Background

The input method is a necessary tool for a user to input characters into the terminal, runs on an operating system carried by the terminal, and can convert codes input by a keyboard or media data input by other non-keyboards into characters. At present, the input method can be divided into keyboard input and non-keyboard input, wherein the technology is the most mature, and the most widely used input method is the input method based on keyboard input.

The input method based on keyboard input is a method for inputting characters according to a certain coding rule by using a keyboard, when a user inputs the characters for the first time by using the input method in an application program, considering that the same characters may be input by the user for the next time, the input method often records other characters which are continuously input by the current user after the characters are input by the user, takes the other characters as candidate words of the characters, and displays the generated candidate words by using the input method until the character is input again by the user for the next time, so that the workload of the user for inputting the same characters and candidate words by using the keyboard can be reduced.

In carrying out the present disclosure, the disclosure finds at least the following problems with the related art:

when a user uses application programs related to personal privacy, such as a bank client, a payment tool client and the like, the user needs to input a related account number, a user name, a password and the like in an input box of the application programs, because an input method provides a candidate word function for the user, a number or a letter is sometimes input, and a candidate word used by the user before is displayed, and because the candidate words may relate to the personal privacy of the user, the security of the client is reduced, and the client has certain risks.

hiding the target candidate words, and displaying the second candidate words except the target candidate words in the at least one first candidate word and the at least one second candidate word.

All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.

Fig. 2 is a flowchart illustrating a candidate word display method according to an exemplary embodiment, and the method is applied to a terminal, as shown in fig. 2, and includes the following steps.

In step 201, the terminal queries the first lexicon and the second lexicon respectively based on the input characters of the user in the input box of the application program to obtain at least one first candidate word and at least one second candidate word.

In the embodiment of the disclosure, the input box belongs to one of interface views in an operating system carried by a terminal, and each interface view corresponds to one identifier in the operating system, so the input box also has an input box identifier, and the input box identifier can be used for distinguishing input boxes of different applications or different functions of the system. The terminal provides an input box display inlet in the page of the application program, when a user needs to input characters in the application program, the input box display inlet is clicked, the terminal calls the input box of the application program in the operating system, and therefore the user can input the characters in the input box. When the input characters of the user are displayed in an input box of the application program, the terminal queries a first word bank based on the input characters to obtain at least one first candidate word; and then, querying a second word bank based on the input characters to obtain at least one second candidate word.

The first word stock is a core word stock applied by an operating system or an input method carried by the terminal, that is, the first word stock stores candidate words preset by a user, which are input methods currently running in the operating system carried by the terminal; thus, at least one first candidate word obtained in the first word bank is a candidate word preset for the user by the input method. The second word bank is used for storing words accumulated in the history input process of the user in the application program, namely candidate words recorded according to the input habits of the user. Thus, at least one second candidate word obtained in the second word bank is the word accumulated by the user in the history input process. For example, if the user has input the name "zhang san", the terminal takes "zhang san" as the second candidate word and stores it in the second lexicon, so that when the user inputs "zhang san" next time, the terminal will obtain the second candidate word "zhang san" in the second lexicon and display it to the user. It should be noted that the first lexicon and the second lexicon can be two different lexicons respectively, and can also be the same lexicon; and if the first word bank and the second word bank are the same word bank, at least one first candidate word and at least one second candidate word are respectively stored in different directories in the word bank.

For example, if the user has input the complete identification numbers "5201401987 xxxxxxxxxx" and "5201431993 xxxxxxxx" in the input box of the application, the terminal stores "5201401987 xxxxxxxxxx" and "5201431993 xxxxxxxxxx" as the second candidate word in the second thesaurus. When the input character of the user in the input box of the application program is '520', at least one first candidate word obtained by the terminal inquiring the first word bank can be a candidate word preset by an input method, such as 'I love you', '521', and the like; the at least one second candidate word from the second thesaurus may be "5201401987 xxxxxxxx", "5201431993 xxxxxxxx", etc.

In step 202, the terminal detects a current input environment, and if the current input environment is determined to be an abnormal environment, step 203 is executed; if the current input environment is determined to be a normal environment, step 204 is executed.

In order to ensure that the second candidate word is hidden in the abnormal environment to ensure the security of the privacy of the user, the terminal detects the current input environment before displaying the candidate words. When detecting the current input environment, the terminal may adopt at least one of the following three methods:

the method comprises the steps that a terminal determines the account type of a current login account in an application program, and if the current login account is a common account, the current input environment is determined to be a normal environment; and if the current login account is a private account, determining that the current input environment is an abnormal environment.

The inventors have realized that the security and privacy requirements may be different for different accounts involved in an application and that the user may wish to display different candidate words. For accounts that involve personal privacy such as assets, identification numbers, etc., the user may not need to display the second candidate word; for some accounts that do not involve personal privacy, the user may need to display the second candidate word for convenience, so the terminal may detect the input context based on the login account to determine how to display the candidate word.

In the embodiment of the present disclosure, the account types at least include a normal account and a private account, and the terminal may determine the account type of the currently logged-in account according to the password type of the account, the primary and secondary accounts (e.g., the primary account or the secondary account) of the account, the function of the account, and the like. The method includes the steps that a terminal determines the account type of a current login account according to the password type of the account. The terminal provides passwords with different forms such as digital passwords, pattern passwords, face passwords, fingerprint passwords and the like for the account, the passwords with different forms correspond to different account types, and the account is set to be a common account or a private account according to the password form set for the account by the user. If the current login account is determined to be a common account according to the password form, determining that the current input environment is a normal environment; and if the current login account is determined to be the private account according to the password form, determining that the current input environment is the abnormal environment.

For example, if the user sets a digital password for account a and sets a fingerprint password for account B, the terminal sets account a as a normal account and sets account B as a private account.

Continuing to take the above situation as an example, because the terminal provides a digital password for the common account and a fingerprint password for the private account, when the terminal determines the type of the account currently logged in the application program, if the password form of the currently logged account is the digital password, it can be determined that the currently logged account is the common account, that is, it is determined that the current input environment is the normal environment; if the password form of the current login account is the fingerprint password, the current login account can be determined to be a private account, namely the current input environment is determined to be an abnormal environment.

If the terminal determines the account type of the account according to the primary account and the secondary account, the terminal can set the primary account as a private account and the secondary account as a common account. Thus, if the terminal determines that the current login account is the slave account, the current input environment is determined to be the normal environment; and if the terminal determines that the current login account is the main account, determining that the current input environment is an abnormal environment.

If the terminal determines the account type of the account according to the account function, the terminal can use the account with the payment function as a private account and use the account without the payment function as a common account. Thus, if the terminal determines that the currently logged account does not have the payment function, the current input environment is determined to be a normal environment; and if the terminal determines that the currently logged account has the payment function, determining that the current input environment is an abnormal environment.

The second method comprises the steps that the terminal sends a connection request to the preset wearable device, and if a connection response of the preset wearable device is received, the current input environment is determined to be a normal environment; and if the connection response of the preset wearable device is not received, determining that the current input environment is an abnormal environment.

The inventor realizes that for common wearable devices such as a bracelet and a watch, a user can wear the wearable device frequently, and the terminal can determine whether the terminal is currently held by an actual user or not by connecting the wearable device so as to determine the current input environment, so that the terminal can adopt the following method for detecting the current input environment.

In the embodiment of the present disclosure, the preset wearable device may be a common wearable device of a user such as a bracelet and a watch. When the user sets wearing equipment commonly used as preset wearing equipment, the terminal can acquire the equipment identifier of the wearing equipment commonly used, and the equipment identifier of the wearing equipment commonly used is stored to serve as the equipment identifier of the preset wearing equipment. When a user calls an input box in an operating system according to the user requirement, the terminal sends a connection request to the preset wearable device according to the device identification of the preset wearable device; if the terminal receives a connection response of the preset wearable device, determining that the current input environment is a normal environment; and if the terminal does not receive the connection response of the preset wearable device, determining that the current input environment is an abnormal environment.

The terminal can be implemented by bluetooth, WI-FI (wireless fidelity, wireless network) and the like when sending a connection request to the preset wearable device.

If the terminal sends a connection request to the preset wearable device through the Bluetooth, the terminal and the preset wearable device both need to start the Bluetooth function. After the terminal sends a connection request to the preset wearable device through Bluetooth, if the preset wearable device sends a connection response to the terminal device, connection can be established between the preset wearable device and the terminal, and therefore the terminal can determine that the current input environment is a normal environment; if the distance between the preset wearable device and the terminal exceeds the connection range or the terminal is in an abnormal state, the preset wearable device does not send a connection response to the terminal, that is, the preset wearable device fails to establish connection with the terminal, so that the terminal can determine that the current input environment is an abnormal environment.

And if the terminal sends a connection request to the preset wearable device through the WI-FI, the terminal and the preset wearable device both need to be connected with the same WI-FI. After the terminal sends a connection request to the preset wearable device through the WI-FI, if the preset wearable device and the terminal are connected with the same WI-FI, the preset wearable device receives the connection request and sends a connection response to the terminal, so that the terminal can determine that the current input environment is a normal environment; if at least one of the preset wearable device or the terminal is not connected with the same WI-FI, the preset wearable device does not receive the connection request sent by the terminal and does not send a connection response to the terminal, so that the terminal can determine that the current input environment is an abnormal environment.

The terminal determines current geographical position information, and if the current geographical position information is displayed as a private position, the current input environment is determined to be a normal environment; and if the current geographical position information is displayed as a public position, determining that the current input environment is an abnormal environment.

In the embodiment of the present disclosure, the terminal may determine the current geographic location information based on a GPS (Global Positioning System), WI-FI, or the like. For the method of determining the current geographical location information based on the GPS, the terminal provides a location setting page for the user, on which the user can use the geographical location information such as a home, a company, etc. as a private location, use other locations except the private location as public locations, and store the private location set by the user by the terminal. When an input method in a system carried by the terminal is called, the terminal can carry out positioning through a GPS (global positioning system), acquire current geographical position information, simultaneously acquire a stored private position set by a user, and compare the private position set by the user with the current geographical position information; if the private position set by the user is consistent with the current geographical position information, determining the current input environment as a normal environment; and if the private position set by the user is inconsistent with the current geographical position information, determining that the current input environment is an abnormal environment.

For the mode of determining the current geographic position information based on the WI-FI, the terminal provides a WI-FI setting page for the user, the user can add the WI-FI identification of the WI-FI provided by a family, a company and the like to a private position on the WI-FI setting page, namely, the family, the company and the like are taken as the private position, and the terminal stores the WI-FI identification set by the user. When an input method in a system carried by the terminal is called, the terminal searches for the WI-FI identification of at least one WI-FI at the current position, acquires the stored WI-FI identification set by a user, and compares the WI-FI identification of at least one WI-FI with the WI-FI identification set by the user; if the WI-FI identification set by the user is consistent with one WI-FI identification in the at least one WI-FI identification, determining that the current input environment is a normal environment; and if the WI-FI identification set by the user is inconsistent with all WI-FI identifications in the at least one WI-FI identification, determining that the current input environment is an abnormal environment.

When the terminal detects the current input environment, the terminal only needs to detect the current input environment according to a detection method preset by the user. If the detection method preset by the user is a plurality of methods in the three methods, the plurality of methods do not have execution sequence.

In step 203, the terminal hides the target candidate word in the at least one second candidate word, displays the at least one first candidate word, and ends.

In an embodiment of the present disclosure, the target candidate word is a partial candidate word or a full candidate word in the at least one second candidate word.

And if the target candidate word is all the candidate words in the at least one second candidate word, the terminal directly hides all the candidate words in the second candidate word. Since directly hiding all the candidate words in the second candidate words may not be convenient enough for the user to input words in the input box and display of the candidate words is not intelligent enough, the disclosure may also hide part of the candidate words in the at least one second candidate word, that is, the target candidate word is part of the candidate words in the at least one second candidate word, thereby providing convenience for the user and avoiding disclosure of privacy of the user. If the target candidate word is a partial candidate word in the at least one second candidate word, the terminal needs to set an input box level for the input box first, and determine the target candidate word in the at least one second candidate word according to the input box level of the current input box, which includes the following specific steps:

step one, the terminal determines the input box grade of the input box based on the input box identification of the input box.

When the user performs an input, in order to store a word or the like input by the user in association with an input box rank, the input box rank of the input box may be determined based on the input box identification of the input box. In the embodiment of the disclosure, each input box corresponds to one input box identifier, so that when the terminal acquires the input box identifier of an input box, the terminal may acquire the input box identifier of the input box by calling an interface of an operating system carried by the terminal, and determine the input box level of the input box from a preset corresponding relationship between the input box identifier and the input box level based on the input box identifier. The input box levels may include a dangerous secret level, a serious secret level, a general secret level and a normal level.

The preset corresponding relation between the input box identifier and the input box grade can be obtained by the terminal from the server after the server is set, and can also be set by the user on the terminal.

In one possible implementation, the server may set the following according to a default input box level of user privacy settings to which the input box may relate:

for input boxes related to user privacy such as user identification numbers, account passwords and the like, the server can default the input box level to a danger-related level;

for input boxes related to user privacy such as user name, mobile phone number, etc., the server may default its input box level to a severe privacy level;

for input boxes that involve user privacy, such as a user's login account in an application, the server may default its input box level to a general privacy level;

for input boxes that do not involve user privacy, the server may default its input box level to a normal level.

In another possible implementation manner, if the input box level of the input box is the input box level set by the user for the input box through the terminal, the terminal may provide the user with an input box level setting entry. When a user clicks the input box grade setting entry, the terminal provides an input box grade setting page for the user, a pull-down menu comprising a dangerous secret-related grade, a serious secret-related grade, a general secret-related grade and a normal grade is provided for each input box in the terminal, the user sets the input box grade of the input box in the pull-down menu corresponding to the input box, and the input box identification of the input box set by the user is correspondingly stored with the input box grade by the terminal.

Wherein the terminal may maintain in a local storage a list of input box levels, such as table 1, for storing correspondences between input box identifications and input box levels.

TABLE 1

And secondly, recording words input by the user in the input box by the terminal, taking the words as second candidate words, and correspondingly storing the second candidate words and the preset input box into a grade list.

In the embodiment of the disclosure, when the terminal detects that the user inputs a word in the input box, the terminal records the word input by the user in the input box, uses the word as a second candidate word, acquires an input box identifier of the input box, and stores the input box identifier and the second candidate word in the rank list in a corresponding manner.

And the second candidate word is a word recorded by the terminal and input by the user in the history input process. For example, if the user inputs the complete identification number "5201401987 xxxxxxxx" in the input box, the terminal records the identification number "5201401987 xxxxxxxx", and uses the identification number as the second candidate.

And after the terminal takes the words recorded in the input box as a second candidate word, storing the second candidate word in a second word bank, determining the input box grade of the input box in the mentioned input box grade list based on the input box identification of the input box, and storing the second candidate word and the input box into the grade list in a corresponding grade mode.

For example, if the user inputs the complete identification number "5201401987 xxxxxxxx" in the input box with the input box identification "ID Card No", the terminal stores "5201401987 xxxxxxxx" as the second candidate word in the second thesaurus, and determines that the input box rank of the input box is "dangerous classified rank" in the aforementioned input box rank list based on the input box identification "ID Card No", the terminal stores the "dangerous classified rank" and "5201401987 xxxxxxxx" in the rank list in association with each other.

The terminal may maintain a rank list as shown in table 2, and store the input box rank of the input box and the second candidate word in the rank list.

TABLE 2

After the input box grade of the input box is determined, the terminal can provide a candidate word display mode setting entrance for the user. When the user clicks the candidate word display mode setting entry, the terminal provides a candidate word display mode setting page for the user, and provides a pull-down menu for setting the candidate word display mode when the input environment is abnormal. Wherein, the pull-down menu can comprise a whole display and a part of display. The user can set the display mode of the candidate words by selecting the whole display or partial display, and the terminal stores the setting of the user.

After the first step and the second step are executed, when the terminal calls an input box in the operating system according to the requirements of the user, the target candidate word can be determined in at least one second candidate word by executing the following third step and fourth step.

And step three, the terminal determines the input box grade corresponding to the input box identification based on the input box identification of the input box.

In the embodiment of the present disclosure, the specific process of step three is the same as that of step one, and details are not repeated here.

And fourthly, the terminal acquires at least one input box grade higher than the input box grade from the grade list based on the input box grade, and takes a second candidate word corresponding to the at least one input box grade as a target candidate word.

In the embodiment of the disclosure, the terminal compares the input frame level of the input frame with other input frame levels in the level list, obtains at least one input frame level higher than the input frame level, obtains the level list, obtains second candidate words corresponding to the at least one input frame level in the level list based on the at least one input frame level, and takes the second candidate words as target candidate words.

For example, if the input box level is "general classified level", see table 1, the input box levels higher than the "general classified level" are "dangerous classified level" and "serious classified level", respectively; then, the terminal acquires a rank list, referring to table 2, acquires "5201401987 xxxxxxxxxx", "5201431993 xxxxxxxx", "zhang" and "1884267 xxxx" corresponding to the "dangerous classified rank" and the "serious classified rank" in the rank list, and takes the candidate words as target candidate words.

And after the target candidate word is determined, the terminal displays a second candidate word according to the display mode of the candidate word set by the user when the input environment is abnormal. If the display mode of the candidate words set by the user is partial display, the terminal displays the target candidate words determined in the second candidate words through the fourth step; and if the display modes of the candidate words set by the user are all displayed, the terminal displays all the second candidate words.

In step 204, if the current input environment is a normal environment, determining the application program type of the application program; if the application program type of the application program is a private application program, execute step 203; if the application type of the application is a normal application, the following step 205 is executed.

The inventor has realized that in case of a current input environment being a normal environment, the security and privacy requirements may be different for different applications, and the user may also wish to display different candidate words. For applications involving personal privacy of bank accounts, payment accounts, etc., the user may not need to display the second candidate word; for some applications that do not involve personal privacy, the user may need to display the second candidate word for convenience, so that in the case where the current input environment is a normal environment, the terminal may continue to determine the application type of the application, and thus how to display the candidate word.

In the embodiment of the present disclosure, if the terminal determines that the current input environment is a normal environment, the terminal may continue to determine the application type of the application, where the application type at least includes a common application and a private application.

When determining the application type of the application, the terminal can determine the application as a private application based on the function or name of the application, and for the application which may relate to a bank account, a payment account and the like, the terminal can determine the application as the private application; for applications that do not involve user privacy, such as forums, video applications, etc., the terminal may determine the application as a generic application.

If the application program type of the application program is the private application program, the terminal executes step 203 to hide the target candidate words and display at least one first candidate word.

Optionally, after determining that the current input environment is a normal environment, step 204 may be omitted, and step 205 described below may be directly performed, or after completing performing step 204, step 205 described below may be continuously performed, which is not specifically limited in this disclosure.

In step 205, if the application program type of the application program is a common application program, the terminal determines the input box type of the input box in the application program; if the input box type of the input box is the private input box, execute step 203; if the input box type of the input box is a normal input box, the following step 206 is performed.

The inventors have recognized that for some common applications, where multiple input boxes may be involved, and where the security and privacy requirements of each of the multiple input boxes may be different, the user may also wish to display different candidate words. For an input box requiring input of personal privacy such as a password, an identification number and the like, the user may not need to display a second candidate word; for some input boxes that do not require personal privacy to be entered, the user may need to display the second candidate word for convenience, so the terminal may determine how to display the candidate word by determining the input box type of the input box.

In the embodiment of the disclosure, after determining that the application program type of the application program is a common application program, the terminal acquires an input box type list, and determines an input box type corresponding to an input box identifier in the input box type list based on the input box identifier of the current input box. The input box type list is used for storing the corresponding relation between the input box identification and the input box type. The correspondence relationship may be manually set by the user or may be preset by an operating system installed in the terminal. In an implementation mode of manual setting by a user, the terminal can provide an input box type setting entry, when the terminal detects that the user clicks to enter the input box type setting entry, the terminal can obtain an input box identifier of the input box, and provide a pull-down menu comprising a private input box and a common input box for the user, and after the user completes setting of the input box type, the terminal can correspondingly store the input box identifier and the input box type set by the user into a local memory of the terminal. The terminal may maintain a list of input box types as shown in table 3, for storing the correspondence between the input box identifier and the input box type.

TABLE 3

Input box identification	Type of input box
		ID Card No	Private input box
Name	Private input box
		Account	Common input box
Search	Common input box
		…	…

If the input box type is the private input box, the terminal executes the step 203 to hide the target candidate words and display at least one first candidate word.

Optionally, after determining that the current input environment is a normal environment, the step 204 may be omitted, the step 205 may be directly executed, or the step 205 may be executed after the step 204 is executed, or the step 204 may not be executed again, and the candidate word is directly displayed according to the determined candidate word display manner, which is not specifically limited in this embodiment of the disclosure.

In step 206, the terminal displays at least one first candidate word and at least one second candidate word.

In the embodiment of the disclosure, if the terminal determines that the input box is a normal input box based on the input box identifier of the input box in the input box type list, the terminal displays all the first candidate words and all the second candidate words.

In another embodiment, the purpose of detecting the current input environment is achieved by determining the account type of the current login account in the application program, sending a connection request to the preset wearable device and determining the current geographic position information, so that the obtained detection result is more accurate when the current input environment is detected.

In another embodiment, in the case that the current input environment is the normal environment, by determining the program type and the input box type of the application program, it is determined whether to display some candidate words that are accumulated by the user in the history input process and may relate to the personal privacy of the user, so that in the case that the current input environment is the normal environment, the personal privacy of the user may be leaked, and the security of the terminal is improved.

In another embodiment, the result obtained by determining the input box type is more accurate by obtaining the list of input box types and determining the input box type of the input box based on the input box identification of the current input box.

In another embodiment, the purpose of storing at least one second candidate word and the input box corresponding to the input box in a corresponding manner is achieved by determining the input box grades of the input boxes, recording words and phrases input by the user in the input boxes with different grades, and taking the words and phrases as the second candidate word, so that the candidate words can be displayed according to the input box grades, convenience is provided for the user, and the privacy of the user is prevented from being revealed.

In another embodiment, based on the input box level of the input box in the application program, at least one input box level higher than the input box level of the input box is determined, the candidate word corresponding to the at least one input box level is used as the target candidate word, and the target candidate word is hidden, so that the purpose of displaying part of the candidate words in the second candidate word is achieved, and the mode of displaying the candidate words is more intelligent.
