Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

The inventor finds that the electronic equipment is triggered to unlock by using a track recognition mode commonly used at present, for example, when the electronic equipment is triggered to light a screen or trigger to run content (or application) with access authority, the electronic equipment displays the identifier layout shown in fig. 1, so that a user draws a track in the identifier layout by connecting identifiers, and when the track drawn by the user is matched with a preset track, the lock is unlocked, but when the track is unlocked in a public place, the probability that the track drawn by the user is peeped by a bystander is high, and hidden danger is brought to the use safety of the electronic equipment;

the inventor also finds that if an information processing method is implemented, the method is applied to the electronic device, as shown in fig. 2, and in step 101, an instruction is received; in step 102, executing an instruction to present a first identification layout; the first identifier layout is selected from at least two different second identifier layouts, the second identifier layouts are determined based on a first identifier sequence (corresponding to a password preset by a user), the first identifier sequence is obtained based on a third identifier layout (namely the identifier layout when the user presets the password), and the third identifier layout is different from the second identifier layout; in step 103, resolving the operation obtained based on the first identification layout (the operation is the user-triggered unlocking operation implemented by the user based on the first identification layout); in step 104, detecting whether a second identification sequence (the second identification sequence is a sequence of identifications triggered by the operation track of the operation in sequence in the first identification layout) is matched with the first identification sequence, and responding to the operation based on the matching result;

it can be seen that, the user performs an operation on the first identifier layout to draw an operation track corresponding to the preset first identifier sequence, so as to trigger unlocking, and it seems to an observer that the user performs unlocking on the track, and actually the user performs an operation to draw an operation track corresponding to the first identifier sequence; moreover, because the first identifier layout is selected from at least two different second identifier layouts, when the first identifier layouts presented by the electronic equipment are different, the operation tracks corresponding to the first identifier sequences (corresponding unlocking passwords) implemented by the user in the different first identifier layouts are different, so that the possibility that the operation tracks are identified by a spectator to trigger unlocking by using the operation tracks is eliminated, and the data security of the electronic equipment is ensured.

Example one

The embodiment describes an information processing method, which can be applied to electronic devices such as smart phones and tablet computers; as shown in fig. 3a, the information processing method according to the present embodiment includes the steps of:

in step 201, the electronic device presents a third identification layout.

The third identification layout is used for a user to set a first identification sequence (namely an unlocking password set by the user), the identification in the third identification layout can adopt one or a combination of letters, numbers and other types of characters, and when the first identification sequence only adopts the numbers from 1 to 9, the third identification layout presented by the electronic equipment can adopt a nine-square form presenting the numbers from 1 to 9; when the first identification sequence adopts English letters, the first identification sequence can be in the form of a virtual keyboard presenting 26 English letters; that is to say, the type of the identifier presented in the first identifier layout depends on the type of the identifier in the first identifier sequence to be set by the user, and in practical applications, the third identifier layout including the corresponding type identifier may be presented according to the type of the identifier in the first identifier sequence preset by the user.

The marks in the third mark layout may be arranged in a regular array, that is, the marks in the third mark layout form straight lines in the longitudinal and transverse directions, or the marks in the third mark layout may be arranged in an irregular manner, that is, the marks in the third mark layout are arranged in a disorder manner.

Step 202, based on the third identifier layout, a first identifier sequence is obtained.

The electronic device may obtain the first identifier sequence in a form of supporting a point touch operation, that is, the electronic device prompts to sequentially trigger identifiers corresponding to the first identifier sequence (that is, a password to be set by a user) in the third identifier layout through the point touch operation;

the electronic device may further obtain the first identifier sequence in a form supporting a sliding operation, that is, the electronic device prompts to sequentially trigger identifiers corresponding to the first identifier sequence (that is, a password to be set by a user) in the third identifier layout in a form of performing a sliding operation in the third identifier layout.

The first identification sequence here can be used to authenticate access of the electronic device itself (e.g., when the electronic device is triggered to wake up from a hibernation state), to authenticate access of a specific application in the electronic device (e.g., an instant messaging application, an application presenting multimedia files local to the electronic device), or to authenticate access of specific content in the electronic device (e.g., multimedia content); that is, the operation track of the user performing the operation on the electronic device corresponds to the first identification sequence, and the electronic device can be triggered to unlock the lock of the electronic device, the specific application or the specific content.

In this embodiment, the same identifiers cannot continuously appear in the first identifier sequence, so as to avoid a situation that an operation trajectory corresponding to the first identifier sequence is drawn by an operation in the first identifier layout that cannot be presented by the electronic device subsequently, where the length of the first identifier sequence is smaller than the total number of types identified in the third identifier layout, for example, when the third identifier layout is a 9-squared figure 1, the length of the first identifier sequence may be smaller than the total number of types identified in the third identifier layout (9), or may be equal to the total number of types identified in the third identifier layout (9).

Step 203, receiving an instruction.

The instruction can trigger the electronic device to unlock itself (for example, when the electronic device is triggered to light up the display screen from a dormant state), unlock a specific application (for example, when an application with a high security level, such as bank client software, is triggered to run, authentication is required), or unlock specific content (for example, when multimedia content with access right is accessed, authentication is required);

the instructions herein may also be instructions to directly dismiss the electronic device from presenting the first identification layout; when the electronic equipment receives the instruction, the electronic equipment needs to detect and acquire the operation implemented by the user by displaying the first identifier, verify whether a second identifier sequence corresponding to the operation track implemented by the user is matched with the preset first identifier sequence, unlock the electronic equipment if the second identifier sequence is matched with the preset first identifier sequence, and explain the following steps.

Step 204, presenting a first identification layout.

The marks in the first mark layout may be arranged in a regular array, that is, the marks in the first mark layout form straight lines in the longitudinal and transverse arrangements, or the marks in the first mark layout may be arranged in an irregular arrangement, that is, the marks in the first mark layout are arranged in a disorder manner.

The first identifier layout is selected from at least two different second identifier layouts, the at least two different second identifier layouts are determined based on the first identifier sequence, and one of the at least two different second identifier layouts may be the same as the first identifier layout (that is, the identifier layout for setting the first identifier sequence may be the same as one of the at least two subsequently acquired second identifier sequences); of course, the at least two different second identification layouts may also be completely different from the first identification layout;

for example, when the third identifier layout in the conventional form shown in fig. 3e is adopted (that is, the third identifier layout supporting the point touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in the regular arrangement shown in fig. 3i or fig. 3j may be selected as the first identifier layout to be presented; at the moment, the at least two second identifier layouts are different from the third identifier layout;

for another example, when the third identifier layout in the regular arrangement shown in fig. 3d is adopted (that is, the third identifier layout supporting the point-and-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in the regular arrangement shown in fig. 3d and fig. 3h can be selected as the first identifier layout to be presented, and at this time, one of the at least two second identifier layouts is the same as the third identifier layout;

for another example, when the third identifier layout in regular arrangement shown in fig. 3d is adopted (that is, the third identifier layout supporting the point-and-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in regular arrangement shown in fig. 3g or fig. 3h can be selected as the first identifier layout to be presented, and at this time, at least two of the second identifier layouts are different from the third identifier layout;

for another example, when the third identifier layout with irregular arrangement shown in fig. 3f is adopted (that is, the third identifier layout supporting the point-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts with irregular arrangement shown in fig. 3k and fig. 3l may be selected as the first identifier layout to be presented, and at this time, at least two of the second identifier layouts are different from the third identifier layout;

of course, when the third identifier layout in the irregular arrangement shown in fig. 3f is adopted (that is, the third identifier layout supporting the point-and-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in the irregular arrangement shown in fig. 3g and fig. 3h may be selected as the first identifier layout to be presented, and at this time, at least two of the second identifier layouts are different from the third identifier layout.

It should be noted that the at least two different second identification sequences may be determined immediately according to the first identification sequence after the first identification sequence is obtained, or may be determined according to the first identification sequence set by the user only when an instruction is received that the first identification sequence needs to be presented;

for example, the electronic device is provided with a sequence 1 (corresponding to a first identification sequence of the electronic device) for unlocking the electronic device itself, the application 1 in the electronic device is provided with a sequence 2 (corresponding to the first identification sequence of the application 1) for unlocking, the application 2 in the electronic device is provided with a sequence 3 (corresponding to the first identification sequence of the application 2) for unlocking, and the sequences 1, 2 and 3 are different sequences;

the electronic equipment instantly determines at least two different second identifier layouts corresponding to the sequence 1 after acquiring the sequence 1, and only stores the sequence 2 after acquiring the sequence 2; when the electronic equipment receives an instruction to trigger unlocking of the electronic equipment (for example, the electronic equipment is triggered to light up the display screen from a dormant state), selecting one of at least two different predetermined second identifier layouts as a first identifier layout and presenting the first identifier layout on the display screen;

when the electronic device receives an instruction to trigger the electronic device to unlock the application 1 (for example, when the user triggers an icon of the application 1 to run the application 1), the corresponding at least two different second identifier layouts are determined according to the sequence 2, and one of the at least two different second identifier layouts is selected as the first identifier layout and is presented on the display screen.

In step 205, an operation performed on the first tag layout is detected.

The electronic equipment can detect whether the operation carried out by the user is received on the first identification layout at regular time after the first identification layout is presented on the display screen, and if the operation is detected, the subsequent steps are executed.

At step 206, the operation obtained based on the first identification layout is parsed.

Analyzing the operation point of the detected operation, and judging whether the operation point meets a preset condition, wherein the preset condition is as follows: the operating points of the operation form a continuous uninterrupted operating track; the trajectory between any two adjacent marks triggered by the operation trajectory in the first mark layout is a straight line segment; any two adjacent identifiers triggered by the operation track in the first identifier layout correspond to two adjacent identifiers in the first identifier sequence;

when the preset condition is met, obtaining an operation track of the operation based on the analyzed operation point and carrying out subsequent processing; otherwise, the operation performed on the first identification layout continues to be detected.

And step 207, analyzing the identifiers sequentially triggered by the operation tracks in the first identifier layout, and obtaining a second identifier sequence based on the identifiers sequentially triggered by the operation tracks.

Matching the operation track of the operation with the position in the first identifier layout, sequentially locating identifiers on the operation track after matching, and determining a second identifier sequence based on the sequentially matched identifiers, for example, when the operation track sequentially triggers identifiers 1, 2 and 3 in the first identifier sequence, determining that the corresponding second identifier sequences are 1, 2 and 3; when the operation track sequentially triggers the identifiers 1, 2, 3, 2 and 3 in the first identifier sequence, the corresponding second identifier sequence is determined to be 12323.

And step 208, unlocking when the second identification sequence is detected to be matched with the first identification sequence.

For example, when the received instruction is to trigger unlocking of the electronic device itself, a main interface (e.g., launcher interface) of the electronic device is presented; when the received instruction is to trigger unlocking of an application, such as the application 1, the application 1 is run and an interactive interface of the application 1 is presented.

The above steps will be described with reference to an actual usage scenario.

Scene 1: the method comprises the steps that a user triggers the electronic equipment in a dormant state, the electronic equipment obtains an unlocking password (corresponding to a second identification sequence) input by the user according to an operation track corresponding to an operation implemented by the user, and when the unlocking password is matched with a preset unlocking password (corresponding to a first identification sequence), the locking state of the electronic equipment is released and a launcher interface is displayed; the specific implementation steps are as follows:

1) the user sets the character type of the unlocking password and sets the unlocking password (corresponding to the first identification sequence) through the interactive interface shown in fig. 3 b.

Taking the selected number as an example, the electronic device may obtain an unlocking password of the electronic device set by the user through a nine-square grid (corresponding to the third identifier layout arranged regularly) as shown in fig. 3c, the user may set the unlocking password in the nine-square grid in a point-touch manner, the electronic device detects the operation of the user and analyzes an operation trajectory of the operation, and connects identifiers 1, 2, 3, and 4 sequentially triggered by the operation trajectory in the nine-square grid to obtain an unlocking password 1234 (corresponding to the first identifier sequence) input by the user; or, the user may set an unlocking password by performing an operation in a nine-grid (corresponding to a third identifier layout arranged regularly) as shown in fig. 3d, the electronic device detects that the operation points of the operation form a continuous operation track, the track between adjacent identifiers passed by the operation track in the third identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, which meets the preset condition, and connects identifiers 1, 2, 3, and 4 sequentially triggered by the analyzed operation track of the user performing the operation in the nine-grid to obtain the unlocking password 1234 (corresponding to the first identifier sequence);

taking the case that the user selects letters as the unlocking password, the electronic device may obtain the unlocking password (corresponding to the first identifier sequence) of the electronic device set by the user through a 26-letter virtual keyboard (corresponding to the third identifier layout in the conventional form) as shown in fig. 3e, the user may set the unlocking password in the virtual keyboard through a point-touch form, the electronic device recognizes the operation of the user, and the identifiers a, b, c, and d sequentially triggered by the user in the nine-square grid are connected to obtain the unlocking password abcd (corresponding to the first identifier sequence);

the first identification sequence 1234 is taken as an example for explanation.

Fig. 3b and fig. 3c both illustrate the third identifier layout as a regular arrangement manner, and the third identifier layout may also adopt the above irregular arrangement manner, one example is as described in fig. 3f, a user may implement an operation shown by a dotted line in the irregularly arranged nine-palace grid shown in fig. 3f to set an unlocking password, an operation point where the electronic device detects the operation forms a continuous operation track, a track between adjacent identifiers where the operation track passes in the third identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, which meets the above preset condition, and the analyzed identifiers 1, 2, 3, and 4 sequentially triggered by the operation track where the user implements the operation in the irregular nine-palace grid are connected to obtain the unlocking password 1234 (corresponding to the first identifier sequence).

2) When the electronic device is in a dormant state, the electronic device is triggered to light the display screen (for example, a user triggers a home key of the electronic device to trigger the electronic device to light the screen), the electronic device presents the first identifier layout and detects the operation of the user, and an unlocking password (corresponding to the second identifier sequence) corresponding to an operation track of the user for implementing the operation in the first identifier layout is obtained.

The electronic device determines at least two different second identifier layouts according to an unlocking password (corresponding to the first identifier sequence) of the electronic device preset by a user, where the at least two different second identifier layouts may also be predetermined, selects a third identifier layout from the at least two different second identifier layouts and presents the third identifier layout on a display screen, and when the first identifier sequence is set to 1234 through the third identifier layout shown in fig. 3c, 3d, or 3f, examples of the different second identifier layouts are shown in fig. 3g and 3h, or shown in fig. 3k and 3 l;

when the electronic device selects the second identifier layout shown in fig. 3g as the first identifier layout and presents the second identifier layout, the user performs the operation shown by the dotted line in fig. 3g, the electronic device detects that the operation points of the operation form a continuous track, the track between adjacent identifiers passed by the operation track in the first identifier layout is a straight line segment, and the operation track does not pass through the position corresponding to the different identifiers in the first identifier sequence, the preset condition is met, and the identifiers sequentially triggered by the analyzed operation track in the first identifier layout are connected to obtain the unlocking password (corresponding to the second identifier sequence) corresponding to the operation track operated by the user;

when the electronic device selects the second identifier layout shown in fig. 3h as the first identifier layout and presents the second identifier layout, the user may detect that the operating points of the operation form a continuous track through the operation shown by the dotted line in fig. 3h, the track between adjacent identifiers passed by the operating track in the first identifier layout is a straight line segment, and the operating track does not pass through the position corresponding to the different identifier in the first identifier sequence, so as to meet the preset condition, and connect the identifiers sequentially triggered by the analyzed operating track in the third identifier layout to obtain the unlocking password (corresponding to the second identifier sequence) input by the user through the operation;

for the spectator, it seems that the user is performing the trajectory unlocking operation of the related art (i.e., unlocking by using a specific trajectory), but the user draws an operation trajectory corresponding to a preset unlocking password (corresponding to the first identifier sequence) by an operation to trigger unlocking, and because the first identifier layout is selected from at least two different second identifier layouts, when the first identifier layouts presented by the electronic device are different, the operation trajectories performed by the user in the different first identifier layouts and corresponding to the preset unlocking password (corresponding to the first identifier sequence) are also different, so that the possibility that the operation trajectory is recognized by the spectator to trigger unlocking by using the operation trajectory is eliminated, and the data security of the electronic device is ensured.

3) And matching the unlocking password input by the user with the preset password, and responding to the operation based on the matching result.

When the unlock password (corresponding to the second identification sequence) input by the user matches the preset unlock password (corresponding to the first identification sequence), the electronic device is unlocked, and a home screen of the electronic device, such as a launcher interface, may be presented.

Scene 2: the method comprises the steps that a user triggers the electronic equipment to run an application 1, the electronic equipment obtains an unlocking password (corresponding to a second identification sequence) input by the user according to an operation track corresponding to an operation implemented by the user, and when the unlocking password is matched with a preset unlocking password (corresponding to a first identification sequence), the locking state of the application 1 is released and an interactive interface of the application 1 is displayed; the specific implementation steps are as follows:

Taking the selected number as an example, the electronic device may obtain an unlocking password (corresponding to the first identifier sequence) of the electronic device set by the user through a nine-square grid (corresponding to the third identifier layout) as shown in fig. 3c, the user may set the unlocking password in the nine-square grid through a point-touch manner, the electronic device detects the operation of the user and recognizes an operation trajectory of the operation, and identifiers 1, 2, 3, and 4 sequentially triggered by the operation trajectory in the nine-square grid are connected to obtain an unlocking password 1234 (corresponding to the first identifier sequence); or, the user may set an unlocking password by performing an operation in a nine-grid (a third identifier layout arranged in a corresponding rule) as shown in fig. 3d, the electronic device detects that the operation points of the operation form a continuous operation track, the track between adjacent identifiers passed by the operation track in the third identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, which meets the preset condition, and connects identifiers 1, 2, 3, and 4 sequentially triggered by the analyzed operation track performed by the user in the nine-grid to obtain the unlocking password 1234 (corresponding to the first identifier sequence);

taking the case that the user selects letters as the unlocking password, the electronic device may obtain the unlocking password (corresponding to the first identifier sequence) of the electronic device set by the user through a 26-letter virtual keyboard (corresponding to the third identifier layout) as shown in fig. 3e, the user may set the unlocking password in the virtual keyboard in a point-touch manner, the electronic device recognizes the operation of the user, and connects identifiers a, b, c, and d sequentially triggered by the user in the nine-square grid to obtain the unlocking password abcd (corresponding to the first identifier sequence);

the third identifier layout may also adopt the above irregular arrangement manner, one example is as shown in fig. 3f, a user may set an unlocking password by performing an operation in the irregularly arranged nine-palace lattice shown in fig. 3f, the electronic device detects that an operation point of the operation forms a continuous operation track, a track between adjacent identifiers that the operation track passes through in the third identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, which meets the above preset condition, and the identifiers 1, 2, 3, and 4 sequentially triggered by the operation track that the analyzed user performs the operation in the irregular nine-palace lattice are connected to obtain the unlocking password 1234 (corresponding to the first identifier sequence).

It should be noted that, in this embodiment, the unlocking passwords of different applications may be different, that is, different applications in the electronic device may have different unlocking passwords (corresponding to the first identification sequence).

2) The electronic device is triggered to run the application 1 (for example, a user triggers an icon of the application 1 in a launcher interface of the electronic device), the electronic device presents the first identifier layout and detects the operation of the user, and an unlocking password (corresponding to the second identifier sequence) corresponding to an operation track of the user implementing the operation in the first identifier layout is obtained.

setting a first identifier sequence as abcd, when the electronic device selects a second identifier layout shown in fig. 3i as the first identifier layout and presents the second identifier layout, the user performs an operation shown by a dotted line in fig. 3i, the electronic device detects that an operating point of the operation forms a continuous track, the track between adjacent identifiers passed by the operating track in the first identifier layout is a straight line segment, and the operating track does not pass through a position corresponding to a different identifier in the first identifier sequence, and meets the preset condition, and identifiers sequentially triggered by the analyzed operating track in the first identifier layout are connected to obtain an unlocking password abcd (corresponding to the second identifier sequence) corresponding to the operating track operated by the user;

when the electronic device selects the second identifier layout shown in fig. 3j as the first identifier layout and presents the second identifier layout, the user may perform an operation shown by a dotted line in fig. 3j, the electronic device detects that the operation points of the operation form a continuous track, the track between adjacent identifiers passed by the operation track in the first identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, the preset condition is met, and identifiers sequentially triggered by the analyzed operation track in the third identifier layout are connected to obtain an unlocking password abcd (corresponding to the second identifier sequence) input by the user through the operation;

fig. 3h and fig. 3i both illustrate the first identifier layout arranged regularly, the first identifier layout may also adopt a first identifier layout arranged irregularly as shown in fig. 3k and fig. 3l, and if the first identifier sequence is abcd, the user may perform an operation shown by a dotted line in fig. 3j, an operation point of the electronic device detection operation forms a continuous track, a track between adjacent identifiers that the operation track passes through in the first identifier layout is a straight line segment, and the operation track does not pass through a position corresponding to a different identifier in the first identifier sequence, which meets the preset condition, and the identifiers sequentially triggered by the analyzed operation track in the third identifier layout are connected to obtain an unlocking password abcd (corresponding to the second identifier sequence) input by the user through the operation.

3) And matching the unlocking password (corresponding to the second identification sequence) input by the user with the preset password (corresponding to the first identification sequence), and responding to the operation based on the matching result.

When the unlocking password (corresponding to the second identification sequence) input by the user is matched with the preset unlocking password (corresponding to the first identification sequence), the electronic equipment releases the locking of the application 1, and at the moment, the application 1 can be operated and the interactive interface of the application 1 can be displayed on the display screen

Scenario 2) is also applicable to the process in which the electronic device is triggered to release specific content (e.g., multimedia content in the electronic device), and is not described herein again.

When the scheme of this embodiment is adopted to trigger unlocking processing, it seems to the observer that the user is performing a trajectory unlocking operation (that is, unlocking by using a specific trajectory) of the related art, but the user draws an operation trajectory corresponding to a preset unlocking password (corresponding to the first identifier sequence) through an operation to trigger unlocking, and because the first identifier layout is selected from at least two different second identifier layouts, when the first identifier layouts presented by the electronic device are different, the operation trajectories performed by the user in the different first identifier layouts and corresponding to the unlocking password (corresponding to the first identifier sequence) are also different, so that a possibility that the operation trajectory is recognized by the observer to trigger unlocking by using the operation trajectory is eliminated, and data security of the electronic device is ensured.

Example two

In this embodiment, a process of acquiring the second identification sequence in the first embodiment is further described in detail, and in the first embodiment, as shown in fig. 3g and 3h, fig. 3i and 3j, and fig. 3k and 3l, the operations have the following features:

1) the operating points of the operation form a continuous uninterrupted operating track;

2) the trajectory between any two adjacent marks triggered by the operation trajectory in the first mark layout is a straight line segment;

3) any two adjacent identifiers triggered by the operation track in the first identifier layout correspond to two adjacent identifiers in the first identifier sequence; that is, the first marker sequence does not have a marker in the corresponding distribution trace in the second marker layout that is different from the markers in the first marker sequence.

According to the above-mentioned features of the operations carried out in the first identification layout, as shown in fig. 4a, at least two different second identification sequences can be determined by:

at step 301a, at least two candidate tag layouts are generated.

Step 302a, for the candidate tag layout x, assigning the position in the candidate tag layout x to the tags in the first tag sequence until all the tags in the first tag sequence are assigned to the position in the candidate tag layout x.

The value of x is more than or equal to 2 and less than or equal to N, and N is the number of candidate mark layouts.

Step 303a, determining whether a trajectory formed by the first identifier sequence at the position of the candidate identifier layout x passes through a position, which is not allocated to the first identifier sequence, in the candidate identifier layout x, and if not, determining that the candidate identifier layout x is the second identifier layout, that is, selecting the presented candidate identifier layout x as the first identifier layout for the user to perform the operation, so as to determine the corresponding second identifier sequence (corresponding to the unlock password input by the user on the candidate identifier layout x) according to the detected operation trajectory (the operation has the above characteristics).

For example, assuming that the first identifier sequence is 1234, for the candidate identifier layout shown in fig. 4b, the track obtained by connecting 1 and 2 in the first identifier sequence needs to pass through the position where the identifier 5 in the candidate identifier layout is located, and therefore it is determined that the candidate identifier layout cannot be used as the second identifier layout, that is, the user cannot input identifiers 1 and 2 in the preset unlocking password (corresponding to the first identifier sequence) by operating and connecting through the candidate identifier layout shown in fig. 4 b.

It should be noted that, when the identifiers in the first identifier sequence are all different identifiers (for example, the first identifier sequence is 1234, that is, there is no identifier recurrence in the first identifier sequence, the distribution trajectory formed by the positions of the first identifier sequence in the candidate identifier layout x also needs to satisfy the condition that the distribution trajectory corresponding to the positions of the first identifier sequence in the candidate identifier layout is not intersected with the identifiers triggered by the distribution trajectory, so as to avoid the situation that the operation trajectory of the operation input by the user repeatedly triggers the same identifier and cannot identify the identifier.

For example, assuming that the first identifier sequence is 15463, for the candidate identifier layout shown in fig. 4c, the identifier 6 in the first identifier sequence and the identifier 6 that the identifier 3 has passed before the track in the candidate identifier layout passes through the track, so that the candidate identifier layout cannot be used as the second identifier layout, that is, the user cannot input the preset unlock password (corresponding to the first identifier sequence) by the candidate identifier layout shown in fig. 4 b.

The steps shown in fig. 4a can also be implemented by the steps shown in fig. 4d, which are equivalent in implementation effect, and are used to determine at least two different second tag layouts among the candidate tag layouts; as shown in fig. 4d, at least two different second identification sequences may also be determined by:

step 301b, N candidate tag layouts are generated, where N is an integer greater than or equal to 2.

The subsequent steps 302b and 303b are the processing of the candidate identified layout j.

Step 302b, placing the identifier i in the first identifier sequence at the position i of the candidate identifier layout j, placing the identifier i +1 in the first identifier sequence at the position i +1 of the candidate identifier layout j, wherein the position i and the position i +1 are different positions in the candidate layout j, the value of i is greater than or equal to 1 and less than or equal to M, M is the number of identifiers in the first identifier sequence, and the value of j is greater than or equal to 1 and less than or equal to N.

Step 303b, judging whether a track formed by the identifier i and the identifier i +1 passes through a position k in the candidate identifier layout j, wherein the position k is different from the position i and the position i + 1; and if not, judging that the candidate mark layout j is the second mark layout.

Similarly, for the case shown in fig. 4c, when the identifiers in the first identifier sequence are all different identifiers (for example, the first identifier sequence is 1234, that is, there is no repeated identifier occurrence in the first identifier sequence), the track formed by the positions of the identifier i and the identifier i +1 in the candidate identifier layout j in the first identifier sequence further needs to satisfy the following condition: the track formed by the positions of the identifier i and the identifier i +1 in the candidate identifier layout j is not intersected with the identifier passed by the track, namely the identifier m (m is smaller than i), so that the situation that the same identifier cannot be identified due to repeated triggering of the operation track which cannot identify the operation input by the user is avoided.

Embodiment three processing after successful or failed matching of the first identification sequence with the second identification sequence

The embodiment describes an information processing method, which can be applied to electronic devices such as smart phones and tablet computers; as shown in fig. 5, the information processing method according to the present embodiment includes the steps of:

in step 401, the electronic device presents a third identification layout.

Step 402, obtaining a first identification sequence based on the third identification layout.

The first identification sequence here can be used to authenticate access of the electronic device itself (e.g., when the electronic device is triggered to wake up from a hibernation state), to authenticate access of a specific application in the electronic device (e.g., an instant messaging application, an application presenting multimedia files local to the electronic device), or to authenticate access of specific content in the electronic device (e.g., multimedia content); that is, the user can trigger the electronic device to unlock itself, a specific application or specific content by inputting the first identification sequence to the electronic device.

In this embodiment, the first identifier sequence may not continuously have the same identifier, so as to avoid a situation that an operation trajectory corresponding to the first identifier sequence is drawn by an operation in the first identifier layout that cannot be presented by the electronic device subsequently, where the length of the first identifier sequence is smaller than the total number of the identified categories in the third identifier layout, for example, when the third identifier layout is a 9-squared figure in number 1, the length of the first identifier sequence may be smaller than the total number of the identified categories in the third identifier layout (9), and may also be equal to the total number of the identified categories in the third identifier layout (9).

At step 403, an instruction is received.

Step 404 presents a first identification layout.

for example, when the third identifier layout in the conventional form shown in fig. 3e is adopted (that is, the third identifier layout supporting the point-and-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in the regular arrangement shown in fig. 3i or fig. 3j may be selected as the first identifier layout to be presented; at the moment, the at least two second identifier layouts are different from the third identifier layout;

for another example, when the third identifier layout in the regular arrangement shown in fig. 3d is adopted (that is, the third identifier layout supporting the point-and-touch operation is used), the first identifier sequence is obtained, and when an instruction is subsequently received, one of the second identifier layouts in the regular arrangement shown in fig. 3d and fig. 3g can be selected as the first identifier layout to be presented, and at this time, one of the at least two second identifier layouts is the same as the third identifier layout;

the electronic equipment immediately determines at least two different second identifier layouts corresponding to the sequence 1 after acquiring the sequence 1, and only stores the sequence 2 after acquiring the sequence 2; when the electronic equipment receives an instruction to trigger unlocking of the electronic equipment (for example, the electronic equipment is triggered to light up the display screen from a dormant state), selecting one of at least two different predetermined second identifier layouts as a first identifier layout and presenting the first identifier layout on the display screen;

In step 405, an operation performed on a first logo layout is detected.

At step 406, the operation obtained based on the first identified layout is parsed.

Step 407, analyzing the identifiers sequentially triggered by the operation tracks in the first identifier layout, and obtaining a second identifier sequence based on the identifiers sequentially triggered by the operation tracks.

Step 408, detecting whether the second identification sequence is matched with the first identification sequence, and if so, executing step 409; otherwise, step 411 is executed.

In step 409, the lock is released upon matching.

And step 410, when the same instruction is received again, selecting a second identification sequence different from the most recently selected second identification sequence from at least two different second identification sequences as the first identification sequence to be presented.

For example, if the instruction received in step 403 is used to trigger unlocking of application 1, step 404 to step 407 are correspondingly executed, and if the obtained second identifier sequence (corresponding to application 1) matches the first identifier sequence, in step 408, a second identifier layout different from the second identifier layout selected in step 404 is selected from at least two different second identifier sequences (determined according to the first identifier sequence corresponding to application 1, which may be predetermined, or determined when the instruction triggering unlocking of application 1 is received for the first time) to be presented as the first identifier layout, so that the operation trajectories corresponding to the operations performed by the user in the first identifier layout each time are different, and the possibility of the trajectories recognized by a spectator is eliminated.

Step 411, selecting the second identifier layout selected from the at least two different second identifier layouts most recently (i.e. in step 404) as the first identifier layout, and returning to step 404 to present the first identifier layout, that is, when the second identifier sequence corresponding to the operation track performed by the user is not matched with the preset first identifier sequence, the first identifier layout presented most recently is still presented to detect the operation performed again by the user, and the second identifier sequence is re-determined based on the operation track and is matched with the first identifier sequence, but the first identifier layout is presented in a non-transformation manner, so that the possibility that the first identifier sequence is broken by the first identifier layout presented based on the transformation manner is avoided, and the security of the electronic device is further enhanced.

When the number of times that the second identification sequence is not matched with the first identification sequence exceeds the threshold value, the electronic device can refuse to respond to the instruction within the preset time so as to ensure the data security of the electronic device.
