Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
The term "module" as used herein may be considered a software object executing on the computing system. The various components, modules, engines, and services described herein may be viewed as objects implemented on the computing system. The apparatus and method described herein are preferably implemented in software, but may also be implemented in hardware, and are within the scope of the present invention.
The following is a detailed description of the analysis.
In the present embodiment, the hidden information display device will be described in terms of a hidden information display device, which may be integrated in a terminal, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for displaying hidden information according to an embodiment of the present invention. Specifically, the method comprises the following steps:
in step S101, an information display instruction is received.
The information refers to file information stored on the terminal, and can be pictures, short messages, address lists, call records, documents and the like.
In the process of using the terminal, the user checks private information stored in the terminal when the user uses the terminal, or deletes some important information by mistake when the user operates the terminal. The private information or important information on the terminal is hidden, and the hidden information is displayed only by inputting a password for verification when the user uses the terminal.
Based on this, when the user triggers the instruction of displaying the hidden information by the terminal, that is, the terminal is considered to receive the information display instruction, the triggering condition may be that a certain key on the terminal is clicked to enter a hidden information display verification mode (password verification mode), and this is not limited specifically here.
In a possible implementation manner, before receiving the information display instruction, the method further includes pre-collecting an angle value of the terminal relative to a horizontal plane, where the angle value may include 0 degree to 360 degrees. After gathering this angle value, carry out angle compensation to this angle value, if gather the angle value and be 90 degrees, can be through carrying out angle compensation to 90 degrees, with this angle value 90 degrees correspondence increase 10 degrees and reduce 10 degrees, the angle scope is predetermine for 80 degrees to 100 degrees in the generation, when the user needs show hidden information, need make the terminal place the angle value and be in this and predetermine the angle within range and verify, when the terminal is placed the angle value and is not in this and predetermine the angle within range, do not show hidden information.
It should be noted that, in the actual use of the terminal, due to the influence of various external factors, there is a certain error in the angle value that the user places each time uses the terminal, for example, when the user wants to input an angle value of 90 degrees, the user is likely to input 88 degrees or 92 degrees, and these errors are inevitable, so that the accuracy of the verification of the information can be ensured to a certain extent by performing angle compensation on the collected angle value and the generated preset angle range.
In step S102, the angle value of the terminal is acquired according to the information display instruction.
The angle value is an included angle formed by the terminal relative to a horizontal plane, and the horizontal plane is parallel to the ground plane.
Specifically, the obtaining of the angle value of the terminal according to the information display instruction includes:
(1) and generating a control signal according to the information display instruction.
The control signal is used for controlling a three-axis gravity sensor on the terminal to start.
It should be noted that the three-axis gravity sensor can calculate the inclination of the terminal with respect to the horizontal plane according to the acceleration induced by gravity.
Based on the method, after the terminal receives the information display instruction, a password verification mode is carried out, and a control signal is generated to control the three-axis gravity sensor on the terminal to start so as to obtain the angle value of the terminal.
(2) And acquiring an angle value of the terminal through a three-axis gravity sensor.
The angle value may be 0 degree to 360 degrees, specifically based on how the user is placed.
In a possible implementation manner, in order to avoid that the terminal happens to be just within the preset angle range when the user starts the verification, the verification result is inaccurate. Whether the current angle value of the terminal changes to a certain extent or not can be detected before the angle value of the terminal is obtained through the three-axis gravity sensor, and when the current angle value of the terminal changes to a certain extent, the angle value of the terminal is obtained through the three-axis gravity sensor. For example, when the terminal receives the information display instruction and performs password verification, at this time, it is detected whether the change of the angle value of the terminal exceeds a preset angle value (i.e., whether the user changes the placement angle of the terminal after the password verification of the terminal is started) through the three-axis gravity sensing, and when it is detected that the change of the angle value of the terminal exceeds the preset angle value (the user changes the placement angle of the terminal after the password verification of the terminal is started), the angle value of the terminal is started to be obtained.
In step S103, when it is determined that the angle value is within the preset angle range, the hidden information indicated by the information display instruction is determined.
Specifically, the determining of the hidden information indicated by the information display instruction may include:
(1) an initial time point is obtained.
(2) And starting calculation from the initial time point, and determining the hidden information indicated by the information display instruction when the angle value is judged to be always within the preset angle range in the preset time period.
It should be noted that, in order to avoid the situation that the user unintentionally places the angle value of the terminal within the preset angle range when performing password authentication, thereby causing the password to be authenticated by mistake. When the angle value of the terminal is judged to be within the preset angle range, an initial time point (starting timing) is obtained, and when the angle value is judged to be within the preset angle range all the time within the preset time period, the hidden information indicated by the information display instruction is determined (through password verification).
For example, when the terminal is determined to be within the preset angle range, time calculation is started, and when the terminal is determined to be within the preset angle range all the time within a preset time period (e.g., within 5 seconds), it is determined that password authentication is passed, and the hidden information indicated by the information display instruction is determined.
In step S104, the hidden information is subjected to a display operation.
The display operation is to display the hidden information in an editable state in a display interface of the terminal, and a user can perform operations such as viewing, copying, cutting, deleting and the like on the displayed hidden information.
In a certain possible implementation manner, the hidden information display method may also be applied to unlocking a terminal screen, when a screen unlocking instruction is received, the angle value of the terminal is obtained according to the screen unlocking instruction, and when it is determined that the angle value is within a preset angle range, a screen unlocking operation is performed, which is not specifically limited herein.
Therefore, according to the display method of the hidden information provided by the embodiment, when the information display instruction is received, the angle value of the terminal relative to the horizontal plane is obtained, and when the angle value is judged to be within the preset angle range, the hidden information is displayed, so that the problem that the user information is easy to steal is solved, and the safety of the user information is greatly improved.
The method described in the above embodiments is further illustrated in detail by way of example.
Referring to fig. 2, fig. 2 is another schematic flow chart of a method for displaying hidden information according to an embodiment of the present invention.
Specifically, the method comprises the following steps:
in step S201, an information display instruction is received.
In a possible implementation manner, before receiving the information display instruction, the method further includes pre-collecting an angle value of the terminal relative to a horizontal plane, where the angle value may include 0 degree to 360 degrees. After gathering this angle value, carry out angle compensation to this angle value, if gather the angle value and be 90 degrees, can be through carrying out angle compensation to this angle value 90 degrees, correspond to increase 10 degrees and reduce 10 degrees, the angle scope is predetermine to the formation and is 80 degrees to 100 degrees, when the user needs show hidden information, the angle value of placing that needs to make the terminal is in this and predetermines the angle within range and verify, when the terminal is not in this and predetermines the angle within range, will not show hidden information.
The information display instruction may be triggered and generated through a preset condition, for example, by clicking a physical key on the terminal or inputting human fingerprint and eye mask information, which is not specifically limited herein.
In step S202, the angle value of the terminal is acquired according to the information display instruction.
The angle value is an included angle formed by the terminal relative to a horizontal plane, and the horizontal plane is parallel to the ground plane.
Specifically, the obtaining of the angle value of the terminal according to the information display instruction includes:
(1) and generating a control signal according to the information display instruction.
The control signal is used for controlling a three-axis gravity sensor on the terminal to start.
Specifically, after the terminal receives the information display instruction, a password verification mode is performed, and a control signal is generated to control a three-axis gravity sensor on the terminal to start so as to obtain an angle value of the terminal.
(2) And acquiring an angle value of the terminal through a three-axis gravity sensor.
The angle value may be 0 degree to 360 degrees, specifically based on how the user is placed.
In a possible implementation manner, before the obtaining of the angle value of the terminal by the three-axis gravity sensor, whether a certain change occurs in the current angle value of the terminal may be further detected. And when the current angle value of the terminal is detected to be changed to a certain extent, the angle value of the terminal is obtained through the three-axis gravity sensor. For example, when the terminal receives the information display instruction and performs password verification, at this time, it is detected whether the change of the angle value of the terminal exceeds a preset angle value (i.e., whether the user changes the placement angle of the terminal after the password verification of the terminal is started) through the three-axis gravity sensing, and when it is detected that the change of the angle value of the terminal exceeds the preset angle value (the user changes the placement angle of the terminal after the password verification of the terminal is started), the angle value of the terminal is started to be obtained.
In step S203, it is determined whether the angle value is within a preset angle range.
If the angle value is within the preset angle range, executing step S204; if the angle value is not within the preset angle range, step S209 is executed.
Specifically, the preset angle range is generated by performing a certain preset angle compensation on a preset angle input by the user, and if the preset angle input by the user is 90 degrees, the preset angle value is 10 degrees. Then, the preset angle range is determined to be between 80 degrees of 90 degrees minus 10 degrees and 100 degrees of 90 degrees plus 10 degrees, and when the angle value of the current terminal is determined to be 85 degrees, the terminal is determined to be in the preset angle range.
In step S204, an initial time point is acquired.
In step S205, when it is determined that the angle value is always within the preset angle range within the preset time period from the initial time point, the hidden information indicated by the information display instruction is determined.
It should be noted that, during the verification process, the user may put the angle value of the terminal in the preset angle range unconsciously, which may cause a false verification.
Based on the method, when the angle value of the terminal is judged to be within the preset angle range, the current time point is obtained, and timing is started. When the angle value of the terminal is judged to be always within the preset angle range within the preset time period, analyzing the information instruction, and determining the hidden information indicated by the information instruction, for example, when the angle value of the terminal is judged to be 85 degrees and is judged to be within the preset angle range, acquiring an initial time point (such as 18:10:08), starting timing, continuously detecting the angle value of the terminal within the preset time period (such as 10 seconds), and when the angle value of the terminal is always within the preset angle range within the preset time period (the terminal placing angle value is detected to be always between 80 degrees and 100 degrees), judging that the verification is passed, and determining the hidden information indicated by the information display instruction. And when the angle value of the detection terminal is not always within the preset angle range (the angle value of the detection terminal is not always between 80 degrees and 100 degrees), judging that the verification fails, and restarting to acquire the angle value of the terminal.
In step S206, the hidden information is subjected to a display operation.
The display operation is to display the hidden information in an editable state in a display interface of the terminal, and a user can perform operations such as viewing, copying, cutting, deleting and the like on the displayed hidden information.
In a possible implementation manner, after the information display instruction is detected to be received, timing is started, and if the terminal does not perform display operation on the hidden information within a preset time (that is, the hidden information is not verified by the password), the terminal stops responding to the information display instruction. For example, after the terminal receives the information display instruction, a password verification mode is performed to obtain a current angle value of the terminal, timing is started, if the terminal fails to pass the password verification within 2 minutes (the terminal does not perform display operation on hidden information), the password verification is stopped, and the information display instruction is not responded within a certain time, so that a non-user himself is prevented from cracking the password.
In step S207, a preset angle update rule is acquired.
In step S208, the preset angle range is updated based on the preset angle update rule.
It should be noted that, if the preset angle range is always unchanged, the rule is easily seen by a nearby person in the verification process, so that the preset angle range is updated after each display operation according to the preset angle update rule, so as to increase the safety of the preset angle range.
Here, the preset angle updating rule may be an inverse number of the preset angle range or a preset periodic angle value added, and for better explanation of the embodiment, the preset angle updating rule is taken as an inverse number.
Based on the above, after the hidden information is displayed, the terminal updates the preset angle range according to the preset angle updating rule. And if the original preset angle range is between 80 and 100 degrees, updating by taking the preset angle updating rule as an inverse number to obtain a new preset angle range between-80 and-100 degrees, and by analogy, after the next hidden information display operation is performed by taking the preset angle range between-80 and-100 degrees, updating the preset angle range between 80 and 100 degrees.
In a possible embodiment, after the displaying the hidden information, hiding the displayed hidden information when detecting that the information quitting instruction is received is further included.
The information exit instruction can be generated for exiting the current information display interface operation and the terminal screen locking operation.
In step S209, the response to the display operation of the hidden information is rejected.
When the angle value of the terminal is judged not to be within the preset angle range, the terminal refuses to respond to the display operation of the hidden information for the illegal display operation of the user, so that the current user cannot view the hidden information, and the safety of the information is protected.
In order to better describe the embodiment of the present invention, the hidden interface schematic diagram shown in fig. 3, the terminal placement scene schematic diagram shown in fig. 4, and the display interface schematic diagram shown in fig. 5 are used to describe in detail: in the practical use of the mobile phone, in order to prevent other people from looking at the private information stored on the mobile phone when using the mobile phone, the user can hide some private information or important information on the mobile phone, and the hidden information is displayed only after the user passes the password verification. When the important information is set and hidden, a preset angle range (preset verification password) input by a user needs to be collected in advance, the preset angle range is a preset angle value (such as 60 degrees) set by the user, angle compensation is carried out according to the preset angle value of 60 degrees, 10 degrees are correspondingly increased and 10 degrees are correspondingly reduced, and the generated preset angle range is 50 degrees to 70 degrees.
As shown in fig. 3, when a user enters the interface of the mobile phone album, since the picture information in the album is hidden information preset by the user, when the user enters the album, the displayed latest picture a and the displayed picture B are both 0. At the moment, a user can trigger and generate an information display instruction by continuously clicking a volume adjusting key on the mobile phone, when the user double-clicks the volume adjusting key, the mobile phone receives the information display instruction, pops up a prompt text box A, prompts the user to input a verification password, generates a control signal, and starts a three-axis gravity sensor in the mobile phone according to the control signal. In order to prevent a user from detecting whether a current angle value of the mobile phone changes to a certain extent when the user starts authentication, when the current angle value of the mobile phone changes to a certain extent, the angle value of the terminal is obtained through the three-axis gravity sensor (password authentication is started), for example, when the mobile phone receives an information display instruction and pops up a text box, the placement angle of the mobile phone is 55 degrees, the 55 degrees are invalid angle values, only when the angle of the mobile phone changes to a certain extent, the change value can be 20 degrees, namely, when the angle of the mobile phone is detected to be out of the range of 35 degrees to 75 degrees, the valid angle value is obtained, namely, the password authentication is started.
As shown in fig. 4, the user sets the placement position of the mobile phone to find that the angle value with respect to the ground plane is 60 degrees, and the angle value is determined to be within the preset angle range of 50 degrees to 70 degrees. And acquiring the current system time of the mobile phone, supposing that the system time is 18:10:08, calculating from the time point, and judging that the hidden picture information in the hidden interface is acquired through password verification when the angle value of the mobile phone is always within the preset angle range of 50-70 degrees within 10 seconds, namely before 18:10: 18.
As shown in fig. 5, the mobile phone performs a display operation on the acquired hidden picture information, where the latest picture a on the display interface is changed from 0 to 50, and the picture B is changed from 0 to 100, at this time, the user may perform operations of viewing, copying, cutting, and deleting on the displayed latest picture and picture. After the display operation, a preset angle updating rule is obtained (the preset angle range is subjected to inverse counting), the preset angle range is updated according to the preset angle updating rule, the updated preset angle range is generated to be-50-70 degrees, and at the moment, if the condition that the user exits from the current display interface or the screen locking operation is detected, the displayed hidden information is hidden.
It should be noted that, after the mobile phone receives the information display instruction and pops up the prompt text box a, if the user cannot pass the password verification all the time (e.g., within 2 minutes), the mobile phone performs the screen locking operation, and does not receive the information display instruction within a preset time (e.g., within 10 minutes).
Therefore, the hidden information display method provided by the embodiment includes the steps that when an information display instruction is received, the angle value of the terminal relative to the horizontal plane is obtained, when the angle value is judged to be within the preset angle range, the initial time point is obtained, when the angle value is always within the preset angle range within the preset time period, the hidden information is displayed and operated, the preset angle range is updated according to the preset angle updating rule, the problem that user information is easy to steal is solved, and the safety of the user information is greatly improved.
In order to better implement the method for displaying hidden information provided by the embodiment of the present invention, an embodiment of the present invention further provides a device based on the method for displaying hidden information. The meaning of the noun is the same as that in the above-mentioned display method of the hidden information, and the specific implementation details can refer to the description in the method embodiment.

And when the current angle value of the terminal is detected to be changed to a certain extent, the angle value of the terminal is obtained through the three-axis gravity sensor. For example, when the terminal receives the information display instruction and performs password verification, at this time, it is detected whether the change of the angle value of the terminal exceeds a preset angle value (i.e., whether the user changes the placement angle of the terminal after the password verification of the terminal is started) through the three-axis gravity sensing, and when it is detected that the change of the angle value of the terminal exceeds the preset angle value (the user changes the placement angle of the terminal after the password verification of the terminal is started), the angle value of the terminal is obtained through the angle obtaining sub-module 322.
The determining module 33 may further include an initial obtaining sub-module 331 and a determining sub-module 332.
Specifically, the initial obtaining sub-module 331 is configured to obtain an initial time point when the angle value is determined to be within the preset angle range. The determining submodule 332 is configured to start calculation from the initial time point, and determine hidden information indicated by the information display instruction when it is determined that the angle value is always within the preset angle range within the preset time period.
When the initial obtaining sub-module 331 determines that the angle value of the terminal is within the preset angle range, the current time point is obtained, the timing is started through the determining sub-module 332, and when the angle value of the terminal is determined to be within the preset angle range within the preset time period, the information instruction is analyzed, and the hidden information indicated by the information instruction is determined. For example, when the angle of the terminal is determined to be 85 degrees and is determined to be within the preset angle range of 80 degrees to 100 degrees, an initial time point (e.g., 18:10:08) is obtained, timing is started, the angle value of the terminal is continuously detected within a preset time period (e.g., 10 seconds), and when the angle value of the terminal is always detected to be within the preset angle range within the preset time period (it is detected that the placement angle value of the terminal is always within 80 degrees to 100 degrees), it is determined that verification is passed, and the hidden information indicated by the information display instruction is determined.
And a rule obtaining module 35, configured to obtain a preset angle update rule.
And an updating module 36, configured to perform an updating operation on the preset angle range based on the preset angle updating rule.
The preset angle updating rule in the rule obtaining module 35 may be an inverse number of the preset angle range or a preset periodic angle value added, and for better explaining the present embodiment, the preset angle updating rule is taken as an inverse number for example.
Based on this, after the display module 34 performs the display operation on the hidden information, the update module 36 performs the update operation on the preset angle range according to the preset angle update rule. And if the original preset angle range is between 80 and 100 degrees, updating by taking the preset angle updating rule as an inverse number to obtain a new preset angle range between-80 and-100 degrees, and by analogy, after the next hidden information display operation is performed by taking the preset angle range between-80 and-100 degrees, updating the preset angle range between 80 and 100 degrees.
And a hiding module 37, configured to hide the displayed hidden information when it is detected that the information quitting instruction is received.
The information exit instruction in the hidden module 37 may be generated for exiting the current information display interface operation and the terminal screen locking operation.
By the above, the display device of hidden information that this embodiment provided, through when receiving the information display instruction, obtain the angle value of terminal for the horizontal plane, when judging that this angle value is in predetermineeing the angle within range, obtain the initial time point, when angle value is in predetermineeing the angle within range all the time in predetermineeing the time quantum, will hide the information and show the operation, and update the operation with predetermineeing the angle update rule to predetermineeing the angle range, the condition that user information is easily stolen has been solved, very big promotion user information's security.
