First embodiment

Fig. 1 is a flowchart illustrating a privacy protecting method of a terminal according to a first embodiment. Referring to fig. 1, the privacy protection method for a terminal of the present embodiment includes:

step 110, receiving operation information.

The operation information is information generated by the terminal receiving a user operation, such as an operation signal of pressing an entity key, a signal of clicking an interface, password information included when a password is input, fingerprint information included when a fingerprint is input, a face image included when a face is recognized, and the like.

And step 120, matching the operation information with the privacy protection rule of the target file.

The privacy protection rule defines a corresponding relationship between the operation information and the privacy protection operation of a target file in advance, the target file is a file in which the privacy protection rule is defined in advance, the target file includes but is not limited to files and folders in the terminal, the files can be pictures, documents, compressed packets, videos and the like, and one or more files can be placed in the folders.

In this embodiment, the privacy protection rule includes a locking rule, an unlocking rule, a freezing rule, and a unfreezing rule, and the privacy protection operation includes a locking operation unlocking operation, a freezing operation, and a unfreezing operation. The locking rule defines locking operation information of the target file in advance, for example, locking operation of a screen or locking by inputting a specific password, and the unlocking rule defines unlocking operation information of the target file in advance, for example, unlocking the screen, unlocking the password, unlocking a fingerprint, unlocking a face, and the like, and the unlocking can be performed by some special screen gestures, continuous key clicks, secret words (forms of voice recognition, question answering, and the like), multi-touch, continuous fingerprint clicks, and the like. The freezing rule defines the freezing operation information of the target file in advance, such as a specific fingerprint long-time pressing operation or inputting a specific password for locking, and the like, and the unfreezing rule defines the unfreezing operation information of the target file in advance, such as some special screen gestures, key continuous clicks, secret words (in the forms of voice recognition, question answering and the like), multi-point touch, fingerprint continuous clicks and the like.

In this embodiment, matching the operation information with the privacy protection rule of the target file includes:

acquiring the current privacy protection state of a target file;

when the current privacy protection state of the target file is a locked state, matching the operation information with the unlocking rule of the corresponding target file;

and when the current privacy protection state of the target file is an unlocking state, matching the operation information with the locking rule of the corresponding target file.

When the target file is in the locked state, the user cannot use and propagate the target file, the use refers to similar operations such as checking, copying and deleting the file, the propagation refers to similar operations such as sharing, uploading and downloading the file, and the user can input operation information to unlock the target file in the locked state. When the target file is in the unlocking state, the user can use and spread the target file, and in the unlocking state, the user can input operation information to lock. It can be understood that a file without predefined privacy protection rules is in neither an unlocked state nor a locked state, and is a non-target file.

For the collection that realizes operation information, the terminal can possess corresponding collection module, for example fingerprint module, camera module, touch module, button module etc. wherein, fingerprint module can be fingerprint module under the screen, and fingerprint module sets up in screen glass's below under the screen, mainly utilizes penetrating technologies such as ultrasonic wave, optics, can pierce through various different materials to gather the fingerprint information of screen top optional position department.

In another embodiment, the target file includes at least two associated files, that is, the target file and at least one other file have an association relationship therebetween, the files having the association relationship correspond to the same privacy protection rule, and the association relationship between the two associated files includes at least one of the following: the folder and a first file contained in the folder; a second file with which the file contains/references; files and their like; the file and the file corresponding to the file name contained in the file; and the user customizes the associated third file. Before the operation, the user may set a file association relationship corresponding to the target file, for example, set an association relationship between a folder and a subfile, an association relationship between a file and a file containing/referring, an association relationship between files of the same type, an association relationship between a file and a file corresponding to a file name contained in the file, or a file with a custom association.

And step 130, executing privacy protection operation of the target file according to the matching result.

In this embodiment, the privacy protection rule includes a locking rule and an unlocking rule, and when the privacy protection operation includes a locking operation and an unlocking operation, the privacy protection operation for the corresponding target file is executed according to a matching result, including:

when the operation information is matched with the locking rule, executing privacy protection operation for locking the corresponding target file;

and when the operation information is matched with the unlocking rule, executing privacy protection operation for unlocking the corresponding target file.

When the operation information input by the user is locking operation information, the terminal locks an unlocked target file, and otherwise, when the operation information input by the user is unlocking operation information, the terminal unlocks the locked target file. When the terminal has a plurality of target files, the same operation information can be matched with the privacy protection rules of one or more target files, and the execution objects of the privacy protection operation can be one or more according to the matching result of the operation information and the privacy protection rules. For example, a user sets a locking rule of a part or all of target files as screen locking, enters a privacy protection mode after pressing a power key to extinguish a screen and successfully lock the screen, the part or all of the target files are locked, exits from the privacy protection mode after the user sets an unlocking rule of the part or all of the target files as the same fingerprint unlocking, and unlocks the part or all of the target files after successfully identifying by using a specific fingerprint. For another example, if the user sets that both the locking rule and the unlocking rule of a certain target file are long-time fingerprint identification, the target file is unlocked by fingerprint identification when in the locked state, and the target file is locked by fingerprint identification when in the unlocked state.

In practical implementation, the privacy protection rule may not be limited to the locking rule and the unlocking rule, and may further include a usage rule, where the usage rule defines a usage right of the file in advance, and may, for example, enable viewing but disable editing and propagation, and the like, and when the received operation information does not match the usage rule, the privacy protection operation that does not respond to the operation information may be performed, for example, when the operation information of editing the target file is received, the privacy protection operation may not respond to the editing operation, and when the operation information of opening the target file is received, the target file is opened.

When the target file comprises at least two associated files, the privacy protection operation is executed on the at least two associated files simultaneously. Taking the encryption operation as an example, the file is encrypted, and the associated folder is also encrypted; the folder is encrypted, and the associated other subfile is also encrypted; the file is encrypted, and the file contained/referenced by the file is also encrypted, for example, the WORD contains the EXCEL table, and at the same time, the WORD is encrypted, and the relevant EXCEL table is also encrypted; files are encrypted, and associated like files are also encrypted, for example, if one bank application is encrypted, other bank applications of the same type are also encrypted, and if one game is encrypted, other like games are also encrypted; the file is encrypted, and the file corresponding to the file name contained in the file is also encrypted; the user sets the privacy-related files in advance, wherein one is encrypted, and the other is also encrypted.

The user can set the privacy protection rule for the file to be protected in advance. In this embodiment, the method for protecting privacy of a terminal further includes:

receiving setting information of a privacy protection rule;

and determining the target file according to the setting information and/or generating a corresponding privacy protection rule.

The privacy protection rule setting interface is, for example, an attribute interface of a file or a folder, and in the attribute interface, settings of a level, a type, and content of a lock are provided, for example, when an unlocking level of an unlocking rule selected by a user is high, a lock of a corresponding type is provided for the user to select, for example, a coded lock, a face recognition lock, and the like for setting specified type of coded content are provided, and after the user selects the type of the lock, the content of the lock, for example, the coded content, a face image, and the like, can be further set. When the locking rule and the unlocking rule are set, the locking grade of the locking rule and the unlocking grade of the unlocking rule can be prompted according to the privacy grade of the file, the higher the privacy grade of the file is, the higher the unlocking grade of the file is, the lower the locking grade of the file is, namely, the higher the privacy grade of the file is, the locking is easy to unlock, and therefore the file is prevented from being easily used and spread by other people.

After the privacy protection rule is set, the user can save the file by setting and confirming the operation, and the current file also becomes the target file. Through the privacy protection rule of setting specific files once, the user can open or close the privacy protection of a certain file through specific operation at any time and any place in the process of using the terminal, and the security is ensured and the convenience is provided at the same time.

The privacy protection method of the terminal receives the operation information, matches the operation information with the privacy protection rule of the target file, and executes privacy protection operation for the target file according to the matching result. Through the method, privacy protection can be performed on the files in the terminal in a targeted manner, the target files can be specifically prevented from being illegally acquired by other users, the protection has extremely strong pertinence, and the problem that single protection cannot be performed in the traditional locking process or a single file cannot be covered even if single protection is performed is solved. Moreover, the method and the device can ensure the safety and simultaneously have convenience, and improve the user experience through a simple, convenient and quick interactive process.

For example, a user sets a locking rule of a part or all of target files as screen locking, enters a privacy protection mode after pressing a power key to extinguish a screen and successfully lock the screen, the part or all of the target files are locked, exits from the privacy protection mode after the user sets an unlocking rule of the part or all of the target files as the same fingerprint unlocking, and unlocks the part or all of the target files after successfully identifying by using a specific fingerprint. By the mode, a user can operate one target file independently or in batches, unlocking can be performed before or during file use, and convenience is greatly improved.

The user can set the privacy protection rule for the file to be protected in advance. In this embodiment, the method for protecting privacy of a terminal further includes:

receiving setting information of a privacy protection rule;

and determining the target file according to the setting information and/or generating a corresponding privacy protection rule.

The privacy protection rule setting interface is, for example, an attribute interface of a file or a folder, and in the attribute interface, settings of a level, a type, and content of a lock are provided, for example, when an unlocking level of an unlocking rule selected by a user is high, a lock of a corresponding type is provided for the user to select, for example, a coded lock, a face recognition lock, and the like for setting specified type of coded content are provided, and after the user selects the type of the lock, the content of the lock, for example, the coded content, a face image, and the like, can be further set. When the locking rule and the unlocking rule are set, the locking grade of the locking rule and the unlocking grade of the unlocking rule can be prompted according to the privacy grade of the file, the higher the privacy grade of the file is, the higher the unlocking grade of the file is, the lower the locking grade of the file is, namely, the higher the privacy grade of the file is, the locking is easy to unlock, and therefore the file is prevented from being easily used and spread by other people.

The privacy protection method of the terminal receives the operation information, matches the operation information with the privacy protection rule of a target file if the operation information is directed to the target file, otherwise matches the operation information with the privacy protection rules of all the target files, and finally executes the privacy protection operation directed to the corresponding target file according to the matching result. Through the mode, privacy protection can be carried out on the file in the terminal in a targeted manner, convenience can be achieved while safety is guaranteed, and user experience is improved through a simple, convenient and quick interaction process.

step 350, judging whether the operation is the operation of opening the target file; if yes, go to step 360; otherwise, returning to step 310;

step 360, judging whether the operation information is received again within a preset time length; if yes, go to step 370; otherwise, returning to step 310;

step 370, matching the operation information received again with the unlocking rule of the corresponding target file;

step 380, judging whether matching is performed; if yes, go to step 390; otherwise, returning to step 310;

step 390, perform a privacy protection operation to unlock the corresponding target file.

In step 310, the operation information is information generated when the terminal receives a user operation, such as an operation signal of pressing an entity key, a signal of clicking an interface, password information included when a password is input, fingerprint information included when a fingerprint is input, a face image included when a face is recognized, and the like.

Steps 320 to 380 are used to implement the process of matching the operation information with the privacy protection rule of the target file.

In step 350, when the operation information does not match the unlocking rule, it is further determined whether the operation information is an operation of opening the target file, for example, when the user clicks the file, the operation information is an operation of opening the target file, otherwise, the operation information is not an operation of opening the target file.

In step 360, when the operation information is an operation of opening the target file, a verification period of a preset duration is reserved, for example, 5 seconds, and it is determined whether the operation information is received again within the preset duration.

In step 370, if the operation information is received again within the preset duration, matching the operation information received again with the unlocking rule of the corresponding target file, and unlocking the corresponding target file if the matching is consistent.
