Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is one of the flowcharts of the encryption and decryption method provided by the embodiment of the present invention. As shown in FIG. 1, the method is applied to a mobile terminal and includes the following steps:

Step 101. Detect whether the arrangement state of the objects in the target folder has changed.

The embodiment of the present invention can be adapted to any object in the mobile terminal, that is, the embodiment of the present invention can perform encryption and decryption control on any object in the mobile terminal. For example, the object may be an application program APP (such as social APP, payment APP, media player or browser, etc.) stored in the mobile terminal, or various files stored in the mobile terminal (such as pictures, audio, video or documents, etc.).

In the embodiment of the present invention, the purpose of encrypting or decrypting the target objects in the target folder is achieved by setting the target folder and the arrangement state of the objects in the target folder.

Here, the target object is different from the ordinary object, which can be viewed or used at will, and the target object can only be viewed or used in the decrypted state, but cannot be viewed or used in the encrypted state.

Similarly, the target folder is different from ordinary folders. The arrangement state of the objects in the target folder determines whether the target objects in the target folder are in the encrypted state or the decrypted state.

The number of target folders in the mobile terminal may be at least one, and the number of target objects in each target folder may also be at least one. The target folder can be any folder in the mobile terminal, for example, an album folder for organizing pictures, a folder for organizing documents, and a desktop folder for organizing APPs set on the desktop of the mobile terminal, and many more.

Wherein, the arrangement state of the objects in the target folder may include at least one of the following: the name of the objects in the target folder; the number of objects in the target folder; the arrangement order of the objects in the target folder; Arrange shapes. Users can set arrangement states of varying degrees of complexity according to encryption requirements.

The embodiment of the present invention focuses on the method of decrypting the target object in the encrypted state, which will be described in detail from step 101 to step 103 respectively below.

In this step, the mobile terminal can detect whether there is a change in the arrangement state of the objects in the target folder. It can be understood that the target object in the current target folder is in an encrypted state. If it is detected that there is a change in the arrangement state of the objects in the target folder, continue to execute step 102; if it is not detected that there is a change in the arrangement state of the objects in the target folder, then end the process.

Step 102: If it is detected that the arrangement state of the objects in the target folder has changed, compare the changed arrangement state of the objects in the target folder with the preset decrypted arrangement state.

In step 101, if the mobile terminal detects that there is a change in the arrangement state of the objects in the target folder, then in this step, the mobile terminal can obtain the changed arrangement state of the objects in the target folder, and store the changed The arrangement state of the objects in the target folder is compared with the decrypted arrangement state.

Wherein, the decryption arrangement state may be preset by the user. After setting, the decryption arrangement state becomes the password of the target object in the decryption target folder. At any time, the user can change the previously set decryption arrangement status.

Step 103: If the arrangement state of the objects in the target folder matches the decryption arrangement state, set the target objects in the encrypted state in the target folder to the decrypted state.

In step 102, if the arrangement state of the objects in the target folder matches the decryption arrangement state, then in this step, the mobile terminal may set the target objects in the encrypted state in the target folder to the decrypted state. It can be understood that the start permission and/or operation permission of the target object in the encrypted state is closed.

So far, the decryption of the target object in the target folder is completed, and the user can view or use the target object in the target folder.

It can be seen that the user can make the mobile terminal decrypt the encrypted target object by adjusting the arrangement state of the objects in the target folder. It is easy to understand that the user (or mobile terminal) can also make the mobile terminal encrypt the target object in the decrypted state by adjusting the arrangement state of the objects in the target folder, so that the privacy protection of the target object can be realized; The target folder controls multiple target objects in a unified way, which improves the control efficiency of the mobile terminal on the target objects compared to the separate control of a single target object; the arrangement of the objects in the target folder is used as the means of encryption and decryption. Not only is it intuitive and easy to operate for users, but it is also difficult for others to detect, which improves the security of target object encryption

In the embodiment of the present invention, the above-mentioned mobile terminal can be any device with folder setting function, for example: computer (Computer), mobile phone, tablet computer (Tablet Personal Computer), laptop computer (LaptopComputer), personal digital assistant (personal digital assistant) digital assistant (PDA for short), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device), etc.

The encryption and decryption method of the embodiment of the present invention detects whether there is a change in the arrangement state of the objects in the target folder; if it is detected that the arrangement state of the objects in the target folder changes, the changed target file Compare the arrangement state of the objects in the folder with the preset decryption arrangement state; if the arrangement state of the objects in the target folder matches the decryption arrangement state, then the The target object in the encrypted state is set to the decrypted state. In this way, the embodiment of the present invention pre-sets the decryption arrangement state for decrypting the target object, and when the arrangement state of the object in the target folder matches the decryption arrangement state, the target object is decrypted; otherwise, the target object is decrypted. Objects are encrypted. It can be seen that the embodiment of the present invention can realize the privacy protection of the target object; multiple target objects can be controlled uniformly through the target folder, which improves the control of the target object by the mobile terminal compared with controlling a single target object separately. Efficiency: Using the arrangement of objects in the target folder as the means of encryption and decryption is not only intuitive and easy to operate for users, but also difficult for others to detect, which improves the security of target object encryption.

Referring to FIG. 2, FIG. 2 is the second flow chart of the encryption and decryption method provided by the embodiment of the present invention. As shown in FIG. 2, the method is applied to a mobile terminal and includes the following steps:

Step 201, receiving the encryption information of the target folder input by the user.

Wherein, the encryption information includes: at least one target object corresponding to the target folder, a decryption arrangement state corresponding to the target folder, and at least one encryption arrangement state corresponding to the target folder.

In the embodiment of the present invention, the user may pre-set corresponding encrypted information for the target folder, and the encrypted information may include at least one target object corresponding to the target folder, and a decryption arrangement state corresponding to the target folder. In the process of presetting the encrypted information, the user can set the number of objects contained in the target folder, which target objects are specifically contained in the target folder, and other information according to the needs of the user. At any time, the user can change the previously set encrypted information to update the encrypted information.

In the embodiment of the present invention, by setting the encrypted information for the target folder in advance, the user can flexibly set the encrypted information according to his own habits and needs.

The embodiment of the present invention can be adapted to any object in the mobile terminal, that is, the embodiment of the present invention can perform encryption and decryption control on any object in the mobile terminal. For example, the object may be an application program APP (such as social APP, payment APP, media player or browser, etc.) stored in the mobile terminal, or various files stored in the mobile terminal (such as pictures, audio, video or documents, etc.).

For example, the user can set at least one target object corresponding to the target folder as: SMS APP, WeChat APP, phone APP and photo album APP, and the user can set the decryption arrangement state corresponding to the target folder to include only the above four The order of the APPs is not limited. The user can set at least one encrypted arrangement state corresponding to the target folder, including: moving any one of the above four APPs out of the target folder and adding at least one in the target folder. Other apps.

Step 202, detecting an object move operation on the target folder.

In the embodiment of the present invention, the purpose of encrypting or decrypting the target objects in the target folder is achieved by setting the target folder and the arrangement state of the objects in the target folder.

Wherein, the arrangement state of the objects in the target folder may include at least one of the following: the name of the objects in the target folder; the number of objects in the target folder; the arrangement order of the objects in the target folder; Arrange shapes. Users can set arrangement states of varying degrees of complexity according to encryption requirements.

The embodiment of the present invention focuses on the method of decrypting the target object in the encrypted state, which will be described in detail from step 202 to step 204 respectively below.

In this step, the mobile terminal can detect the object moving operation to the target folder, which can be understood as that the target object in the current target folder is in an encrypted state. If an object move operation to the target folder is detected, it indicates that the arrangement state of the objects in the target folder has changed, and then proceed to step 203; if an object move operation to the target folder is not detected, it indicates that the target folder If there is no change in the arrangement state of the objects, the process ends.

Optionally, the object moving operation in step 202 includes at least one of the following:

an operation of moving at least one object into said target folder;

the act of moving at least one object out of said target folder;

An operation of moving the position of at least one object in the target folder in the target folder.

In the embodiment of the present invention, the object moving operation to the target folder may be the operation of moving at least one object into the target folder, or the operation of moving at least one object out of the target folder, or the operation of moving the The operation of the position of at least one object in the target folder in the target folder may also be a combination of any two or more of the above operations. The above object moving operation is highly operable, and the operation is simple and fast.

For example, after the user has set the encryption information of the target folder in step 201, an encryption instruction input by the user is received, and the target object of the target folder is set to an encrypted state. For example, it may be to add a game APP in the target file including SMS APP, WeChat APP, phone APP and photo album APP, and move the phone APP out of the target folder.

After the user enters the encryption command, the user cannot start and/or operate the SMS APP, WeChat APP, phone APP and photo album APP.

If the user needs to start and/or operate the target object in the encrypted state, the arrangement state in the target folder needs to be adjusted to the decrypted arrangement state. That is to say, in step 202, the user can move the object in the target folder, for example, the game APP in the target folder can be moved out of the target folder, and the phone APP can be moved back into the target folder.

Step 203: If the object movement operation is detected, compare the arrangement state of the objects in the target folder after the object movement operation with the preset decryption arrangement state.

In step 202, if the mobile terminal detects an object moving operation on the target folder, then in this step, the mobile terminal may acquire the arrangement state of the objects in the target folder after the object moving operation, and store the acquired The arrangement state is compared with the decrypted arrangement state.

Wherein, the decryption arrangement state may be preset by the user. After setting, the decryption arrangement state becomes the password of the target object in the decryption target folder. At any time, the user can change the previously set decryption arrangement status.

For example, after the user moves the objects in the target folder in step 202, the mobile terminal may compare the arrangement state after the move operation with the decrypted arrangement state set in step 201.

If the user moves the game APP in the target folder out of the target folder, and moves the phone APP back into the target folder, the arrangement state after the move operation matches the decryption arrangement state set in step 201 . Otherwise, there is no match.

Step 204: If the arrangement state of the objects in the target folder matches the decryption arrangement state, set the target objects in the encrypted state in the target folder to the decrypted state.

In step 203, if the arrangement state of the objects in the target folder matches the decryption arrangement state, then in this step, the mobile terminal can set the target objects in the encrypted state in the target folder to the decrypted state, thus being able to Realize the privacy protection of the target object; multiple target objects can be controlled uniformly through the target folder, which improves the control efficiency of the mobile terminal to the target object compared to the separate control of a single target object; As an encryption and decryption means, the arrangement state of objects is not only intuitive and easy to operate for users, but also difficult for others to detect, which improves the security of target object encryption.

For example, if the user moves the game APP in the target folder out of the target folder, and moves the phone APP back into the target folder, the arrangement state of the objects in the target folder matches the decrypted arrangement state, and the object in the target folder The SMS APP, WeChat APP, phone APP and photo album APP of the four APPs have all changed from encrypted status to decrypted status, and users can start and/or operate any of them.

So far, the decryption of the target object in the target folder is completed, and the user can view or use the target object in the target folder.

It can be seen that the user can adjust the arrangement state of the objects in the target folder by moving the objects in the target folder, so that the mobile terminal can decrypt the target objects in the encrypted state. It is easy to understand that the user (or mobile terminal) can also adjust the arrangement state of the objects in the target folder by moving the objects in the target folder, so that the mobile terminal can encrypt the target objects in the decrypted state.

In this embodiment of the present invention, except for steps 201 to 203, other steps may be the same as the embodiment of the invention shown in FIG. 1 , and to avoid repetition, the same parts are not repeated.

As a better encryption and decryption method, one or several target objects can be regarded as a set, and only when the target folder contains all corresponding target objects, the user can open the target in the target folder The object, that is, the decrypted arrangement state is the arrangement state in which all corresponding target objects are included in the target folder.

The user or the mobile terminal can move one or several target objects out of the target folder, or move one or several common objects into the target folder, or adjust the order of the target objects in the target folder, or Move one or several target objects corresponding to other target folders different from the target folder into the target folder, etc., to achieve the purpose of encryption.

When the user needs to decrypt the target objects in the target folder, the reverse operation can be performed, for example, moving a certain target object or some target objects that have been moved out to the target folder again, or moving the normal objects that have been moved out of the target folder, Either adjust the order of the target objects in the target folder to the correct order, or move the target objects corresponding to other target folders that are different from the target folder out of the target folder, and so on.

Optionally, the target folder is displayed with an encryption mark.

In the embodiment of the present invention, the mobile terminal can display the encryption mark on the target folder. As shown in FIG. 2-1, an encryption mark 211 is displayed in the upper left corner of the target folder, which is convenient for the user to distinguish the target folder from the normal folder.

In addition, the encryption logo can change with the encryption attribute of the folder. When the encryption function of the folder is turned on, the encryption logo can be displayed on the target folder; when the encryption function of the folder is turned off, the encryption logo of the folder can be disappear.

It should be noted that the specific display form of the encrypted identifier is not limited to the form shown in Figure 2-1.

The implementation manner of the present invention may also be implemented in combination with the embodiment shown in FIG. 1 , which will not be described in detail to avoid repetition.

Optionally, operation buttons are displayed in the target folder, and the operation buttons include at least one of a configuration button, a move-in button or a move-out button, or a move-in and move-out button.

In the embodiment of the present invention, the mobile terminal can display operation buttons in the target folder, as shown in FIG. 2-2 , so that the user can perform corresponding operations through the operation buttons. Wherein, the operation button may be a configuration button, as shown in FIG. 2-2, there is a configuration button 221 displayed on the upper left of the target folder, and the configuration button 221 can be used to configure encrypted information for the target folder. The operation button can also be a move-in button 222, and the move-in button 222 can help the user move the object into the target folder; the move-in button 222 can also be a move-out button, which can help the user move the object out of the target folder; the move-in button 222 can also be a move-in and move-out button , which helps the user move objects into or out of the target folder. The user can also directly move any object in the target folder out of the target folder by dragging, or move any object outside the target folder into the folder by dragging.

It should be noted that the specific display form of the operation button is not limited to the form shown in FIG. 2-2.

The implementation manner of the present invention may also be implemented in combination with the embodiment shown in FIG. 1 , which will not be described in detail to avoid repetition.

The encryption and decryption method of the embodiment of the present invention detects the object moving operation on the target folder; if the object moving operation is detected, the arrangement state of the objects in the target folder after the object moving operation is Compare with the decryption arrangement state; if the arrangement state of the object in the target folder matches the decryption arrangement state, set the target object in the encrypted state in the target folder as decryption state. In this way, the embodiment of the present invention pre-sets the decryption arrangement state for decrypting the target object, and when the arrangement state of the object in the target folder matches the decryption arrangement state, the target object is decrypted; otherwise, the target object is decrypted. Objects are encrypted. It can be seen that the embodiment of the present invention can realize the privacy protection of the target object; multiple target objects can be controlled uniformly through the target folder, which improves the control of the target object by the mobile terminal compared with controlling a single target object separately. Efficiency: Using the arrangement of objects in the target folder as the means of encryption and decryption is not only intuitive and easy to operate for users, but also difficult for others to detect, which improves the security of target object encryption.

Referring to FIG. 3, FIG. 3 is the third flowchart of the encryption and decryption method provided by the embodiment of the present invention. As shown in FIG. 3, the method is applied to a mobile terminal and includes the following steps:

Step 301, detecting whether there is a change in the arrangement state of objects in the target folder.

In this embodiment of the present invention, the arrangement status of objects in the target folder may include at least one of the following:

the name of the object in the target folder;

the number of objects in the target folder;

Sort order of objects in the target folder;

Arrangement shape of objects in the target folder.

Users can set arrangement states of varying degrees of complexity according to encryption requirements.

The embodiment of the present invention focuses on the method of decrypting the target object in the encrypted state and encrypting the target object in the decrypted state, which will be described in detail from step 301 to step 306 respectively below.

In this step, the mobile terminal can detect whether there is a change in the arrangement state of the objects in the target folder. It can be understood that the target object in the current target folder is in an encrypted state. If it is detected that there is a change in the arrangement state of the objects in the target folder, continue to execute step 302; if it is not detected that there is a change in the arrangement state of the objects in the target folder, then end the process.

Step 302: If it is detected that the arrangement state of the objects in the target folder has changed, compare the changed arrangement state of the objects in the target folder with the preset decryption arrangement state.

In step 301, if the mobile terminal detects that there is a change in the arrangement state of the objects in the target folder, then in this step, the mobile terminal can obtain the changed arrangement state of the objects in the target folder, and store the changed The arrangement state of the objects in the target folder is compared with the decrypted arrangement state.

Step 303: If the arrangement state of the objects in the target folder matches the decryption arrangement state, set the target objects in the encrypted state in the target folder to the decrypted state.

In step 302, if the arrangement state of the objects in the target folder matches the decryption arrangement state, then in this step, the mobile terminal may set the target objects in the encrypted state in the target folder to the decrypted state.

Step 304, detecting a trigger instruction.

In this step, the mobile terminal may detect the trigger instruction. Wherein, the triggering instruction is a preset instruction for triggering the encryption of the target object.

Here, the trigger instruction may be an instruction corresponding to turning off the screen of the mobile terminal, an instruction corresponding to locking the screen of the mobile terminal, an instruction corresponding to shutting down or restarting the mobile terminal, or an instruction corresponding to the mobile terminal receiving a certain user operation (such as Instructions for click operations on trigger buttons, gesture graphics, etc.).

Step 305, if the trigger instruction is detected, set the target object in the decrypted state in the target folder to be encrypted.

In step 304, if the mobile terminal detects the trigger instruction, then in this step, the mobile terminal may respond to the trigger instruction and set the target object in the decrypted state in the target folder to an encrypted state. At this time, the target object in the target folder changes from a decrypted state to an encrypted state, and the user cannot view or use the target object in the target folder. It can be understood that the launch authority and/or operation authority of the target object in the decrypted state is enabled.

Step 306. Adjust the arrangement state of the objects in the target folder to a preset first encrypted arrangement state.

Because the embodiment of the present invention achieves the purpose of encrypting or decrypting the target objects in the target folder by setting the target folder and the arrangement state of the objects in the target folder. In step 305, the target object in the target folder is changed from a decrypted state to an encrypted state. Correspondingly, in this step, the mobile terminal needs to adjust the arrangement state of the objects in the target folder, that is, the target The arrangement state of the objects in the folder is adjusted to the first encrypted arrangement state.

It should be noted that the sequence of execution of step 305 and step 306 in the embodiment of the present invention is not limited, step 306 may be executed after step 305 is executed, step 305 may be executed after step 306 is executed, or step 305 may be executed simultaneously and step 306. Figure 3 shows the simultaneous execution.

Wherein, the first encryption arrangement state may be preset by the user or the mobile terminal, and at least one first encryption arrangement state may be set for each target folder. When there are two or more first encryption arrangement states corresponding to a target folder, the mobile terminal may randomly select any one of the first encryption arrangement states. Setting a plurality of first encryption arrangement states for each target folder is beneficial to improve the degree of encryption.

In the embodiment of the present invention, except for step 303 to step 306, other steps may be the same as the embodiment of the invention shown in FIG. 1 or FIG. 2 , and to avoid repetition, the same parts will not be repeated.

Optionally, the step of detecting whether there is a change in the arrangement state of the objects in the target folder includes:
