Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a method for protecting user privacy according to an embodiment of the present invention. The method may be performed by an apparatus for protecting user privacy, wherein the apparatus may be implemented by software and/or hardware, and may be generally integrated in a mobile terminal. The method may comprise the steps of:
and step 110, acquiring touch operation of the user on the virtual keyboard in the application program.
The virtual keyboard may be an input control displayed on the touch screen for a user to input information to the terminal. For example, the virtual keyboard may include a dial of a telephone application, a keyboard in a WeChat or SMS application, and the like.
The touch operation may be a click operation on a virtual keyboard displayed on the touch screen. For example, the touch operation may be a click operation on a number on a dial in a phone application. For another example, the touch operation may be a click operation on an english character in the virtual keyboard in the english mode of WeChat.
The method comprises the steps of obtaining an application program of the mobile terminal in a running state at present, monitoring the application program located at the top of a task stack, and determining whether a user touches a virtual keyboard in the application program. The application program may be a phone application or a short message application pre-configured in the mobile terminal, or may be a third party application installed by the user.
Further, the white list may be preconfigured. And when the application in the set white list is started, starting a privacy protection mode. The white list may be a collection of applications that need to be protected from user privacy, and the applications that are white listed may be permitted to perform operations that protect user privacy under certain circumstances. There are many ways to determine the white list, for example, by configuring an application program, which may relate to user privacy information, as a white list by a terminal manufacturer and presetting the white list in the mobile terminal. For another example, when the user starts to use the mobile terminal, the user first enters a privacy protection function setting interface to prompt the user to select an application program needing privacy protection, and the white list is updated according to the application program selected by the user. For example, the white list may include a phone application, a WeChat or SMS application, and the like. Specifically, when some services are handled by dialing a telephone, privacy information such as a personal identification number of a user needs to be input, and real information can be hidden when the user inputs the privacy information through the user privacy protection function. For another example, the user may need to send privacy information such as a personal identification number through WeChat or short message sometimes, and the real information can be hidden when the user inputs the privacy information through the user privacy protection function.
On the basis of the above optimization scheme, before obtaining the touch operation of the user on the virtual keyboard in the application program, the method further includes: judging whether the application program running in the foreground belongs to a pre-configured white list or not; when the application program running in the foreground belongs to the white list, a privacy protection mode is started; the privacy protection mode is a mode for hiding real characters input by a user.
Illustratively, the application program currently in the running state of the mobile terminal is obtained, and the package name of the application program positioned at the top of the task stack is determined. And inquiring a pre-configured white list according to the packet name, and determining whether the application program operated by the foreground of the current mobile terminal belongs to the white list. And monitoring the touch operation of the virtual keyboard input by the user in the current application program when the application program belongs to the white list. Specifically, taking a capacitive touch screen as an example, when a finger touches a metal layer, due to an electric field of a human body, a coupling capacitor is formed between a user and the surface of the touch screen, for a high-frequency current, the capacitor is a direct conductor, so that the finger sucks a very small current from a contact point, the currents respectively flow out from electrodes on four corners of the touch screen, the currents flowing through the four electrodes are in direct proportion to distances from the finger to the four corners, and a controller obtains a contact point coordinate of the touch point through accurate calculation of the proportions of the four currents. And determining whether the touch operation is the operation on the virtual keyboard according to the touch point coordinates corresponding to the touch operation.
And step 120, determining a user input character string according to the touch operation, and judging whether the user input character string meets a preset rule.
The preset rule is that the character string input by the user comprises a setting character string, wherein the setting character string comprises at least two continuous setting characters. For example, if the user preset character string is 44528, the mobile terminal determines that the user input character string includes the preset character string when detecting the user input 44528.
Specifically, when the touch operation of the user is a touch operation on a virtual keyboard in an application program running in the foreground of the current terminal, the character string input by the user is determined according to the touch point coordinates corresponding to the touch operation. Judging whether the character string length of the character string input by the user is not less than the character string length of the set character string, and determining whether to execute the operation of judging whether the character string input by the user accords with the preset rule or not according to the judgment result. For example, when the length of the character string of the user input character string is smaller than the set character string, the comparison operation between the user input character string and the set character string may not be executed, so as to save the terminal processing flow and improve the terminal processing efficiency. And when the character string length of the user input character string is the same as that of the set character string, judging whether the user input character string is the same as the set character string, if so, determining that the user input character string accords with a preset rule, otherwise, determining that the user input character string does not accord with the preset rule. When the length of the character string input by the user is larger than the set character string, starting from a character corresponding to the tail of the character string input by the user, selecting a continuous character sub-string with the same length as the character string of the set character string in the character string input by the user, judging whether the character sub-string is the same as the set character string or not, if so, determining that the character string input by the user accords with a preset rule, otherwise, determining that the character string input by the user does not accord with the preset rule.
And step 130, when the user input character string conforms to a preset rule, taking the user input character at the next moment as an initial character, and starting from the initial character, displaying by adopting a preset target character to replace the user input character.
The terminal can determine the moment when the character string input by the user meets the preset rule as the current moment, and if the user performs touch operation on the virtual keyboard at the next moment, the touch point coordinate corresponding to the touch operation is acquired. Thus, the character input by the user at the next moment is determined according to the touch point coordinates, and the character is taken as a starting character.
The target characters may be one character (e.g., &) or a different plurality of characters (e.g., &, ￥,%. to sequentially acquire one of the plurality of characters) and, in particular, a target character list may be preset in which a plurality of target characters for replacing the user input information are stored.
For example, when a user transacts a specific service through a mobile terminal, the user needs to input a personal identification number, the user sets a set number of characters in the personal identification number as a set character string in advance, in the process of inputting the personal identification number according to a voice prompt of the specific service, the terminal compares the user input character string with the set character string in real time, when the user input character string includes the set character string, a target character (a character other than a terminator or a character having other specific meanings) is displayed at a set position on a touch screen instead of an actual character input by the user, fig. 2 shows a schematic view of a dialing interface provided by an embodiment of the present invention, as shown in fig. 2, the user input character string includes the set character string 201 for hiding a target character 202 and a termination character 203 of a real user input character, specifically, when it is detected that the user input character string includes the set character string 44528, a character input from the user again after the number "8" is displayed on the touch screen, a query list of the target character string is displayed on the touch screen instead of a query list of a target character, and then a query list of the user is displayed on the touch screen, when it is detected that the user input character string includes the target character string 449, the target character list of a query number No. 528, and the target character list of a query No. 4 is displayed on the touch screen, the target character list of the user is displayed on the touch screen, if a query No. 2.
Further, upon detecting a termination character input by the user, the user input character is displayed starting from the termination character. Wherein the termination character may be a character that identifies termination of employing the target character in place of the user input information. The termination character can be determined in various ways, for example, a user-defined character can be used as the termination character. For another example, the terminal manufacturer may count the commonly used termination characters and pre-configure the termination characters in the mobile terminal.
According to the technical scheme, the touch operation of the user on the virtual keyboard of the application program in the currently running set white list is obtained, the user input character string is determined according to the touch operation, whether the user input character string meets the preset rule or not is judged, when the user input character string meets the preset rule, the user input character at the next moment is used as the initial character, the character string from the initial character to the set termination character is displayed by adopting the preset target character, the user privacy information is hidden, and the user privacy information can be prevented from being peeped by others. The embodiment solves the problem that the user information security is possibly threatened because the user inputs the personal privacy information and is easy to be peeped by others at present, and achieves the effect of improving the information security of the terminal user and the management efficiency of the mobile terminal.
Preferably, when the user input character string conforms to a preset rule, the real character of the virtual keyboard in the English input state or the digital input state is displayed by adopting a replacement character corresponding to the real character. The method has the advantages that the characters displayed on the virtual keyboard are replacement characters which are preset by the user and correspond to the real characters, so that the situation that other people steal personal privacy information of the user by peeping the operation of the user on the virtual keyboard is avoided, and the information safety of the user is further guaranteed.
Fig. 3 is a flowchart of another method for protecting user privacy according to an embodiment of the present invention. As shown in fig. 3, the method may include:
and 310, when the application program in the white list is set to be in the running state, acquiring the touch operation of the user on the virtual keyboard in the application program.
And when the privacy protection event trigger is detected, executing the user privacy protection function. For example, in the process of detecting that the user dials a call, the user is prompted by voice to input a personal identification number, a query password or a bank reserved mobile phone number, and the like, a privacy protection event is triggered. Alternatively, when a WeChat or a short message is detected, and a user inputs a key word such as an identity card number, a user name or a password for logging in a set application program, and the like, a privacy protection event is triggered. Taking the example that a user transacts a specific service through a mobile terminal, when detecting that the voice prompts the user to input a personal identification number, a privacy protection event is triggered to detect whether an application program currently running in the foreground of the terminal is an application program in a set white list.
For example, taking a mobile terminal equipped with an android system as an example, a running process of the system may be obtained by calling a getringing appprocesses () method in an ActivityManager class. And then, judging whether the application program corresponding to the process is positioned at the stack top of the task stack. A task stack is a container with a stack structure that can hold multiple Activity instances. An Activity is an application component that provides a screen through which a user can interact with the terminal to perform some task, such as dialing numbers, taking pictures, sending emails, looking at maps, etc. When an application is launched, the system creates a task (task) for the application to place the root Activity of the application. And when the application program corresponding to the process is positioned at the top of the stack, inquiring a set white list according to the packet name of the application program, and determining whether the application program belongs to the set white list.
And if the application program belongs to the set white list, acquiring the touch operation of the user. Specifically, the touch screen adopted by the existing mobile terminal includes a resistive touch screen, a capacitive touch screen, a piezoelectric touch screen, and the like, and when a user touches the touch screen, the touch screen can detect touch information, and then the touch operation of the user is identified. Taking a capacitive touch screen as an example, the touch screen can sense the change of capacitance, when a user touches the touch screen, the touch screen senses the change of capacitance and recognizes touch information, the touch information comprises an x coordinate and a y coordinate, and the coordinate information is reported to an upper layer through an input system, so that the touch operation occurring at a certain position of the touch screen can be determined by using the touch information.
Since the display position of the virtual keyboard of the application program is known, it can be determined whether the touch operation is a touch operation on the virtual keyboard in the application program according to the x coordinate and the y coordinate of the touch point corresponding to the touch operation.
And step 320, determining a character string input by the user according to the touch operation.
When the touch operation is the touch operation on the virtual keyboard in the application program, determining which characters on the virtual keyboard correspond to the touch operation according to the x coordinate and the y coordinate of the touch point corresponding to the touch operation, and accordingly determining that a user inputs a character string.
Step 330, determining whether the string length of the user input string is not less than the string length of the set string, if yes, executing step 340, and if no, executing step 320.
If the string length of the user input string is smaller than the string length of the set string, step 320 is executed. Specifically, if the user inputs the character string "445" whose length is smaller than the length of the setting character string "4528", step 320 is executed. If the terminal executes step 320 to detect that the user inputs "2", in this case, the user inputs "4452" as the character string, and the length of the character string is equal to the length of the set character string, execute step 340.
Step 340, determining whether the user input character string meets a preset rule, if yes, executing step 350, and if not, executing step 320.
Fig. 4 is a flowchart of a method for determining whether a character string input by a user meets a preset rule according to an embodiment of the present invention. As shown in fig. 4, the method may include:
step 341, comparing the character string length of the character string input by the user with the character string length of the set character string.
The setting character string may be located at a head position of the user input character string, and may also be located at a middle position of the user input character string. For example, the setting string may be "44528" or "4528".
Step 342, determine whether the two strings have the same length, if yes, go to step 343, otherwise go to step 344.
Step 343, comparing the character string input by the user with the set character string.
For example, when the user input character string is "44528" and the setting character string is also "44528", the user input character string is compared with the setting character string, and since the characters included in the two character strings are completely the same, it is determined that the user input character string meets the preset rule, and the process goes to step 350.
For example, when the user inputs "4452" as the character string and "4528" as the setting character, the character string length is the same as the character string length of the setting character string. Then, the user input character string "4452" is compared with the setting character string "4528" to determine whether the characters included in the two character strings are identical, and thus, whether the user input character string conforms to a preset rule is determined according to the comparison result. In this example, the two character strings of the user input character string and the setting character string do not include exactly the same characters, and because the length of the character string of the user input character string is not greater than the setting character string, it is determined that the user input character string does not conform to the preset rule, and the step 320 is returned to.
And 344, starting from the character corresponding to the tail of the character string input by the user, selecting a continuous character sub-string with the same length as the character string of the set character string in the character string input by the user.
When the user inputs the character string as "44528", the character string length is larger than the character string length of the setting character string. Starting with the character "8" corresponding to the end of the user input character string, a character sub-string having the same character string length as the set character string "4528" is selected from the user input character string, and the execution proceeds to step 345, where the character sub-string is "4528".
Step 345, comparing the character sub-string with the set character string.
Illustratively, the character sub-string "4528" is compared with the set character string "4528" to determine whether the two character strings include identical characters. Because the two character strings of the character sub-string and the set character string comprise the same characters, the user input character string is determined to accord with the preset rule, and the step 350 is executed.
And 350, displaying the real characters of the virtual keyboard in an English input state or a digital input state by adopting the replacing characters corresponding to the real characters.
The corresponding relation between the replacing character and the real character is preset by the user. For example, after entering the privacy protection function setting interface and setting a white list by the user, the user may be prompted to set a replacement character of the real character, and a character replacement table may be generated. For example, the character substitution table may be as shown in table 1:
table 1 is a character substitution table of real characters and substitution characters
When the user input characters accord with the preset rules, the preset replacement characters of the real characters are displayed on the virtual keyboard in the English input state or the digital state. Fig. 5 is a schematic diagram illustrating another dialing interface provided by an embodiment of the invention. As shown in fig. 5, the terminal displays the real characters 0-9 in the dial by using corresponding replacement characters.
Illustratively, if the user further needs to input 199012116022 after inputting 44528 and ends with # and the replacement character is displayed on the virtual keyboard, the user needs to input azztaaatcpp # and the characters displayed on the display screen are 44528& & & & & & & & & & & & & & & & & & &. The design has the advantages that even though the user is peeped by others when inputting the privacy information, the user privacy information can be protected from being leaked because the replacement characters of the real characters are displayed in the virtual keyboard, and the real characters actually input by the user are not clear to others.
