode.
It should be noted that, the steps 202 and 203 are executed according to user operation, and are not necessarily executed according to the time sequence, and the operation of the step 203 may be first performed, and then the operation of the step 202 is performed.
In addition, a file that is hidden according to the above-described method (i.e., a hidden file) will not be displayed in an application such as a gallery, video library, or the like. The hidden file can only be displayed when the user selects the "show hide" option and enters the correct password.
Likewise, a file encrypted according to the above-described method (i.e., an encrypted file) will not be removable, duplicative, disposable, etc. And part of social apps cannot acquire the encrypted file authority. Only if the user selects the "decrypt" option and enters the correct password can the encrypted file be decrypted and displayed.
Since the method can be implemented according to the terminal device in embodiment 1, other detailed operations of the method can be referred to corresponding contents of embodiment 1, and are not described herein again.
It will be understood by those skilled in the art that all or part of the steps of the above methods may be implemented by instructing the relevant hardware through a program, and the program may be stored in a computer readable storage medium, such as a read-only memory, a magnetic or optical disk, and the like. Alternatively, all or part of the steps of the above embodiments may be implemented using one or more integrated circuits. Accordingly, each module/unit in the above embodiments may be implemented in the form of hardware, and may also be implemented in the form of a software functional module. The present application is not limited to any specific form of hardware or software combination.
The above description is only a preferred example of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
