The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, an embodiment of the present invention provides an unlocking method, which specifically includes the following steps:
and 102, if the analyzed terminal identification is the same as the pre-stored terminal identification, the terminal releases the screen locking state.
Through above-mentioned scheme, receive scanning command back through the camera scanning pattern information under the lock screen state according to the terminal to analyze out the terminal identification and compare with the terminal identification that prestores, only when the terminal identification that analyzes out with the terminal identification that prestores just can remove the lock screen state when the same, can provide higher safety guarantee, and need not brush the machine, can direct unblock, remain the data in the cell-phone simultaneously, it is more convenient. If the analyzed terminal identification is different from the prestored terminal identification, the terminal refuses to start the camera, so that malicious unlocking can be prevented, and the safety is improved.
The storage mode of the pattern information in the embodiment of the invention includes but is not limited to part or all of the following modes:
and (4) putting the card of the pattern information into the mobile phone packaging box, and directly printing the pattern information on the packaging box.
It should be noted that any means that enables the user using the mobile phone to obtain the pattern information is applicable to the present invention.
The pattern information is exemplified by printing the pattern information on a packing box or a card in the packing box, as shown in fig. 2, the related flow operation of the generation of the pattern information according to the embodiment of the present invention includes:
step 200: acquiring a terminal identifier of a mobile phone;
step 201: generating pattern information by taking the acquired terminal identification as a data source;
step 202: and printing the generated pattern information into a packing box or a card in the box.
If the user forgets the password, the pattern information is directly scanned in the screen locking state and the terminal identification is analyzed, when the analyzed terminal identification is consistent with the pre-stored terminal identification, the mobile phone screen locking password can be directly cleared, if the user packaging box or the card is lost, a pattern information can be regenerated according to the terminal identification of the user and sent to the user for unlocking, the operation is very convenient, and because only the user owns the pattern information, the safety of the user after clearing the password is improved.
In the implementation, when a user clears a screen locking password by scanning pattern information in a screen locking state, the camera needs to be triggered to be opened first, if the user unlocks by using the screen locking password each time, and in the screen locking state, the user forgets the screen locking password and needs to trigger to be opened; or the user sets to unlock by using a human face or a fingerprint, but the user needs to input the screen locking password after restarting the mobile phone every time, and in this case, the user needs to trigger to turn on the camera after forgetting the screen locking password.
There are many ways to trigger the camera to be turned on, and several are listed below.
The first trigger mode is that the user automatically triggers when inputting the password continuously and wrongly.
Specifically, the terminal can set the error times that the user can continuously input the screen locking password, when the user continuously inputs the screen locking password in the screen locking state, the terminal judges the continuous input times, and if the set times are reached, the terminal automatically triggers to start the camera.
And a second triggering mode is sliding touch operation triggering.
Specifically, the terminal can be set with a sliding touch operation first, and when the user forgets the screen locking password, the user triggers to turn on the camera in the screen locking state when performing special sliding touch operation on the display area.
According to the specific setting of the terminal to the sliding touch operation, the sliding touch operation can be divided into the following steps:
(1) a special symbol sliding touch operation.
The terminal can set a special symbol first, and when a user forgets a screen locking password and in a screen locking state, when the user performs special symbol sliding touch operation on the display area, the camera is triggered to be started.
As shown in fig. 3A, it is assumed that the terminal sets the V-shaped sliding touch operation trajectory to trigger to turn on the camera according to a setting operation instruction triggered by the user, and when the user performs the V-shaped trajectory sliding touch operation on the display area, the camera is turned on in the screen locking state.
(2) And a single-finger upward sliding touch operation.
As shown in fig. 3B, it is assumed that the terminal sets the one-directional upward sliding touch operation as a response mechanism for triggering and opening the camera according to the setting operation instruction triggered by the user, and when the user performs the one-directional upward sliding touch operation on the display area, the camera is opened in the screen locking state.
It should be noted that the above description of the sliding touch manner is only an example, and any sliding touch operation manner that can be applied to the embodiment of the present invention to trigger the camera to be turned on is applicable to the embodiment of the present invention.
And triggering by a key.
Specifically, the terminal can set a specific key on the screen locking interface, and when the user forgets the screen locking password, the camera can be triggered to be opened by touching the key.
It should be noted that the above description of the manner of triggering to turn on the camera is only an example, and any manner of turning on the camera that can be applied to the embodiment of the present invention is applicable to the embodiment of the present invention.
In implementation, after a user triggers and starts the camera in a screen locking state, pattern information can be scanned in various modes.
The first method is as follows: and directly scanning after the camera is started.
Specifically, after the terminal receives the scanning instruction in the screen locking state, the camera is started through triggering operation, and the pattern information is directly scanned through the camera.
The second method comprises the following steps: it is determined whether there is pattern information in the finder frame.
After the terminal receives the scanning instruction in the screen locking state, the camera is started through triggering operation, whether pattern information exists in the view-finding frame or not is determined through scanning of the camera, and when the pattern information exists, a user is prompted whether to scan or not.
If the user determines to scan, a scanning instruction is triggered, and the terminal scans pattern information through the camera after receiving the scanning instruction; otherwise, the scanning instruction is not triggered, and the terminal does not scan.
As shown in fig. 4, it is assumed that in the screen locking state, after a user performs a one-finger upward sliding touch operation on a display area to trigger the start of a camera, a terminal receives a scanning instruction, determines that pattern information exists in a view finder through scanning of the camera, and prompts the user whether to perform scanning in a text mode.
It should be noted that the above-mentioned manner for the user to scan the pattern information after triggering to open the camera in the screen lock state is only an example, and any manner for triggering to scan the pattern information after triggering to open the camera in the screen lock state is applicable to the embodiment of the present invention.
There are many kinds of pattern information, including but not limited to some or all of the following patterns:
one-dimensional bar codes and two-dimensional bar codes.
The two-dimensional bar codes can be divided into the following types:
(1) linear heap two-dimensional code.
Specifically, after the terminal identifier of the user is obtained, the terminal identifier of the user is used as a data source of pattern information to be encoded, and a mark is formed by several groups of regularly arranged bars, spaces and corresponding characters, wherein the mark is a generated linear stacked two-dimensional code.
(2) Matrix type two-dimensional code.
Specifically, after the terminal identification of the user is obtained, the terminal identification of the user is used as a data source of pattern information, coding is carried out in a rectangular space through different distribution of black and white pixels in a matrix, on the corresponding element position of the matrix, binary '1' is represented by the appearance of a point, binary '0' is represented by the non-appearance of the point, and the generated matrix type two-dimensional bar code is determined by the arrangement and combination of the points.
Wherein the shape of the dots comprises square dots and/or circular dots.
It should be noted that the two-dimensional barcodes may exist simultaneously, that is, when one of the two-dimensional barcodes is satisfied, the terminal analyzes the scanned pattern information to obtain an analyzed terminal identifier.
In implementation, in order to prevent others from maliciously making pattern information, for example, making a two-dimensional code for unlocking after acquiring a terminal identifier of another person, an optional scheme is provided in the embodiment of the present invention, and the terminal identifier is encrypted according to a specific encryption algorithm.
Specifically, a step is added between step 200 and step 201 in fig. 2, after the terminal identifier of the mobile phone is obtained, the terminal identifier is encrypted according to a specific encryption algorithm to become an unreadable segment of code, and the terminal identifier can only be displayed after being decrypted by a corresponding key, so that someone can be prevented from unlocking the mobile phone by using wrong pattern information.
Wherein the specific encryption algorithm includes, but is not limited to, one of the following algorithms: DES algorithm, MD5 algorithm, RSA algorithm.
After the pattern information is scanned, the pattern information needs to be decoded, and the methods for decoding the pattern information obtained by adopting different code systems are different, and the decoding methods of the pattern information are various, including the following methods:
in the first mode, a unique decoding method is preset before shipment.
Specifically, after the terminal identifier of the mobile phone is acquired, the terminal identifier is encoded by using only one code system before shipping to generate the pattern information, and at this time, the decoding mode of the pattern information is also uniquely determined.
In the second method, all decoding methods are set in advance in the terminal.
Specifically, in order to further improve the security, all decoding methods may be preset in the terminal, pattern information obtained by coding with different code systems corresponds to different decoding methods, the terminal determines the type of the pattern information after scanning the pattern information, and selects different decoding methods for different types.
In this case, the type of the pattern information may be various, for example, the pattern information of different production batches is different, the pattern information of the first production batch is a one-dimensional barcode, and the pattern information of the second production batch is a two-dimensional barcode, and at this time, the type of the pattern information scanned by the camera, specifically, the one-dimensional barcode or the two-dimensional barcode, may be determined first, and then the specific decoding method may be determined.
Optionally, after the terminal identifier is analyzed, whether the analyzed terminal identifier is consistent with the prestored terminal identifier is judged, and if so, the screen locking password is deleted; otherwise, the screen locking password is not deleted.
Specifically, whether the analyzed terminal identifier is consistent with the pre-stored terminal identifier is judged by comparing whether the data of the position corresponding to the analyzed terminal identifier and the pre-stored terminal identifier are the same, and if the data of each bit are the same, the analyzed terminal identifier is consistent with the pre-stored terminal identifier; and if the data of at least one bit is different, the analyzed terminal identification is inconsistent with the pre-stored terminal identification.
There are many comparison results between the analyzed terminal identifier and the pre-stored terminal identifier, which are exemplified below.
Assuming that the analyzed terminal identifier is 869019034863357 and the pre-stored terminal identifier is 869019034863357, wherein the total length of the two terminal identifiers is 15 bits, the data of the relative positions are compared, and the data of each bit are the same as the result, that is, the comparison result between the analyzed terminal identifier and the pre-stored terminal identifier is consistent.
Assuming that the analyzed terminal identifier is a000008550221C and the pre-stored terminal identifier is 120a008550221C, where the total length of the two terminal identifiers is 14 bits, the data at the relative positions are compared, and the result data are different, that is, the comparison result between the analyzed terminal identifier and the pre-stored terminal identifier is inconsistent.
It should be noted that the above-mentioned result of comparing the analyzed terminal identifier with the pre-stored terminal identifier is only an example, and any result of comparing the analyzed terminal identifier with the pre-stored terminal identifier that can be applied to the embodiment of the present invention is applicable to the embodiment of the present invention.
Optionally, in order to prevent some users from unlocking maliciously, the embodiment of the present invention further sets a mode that the number of times of user authentication can be limited.
Specifically, the terminal refuses to start the camera after the number of times of user authentication failure reaches the number limit.
Wherein, a threshold value can be set for the number of times of user authentication failure, and there are various ways of setting the threshold value, which are listed as follows:
the first mode is set directly before delivery.
Specifically, the time length that the user can verify and the number of times that the user fails to verify are set by the manufacturer before the mobile phone leaves the factory.
If the manufacturer uniformly sets that the number of times of user authentication failure in 1 minute cannot exceed 5 times before the mobile phone leaves a factory, the user authentication failure in 1 minute cannot exceed 5 times, and the user authentication failure can be continuously verified by scanning the pattern information through the camera, otherwise, the terminal refuses to start the camera.
And the second mode is set by the user.
Specifically, after the user obtains the mobile phone, the user sets the verification time and the verification failure times, and the user can set the verification time according to the user's will, so that the mobile phone is more convenient to use.
If the user sets that the number of times of authentication failure in 1 minute cannot exceed 3 times, the user can continue to scan pattern information through the camera for authentication when the number of times of authentication failure in 1 minute does not exceed 3 times, otherwise the terminal refuses to start the camera.
It should be noted that the above-mentioned manner for setting the threshold is only an example, and any manner that can be applied to setting the threshold in the embodiment of the present invention is applicable to the embodiment of the present invention.
After the threshold value is set, after the terminal receives an instruction of scanning the terminal identification in a screen locking state, whether the number of times of user authentication failure in a set time length reaches the set threshold value is determined, if yes, the terminal refuses to start the camera, otherwise, the terminal prompts the user of authentication failure.
Assuming that the terminal sets prompt information for displaying user authentication failure in a text form, when the number of times of authentication failure of the user in 1 minute does not reach the threshold value of 5 times, the terminal prompts the user and displays the prompt information in a text and/or pattern form, where fig. 5 is an example of text display.
Assuming that the terminal sets prompt information for displaying user authentication failure in a text form, when the number of times of authentication failure of the user reaches a threshold value of 5 times within 1 minute, the terminal prompts the user, refuses to turn on a camera, and displays the prompt information in a text and/or pattern form, where fig. 6 is an example of text display.
It should be noted that the above prompt for the user authentication failure is only an example, and any prompt information for the user authentication failure that can be applied to the embodiment of the present invention is applicable to the embodiment of the present invention.
As shown in fig. 7, the relevant process operations of the method for unlocking according to the embodiment of the present invention include:
step 700: the terminal receives a scanning instruction in a screen locking state;
step 701: the terminal responds to the instruction to start the camera;
step 702: after the terminal detects the pattern information through the camera, the pattern information is decrypted to obtain the analyzed terminal identification;
step 703: the terminal compares the analyzed terminal identification with the prestored terminal identification;
step 704: the terminal judges whether the comparison result is consistent, if so, the step 705 is executed, otherwise, the step 707 is executed;
step 705: the terminal releases the screen locking state;
step 706: the terminal clears the original lock screen password;
step 707: the terminal does not release the screen locking state;
step 708: the terminal judges whether the number of times of user authentication reaches a threshold value, if so, step 709 is executed, otherwise, step 710 is executed;
in step 710, the terminal prompts the user that the authentication fails, and returns to step 702.
In the embodiments provided in the present application, the method provided in the embodiments of the present application is described from the perspective of the terminal as an execution subject. In order to implement the functions in the method provided by the embodiment of the present application, the terminal may include a hardware structure and/or a software module, and implement the functions in the form of a hardware structure, a software module, or a hardware structure and a software module. Whether any of the above-described functions is implemented as a hardware structure, a software module, or a hardware structure plus a software module depends upon the particular application and design constraints imposed on the technical solution.
Based on the same concept, as shown in fig. 8, an embodiment of the present invention provides a terminal for unlocking, where the terminal includes: a processor 800 and a memory 801, wherein the memory 801 stores program code, and when one or more computer programs stored in the memory 801 are executed by the processor 800, the terminal is caused to perform the following processes:
