Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, an embodiment of the present invention provides a data hiding method, including the following steps:
s11, acquiring unlocking information provided by a current user, and judging whether the unlocking information meets a preset unlocking condition;
if yes, entering S12, executing unlocking operation, and collecting the face image of the current user;
s13, judging whether the face image is a preset main target face image;
if not, the step of S14 is carried out, and corresponding target data are determined according to the face image;
and S15, hiding the target data according to a preset rule.
In the above S11, when the current user performs an unlocking operation on the terminal device (e.g., a smart phone), it is first determined whether the unlocking information provided by the current user satisfies a preset unlocking condition, if so, the process goes to S12, and if not, the terminal device does not perform the unlocking operation, so that the current user cannot further use the terminal device; wherein, the unlocking information includes biological characteristic information (such as facial characteristic information, fingerprint characteristic information, iris characteristic information, voice characteristic information, etc. of the current user), password information, sliding information, key information and pattern information, specifically, the owner generally presets the unlocking condition for unlocking the terminal device on the terminal device, for example, the fingerprint, face image or voice for unlocking the terminal device is pre-entered, or the unlocking password, unlocking pattern, etc. are pre-set, specifically, for example, the owner sets the digital password as the condition for unlocking the terminal device, when the current user unlocks the terminal device, the terminal device will receive the digital password input by the current user and judge whether the digital password is consistent with the digital password preset by the owner, if so, it can be determined that the unlocking information provided by the current user satisfies the preset unlocking condition, then S12 may be entered; if the unlocking information provided by the current user does not meet the preset unlocking condition, the current user can not use the terminal equipment.
In S12, specifically, after the terminal device performs the unlocking operation, the front-facing camera on the terminal device may be turned on to acquire the face image of the current user, so as to subsequently confirm the identity of the current user according to the acquired face image.
In the above S13, the owner may input the face image of the owner or the face image of another person who the owner completely trusts into the terminal device in advance as the main target face image, for example, the owner may input the face image of the owner or the face image of another person who the owner completely trusts into the terminal device as the main target face image by taking a picture on site or loading a photograph, or the like, in other words, the owner may set one or more main target face images according to actual needs; after the terminal equipment acquires the face image of the current user, further judging whether the face image is a preset main target face image, if so, indicating that the identity of the current user is the owner or a person completely trusted by the owner, and further not hiding any data by the terminal equipment; if not, the process goes to S14 for relevant operation.
Referring to fig. 2, specifically, whether the acquired face image is a preset primary target face image may be determined by:
s131, matching the face image with a plurality of credible face images preset in a database one by one, and judging whether credible face images matched with the face images exist or not, wherein the credible face images comprise secondary target face images and primary target face images;
if not, the process proceeds to S133, and determines that the face image is not the primary target face image, at which point the process may further proceed to S14 for performing the correlation operation.
Specifically, after S131, the method further includes:
if yes, entering S132, and judging whether the matched reliable face image is a main target face image;
if not, the process proceeds to S133, and determines that the face image is not the primary target face image, at which point the process may further proceed to S14 for performing the correlation operation.
In the above S131, specifically, the owner may enter a face image of the owner and a face image of another person that the owner can trust into a database of the terminal device as trusted face images in advance by taking a picture on site or loading a picture, and the like, where in the trusted face images, the owner may set the face image of the owner or the face image of another person that the owner completely trusts as a primary target face image according to actual needs, and the remaining trusted face images are set as secondary target face images, and specifically, the owner may add the face image of the owner or the face image of another person that the owner completely trusts to a preset display database to identify the face image as the primary target face image, and add the remaining trusted face images to a preset hidden database to identify the face image as the secondary target face image;
specifically, after the terminal device collects a face image of a current user, the terminal device matches the face image with a plurality of trusted face images preset in a database one by one, and determines whether a trusted face image matching the face image exists, if yes, the process goes to S132; if not, the process proceeds directly to S133.
In the above S132, when the terminal device determines that the trusted face image matched with the face image exists in the database, it indicates that the current user is the owner or the trusted person of the owner, that is, it indicates that the matched trusted face image is the primary target face image or the secondary target face image, at this time, it may be further determined whether the trusted face image is the primary target face image through the identifier, and if so, the terminal device may not hide any data; if not, the process proceeds directly to S133.
In the above S133, specifically, when the terminal device determines that the trusted face image matching with the face image does not exist in the database, the terminal device may determine that the acquired face image is not the primary target face image and is not the secondary target face image, that is, the current user is not the owner or the owner is trusted, and then S14 may be entered to perform the relevant operation; when the terminal device determines that the database has the trusted face image matched with the face image and the matched trusted face image is not the primary target face image, the terminal device can determine that the acquired face image is not the primary target face image but the secondary target face image, and then the operation can be performed in S14.
In the above S14, specifically, for a case that the current user may be a trusted person, the owner may associate the secondary target face images with corresponding data to be hidden according to actual needs, respectively, so as to define target data corresponding to the secondary target face images, and for a case that the current user may be a person whose owner is not trusted, the owner may define target data corresponding to the non-trusted face images (i.e., neither the primary target face image nor the secondary target face image) by adding the data to be hidden to a preset default database according to actual needs; specifically, in the foregoing process, when the terminal device determines that the acquired face image is a secondary target face image, the terminal device may determine target data corresponding to the secondary target face image accordingly, and at this time, the process may proceed to S15 for related operations; and when the terminal device determines that the acquired face image is neither the primary target face image nor the secondary target face image, the terminal device may determine the target data corresponding to the untrusted face image accordingly, and at this time, the process may proceed to S15 for related operations.
In an alternative embodiment, specifically, before the above S11, the target data may be defined by:
s11a, receiving an operation instruction made by a user to the application program;
and S11b, adding the application program into a preset application management list according to the operation instruction so as to define the application data corresponding to the application program as target data.
In the embodiment, the owner can define the data to be hidden as the target data through a manual operation mode according to the requirement; specifically, for the situation that the current user may be a trusted person, a corresponding application management list may be associated with each secondary target face image in advance, and the owner may make an operation instruction for adding the application program to the preset application management list in advance by an addition method, a pull-in method, and the like according to needs, so as to define application data corresponding to the application program as target data, where the application data includes data such as an icon (i.e., a shortcut) corresponding to the application program, a file, a folder, and the like, for example, the application program added to the application management list is a mobile phone call application, and then the corresponding application data includes an icon, a call record, a contact, a call record, and the like corresponding to the mobile phone call application; aiming at the condition that the current user is probably a person whose owner is not trusted, the owner can associate an application management list with a preset default database in advance, and the owner can make an operation instruction for adding the application program into the application management list to the application program in advance through an adding method, a dragging method and the like according to needs, so that the application data which needs to be hidden is added into the preset default database through the application management list, and the application data corresponding to the application program is defined as target data.
In S15, when the terminal device determines the target data corresponding to the face image according to the face image, the target data is hidden according to a preset rule, so as to achieve the purpose of hiding the corresponding data according to the identity of the current user.
Referring to fig. 3, in an alternative embodiment, after the step of hiding the target data according to the preset rule, the method further includes:
s156, acquiring current geographic position information;
and S157, sending the current geographic position information and the face image to an authorization terminal.
In this embodiment, the owner may grant the other terminal device in advance with the right to acquire the data of the terminal device, so as to designate the other terminal device as an authorization terminal, and the owner may select the authorization terminal according to actual needs, for example, the owner may select a terminal device frequently used by family or friends as the authorization terminal, and the number of the authorization terminals may be one or more, and the owner may determine according to actual needs; specifically, the terminal device receiver determines the specific terminal device as an authorized terminal by granting the specific terminal device with an authorization instruction for obtaining data of the terminal device for operation input, specifically, for example, the owner may establish a remote communication connection with the cloud server by installing a specific application (App) on the terminal device, and then perform operation input through the App to determine the specific terminal device as an authorized terminal, for example, the owner may make an authorization instruction by inputting a unique identifier of the specific terminal device on the App, and when the terminal device receives the authorization instruction, the terminal device determines the specific terminal device as an authorized terminal, where the unique identifier is an identity identifier capable of representing an identity of the specific terminal device, such as an account for logging in the App, or a device identifier (such as a bluetooth Mac address of the specific terminal device, and a bluetooth Mac address of, IP address, etc.), or may be a device communication number (such as a mobile phone number), etc., which is not particularly limited; in this embodiment, specifically, after the terminal device hides the target data according to the preset rule, the terminal device obtains its own geographic location information through modes such as a GPS (for example, automatically turning on a GPS module on the terminal device), and then sends the obtained current geographic location information and the collected face image to the authorization terminal in forms such as a message (for example, a short message), so that the owner can clearly know the identity of the user who uses the owner personal terminal device (i.e., the owner may be a trusted person or an untrusted person) through the authorization terminal, and where the user uses the owner's terminal device, thereby improving the user experience.
Referring to fig. 4, in a preferred embodiment, before the step S156, the method further includes:
s156a, judging whether the face image is a secondary target face image;
if not, the above step S156 is executed.
In the above S156a, the specific principle process of determining whether the face image is the secondary target face image is similar to the process of the foregoing S131 to S133, and details thereof are not repeated, it should be noted that, before this step, if the terminal device has determined that the acquired face image is the primary target face image or the secondary target face image or the untrusted face image, this step may be omitted;
specifically, when the terminal device determines that the acquired face image is an untrusted face image (i.e., neither a primary target face image nor a secondary target face image), the current geographic position information of the terminal device is acquired, and the acquired current geographic position information and the acquired face image are sent to an authorization terminal for the owner or a trusted person to view; in this embodiment, the owner can choose to set as required when the terminal device recognizes that the current user is a person whose owner is not trusted, and then follow-up operation of sending the current geographic position information and the collected face image to the authorization terminal is performed, so that on the premise of ensuring the security and privacy of personal data on the terminal device, the ring that the owner can trust is effectively reduced because the owner sets up the limit on the terminal device, and meanwhile, aiming at the condition that the terminal device is lost, the owner can conveniently find the lost terminal device by checking the face image and the geographic position information received by the authorization terminal, thereby improving the user experience.
In the two embodiments corresponding to fig. 3 and fig. 4, the owner may select and set according to the actual situation of the owner, for example, if the owner has one or more standby terminal devices in addition to the frequently used private terminal device, one or more standby terminal devices may be selected as the authorized terminal, and at this time, the technical solution corresponding to fig. 3 may be selected for implementation; if the owner only has one terminal device, the terminal device frequently used by family or friends can be selected as the authorization terminal, and the technical scheme corresponding to fig. 4 can be selected to be implemented.
Referring to fig. 5, in an alternative embodiment, the step of hiding the target data according to the preset rule includes:
s151, acquiring the current time and a preset effective hiding time period associated with the target data;
s152, judging whether the current time exceeds an effective hiding time period;
if not, S153 is executed to hide the target data.
In this embodiment, after the owner defines the corresponding target data, a valid hiding time period may be associated with the corresponding target data, where the owner may set the valid period according to the actual situation of the owner, for example, for a situation that a current user may be a trusted person (for example, the owner is reading children), the valid hiding time period may be flexibly set, for example, for a part of the target data (for example, application data corresponding to a certain application program), the valid hiding time period may be set to be from 8 o 'clock to 8 o' clock every week, or from 8 o 'clock to 8 o' clock every morning on monday, or from 8 o 'clock to 8 o' clock on night, from 7 o 'clock on tuesday night to 9 o' clock, from 9 o 'clock to 12 o' clock on saturday morning, and for another part of the target data (for example, application data corresponding to another one or more application programs), the effective hiding time period can be set to be 'every day', so that the safety and the privacy of personal data can be ensured, and meanwhile, the hiding mode of the personal data can be more flexible; for the situation that the current user may be a person whose owner is not trusted, the effective hiding time period can be set to be 'determined', for example, the effective hiding time period can be set to be 'always', so that even if the current user successfully unlocks the terminal equipment of the owner, the target data preset by the owner for the needs cannot be obtained, and the safety and privacy of personal data can be effectively ensured; in this embodiment, for example, specifically, if the current user is the son who is reading (still in the reading learning phase) of the owner, when the terminal device recognizes that the current user is the son who is reading the owner, it is first determined whether the current time is within an effective hiding time period, for example, an effective hiding time period associated with application data corresponding to a certain game application is 8 am to 8 pm every morning, for example, three pm in the wednesday, the owner wants to play a game using the terminal device of the owner when the owner is reading the son, then after the terminal device of the owner is unlocked, the terminal device determines that the current time falls within the effective hiding time period, and the terminal device will automatically hide the application data corresponding to the game application, so that the owner cannot find the game application when reading the son and cannot play the game; and if the owner wants to use the terminal equipment of the owner to play the game at 9 o' clock on saturday night, the terminal equipment cannot hide the application data corresponding to the game application.
An embodiment of the present invention further provides a readable storage medium, where a computer program is stored on the readable storage medium, and when the computer program is executed by a processor, the data hiding method in any of the above embodiments is implemented.
