Detailed Description

In order to make the objects, features and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Current electronic payments mainly include internet payments, mobile payments, and third party payments. In which there may be cross-business of electronic payments such as internet payments, mobile payments, and third party payments.

Fig. 1 and 2 are schematic diagrams illustrating a password input interface in the related art.

In the current electronic payment process, identity confirmation before payment is undoubtedly an important link for ensuring user information safety, although biometric authentication technologies such as face recognition or fingerprint recognition are applied with continuous development of scientific technology, the biometric authentication technology depends on biometric information, so that the uniqueness of the biometric information is the root of the biometric authentication technology, and once the biometric information is leaked, irreversible great loss is brought to a user. Therefore, whether from the wide range of applications or from the public acceptance, user identity confirmation by means of traditional password input is still the mainstream of the current society. Referring to fig. 1 and 2, password input interfaces for inputting a password by means of conventional password input on a mobile device and a cash dispenser, respectively, are shown.

It seems most convenient and secure to use traditional password entry as a means of pre-payment identity confirmation, but in practice there is still a risk of peeking. When the user is used as a payer and enters a payment password, the user may be peeped at the password by people behind or nearby, and unpredictable risks are generated once the user cannot timely perceive the password by himself. Particularly, when a password is input through a computer, a user usually sets some special characters, and the special characters need to be input by one hand during inputting, and the other hand presses the Shift key or the Ctrl key, so that the user cannot shield the password by hand in the process of inputting the password, and cannot implement other shielding measures, thereby having higher risk. Such a problem may exist in password input in mobile payment or in cash dispensers, that is, as long as various electronic payment methods such as mobile payment or third party payment are performed in a shopping mall, an office or other scenes with many people, there is a risk that the password input period is peeped as long as the identity is confirmed by the password input method. Therefore, a way to avoid the security problem of the keypad number password input is urgently needed.

Fig. 3 is a schematic diagram illustrating a digital input interface in the related art. The digital input interface shown in fig. 3 is generally in a form of combining an icon with a key, and is widely applied to cash dispensers and various electronic transactions, and in order to complete password input through the digital input interface, a user must use a finger to engage with a large displacement of a hand, so that a traditional password input is to make key selection by using the displacement of a fingertip engaging with the hand, but the present disclosure defines a password determination manner based on the defects of the existing password determination manner, and changes the traditional key stroke manner.

Fig. 4 shows a flowchart of a password determination method according to an embodiment of the present disclosure.

Referring to fig. 4, a processing flow of a password determination method according to an embodiment of the present disclosure at least includes the following steps:

and step S101, acquiring a motion track of a tool for inputting a password by a user.

In some embodiments, at least one digital coding database corresponding to the user can be constructed, and the motion trail of each tool for inputting the password by the user is stored in the digital coding database.

In some embodiments, the tool for inputting the password by the user may be a finger or a stylus, and the tool for inputting the password by the user is not limited herein. Correspondingly, if the tool for inputting the password by the user is a finger, the motion trail can be the handwriting of inputting the password by the finger of the user; if the tool for inputting the password by the user is a stylus pen, the motion trajectory may be handwriting of the password input by the user through the stylus pen, wherein the handwriting of the password input by the user through the finger may be different from the handwriting of the password input by the user through the stylus pen.

In some embodiments, the password entered by the user may be a number or a letter.

In some embodiments, the specific implementation process of obtaining the motion trajectory of the tool for inputting the password by the user at least includes:

step a, constructing a coordinate system based on a motion track;

and b, determining at least one group of digital codes corresponding to the motion track in the coordinate system.

In some embodiments, for step a, the constructed coordinate system may be a cartesian coordinate system, and the orientation of the coordinate system may also be defined based on numbers, and the construction manner of the coordinate system is not limited herein.

As an example, a plane rectangular coordinate system is constructed, wherein the positive y-axis direction is defined as North, and the North direction is assigned with the number 1, i.e. North =1; similarly, the y-axis negative direction is defined as the azimuth South, and the number 2 is assigned to the azimuth South, namely South =2; the positive x-axis direction is defined as the azimuth East, and the number 3 is assigned to the azimuth East, namely East =3; the x-axis negative direction is defined as the West direction, the West direction is assigned with the number 4, namely West =4, and the plane rectangular coordinate system is defined based on the number on the basis of constructing the plane rectangular coordinate system.

In some embodiments, different users have different writing habits, and different numbers or letters have different writing modes, so that different users input different numbers or letters and the same numbers or letters can generate different movement tracks, and the movement tracks can be acquired by a sensor in the electronic equipment. Such as: the method comprises the steps that a user inputs a number 1 on a touch screen through a fingertip, in the input process of the user, the contact area between the fingertip of the user and the touch screen and the pressing force change, wherein the change of the contact area is mainly reflected in the change of the position and the size of the area, in the process of inputting the number 1 of the user, the contact area between the fingertip of the user and the touch screen is gradually increased, the change of the position of the area is reflected in the fact that the contact area is increased towards one direction, the pressing force can be changed from light to heavy or from heavy to light, the changes are different from people, a sensor can acquire the changes, and therefore the motion track generated in the password input process of the user is acquired.

Among them, a technology in which a user inputs numbers or letters through a touch screen is a man-machine interaction technology widely used. The basic elements of the touch screen are sensors, and the touch screen is roughly classified into an infrared type, a resistive type, a surface acoustic wave type, and a capacitive type, according to the type of the sensor. During the process of inputting numbers or letters by a user, the sensor can acquire the change of the contact area between the tool for inputting the password by the user and the touch screen and the pressure degree. The touch screen is composed of a touch point detection component and a touch screen controller. The touch point detection component is arranged in front of the touch screen and used for detecting the position of a user touching the screen, the user can touch the screen through a fingertip, a corresponding touch signal can be generated at the moment, and the touch point detection component can send the touch signal of the user to the touch screen controller after receiving the touch signal of the user; the touch screen controller is mainly used for receiving a touch signal from the touch point detection part, determining a touch point coordinate corresponding to the touch signal, sending the touch point coordinate to a Central Processing Unit (CPU) of the password input device, and receiving and executing a command sent by the CPU of the password input device.

Step S102, determining corresponding digital codes based on the motion tracks.

In some embodiments, the same number or letter may have different movement traces when being input, and different movement traces may generate different number codes. Therefore, the digital codes corresponding to the motion tracks determined in the coordinate system can have multiple groups.

As an example, taking the number 0 as an example, in a planar rectangular coordinate system based on digital definition, the motion trajectory of the number 0 may be from North =1, via West =4, i.e. the digital code 14 is obtained; on the basis that the motion trajectory of the number 0 passes West =4, continue to pass South =2, i.e., obtain the digital code 42; on the basis that the motion trajectory of the number 0 passes through South =2, continuing to pass through East =3, namely obtaining a digital code 23; on the basis that the motion trajectory of the number 0 passes East =3, ending with North =1, the digital code 31 is obtained. Finally, the digital code corresponding to the motion track of the number 0 is obtained, namely 14- >42- >23- >31, wherein- > represents the sequence of the motion track of the number 0. If the motion trajectory of the number 0 starts from North =1 and ends at North =1 via East =3, south =2 and West =4, the finally obtained digital code becomes 13- >32- >24- >41.

In the embodiment of the disclosure, the coordinate system is constructed to reflect the change of the area and the direction generated during the contact period between the tool for inputting the password by the user and the touch screen, so that the password input by the user is digitized according to the coordinates.

In some embodiments, there may be cases where the same numerical code is determined based on different motion trajectories, and thus further recognition of the motion trajectories is also needed.

As an example, the numeric code determined by the coordinate system for both the number 9 and the number 4 may be 42- >30- >02.

In some embodiments, determining the specific implementation process of the corresponding digital code based on the motion trajectory may include at least:

step c, determining the number of the end points in the motion track;

and d, determining the input times corresponding to the motion track based on the number of the end points.

In some embodiments, the end point of the motion trajectory and the corresponding input times of the motion trajectory may reflect an input break point in the input process.

As an example, three strokes of the letter a are input according to a common handwriting, three end points can be obtained, three times of input are required, that is, three input break points are obtained when the input of the letter a is completed, and an input break point can also be understood as the number of strokes involved in the input process, that is, a point where a user lightly presses a touch screen through a tool for inputting a password, and the tool for inputting the password by the user is not limited here, and may be a finger or other tools.

The input breakpoint reflects the change of the area size of the tool for inputting the password by the user during the contact with the touch screen, if the user inputs the password through the fingertip, the change of the area size of the tool for inputting the password by the user during the contact between the fingertip and the touch screen is different from person to person, and if the user inputs the password through the stylus, the change of the area size of the tool for inputting the password by the user during the contact between the stylus and the touch screen is different according to the difference of the stylus. The number of times of introducing the input breakpoints, namely the number of strokes, can more accurately identify the password input by the user.

In the embodiment of the present disclosure, by further identifying the motion trajectory, under the condition that the motion trajectories are different and the digital codes are the same, the content input by the user can be identified more accurately, such as: although the numbers of the

numbers

9 and 4 determined by the coordinate system can be 42- >30- >02, the number of the end points in the motion trail of the number 9 is 1, and the input times is also 1, that is, 1 input breakpoint is provided for completing the input of the number 9; and the number of the end points in the motion track of the number 4 is 2, and the input frequency is also 2, namely 2 input break points exist when the input of the number 4 is completed, so that the number 4 and the number 9 can be accurately identified through comparison.

Step S103, determining the password based on the digital code.

In some embodiments, determining a specific implementation of a password based on a digital code may include:

matching the digital code with a digital code corresponding to a user in a digital code database to obtain a matching result;

and determining the matching result as the password.

As an example, if the number code obtained by the user 1 inputting the letter a is 42- >32- >30, the number code is matched with the number code corresponding to the user 1 in the number code database, and a matching result is obtained as the letter a, that is, the letter a is the password input by the user 1.

if the digital code is matched with the digital code corresponding to the user in the digital code database to obtain two or more matching results, determining the input times corresponding to the motion track;

a password is determined based on the number of inputs.

As an example, if the number code obtained by the user 1 inputting the number 9 is 42- >30- >02, the number code is matched with the number code corresponding to the user 1 in the number code database to obtain two matching results, which are the number 4 and the number 9 respectively, it is necessary to determine the input times corresponding to the motion trajectory to obtain that the input times corresponding to the actual motion trajectory generated by the user inputting the number 9 is 1.

In some embodiments, determining the specific implementation of the password based on the number of inputs may include:

and determining that the matching result which is consistent with the input times corresponding to the motion trail in the obtained matching result is a password.

As an example, although the number 4 and the number 9 are both the matching result, the number of inputs corresponding to the motion trajectory of the input number 4 is 2, and the number of inputs corresponding to the motion trajectory of the input number 9 is 1, which coincides with the number of inputs corresponding to the actual motion trajectory generated by the user inputting the number 9, that is, the number 9 is the password input by the user.

if the digital code is matched with the digital code corresponding to the user in the digital code database, and a matching result is not obtained, acquiring a password corresponding to the motion track;

and storing the digital codes to a digital code database corresponding to the user.

As an example, if the user 1 inputs the letter a to obtain a numeric code 42- >32- >32, matches the numeric code with the numeric code corresponding to the user 1 in the numeric code database, and if the numeric code is different from the numeric code 42- >32- >30 corresponding to the motion trajectory of the letter a stored in the numeric code database, and therefore a matching result is not obtained, the password corresponding to the motion trajectory generated by the user 1 in the input process is obtained as the letter a, and the numeric code 42- >32- >32 is stored in the numeric code database corresponding to the user 1.

The method for acquiring the letter a may be that after the user 1 inputs the password, the current interface prompts the user 1 in a dialog box manner that the password is not recognized, and guides the user 1 to complete confirmation of the letter a, and the method for acquiring the letter a is not limited here, and correspondingly, the method for acquiring the password corresponding to the motion trajectory is not limited here.

Fig. 5 is a schematic flow chart illustrating a password determination method according to an embodiment of the present disclosure.

Referring to fig. 5, another processing flow of a password determination method according to an embodiment of the present disclosure includes at least the following steps:

step S201, constructing a digital coding database corresponding to at least one user.

The motion track of the tool for inputting the password by the user is stored in the digital coding database, and it should be understood that the number of the users of the device may be 1, or may be other fixed numerical values. The digital coding database established for the user based on the motion track generated in the process of inputting the password by the user can also be understood as a customized coding database.

As an example, the number of users of the device M is 3, which are the device owner h and the parent of the device owner h, respectively, and the motion trajectories of the password input tools of the h and h parents are stored in the digital coding database. It should be understood that the user is not limited herein, and may be the device owner, or may be a family or friend of the device owner.

In some embodiments, the tool for inputting the password by the user may be a finger or a stylus, and the tool for inputting the password by the user is not limited herein. Correspondingly, if the tool for inputting the password by the user is a finger, the motion trail can be the handwriting of inputting the password by the finger of the user; if the tool for inputting the password by the user is a stylus, the motion trajectory may be handwriting of the password input by the user through the stylus, where the handwriting of the password input by the finger of the user and the handwriting of the password input by the user through the stylus may be different.

In some embodiments, the most common motion trajectory in the process of inputting numbers and letters can be investigated and collated to obtain a basic motion trajectory, and then a basic digital coding database is constructed based on the basic motion trajectory, which can be regarded as an existing coding database.

In some embodiments, the mobile device may maintain security of user information during the electronic transaction by installing an Application (APP), such as: in the electronic transaction process, the third-party payment system can call the installed APP through the interface to realize password input, so that the safety of the electronic transaction is improved.

As an example, a user may install a Finger pass APP on a mobile device, where the Finger pass APP can prompt and guide the user to input numbers and letters when the Finger pass APP is installed, obtain a motion track generated by the user inputting the numbers and letters, construct a digital coding database corresponding to the user based on the obtained motion track, that is, a customized coding database, and customize (customize) the digital coding database through a unique motion track generated by the user during inputting the numbers and letters, thereby increasing the recognition degree of a Password input by the user. When a user purchases goods in an online shopping mall, a Finger pass APP can be called through a third-party payment system on a payment interface, and Password input required in electronic transaction is completed by micro-actions of fingertips.

It should be understood that a password determination method of the present disclosure may be considered a specific input method, and the input interface may provide a plurality of input methods for the user to select. Such as: the input interface of the mobile device can provide a Sudoku input method, a full-spelling input method and a special input method for the user to select.

And step S202, constructing a coordinate system based on the motion trail.

In some embodiments, the constructed coordinate system may be a cartesian coordinate system, and the orientation of the coordinate system may also be defined based on numbers, and the manner of construction of the coordinate system is not limited herein.

As an example, a plane rectangular coordinate system is constructed, wherein the positive y-axis direction is defined as North, and the North direction is assigned with the number 1, i.e. North =1; similarly, the y-axis negative direction is defined as the azimuth South, and the number 2 is assigned to the azimuth South, namely South =2; the positive x-axis direction is defined as the azimuth East, and the number 3 is assigned to the azimuth East, namely East =3; the x-axis negative direction is defined as the azimuth West, and the number 4 is assigned to the azimuth West, namely West =4, so that the plane rectangular coordinate system is defined based on the number on the basis of constructing the plane rectangular coordinate system.

Step S203, at least one group of digital codes corresponding to the motion trail are determined in the coordinate system.

In some embodiments, the motion profile may be acquired by a sensor within the electronic device. Such as: a user inputs a number 1 on the touch screen through a fingertip, in the input process of the user, the contact area between the fingertip of the user and the touch screen changes, the change of the contact area is mainly reflected in the change of an area direction and an area size, and the sensor can sense and record the changes, so that a motion track generated in the process of inputting a password by the user is obtained.

In some embodiments, the same number or letter may have different movement tracks when being input, and different movement tracks may generate different number codes, so that the number codes corresponding to the movement tracks determined in the coordinate system may have multiple groups.

As an example, taking the number 0 as an example, in a planar rectangular coordinate system based on digital definition, the motion trajectory of the number 0 may be from North =1, via West =4, i.e. the digital code 14 is obtained; on the basis that the motion track of the number 0 passes West =4, continue to pass South =2, namely obtain the digital code 42; on the basis that the motion track of the number 0 passes through South =2, the rest =3 is continued, that is, the digital code 23 is obtained; on the basis that the motion trajectory of the number 0 passes East =3, ending with North =1, the digital code 31 is obtained. Finally, the digital code corresponding to the motion track of the number 0 is obtained, namely 14- >42- >23- >31, wherein- > represents the sequence of the motion track of the number 0. If the motion trajectory of the number 0 starts from North =1 and ends at North =1 via East =3, south =2 and West =4, the finally obtained digital code becomes 13- >32- >24- >41.

Step S204, determining the number of the end points in the motion trail.

In step S205, the number of inputs corresponding to the motion trajectory is determined based on the number of end points.

As an example, three strokes of the letter a are input according to a common handwriting, three end points can be obtained, three times of input are required, that is, three input break points are obtained when the input of the letter a is completed, and the input break points and the input break point times can also be understood as strokes and stroke numbers involved in the input process, that is, the input break points are points at which a user lightly presses a touch screen through a password input tool, and the password input tool of the user is not limited here, and can be a finger or other tools.

The input breakpoint reflects the change of the area size when a tool for inputting the password by the user is in contact with the touch screen, and the number of times of introducing the input breakpoint, namely the stroke number, can accurately identify the password input by the user.

In the embodiment of the present disclosure, by further identifying the motion trajectory, under the condition that the motion trajectories are different and the digital codes are the same, the content input by the user can be identified more accurately, such as: although the

numbers

9 and 4 can be 42- >30- >02 through the number codes determined by the coordinate system, the number of the end points in the motion track of the number 9 is 1, and the input times is also 1, namely 1 input breakpoint exists after the input of the number 9 is completed; and the number of the end points in the motion track of the number 4 is 2, and the input frequency is also 2, namely 2 input break points exist when the input of the number 4 is completed, so that the number 4 and the number 9 can be accurately identified through comparison.

In step S206, a password is determined based on the digital code.

and determining the matching result as a password.

As an example, if the number code obtained by inputting the letter A by the user 1 is 42- >32- >30, the number code is matched with the number code corresponding to the user 1 in the number code database, and a matching result is obtained as the letter A, that is, the letter A is the password input by the user 1.

a password is determined based on the number of inputs.

As an example, if the number code obtained by the user 1 inputting the number 9 is 42- >30- >02, the number code is matched with the number code corresponding to the user 1 in the number code database to obtain two matching results, which are the number 4 and the number 9 respectively, it is necessary to determine the input times corresponding to the motion trajectory, and the input times corresponding to the motion trajectory of the input number 9 is obtained as 1.

As an example, if the user 1 inputs the letter a to obtain the numeric code 42- >32- >32, matches the numeric code with the numeric code corresponding to the user 1 in the numeric code database, and is different from the numeric code 42- >32- >30 corresponding to the motion trajectory of the letter a stored in the numeric code database, and therefore a matching result is not obtained, the password corresponding to the motion trajectory generated by the user 1 in the input process is obtained as the letter a, and the numeric code 42- >32- >32 is stored in the numeric code database corresponding to the user 1.

That is, considering that there are differences in writing modes, a self-enhancement (self-enhancement) system is designed in addition to the basic digital code database, a self-enhancement mechanism is established through a program, when a password input by a user cannot be identified, the password input by the user is directly obtained and stored, and the storage mode is not limited here, and the digital code corresponding to the password input by the user can be stored in the digital code database, or the password itself can be stored in the word stock database.

The word stock library can be a large electronic resource library which is built by a computer technology and has a certain scale, and the large electronic resource library collects the actually appeared writing forms which can represent specific words or word variants in actual use.

Fig. 6 is a detailed optional flowchart of a password determination method according to an embodiment of the present disclosure.

Referring to fig. 6, taking an example that a user inputs a password A4P through a fingertip, a detailed optional process of the password determination method according to the embodiment of the present disclosure is described, which at least includes the following steps:

step S301, digital coding databases corresponding to two users are constructed.

Specifically, the first digital coding database is an existing coding database, wherein the most common motion trail in the input process of numbers and letters is investigated and sorted to obtain a basic motion trail, and the basic digital coding database is constructed based on the basic motion trail; the second digital coding database is a digital coding database established for the user based on the motion track generated in the process of inputting the password by the user, and can also be understood as a customized coding database.

Alternatively, the number of users of the device may be 1, or may be some other fixed number. Such as: the number of users of the device M is 3, which are the device owner h and the parent of the device owner h, respectively, and the motion trajectories of the password input tool by the h parent and the h parent are stored in the digital coding database. It should be understood that the user may be the device owner, or may be a family or friend of the device owner.

Optionally, the user may install a Finger Password APP on the mobile device, the Finger Password APP may prompt and guide the user to input numbers and letters when installed, obtain a motion trajectory generated by the user inputting the numbers and letters, construct a digital coding database corresponding to the user based on the obtained motion trajectory, that is, a customized coding database, and customize the digital coding database through a unique motion trajectory generated by the user during inputting the numbers and letters, thereby increasing the recognition degree of the Password input by the user.

Optionally, the Finger Password APP and the third party payment system may interact through an interface call, such as: when a user purchases goods in an online shopping mall, a Finger Password APP can be called through a third-party payment system on a payment interface, and therefore Password input required in electronic transaction is completed through micro-actions of fingertips.

Step S302, a plane rectangular coordinate system is constructed.

Specifically, as shown in fig. 7, the positive y-axis direction is defined as North azimuth, and the number 1 is assigned to North azimuth, that is, north =1; similarly, the y-axis negative direction is defined as the azimuth South, and the number 2 is assigned to the azimuth South, namely South =2; the positive x-axis direction is defined as the azimuth East, and the number 3 is assigned to the azimuth East, namely East =3; the x-axis negative direction is defined as the West bearing, and a number of 4 is assigned to the West bearing, i.e., west =4.

Step S303, at least one group of digital codes corresponding to the motion trail are determined in the plane rectangular coordinate system.

Specifically, the motion trajectory is a motion trajectory of the user inputting the password A4P through a fingertip, and may also be understood as handwriting related to the user inputting the password A4P through the fingertip.

Alternatively, the handwriting involved in inputting the letter A has three strokes, and the input sequence is as shown in FIG. 8.

Step 1:We go to direction 4for X and 2for Y as we draw line1；

Step 2:We go to direction 3for X and 2for Y as we draw line2；

Step 3:We go to direction 3for X and 0for Y as we draw line3。

Namely: when the first stroke of the letter A is input, the position of an X-axis direction defined as 4 is obtained, and the position of a Y-axis direction defined as 2 is obtained; when inputting the second stroke of the letter A, acquiring the position of which the X-axis direction is defined as 3 and the position of which the Y-axis direction is defined as 2; when the third stroke of the letter a is input, the orientation in which the X-axis direction is defined as 3 and the orientation in which the Y-axis direction is defined as 0 are acquired.

User input of the letter a results in a numeric code 42- >32- >30, and corresponds to the X-axis and the Y-axis.

Here, when the third stroke of the letter a is input, since the third stroke of the letter a is input horizontally, no change in the Y-axis is generated, and thus the Y-axis direction is defined as the orientation of 0. On the contrary, if the third stroke of the letter a is not horizontal, i.e. the Y-axis is changed, the orientation of the Y-axis defined as 0 is not obtained, and according to the angle of deviation of the third stroke of the letter a, the orientation of the Y-axis defined as 1 or the orientation of the Y-axis defined as 2 is obtained. The following combinations may therefore be produced:

42->32->30

42->32->31

42->32->32

by the method, the data code of the password A4P input by the fingertip of the user can be quickly established.

Step S304, determining the number of the end points in the motion trail.

In step S305, the input number corresponding to the motion trajectory is determined based on the number of end points.

Specifically, as shown in fig. 8, three strokes are input according to a common handwriting, three end points can be obtained, three times of input are required, that is, three input break points are obtained when the input of the letter a is completed, and the input break points can also be understood as the number of strokes involved in the input process, that is, the points at which the user's fingertip lightly presses the touch screen; similarly, two strokes are provided for inputting the number 4 according to the common handwriting, two end points can be obtained, two times of input are required, and two input breakpoints are provided for completing the input of the number 4.

Step S306, the digital code of the first password is matched with the digital code corresponding to the user in the digital code database to obtain a matching result, namely the letter A.

In step S307, the letter a is determined as the first password input by the user.

Step S308, the digital code of the second bit password is matched with the digital code corresponding to the user in the digital code database, and two matching results, i.e. the number 4 and the number 9, are obtained.

Specifically, if the digital code obtained by inputting the number 9 by the user is 42- >30- >02, the digital code is matched with the digital code corresponding to the user in the digital code database to obtain two matching results, namely, the number 4 and the number 9, the input frequency corresponding to the motion trajectory needs to be determined, and the input frequency corresponding to the motion trajectory of the input number 4 is obtained as 2.

In step S309, it is determined that the number 4 is the second password input by the user.

Specifically, since the input number of times corresponding to the movement trace of the input number 9 is 1, the number 4 of times corresponding to the movement trace of 2 in the matching result is the password input by the user.

Step S310, the digital code of the third-bit password is matched with the digital code corresponding to the user in the digital code database, if the matching result is not obtained, the password corresponding to the motion track is obtained, namely the third-bit password input by the user is the letter P.

Specifically, in consideration of differences in writing modes, a self-enhancement system is designed in addition to a basic digital coding database, a self-enhancement mechanism is established through a program, and when a password input by a user cannot be identified, the password input by the user can be directly obtained and stored.

Optionally, the manner of acquiring the letter P may be that after the user inputs the password, the current interface prompts the user in a dialog box that the password is not recognized, and guides the user to complete the confirmation of the letter P, where the confirmation manner may be that a selection is made among possible results, such as: the possible outcomes are the letters P and D, which are selected by the user.

And step S311, storing the letter P in a word stock corresponding to the user.

Optionally, when the user inputs a password through a fingertip, the touch screen identifies the fingerprint of the user, and compares the fingerprint with a fingerprint stored locally in the terminal device, so as to determine the identity of the user.

In the embodiment of the present disclosure, the input method can be understood as a special input method, and with reference to fig. 9, a user can complete password input only by performing a micro motion by a fingertip in a non-displacement state, so that not only can the password of the user not be peeped, but also the password input by the user can be effectively identified, and the security of user information is ensured.

Fig. 10 is a schematic diagram illustrating an actual scenario application of a password determination method according to an embodiment of the present disclosure.

Different from the traditional password input interface which needs a plurality of digital keys, the password determination mode defined by the disclosure only needs to set one key, referring to fig. 10, when a user types a password, the user only needs to place the fingertip of one finger on only one key, and the password of the user can be determined by performing a micro-motion on the key through the fingertip, and it should be understood that the micro-motion is performed in a state without any displacement. Because the fingertip input is a micro-action without any displacement, better safety can be provided through the mode, the safety risk brought by peeping is prevented, and the safety of user information is ensured.
