detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

Embodiment one

An embodiment of the present invention provides an information protection method, as shown in Figure 1, the method may include:

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

In the embodiment of the present invention, when a user triggers the unlocking case on the mobile terminal to unlock, the mobile terminal starts the characteristic information collection module on the mobile terminal to collect characteristic information of the current user, that is, collect characteristic information of the current user.

Specifically, when unlocked, the mobile terminal can collect current user characteristic information within a certain period of time. Among them, the user characteristic information in the embodiment of the present invention may be the user's face information, and may also be the user's unique biological characteristics such as user fingerprint information. Specifically, the user characteristic information that can realize this solution is not limited in the embodiment of the present invention. .

It should be noted that the unlocking method may be unlocking by triggering a button, or other unlocking methods, which are not limited in the present invention.

Optionally, the above-mentioned certain time may be 5 seconds, and the specific time may be determined according to actual conditions, which is not limited in this embodiment of the present invention.

For example, an implementation form of the characteristic information collection module is to collect the current user's face information through the camera on the mobile terminal, and the current user's face information may include the current user's facial features.

Specifically, for the convenience of users, when there is a front-facing camera, the mobile terminal starts the front-facing camera to collect current user characteristic information; when there is no front-facing camera, the mobile terminal can start the rear-facing camera to collect Current user profile information.

It should be noted that, in the embodiment of the present invention, when the unlock button is triggered, before the mobile terminal collects the current user characteristic information, the mobile terminal needs to collect the user characteristic information corresponding to the user authority, and extract the user characteristic information from the user characteristic information. The feature data of the feature information is to generate preset feature data and store it in the feature information storage module.

Optionally, when the user characteristic information is face information, the face information is the information representing the face characteristics obtained by the camera of the mobile terminal to capture the face photos. In order to eliminate the influence of the photo resolution on the face information authentication, the mobile terminal has In the case of two cameras, the two cameras can be used to obtain the face information of a user respectively. In this way, each user can correspond to the same preset feature data as the number of cameras, which is convenient for using any camera for subsequent face information authentication. The user's facial features and extract the feature data of the facial features.

It should be noted that the mobile terminal in the embodiment of the present invention may be a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a personal digital assistant, a tablet computer, a portable multimedia player, a navigation device, etc., and a mobile terminal such as Stationary terminal for digital TV, desktop computer, etc. However, those skilled in the art will understand that the configuration according to the embodiments of the present invention can also be applied to stationary type terminals, in addition to elements specifically used for mobile purposes.

Further, the mobile terminal may establish a preset feature data information database to manage preset feature data, and the preset feature data includes feature data corresponding to feature information of senior guest users and managers.

Further, user permissions 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 pre-set the levels of user rights corresponding to different users. For example, the user authority level of the administrator is set to 0; the user authority level of the advanced guest user is set to 1; the user authority level of the ordinary guest user is set to 2. The specific user authority 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 mobile terminal collects the characteristic information of the current user, extract characteristic data of the characteristic information of the current user.

When unlocking, after the mobile terminal collects the characteristic information of the current user, when the mobile terminal collects the characteristic information of the current user, it extracts the position ratio of each characteristic point of the characteristic of the current user from the characteristic information of the current user, such as eyes, nose, eyebrows and The proportion of the position of the jaw and other organs.

It can be understood that, in the embodiment of the present invention, since the characteristic data extracted from the user characteristic information is unlikely to be a user with the same or similar characteristics. Therefore, the use of user characteristic information is not easy to be stolen, and the confidentiality is good.

Exemplarily, the smart phone of user A collects the face information of user B who is using the smart phone, and extracts the position ratio data package M of user B's eyes, nose, eyebrows, chin and other organs.

S103. The mobile terminal compares the characteristic data with the preset characteristic data to determine the current user authority.

It should be noted that the current user authority in the embodiment of the present invention includes visitor authority and manager authority; wherein, visitor authority also includes common visitor authority and advanced visitor authority.

When the mobile terminal collects the characteristic information of the current user, after extracting the characteristic data of the characteristic information of the current user, the mobile terminal compares the characteristic data with the preset characteristic data to determine whether the characteristic data of the current user collected by the mobile terminal is consistent with the characteristic information The preset characteristic data in the characteristic data information database stored by the storage module are consistent, so as to determine the current user authority.

It should be noted that, in the embodiment of the present invention, the owner of the mobile terminal acts as a manager, and can maintain, update, and manage user rights and information in the preset feature data database. The manager can set his user authority as the manager authority level, and the manager authority corresponds to the feature data of the manager's feature information, and will allow users (friends, friends, relatives, etc.) is set as an advanced visitor authority, and the advanced visitor authority corresponds to the characteristic data of the characteristic information of the advanced visitor user. The manager stores the feature data of his own feature information and the feature data of the senior visitor's feature information as preset feature data in the feature information storage module of the mobile terminal.

Further, in the embodiment of the present invention, the permissions of users whose feature data is not pre-stored in the mobile terminal are all set to the normal visitor permission level.

Optionally, ordinary guest authority: ordinary guest users can use the general functions of the mobile terminal (such as making calls, sending text messages, etc.), but do not support access to existing private information (user information data) in the mobile terminal.

Advanced guest rights: Advanced guest users can not only use the general functions of the mobile terminal, but also support access to private information in the mobile terminal.

Administrator rights: administrators can use the general functions of the mobile terminal, and also support the access operation of the existing private information in the mobile terminal, and support the management and maintenance of private information, and support the maintenance and management of user group information of advanced visitors .

Further, after determining the current user authority, the mobile terminal stores the current user authority value (current user authority level) in the current user authority storage unit of the mobile terminal.

Exemplarily, after user A's smart phone collects the face information of user B who is using the smart phone, and extracts the position ratio data package M of user B's eyes, nose, eyebrows, chin and other organs, the The smart phone compares M with the stored preset data packet N of the positions and proportions of the administrator's eyes, nose, eyebrows, and chin, and M is inconsistent with N. Comparing the location ratio data packet K of eyebrows and chin and other organs, M and K are inconsistent. Therefore, user B is neither an administrator nor an advanced guest user, but an ordinary guest user, that is, the smartphone determines that the user authority of user B is ordinary Guest permissions.

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

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

Optionally, the management mode supports the management and maintenance of user information data, and the management and maintenance of user group information corresponding to advanced visitor rights.

Specifically, in the ordinary visitor mode, the ordinary visitor 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 to the existing private information (user information data) in the mobile terminal.

In the advanced guest mode, the advanced guest user can not only use the common functions of the mobile terminal normally, but also support the access operation to the existing private information in the mobile terminal.

In the management mode, the administrator can use the general functions of the mobile terminal, and also supports the access operation of the existing private information in the mobile terminal, and supports the management and maintenance of the private information, and supports the maintenance and maintenance of the user group information of senior visitors. manage.

In the embodiment of the present invention, the mobile terminal compares the characteristic data with the preset characteristic data, and after determining the current user authority, the mobile terminal enters the user mode corresponding to the current user authority according to the current user authority, so that the current user can only Perform operations corresponding to your permissions.

Specifically, the mobile terminal switches to the current user mode corresponding to the current user authority by determining whether to update the user information data in the preset application according to the current user authority, wherein 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 default application of the mobile terminal is set to different modes, namely a normal visitor mode, an advanced visitor mode and a management mode. The aforementioned default applications are mainly applications that support access to the user's private information (account information, photos, videos, and other information).

Optionally, the embodiment of the present invention involves preset applications that can access the user's private information, such as chat software information, file management, and gallery.

In the embodiment of the present invention, the mobile terminal can switch between different user modes of the preset application according to whether it needs to re-initialize the data of the preset application, that is, update the user information data in the preset application. The specific implementation process will be described in detail in subsequent embodiments.

Further, in the embodiment of the present invention, after entering the current user mode, the mobile terminal can also log out of the current user mode through a screen lock operation, and clear its own access mode information. When the administrator needs to switch the usage mode or other users request to use the mobile terminal, in order to protect privacy, the current user’s access mode can be canceled through the lock screen operation, and the unfamiliar current user triggers the unlock, and the mobile terminal starts the camera to collect the current user’s characteristic information and extract Feature data, because the mobile terminal does not set the preset feature data of the user, therefore, the current user identity verification is a common visitor user, so, after unlocking, the current user enters the common visitor mode. Such a user switching method only enters the desktop on the surface, and actually enters the use mode, which is determined by the feature data. For example, when a friend borrows a mobile terminal, or when a party is threatened, they can covertly enter a pre-determined user mode to protect the security of their own user information and data.

It can be understood that the mobile terminal can enter the user mode of the preset application corresponding to the characteristic data by acquiring the characteristic data of the characteristic information, which makes it more convenient for different users to use the same mobile terminal, and at the same time simplifies the unlocking operation.

An embodiment of the present invention provides an information protection method and a mobile terminal. When the mobile terminal is unlocked, it collects characteristic information of the current user; when the characteristic information of the current user is collected, it extracts characteristic data of the characteristic information of the current user; The feature data is compared to determine the current user authority; according to the current user authority, it is determined whether to update the user information data in the preset application to switch to the current user mode. By adopting the technical implementation scheme of the present invention, since the mobile terminal can obtain the feature data of the user feature information when the unlocking is triggered, even if different users use the same mobile terminal, they can only access the mobile terminal in the corresponding user feature data. Application operations are performed in the user mode of the preset application, so that unauthorized users cannot view user information data in the mobile terminal, thereby improving information security in the mobile terminal and improving user experience.

Further, the mobile terminal may establish a preset feature data information database to manage preset feature data, and the preset feature data includes feature data corresponding to feature information of senior guest users and managers.

Further, user permissions 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 pre-set the levels of user rights corresponding to different users.

S202. When the mobile terminal collects the characteristic information of the current user, extract characteristic data of the characteristic information of the current user.

When unlocking, after the mobile terminal collects the characteristic information of the current user, when the mobile terminal collects the characteristic information of the current user, it extracts the position ratio of each characteristic point of the characteristic of the current user from the characteristic information of the current user, such as eyes, nose, eyebrows and The proportion of the position of the jaw and other organs.

It can be understood that, in the embodiment of the present invention, since the characteristic data extracted from the user characteristic information is unlikely to be a user with the same or similar characteristics. Therefore, the use of user characteristic information is not easy to be stolen, and the confidentiality is good.

Exemplarily, the smart phone of user A collects the face information of user B who is using the smart phone, and extracts the position ratio data package M of user B's eyes, nose, eyebrows, chin and other organs.

S203. The mobile terminal compares the characteristic data with the preset characteristic data to determine the current user authority.

It should be noted that the current user authority in the embodiment of the present invention includes visitor authority and manager authority; wherein, visitor authority also includes common visitor authority and advanced visitor authority.

When the mobile terminal collects the characteristic information of the current user, after extracting the characteristic data of the characteristic information of the current user, the mobile terminal compares the characteristic data with the preset characteristic data to determine whether the characteristic data of the current user collected by the mobile terminal is consistent with the characteristic information The preset characteristic data in the characteristic data information database stored by the storage module are consistent, so as to determine the current user authority.

It should be noted that, in the embodiment of the present invention, the owner of the mobile terminal acts as a manager, and can maintain, update, and manage user rights and information in the preset feature data database. The manager can set his user authority as the manager authority level, and the manager authority corresponds to the feature data of the manager's feature information, and will allow users (friends, friends, relatives, etc.) is set as an advanced visitor authority, and the advanced visitor authority corresponds to the characteristic data of the characteristic information of the advanced visitor user. The manager stores the feature data of his own feature information and the feature data of the senior visitor's feature information as preset feature data in the feature information storage module of the mobile terminal.

Further, in the embodiment of the present invention, the permissions of users whose feature data is not pre-stored in the mobile terminal are all set to the normal visitor permission level.

Optionally, ordinary guest authority: ordinary guest users can use the general functions of the mobile terminal (such as making calls, sending text messages, etc.), but do not support access to existing private information (user information data) in the mobile terminal.

Advanced guest rights: Advanced guest users can not only use the general functions of the mobile terminal, but also support access to private information in the mobile terminal.

Administrator rights: administrators can use the general functions of the mobile terminal, and also support the access operation of the existing private information in the mobile terminal, and support the management and maintenance of private information, and support the maintenance and management of user group information of advanced visitors .

Further, after determining the current user authority, the mobile terminal stores the current user authority value (current user authority level) in the user authority storage unit of the mobile terminal.

Exemplarily, after user A's smart phone collects the face information of user B who is using the smart phone, and extracts the position ratio data package M of user B's eyes, nose, eyebrows, chin and other organs, the The smart phone compares M with the stored preset data packet N of the positions and proportions of the administrator's eyes, nose, eyebrows, and chin, and M is inconsistent with N. Comparing the location ratio data packet K of eyebrows and chin and other organs, M and K are inconsistent. Therefore, user B is neither an administrator nor an advanced guest user, but an ordinary guest user, that is, the smartphone determines that the user authority of user B is ordinary Guest permissions.

S204. The mobile terminal judges whether the current user authority is consistent with the previous user authority.

In the embodiment of the present invention, the mobile terminal can switch between different user modes of the preset application according to whether it needs to re-initialize the data of 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 is not using 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 authority, the mobile terminal judges the current user authority and the value stored in the user authority storage unit. Check whether the previous user permissions in the system are consistent.

Specifically, what is stored in the user authority storage unit is the level of user authority. For example, the user authority level of the administrator is set to 0; the user authority level of the advanced guest user is set to 1; the user authority level of the ordinary guest user is set to 2. The specific user authority 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 determining the user authority once, the mobile terminal stores the user authority value (current user authority level) in the user authority storage unit of the mobile terminal each time. Therefore, when the mobile terminal determines the current user authority, the user authority of the previous user is stored in the user authority storage unit in the mobile terminal. Therefore, the mobile terminal needs to determine whether the current user authority is consistent with the previous user authority, so as to determine whether to update the preset application.

Further, when the user uses the mobile terminal for the first time, since there is no previous user authority in the mobile terminal, this step does not need to be performed, and the mobile terminal can directly update the user information data in the preset application according to the current user authority .

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

After the mobile terminal judges whether the current user authority is consistent with the previous user authority, when the current user authority is consistent with the previous user authority, it indicates that the current user authority is the same as the previous user authority, so the mobile terminal determines that it is not necessary to update the preset User information data in the application, that is, the current user uses the same preset application settings as the previous user.

Optionally, the embodiment of the present invention involves preset applications that can access the user's private information, such as chat software information, file management, and gallery.

It can be understood that when the current user authority is consistent with the previous user authority, the mobile terminal determines not to update the user information data in the preset application, which effectively avoids updating the preset application every time the mobile terminal is unlocked. Therefore, the use efficiency of the mobile terminal is improved, and unnecessary operation processes are reduced.

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

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

Specifically, the mobile terminal switches to the current user mode corresponding to the current user authority by determining whether to update the user information data in the preset application according to the current user authority, wherein the user information data in the embodiment of the present invention is the user's private information.

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

Specifically, when the current user authority is a normal visitor authority, it is determined not to load user information data to the preset application and enter the guest mode.

When the current user authority is the advanced visitor authority, it is determined to load the user information data to the preset application and enter the advanced visitor mode.

When the current user authority is the administrator authority, it is determined to load the user information data to the preset application and enter the management mode.

Optionally, the management mode supports the management and maintenance of user information data, and the management and maintenance of user group information corresponding to advanced visitor rights. The management mode supports the addition and deletion of managers and senior guest user group members; and the update and maintenance of manager and senior guest user group member characteristic information.

Specifically, in the ordinary visitor mode, the ordinary visitor 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 to the existing private information (user information data) in the mobile terminal.

In the advanced guest mode, the advanced guest user can not only use the common functions of the mobile terminal normally, but also support the access operation to the existing private information in the mobile terminal.

In the management mode, the administrator can use the general functions of the mobile terminal, and also supports the access operation of the existing private information in the mobile terminal, and supports the management and maintenance of the private information, and supports the maintenance and maintenance of the user group information of senior visitors. manage.

It should be noted that, in the embodiment of the present invention, the default application of the mobile terminal is set to different modes, namely a normal visitor mode, an advanced visitor mode and a management mode. The aforementioned default applications are mainly applications that support access to the user's private information (account information, photos, videos, and other information). When ordinary visitors use the mobile terminal, ordinary visitors are not allowed to access the user's private information, the mobile terminal updates (initializes) the private information (user information data) in the preset application, stores the private information in the private information storage unit, The private information storage unit cannot be accessed by ordinary visitors.

Further, in the embodiment of the present invention, after entering the current user mode, the mobile terminal can also log out of the current user mode through a screen lock operation, and clear its own access mode information. When the administrator needs to switch the usage mode or other users request to use the mobile terminal, in order to protect privacy, the current user’s access mode can be canceled through the lock screen operation, and the unfamiliar current user triggers the unlock, and the mobile terminal starts the camera to collect the current user’s characteristic information and extract Feature data, because the mobile terminal does not set the preset feature data of the user, therefore, the current user identity verification is a common visitor user, so, after unlocking, the current user enters the common visitor mode. Such a user switching method only enters the desktop on the surface, and actually enters the use mode, which is determined by the characteristic data. For example, when a friend borrows a mobile terminal, or when a party is threatened, they can covertly enter a pre-determined user mode to protect the security of their own user information and data.

It can be understood that the mobile terminal can enter the user mode of the preset application corresponding to the characteristic data by acquiring the characteristic data of the characteristic information, which makes it more convenient for different users to use the same mobile terminal, and at the same time simplifies the unlocking operation.

It can be understood that when the current user authority is inconsistent with the previous user authority, the mobile terminal updates the user information data in the preset application according to the current user authority. Therefore, it can effectively avoid the need to re-initialize each time the mobile terminal is unlocked. User information data in preset applications; in addition, since user mode switching does not involve the overall system of the mobile terminal, only part of the preset applications need to be updated with user information data, thus improving the response efficiency of the mobile terminal.

It should be noted that S205 and S206 are optional steps after S204, and one of the steps is selected to be executed according to the actual detection situation; that is, in the embodiment of the present invention, after S204, S205 or S206 may be executed, specifically The execution sequence of the steps may be determined according to the actual situation, which is not limited in the embodiment of the present invention; and, after the execution of S205 or S206, the current processing flow ends.

S207. When the mobile terminal does not collect the characteristic information of the current user, keep the screen locked.

When unlocking, after the mobile terminal collects the current user characteristic information, if the mobile terminal does not collect the user characteristic information, it keeps the screen locked state.

In particular, in the embodiment of the present invention, there may be situations where the user uses the mobile terminal and is not aligned with the device (for example, the camera on the mobile terminal) that collects user characteristic information in the mobile terminal. At this time, the mobile terminal does not collect the information of the current user. Characteristic information, therefore, even if the unlocking of the mobile terminal is triggered, the mobile terminal remains locked.

It should be noted that S202 and S207 are optional steps after S201, and one of the steps is selected to be executed according to the actual detection situation; that is, in the embodiment of the present invention, after S201, S202 or S207 can be executed, specifically The execution sequence may be determined according to the actual situation, which is not limited in this embodiment of the present invention.

An embodiment of the present invention provides an information protection method and a mobile terminal. When the mobile terminal is unlocked, it collects characteristic information of the current user; when the characteristic information of the current user is collected, it extracts characteristic data of the characteristic information of the current user; The feature data is compared to determine the current user authority; according to the current user authority, it is determined whether to update the user information data in the preset application to switch to the current user mode. By adopting the technical implementation scheme of the present invention, since the mobile terminal can obtain the feature data of the user feature information when the unlocking is triggered, even if different users use the same mobile terminal, they can only access the mobile terminal in the corresponding user feature data. Application operations are performed in the user mode of the preset application, so that unauthorized users cannot view user information data in the mobile terminal, thereby improving information security in the mobile terminal and improving user experience.
