Background

The password input is a simple and effective identity authentication and information security protection means, and the password input operation at the terminal equipment side is quite common, for example, the password of withdrawing money is input at a bank counter, or the password of opening the door is input at a door lock. The user inevitably needs to input some passwords to achieve the purpose of unlocking or logging in.

When a user inputs a password in different occasions, the user is easy to peep by surrounding personnel, and the problem of password leakage can be caused. In order to improve the security of password input, most software currently adopts a form invisible to a user for the password input by the user, for example, a space or an asterisk or other symbol is used to replace the character input by the user.

However, the space or star symbol is used to replace the input character, so that a certain protection effect is achieved, but other people can still guess the pressed key from the point pressing gesture and the position of the password inputter and deduce the password input by the user, so that the password input security is low.

Detailed Description

The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. Furthermore, the terms "comprises," "comprising," and "includes" and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.

The password input is a simple and effective identity authentication and information security protection means, the operation of inputting the password at the terminal equipment side is quite common, for example, the password of withdrawing money is input at a bank counter, the password of opening the door is input at a door lock, the password of starting up is input at a mobile phone, and the like. When a user inputs a password in a public place, the user is easy to peep by surrounding personnel, and the password can be leaked. Based on the information input method, the situation that a bystander sees the password input from the side face of the password input person can be avoided, and password content is difficult to infer according to the click gesture and the position of the password input person, so that the safety and the reliability of the password input process are improved.

In particular, for convenience of understanding, referring to fig. 1, fig. 1 is a schematic view of a scenario applied to a bank counter in an embodiment of the present application, where fig. 1 (a) illustrates a withdrawal password key interface seen by a user from a left side view, fig. 1 (B) illustrates a withdrawal password key interface seen by the user from a front view, and fig. 1 (C) illustrates a withdrawal password key interface seen by the user from a right side view. Although the drawing (a), the drawing (B) and the drawing (C) in fig. 1 are all drawing password key interfaces on the same bank counter, drawing password key interfaces seen from different angles have different display contents. That is, based on the (a) diagram in fig. 1, the key sequence from left to right, from top to bottom, is "4", "7", "6", "3", "2", "8", "5", "1", "0", and "9". Based on the (B) diagram in fig. 1, the key sequence from top to bottom is "6", "0", "7", "8", "2", "9", "5", "3", "4", and "1" in this order from left to right. Based on the (C) diagram in fig. 1, the keys from left to right, from top to bottom, are "0", "8", "3", "6", "9", "2", "4", "7", "1", and "5" in this order. Therefore, the information displayed by the same key position is different on the withdrawal password key interface seen from different angles. For example, when the withdrawal password is "1024" input by the user at the front view, the input password seen by the user at the left view is "9720", and the input password seen by the user at the right view is "5871", so that the withdrawal password content cannot be inferred by the user at the left view and the right view according to the point pressing gesture and position of the user at the front view, thereby improving the safety and reliability of the withdrawal password input process.

For the sake of understanding, please refer to fig. 2, fig. 2 is a schematic diagram of a scenario applied to the intelligent door lock in the embodiment of the present application, as shown in fig. 2 (a) illustrates a door lock password key interface seen by a user from a left side view, fig. 2 (B) illustrates a door lock password key interface seen by the user from a front view, and fig. 2 (C) illustrates a door lock password key interface seen by the user from a right side view. Similar to what is described in fig. 1, the same key positions exhibit different information in the door lock code key interface as seen from different angles. The user at the left view angle and the user at the right view angle cannot infer the password content of the door lock according to the click gesture and the position of the user at the front view angle, so that the safety and the reliability of the password input process of the door lock are improved.

For the sake of understanding, please refer to fig. 3, which is a schematic diagram of a scenario applied to a user terminal in the embodiment of the present application, as shown in fig. 3 (a) illustrates a mobile phone password input interface seen by a user from a left side view, fig. 3 (B) illustrates a mobile phone password input interface seen by the user from a front view, and fig. 3 (C) illustrates a mobile phone password input interface seen by the user from a right side view. A user may attach a lenticular film to the display screen to impart the functionality of a light field display to the display screen. The lenticular lens film is realized based on lenticular lens technology, and the principle of the lenticular lens technology is that a layer of lenticular lens is added in front of a liquid crystal display screen, and the image plane of the liquid crystal display screen is positioned on the focal plane of the lens, so that each sub-pixel can be projected by the lenticular lens in different directions. Thus, both eyes view the display screen from different angles and see different sub-pixels. At present, the lenticular lens film can support two parallax images on the left and right sides of the transverse screen, and it can be understood that the lenticular lens film can also support a vertical screen and can display more than two password input interfaces. Similar to what is described in fig. 1, in the mobile phone password input interface seen from different angles, the information displayed at the same key position is different, so that the safety and reliability of the mobile phone password input process are improved.

For ease of understanding, referring to fig. 4, fig. 4 is a schematic view of a scene applied to holographic projection in an embodiment of the present application, where fig. 4 (a) illustrates a holographic projection password input interface seen by a user from a left side view angle, fig. 4 (B) illustrates a holographic projection password input interface seen by the user from a front view angle, and fig. 4 (C) illustrates a holographic projection password input interface seen by the user from a right side view angle. The method and the device can utilize the negative refractive index plate to refract the stereoscopic content of the light field display to be displayed in the air, achieve the effect of holographic projection, and can display the holographic projection password input interface in the space without bearing entities (such as a display screen or a projection screen). Similar to what is described in fig. 1, the information presented by the same key position in the holographic projected password input interface seen from different angles is different.

For easy understanding, referring to fig. 5, fig. 5 is a schematic diagram of an architecture of an information input system in an embodiment of the present application, where the information input system includes a server and a terminal device, the terminal device sends a password input by a user to the server, the server verifies the password, and a verification result of the password is fed back to the terminal device. The server related to the application can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDNs), basic cloud computing services such as big data and artificial intelligence platforms. The terminal device may be, but is not limited to, a password input device, a holographic projection device, a smart phone, a tablet computer, a notebook computer, a palm computer, a personal computer, a smart television, etc. The terminal device and the server may be directly or indirectly connected through wired or wireless communication, which is not limited herein. The number of servers and terminal devices is not limited either.

Based on this, referring to fig. 6, fig. 6 is a schematic flow chart of generating a password key interface in the embodiment of the present application, and specifically, as shown in the drawings:

in step S1, the terminal device generates M preset key interface types, respectively labeled as P1. The preset key interface types are at least two, namely one preset key interface type is corresponding to a viewing angle range of 0-90 degrees from left to right, and the other preset key interface type is corresponding to a viewing angle range of 90-180 degrees from left to right.

In step S2, the terminal device sequentially renders 1 to N number of cipher key interfaces from left to right, the number of cipher key interfaces being N in total, the number of N being dependent on the hardware capabilities of the light field display. When the terminal equipment renders the x-th picture, the password key interface can adopt P (x/N x M) preset key interface types, so that the password key corresponding to the preset key interface types is rendered at the angle.

In step S3, the terminal device provides the rendered N password key interfaces.

With reference to the foregoing description, a method for inputting information in the present application will be described, referring to fig. 7, fig. 7 is a schematic diagram of one embodiment of a method for inputting information in an embodiment of the present application, where, as shown in the drawing, one embodiment of the method for inputting information in the embodiment of the present application includes:

101. The terminal equipment provides N password key interfaces, wherein the N password key interfaces correspond to M preset key interface types, each preset key interface type corresponds to a visual angle range, the password key interfaces corresponding to the same preset key interface type have the same key arrangement, the password key interfaces corresponding to different preset key interface types have different key arrangements, N is an integer greater than or equal to 2, M is an integer greater than or equal to 2 and less than or equal to N;

in this embodiment, the terminal device may provide N key interfaces for passwords using a light field display technology. The light field display technology can enable a user to see different pictures from different visual angles, and as two eyes of a person have a distance, parallax is caused by seeing the pictures from the two visual angles, so that a viewing effect of naked eye three-dimensional (3D) can be formed. The light field display that this application adopted can be lenticular lens display, adds one deck cylindrical lens grating on the liquid crystal display promptly, and cylindrical lens projects the different directions with the last different pixels of liquid crystal display.

In particular, the value of N depends on the light field display hardware capabilities. For example, a light field display may provide pictures at 45 different viewing angles, i.e., N equals 45.

And M is greater than or equal to 2, and if M is equal to 2, two preset key interface types are provided. For example, a viewing angle range of 0 ° (including 0 °) to 90 ° (including 90 °) from left to right corresponds to one preset key interface type, and a viewing angle range of 90 ° (excluding 90 °) to 180 ° (including 180 °) from left to right corresponds to another preset key interface type. Taking M equal to 3 as an example, the method includes a preset key interface type 1, a preset key interface type 2 and a preset key interface type 3. The view angle range corresponding to the preset key interface type 1 is 0-60 degrees (including 60 degrees), the view angle range corresponding to the preset key interface type 2 is 60-120 degrees (excluding 60 degrees) and 120-180 degrees (including 60 degrees), and the view angle range corresponding to the preset key interface type 3 is 120-120 degrees (excluding 120 degrees). It should be understood that, in practical applications, the viewing angle ranges corresponding to each preset key interface type need not be completely identical, for example, the viewing angle range corresponding to the preset key interface type 1 may also be 0 ° to 80 °, the viewing angle range corresponding to the preset key interface type 2 is 80 ° to 100 °, and the viewing angle range corresponding to the preset key interface type 3 is 100 ° to 180 °. It can be understood that the number of types of preset key interfaces is not too large, otherwise, the number of password key interfaces in each view angle range is reduced, and the user has a certain distance between eyes, so that the seen password key interfaces may be unclear due to parallax problem. The number of preset key interface types and the specific view angle range corresponding to each preset key interface type need to be flexibly determined according to actual conditions.

102. When the target object is in the first visual angle range, the terminal equipment displays a first password key interface, wherein the first password key interface corresponds to a first preset key interface type in M preset key interface types;

in this embodiment, if the target object is in the first view angle range, the target object sees a first password key interface corresponding to a first preset key interface type displayed on the terminal device. It will be appreciated that the target object may be a user, a user's eye position, or other device, etc., and is not limited herein.

For ease of understanding, referring to fig. 8, fig. 8 is a schematic diagram of an embodiment of the view angle range in the embodiment of the present application, as shown in the drawing, if the target object is directly in front of the password key interface, the view angle is 90 °, if the target object is at the leftmost side of the password key interface, the view angle is 0 °, and if the target object is at the rightmost side of the password key interface, the view angle is 180 °, moving from the leftmost side of the password key interface to the right front of the password key interface, i.e., the view angle moves from 0 ° to 90 °, and moving from the right front of the password key interface to the rightmost side of the password key interface, i.e., the view angle moves from 90 ° to 180 °.

Specifically, referring to fig. 9, fig. 9 is a schematic diagram of an embodiment of a preset key interface type according to the embodiment of the present application, where fig. 9 (a) is a password key interface corresponding to a preset key interface type 1, fig. 9 (B) is a password key interface corresponding to a preset key interface type 2, and fig. 9 (C) is a password key interface corresponding to a preset key interface type 3. If the first view angle range is 60-120 degrees and the target object is in the first view angle range, determining that the preset key interface type 2 is a first preset key interface type, and determining that the password key interface corresponding to the preset key interface type 2 is a first password key interface.

It should be understood that the foregoing examples are only for understanding the present solution, and the specific first view angle range and the first password key interface need to be flexibly determined according to practical situations.

103. And the terminal equipment acquires first input information based on K first keys displayed on the first password key interface when detecting the operation of at least one first key in the K first keys, wherein K is an integer greater than or equal to 2.

In this embodiment, since the first password key interface displays K first keys, the user operates at least one first key of the K first keys according to the set password, inputs the set password information, and the terminal device detects the operation to obtain the password information, where the password information is the first input information. Specifically, the operation in this embodiment may be a click operation or a press operation, and in practical application, the operation may also be a touch operation, a sliding operation, or a voice output operation, which is not limited herein. For ease of understanding, the present embodiment is described in terms of a purely numeric code key interface, assuming that K is equal to 10, and each first key corresponds to a number. It will be appreciated that the first code key interface may also include letters and special symbols.

Referring to fig. 10, fig. 10 is a schematic diagram illustrating an embodiment of obtaining first input information in the embodiment of the present application, as shown in the drawing, a user sequentially operates a first key "6", a first key "8", a first key "9" and a first key "7" in the first password key interface, where the terminal device may detect the operation, and obtain the first input information based on the operation, and the first input information is "6897".

Optionally, based on the embodiment corresponding to fig. 7, in an optional embodiment provided in the embodiment of the present application, the providing, by the terminal device, N number of password key interfaces may include:

the terminal equipment determines the total number of pictures of the renderable pictures according to the display capability of the light field display, wherein the total number of pictures of the renderable pictures is equal to N;

the terminal equipment renders N cipher key interfaces according to the total number of pictures of the renderable pictures and M preset key interface types, wherein at least one cipher key interface corresponding to each preset key interface type is rendered, and the sum of the cipher key interfaces corresponding to the M preset key interface types is equal to the total number of pictures of the renderable pictures.

In this embodiment, a method of rendering N number of key interfaces is described. The terminal device may determine the total number of pictures of the renderable pictures according to the display capability of the light field display, where the total number of pictures of the renderable pictures is N, and in this embodiment, the total number of pictures of the renderable pictures is 45 as an example. The terminal equipment obtains N cipher key interfaces through rendering according to the total number of the pictures of the renderable pictures and M preset key interface types, each preset key interface type corresponds to at least one cipher key interface, and the sum of the cipher key interfaces corresponding to the M preset key interface types is equal to the total number of the pictures of the renderable pictures.

The password key interfaces corresponding to each preset key interface type may be equally distributed or different, for example, the total number of the renderable pictures is 45, and three preset key interface types exist, so each preset key interface type may correspond to 15 password key interfaces respectively. Or, the preset key interface type 1 corresponds to 10 password key interfaces, the preset key interface type 2 corresponds to 15 password key interfaces, and the preset key interface type 3 corresponds to 20 password key interfaces. It should be understood that the number of password key interfaces corresponding to each preset key interface type is not limited herein, and the rendering manner is similar to that described in fig. 5, and will not be repeated here.

For convenience of understanding, please refer to fig. 11, fig. 11 is a schematic diagram of an embodiment of a plurality of key interfaces in the embodiment of the present application, and as shown in the figure, the preset key interface type 1 corresponds to 15 key interfaces, and the 15 key interfaces are the same. Similarly, the 15 cipher key interfaces corresponding to the preset key interface type 2 are the same, and the 15 cipher key interfaces corresponding to the preset key interface type 3 are the same.

Optionally, based on the embodiment corresponding to fig. 7, in an optional embodiment provided in the embodiment of the present application, after providing N number of password key interfaces, the method for inputting information may further include:

when the target object is in the second visual angle range, the terminal equipment displays a second password key interface, wherein the second password key interface corresponds to a second preset key interface type in the M preset key interface types, and the second preset key interface type and the first preset key interface type belong to different interface types;

and the terminal equipment acquires second input information based on K second keys displayed on the second password key interface when detecting the operation of at least one second key in the K second keys, wherein the key arrangement of the K second keys is inconsistent with the key arrangement of the K first keys.

In this embodiment, a method for displaying different password key interfaces in different viewing angle ranges is described. Because the light field display can display different interfaces at different angles, when the target object is in the second visual angle range, a second password key interface can be seen. The second password key interface belongs to a second preset key interface type, and the second preset key interface type and the first preset key interface type belong to different interface types, so that the difference between the first password key interface and the second password key interface can be determined.

After the terminal equipment displays the second password key interface, the second password key interface displays K second keys, the target object operates at least one second key in the K second keys according to the set password, the set password information is input, the terminal equipment detects the operation to obtain the password information, and the password information is the second input information.

For ease of understanding, three preset key interface types are taken as an example, and the first view angle range is 60 ° to 120 °, please refer to fig. 9 again, and as shown in the drawing, the first password key interface is shown in fig. 9 (B) assuming that the first view angle range is 60 ° to 120 ° corresponding to the preset key interface type 2. Assuming that the second view angle range is 0 ° to 60 °, and the target object is in the view angle range of 0 ° to 60 °, the preset key interface type 1 is a second preset key interface type, and the second password key interface is as shown in fig. 9 (a), it can be seen that 10 second keys in fig. 9 (a) and 10 first keys in fig. 9 (B) have different information at the same position.

Referring to fig. 12, fig. 12 is a schematic diagram illustrating an embodiment of obtaining second input information in the embodiment of the present application, as shown in the drawing, the target object operates a second key "4", a second key "3", a second key "8" and a second key "6" in the second password key interface, and at this time, the terminal device may detect the operation and obtain the second input information based on the operation, where the second input information is "4386".

In this embodiment of the present invention, a method for displaying different password key interfaces in different view angle ranges is provided, by which when a target object is in a second view angle range different from a first view angle range, a second password key interface different from a first password key interface is displayed, even if the target object performs password input on the same key position in the second password key interface, the obtained second input information is different from the first input information, so that password content cannot be inferred according to the key position of a password inputter, thereby improving security and reliability of a password input process.

Optionally, on the basis of the embodiment corresponding to fig. 7, an optional embodiment provided in the embodiment of the present application may further include:

if the first visual angle range is a preset visual angle range, the terminal equipment determines that K first keys displayed on the first password key interface and K preset keys have the same key arrangement, wherein the key arrangement corresponding to the K preset keys is real key arrangement;

if the first visual angle range is not the preset visual angle range, the terminal equipment determines that K first keys displayed on the first password key interface and K preset keys have different key arrangement.

In this embodiment, a method for displaying and displaying a real password key interface in a preset viewing angle is introduced. When the first visual angle range where the target object is located is a preset visual angle range, determining that K first keys displayed on the first password key interface and K preset keys have the same key arrangement, namely the real key arrangement at the moment. The first visual angle range is not a preset visual angle range, namely, when the visual angle range of the target object is not in the preset visual angle range, the terminal equipment determines that K first keys displayed on the first password key interface and K preset keys have different key arrangements, namely, the target object cannot see the real key arrangement. For the convenience of understanding, the front view angle range is taken as a preset view angle range, and in practical application, the preset view angle range and the real key arrangement can be flexibly set according to the particularities of the application scene, for example, the preset view angle range can also be a left view angle range or a right view angle range, and the application is not limited.

For ease of understanding, three types of preset key interfaces are taken as an example, and the preset viewing angle ranges from 60 ° to 120 °, please refer to fig. 9 again, where the key arrangement is shown in fig. 9 (a), fig. 9 (B), and fig. 9 (C). Since the preset viewing angle range is 60 ° to 120 °, the password key interface in the diagram (B) in fig. 9 belongs to the real key arrangement, and therefore, 10 preset keys (only digital keys) are displayed in the password key interface. If the first viewing angle range of the target object is 60 ° to 120 °, that is, the first viewing angle range is a preset viewing angle range. If the first viewing angle range of the target object is 0 ° to 60 °, or 120 ° to 180 °, i.e., the first viewing angle range is not a preset viewing angle range.

In the embodiment of the application, the method for displaying and displaying the real password key interface under the preset visual angle range is provided, and by the mode, because the key arrangement corresponding to the preset key is the real key arrangement, when the password inputter is in the preset visual angle range, the real key arrangement displayed by the terminal equipment can be seen, and when the password inputter is not in the preset visual angle range, the real key arrangement cannot be seen, so that the password content cannot be deduced by the non-password inputter according to the key position of the password inputter, and the safety and reliability of the password input process are further improved.

The terminal device determines a preset viewing angle range from the M viewing angle ranges based on the viewing angle range switching instruction. Based on the above, after the terminal device provides the N password key interfaces, the terminal device can display the real key arrangement when the target object is in the preset view angle range.
