Embodiment 1

An embodiment of the present invention provides an information protection method. As shown in FIG. 1, the method may include:

S101. When unlocking, the mobile terminal collects current user feature information.

In the embodiment of the present invention, when a user triggers an unlocking case on the mobile terminal to unlock, the mobile terminal starts a feature information collecting module on the mobile terminal, and collects feature information of the current user, that is, collects current user feature information.

Specifically, when unlocking, the mobile terminal can perform current user feature information collection work within a certain time. The user feature information in the embodiment of the present invention may be the user face information, or may be a unique biometric feature of the user, such as the user fingerprint information, and the user feature information of the solution may be implemented in the embodiment of the present invention. .

It should be noted that the unlocking manner may be the trigger button unlocking or other unlocking manner, and the invention is not limited.

In the embodiment of the present invention, the foregoing certain time may be 5 seconds, and the specific time may be determined according to an actual situation, which is not limited by the embodiment of the present invention.

For example, the implementation of the feature information collection module is that the face information of the current user can be collected by the camera on the mobile terminal, and the face information of the current user may include the facial features of the current user.

Specifically, in order to facilitate the user's use, in the case of a front camera, the mobile terminal The front camera is used to collect the current user feature information; without the front camera, the mobile terminal can activate the rear camera to collect current user feature information.

It should be noted that, in the embodiment of the present invention, before the unlocking button is triggered, before the mobile terminal collects the current user feature information, the mobile terminal needs to collect user feature information corresponding to the user right, and extracts the user feature information from the user feature information. The feature data of the feature information generates preset feature data and is stored in the feature information storage module.

In the embodiment of the present invention, when the user feature information is the face information, the face information is information indicating the face feature acquired by the camera of the mobile terminal to capture the face photo, and the mobile face feature is filtered to eliminate the influence of the photo resolution on the face information authentication. When the terminal has two cameras, two cameras can be used to obtain a user face information respectively, so that each user can correspond to the preset feature data with the same number of cameras, so that any subsequent face information authentication can be used. A user's face feature of a camera and extracting feature data of the face feature.

In the embodiment of the present invention, the mobile terminal may establish a preset feature data information library to manage preset feature data, where the preset feature data includes feature data corresponding to the feature information of the advanced guest user and the manager.

In the embodiment of the present invention, user rights corresponding to different users may be set in the mobile terminal. In order to better protect the user privacy of the mobile terminal owner, it is necessary to set the level of the user authority corresponding to different users in advance. For example, the administrator's user privilege level is 0; the advanced guest user's user privilege level is set to 1; the normal guest user's user privilege is 2. The specific user privilege level setting may be determined according to the actual administrator setting, which is not limited in the embodiment of the present invention.

S102. When the current terminal collects current user feature information, the mobile terminal extracts feature data of the current user feature information.

When the mobile terminal collects the current user feature information, the mobile terminal extracts the position ratio of each feature point of the current user feature, such as the eyes, the nose, the eyebrow, and the current user feature information. The position ratio of organs such as chin.

It can be understood that, in the embodiment of the present invention, since the feature data extracted in the user feature information is a user with the same or similar features, the possibility is small. Therefore, the user characteristic information is not easily stolen and the confidentiality is good.

Illustratively, the user A's smartphone collects the face information of the user B who is using the smart phone, and extracts the location ratio data packet M of the user B's eyes, nose, eyebrows, and chin.

S103. The mobile terminal compares the feature data with the preset feature data to determine a current user right.

It should be noted that the current user rights in the embodiment of the present invention include guest rights and administrator rights; wherein the guest rights also include normal guest rights and advanced guest rights.

When the mobile terminal collects the current user feature information, and extracts the feature data of the current user feature information, the mobile terminal compares the feature data with the preset feature data to determine whether the feature data of the current user and the feature information collected by the mobile terminal are The preset feature data in the feature data information store stored by the storage module is consistent, thereby determining the current user rights.

It should be noted that, in the embodiment of the present invention, the owner of the mobile terminal, as a manager, can perform maintenance, update, and the like on the user rights and information in the preset feature data information base. The administrator can set his own user authority to the administrator authority level, and the manager authority corresponds to the feature data of the manager's feature information, and will allow the user to view the private user information data in the mobile terminal (friend, The user rights of the relatives, etc. are set to the advanced guest rights, which correspond to the feature data of the feature information of the advanced guest user. Managers will be themselves The feature data of the feature information and the feature data of the feature information of the advanced visitor are stored as preset feature data in the feature information storage module of the mobile terminal.

In the embodiment of the present invention, the authority of the user who does not have the feature data stored in the mobile terminal in advance is set to the normal guest authority level.

In the embodiment of the present invention, the ordinary guest authority: the ordinary guest user can use the general functions of the mobile terminal (such as making a call, sending a text message, etc.), but does not support the access operation of the private information (user information data) in the mobile terminal. .

Advanced Guest Permissions: Advanced guest users can use the general functions of the mobile terminal normally, and also support access to the private information already in the mobile terminal.

Manager authority: The administrator can use the common functions of the mobile terminal, and also support the access operation of the private information in the mobile terminal. At the same time, it supports the management and maintenance of the private information, and supports the maintenance and management of the user information of the advanced visitor. .

In the embodiment of the present invention, after determining the current user right, the mobile terminal stores the current user permission value (the current user permission level) in the current user rights storage unit of the mobile terminal.

Illustratively, after the user A's smartphone collects the face information of the user B who is using the smart phone, and extracts the location ratio data packet M of the user B's eyes, nose, eyebrows, and chin, the The smartphone compares M with the position ratio packet N of the preset administrator's eyes, nose, eyebrows, and chin, and M and N do not match. Therefore, the eyes and nose of the smartphone and the advanced visitor user are The position ratio of the eyebrows and the chin is proportional to the data package K. M and K are inconsistent. Therefore, user B is neither a manager nor an advanced guest user, but an ordinary guest user, that is, the smartphone determines that user B's user authority is normal. Guest permissions.

S104. The mobile terminal determines, according to the current user right, whether to update the user information data in the preset application to switch to the current user mode.

It should be noted that the current user mode includes: a guest mode and a management mode; Guest mode also includes: normal guest mode and advanced guest mode. The administrator user corresponds to the administrator authority, and the manager can perform various operations of the mobile terminal in the management mode, and the advanced guest user corresponds to the advanced guest permission, and the advanced guest user performs various operations of the mobile terminal in the advanced guest mode, and the ordinary guest user corresponds to Ordinary guest authority, the ordinary guest user performs various operations of the mobile terminal in the normal guest mode.

In the embodiment of the present invention, the management mode supports management and maintenance of user information data, and management and maintenance of user group information corresponding to advanced guest rights.

Specifically, in the normal guest mode, the ordinary guest user can use the general functions of the mobile terminal (eg, making a call, sending a text message, etc.), but does not support the access operation of the private information (user information data) already in the mobile terminal.

In the advanced guest mode, the advanced guest user can normally use the general functions of the mobile terminal, and also supports the access operation of the private information in the mobile terminal.

In the management mode, the administrator can use the common functions of the mobile terminal, and also support the access operation of the private information in the mobile terminal, and support the management and maintenance of the private information, and support the maintenance of the user group information of the advanced visitor. management.

In the embodiment of the present invention, the mobile terminal compares the feature data with the preset feature data, and after determining the current user right, the mobile terminal enters a user mode corresponding to the current user right according to the current user right, so that the current user can only Perform the operation corresponding to your own permissions.

Specifically, the mobile terminal performs the handover to the current user mode corresponding to the current user right by determining whether to update the user information data in the preset application according to the current user authority, where the user information data in the embodiment of the present invention is the user's Private information.

It should be noted that, in the embodiment of the present invention, the mobile terminal preset application is set to a different mode, an ordinary guest mode, an advanced guest mode, and a management mode. The above-mentioned preset applications are mainly applications that support access to the user's private information (account information, photos, videos, etc.).

In the embodiment of the present invention, a preset application that can access user private information may be used for chat soft. Information, file management and library.

In the embodiment of the present invention, the mobile terminal can implement switching of different user modes of the preset application by whether the data needs to be re-initialized for the preset application, that is, the user information data in the preset application is updated. The specific implementation process will be described in detail in the subsequent embodiments.

In the embodiment of the present invention, after entering the current user mode, the mobile terminal may also log out the current user mode by using a lock screen operation, and clear the mode information of the access. When the administrator needs to switch the usage mode or other users request to use the mobile terminal, in order to protect the privacy, the current user's access mode can be cancelled by the lock screen operation, the unfamiliar current user triggers the unlocking, the mobile terminal starts the camera, collects the current user feature information, and extracts The feature data, because the preset feature data of the user is not set in the mobile terminal, the current user identity is verified as a normal guest user, and after the unlocking, the current user enters the normal guest mode. Such a user switching method only enters the desktop on the surface, and actually enters the usage mode, which is determined by the feature data. For example, when a friend borrows a mobile terminal, or when a party is threatened, it can implicitly enter a predetermined user mode to protect the security of his user information data.

It can be understood that the mobile terminal can obtain the user mode of the preset application corresponding to the feature data by acquiring the feature data of the feature information, so that the operation of the same mobile terminal by different users is more convenient, and the unlocking operation is simplified.

The embodiment of the present invention provides an information protection method and a mobile terminal. When the mobile terminal unlocks, the current user feature information is collected. When the current user feature information is collected, the feature data of the current user feature information is extracted; The feature data is compared to determine the current user rights; according to the current user rights, it is determined whether to update the user information data in the preset application to switch to the current user mode. According to the technical implementation of the present invention, since the mobile terminal can acquire the feature data of the user feature information when the unlocking is triggered, even if different users use the same mobile terminal, the entry can only correspond to the user feature data. Applying in the user mode of the preset application, so that the unallowed user cannot view the shift The user information data in the mobile terminal further improves the information security in the mobile terminal and improves the user experience.

Embodiment 2

An embodiment of the present invention provides an information protection method. As shown in FIG. 2, the method may include:

S201. When unlocking, the mobile terminal collects current user feature information.

Specifically, when the unlock button is triggered, the mobile terminal can perform the collection of the current user feature information within a certain time. The user feature information in the embodiment of the present invention may be the user's face information, or may be a unique feature of the user, such as the user's fingerprint information, and the user feature information of the present invention may be implemented.

Specifically, in order to facilitate user use, in the case of a front camera, the mobile terminal activates the front camera to perform current user feature information collection; without the front camera, the mobile terminal can activate the rear camera to collect Current user feature information.

In the embodiment of the present invention, user rights corresponding to different users may be set in the mobile terminal. In order to better protect the user privacy of the mobile terminal owner, it is necessary to set the level of the user authority corresponding to different users in advance.

S202. When the current terminal collects current user feature information, the mobile terminal extracts feature data of the current user feature information.

It can be understood that, in the embodiment of the present invention, the feature extracted from the user feature information The likelihood that the data is a user with the same or similar characteristics is small. Therefore, the user characteristic information is not easily stolen and the confidentiality is good.

S203. The mobile terminal compares the feature data with the preset feature data to determine a current user right.

It should be noted that, in the embodiment of the present invention, the owner of the mobile terminal, as a manager, can perform maintenance, update, and the like on the user rights and information in the preset feature data information base. The administrator can set his own user authority to the administrator authority level, and the manager authority corresponds to the feature data of the manager's feature information, and will allow the user to view the private user information data in the mobile terminal (friend, The user rights of the relatives, etc. are set to the advanced guest rights, which correspond to the feature data of the feature information of the advanced guest user. The administrator stores the feature data of the own feature information and the feature data of the feature information of the advanced visitor as preset feature data in the feature information storage module of the mobile terminal.

In the embodiment of the present invention, the ordinary guest authority: the ordinary guest user can use the general functions of the mobile terminal (such as making a call, sending a text message, etc.), but does not support the private information already in the mobile terminal. Access operation (user information data).

In the embodiment of the present invention, after determining the current user right, the mobile terminal stores the current user permission value (the current user authority level) in the user right storage unit of the mobile terminal.

S204. The mobile terminal determines whether the current user right is consistent with the previous user right.

In the embodiment of the present invention, the mobile terminal can implement switching of different user modes of the preset application by whether to re-initialize the data to the preset application, that is, update the user information data (private information of the user) in the preset application.

It should be noted that, when the user does not use the mobile terminal for the first time, after the mobile terminal compares the feature data with the preset feature data to determine the current user right, the mobile terminal determines that the current user right is stored in the user right storage unit. Whether the previous user rights in the middle are consistent.

Specifically, it is stored in the user authority storage unit as a level of user authority. For example, management The user privilege level is 0; the advanced guest user's privilege level is set to 1; the normal guest user's privilege level is 2. The specific user privilege level setting may be determined according to the actual administrator setting, which is not limited in the embodiment of the present invention.

It should be noted that, after the mobile terminal determines the user right once, the user authority value (the current user authority level) is stored in the user authority storage unit of the mobile terminal. Therefore, when the mobile terminal determines the current user right, the user right storage unit in the mobile terminal stores the user right of the previous user. Therefore, the mobile terminal needs to determine whether the current user right is consistent with the previous user right, so as to determine whether to update the preset application.

In the embodiment of the present invention, when the user uses the mobile terminal for the first time, since the mobile terminal does not have the previous user right, the mobile terminal does not perform this step, and the mobile terminal directly updates the user information in the preset application according to the current user right. The data is fine.

S205: When the current user right is consistent with the previous user right, the mobile terminal determines not to update the user information data in the preset application.

After the mobile terminal determines whether the current user right is consistent with the previous user right, when the current user right is consistent with the previous user right, the current user right is the same as the previous user right, and the mobile terminal determines that the preset may not be updated. User information data in the application, that is, the current user uses the same preset application settings as the previous user.

In the embodiment of the present invention, the preset application that can access the user's private information may be chat software information, file management, and library.

It can be understood that, when the current user right is consistent with the previous user right, the mobile terminal determines that the user information data in the preset application is not updated, thereby effectively preventing the mobile terminal from updating the preset application every time the mobile terminal is unlocked. Therefore, the use efficiency of the mobile terminal is improved, and unnecessary operation progress is reduced.

S206: When the current user right is inconsistent with the previous user right, the mobile terminal updates the user information data in the preset application according to the current user right.

In the embodiment of the present invention, after the mobile terminal determines whether the current user right is consistent with the previous user right, and the current user right is inconsistent with the previous user right, the mobile terminal enters the user corresponding to the current user right according to the current user right. Mode, so that the current user can only perform operations corresponding to their own permissions.

It should be noted that the current user mode includes: a guest mode and a management mode; wherein the guest mode further includes: a normal guest mode and an advanced guest mode. The administrator user corresponds to the administrator authority, and the manager can perform various operations of the mobile terminal in the management mode, and the advanced guest user corresponds to the advanced guest permission, and the advanced guest user performs various operations of the mobile terminal in the advanced guest mode, and the ordinary guest user corresponds to Ordinary guest authority, the ordinary guest user performs various operations of the mobile terminal in the normal guest mode.

Specifically, when the current user right is the normal guest permission, it is determined that the user information data is not loaded to the preset application, and the guest mode is entered.

When the current user right is the advanced guest permission, it is determined that the user information data is loaded for the preset application, and the advanced guest mode is entered.

When the current user right is the administrator authority, it is determined that the user information data is loaded on the preset application, and the management mode is entered.

In the embodiment of the present invention, the management mode supports management and maintenance of user information data, and management and maintenance of user group information corresponding to advanced guest rights. The management mode supports the addition and deletion of administrators and members of the advanced guest user group; and the maintenance and maintenance of the member information of the manager and the advanced guest user group.

Specifically, in the normal guest mode, the ordinary guest user can use the general functions of the mobile terminal (eg, making a call, sending a text message, etc.), but does not support the private information already in the mobile terminal (using User information data) access operation.

It should be noted that, in the embodiment of the present invention, the mobile terminal preset application is set to a different mode, an ordinary guest mode, an advanced guest mode, and a management mode. The above-mentioned preset applications are mainly applications that support access to the user's private information (account information, photos, videos, etc.). When a normal visitor uses a mobile terminal, the ordinary visitor is not allowed to access the private information of the user, and the mobile terminal updates (initializes) the private information (user information data) in the preset application, and stores the private information in the private information storage unit. The private information storage unit is not accessible to ordinary visitors.

It can be understood that the mobile terminal can obtain the user mode of the preset application corresponding to the feature data by acquiring feature data of the feature information, so that different users use the same mobile terminal. The operation of the end is more convenient and the unlocking operation is simplified.

It can be understood that, because the current user right is inconsistent with the previous user right, the mobile terminal updates the user information data in the preset application according to the current user right, so that it is possible to effectively avoid re-initializing each time the mobile terminal is unlocked. User information data in the preset application; in addition, since the user mode switching does not involve the entire system of the mobile terminal, only the user information data needs to be updated for some preset applications, thereby improving the response efficiency of the mobile terminal.

It should be noted that S205 and S206 are optional steps after S204, and one step is selected according to the actual detection situation; that is, in the embodiment of the present invention, after S204, S205 may be performed, or S206 may be executed.
