All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Apparatus embodiment
Referring to fig. 1, the structure of a contactless input device provided in an embodiment of the present application is schematically illustrated. As shown in fig. 1, the contactless input device includes:
a biometric module 100 and a contactless input module 200. Wherein, the biometric module 100 includes: a biological recognition layer 101. The contactless input module 200 includes: a character presentation layer 201 and a contactless character input layer 202. Only the module arrangement and the module-layer inclusion relationship in the contactless input device are shown in fig. 1. To facilitate an understanding of a specific implementation of the contactless input device, an example implementation of the contactless input device is described below in conjunction with fig. 2-8.
In this contactless input device, a biometric layer 101, a character display layer 201, and a contactless character input layer 202 are provided in a layered manner. The contactless character input layer 202 and the biometric layer 101 are located on the same side of the character presentation layer 201. Fig. 2 and 3 are side views of two implementations of a contactless input device, respectively. As shown in fig. 2, a contactless character input layer 202 may be located between the biometric layer 101 and the character presentation layer 201. In addition, the biometric layer 101 may also be located between the contactless character input layer 202 and the character presentation layer 201, as shown in fig. 3. Among the biometric layer 101, the character display layer 201, and the contactless character input layer 202, the character display layer 201 is farthest from the user.
A biometric layer 101 for capturing biometric features of a user using a contactless input device to identify the identity of the user. The biometric characteristic includes a physiological characteristic and/or a behavioral characteristic.
If the contactless character input layer 202 is located between the biometric layer 101 and the character presentation layer 201 as shown in fig. 2, the physiological characteristics collected by the biometric layer 101 may include at least one of the following, since it is located at the outermost layer:
fingerprint features, facial features, iris features, or finger vein features.
If the biometric layer 101 is located between the contactless character input layer 202 and the character presentation layer 201 as shown in fig. 3, there may be an inconvenient situation in recognizing facial features and iris features since the biometric layer 101 is not located at the outermost layer. Thus, in this arrangement, the physiological characteristics collected may include: fingerprint features and/or finger vein features.
In one possible implementation, the contactless character input layer 202, the biometric layer 101 and the character presentation layer 201 are parallel to each other, as shown in fig. 2 and 3. The non-contact character input layer 202 and the character display layer 201 are parallel to each other, so that the shielding position and the accurate recognition of the character can be realized. Furthermore, in order to facilitate the acquisition of physiological features, in another possible implementation (not shown in the figure), the biometric layer 101 may have a non-0 degree angle with respect to the character display layer 201, i.e. not parallel.
It should be noted that the above-described non-contact character input layer 202, biometric layer 101, and character display layer 201 may be flat surfaces or curved surfaces. And are not limited herein. Preferably, the contactless character input layer 202 and the character presentation layer 201 lie in two parallel planes.
In the embodiment of the present application, the biometric module 100 may include a biometric layer 101, and the biometric layer 101 collects various physiological characteristics of the user. Furthermore, the biometric module 100 may further include a plurality of biometric layers 101, and different biometric layers 101 are respectively used for acquiring different physiological characteristics of the user.
In the present embodiment, the biometric module 101 includes at least an acquisition function. In some possible implementations, the biometric module 101 may further include data processing functionality, such as recognizing the identity of the user based on the collected biometric features, and/or performing signal processing (e.g., filtering or amplification) on the collected biometric features, and so on. For the biometric module 101 with data processing function, it can obtain the user identification result by identifying the user's identity. For the biometric module 101 without data processing function, it can send the collected biometric features to the processing module inside or outside the contactless input device for processing, so as to realize the identification of the user identity.
The character display layer 201 is used for displaying a plurality of characters to be input. The characters to be input displayed by the character display layer are visible for users. Fig. 4 is a top view of a character display layer according to an embodiment of the present disclosure. As shown in fig. 4, the plurality of characters to be input may include numbers or symbols. Furthermore, the plurality of characters to be input may include letters. In the embodiment of the present application, the characters used for inputting in the contactless input device may be used to provide a password, a check code, or the like, or may also be an identification number, and the input purpose is not limited here. As a possible implementation, the characters presented are password characters.
In the embodiment of the application, the user realizes the non-contact input of the characters through the shielding operation. A contactless character input layer 202 for sensing light and obtaining shielded positioning information; the positioning information is used for determining the shielded characters in the characters to be input, and the shielded characters are used as the characters input by the user in a non-contact mode.
In this embodiment, the contactless character input layer 202 may be in a rectangular frame shape, and the shielded positioning information is determined by emitting light and sensing light through the peripheral sides, and the inside of the rectangular area surrounded by the sides may be penetrated and shielded by other articles that are convenient to insert, such as a user's finger, a sign pen, or a key. Fig. 5 is a top view of a contactless character input layer according to an embodiment of the present application. FIG. 6 is a schematic diagram of position detection by occlusion.
The following provides a specific implementation of the contactless character input layer 202. Referring to fig. 5, the contactless character input layer 202 is rectangular; the rectangle includes a first side 2021, a second side 2022, a third side 2023, and a fourth side 2024, wherein the first side 2021 is opposite the third side 2023, and the second side 2022 is opposite the fourth side 2024;
the first side 2021 is used for emitting light, and the opposite third side 2023 is used for sensing the light emitted from the first side 2021. The second side 2022 is for emitting light, and the opposite fourth side 2024 is for sensing the light emitted from the second side 2022. Referring to fig. 5 and 6, when an object passes through the character input layer 202 without contact, the third side 2023 and the fourth side 2024 respectively sense a light intensity change due to a shielding operation. Therefore, the non-contact character input layer 202 can position the shielding operation according to the light intensity changes sensed by the third side 2023 and the fourth side 2024, respectively, to obtain the positioning information.
With reference to fig. 4 and fig. 5, the positioning position of the blocking operation exactly corresponds to the character "2" displayed by the character exhibition layer 201, and therefore, the actually blocked character can be determined according to the positioning information and the corresponding relationship between the position on the character exhibition layer 201 and the character. The character "2" is the character that the user inputs in a non-contact manner.
In the contactless input device described in the above embodiment, the biometric recognition module 100 collects the biometric features of the user, so that the security of character input is enhanced, and the guarantee of the property security of the user is improved. In addition, the sanitary and maintainability of the device is further improved with the contactless input module 200. Compared with a contact type input device, the method can reduce the infection risk of diseases.
Fig. 7 is a top view of a biological recognition layer provided in an embodiment of the present application. As shown in fig. 7, the biometric layer 101 may include a plurality of biometric regions. Fig. 7 shows only one arrangement of the biometric regions, and the arrangement and number of the biometric regions in practical use are not limited to those shown in fig. 7. By way of example, the biometric identification layer 101 may be implemented by a technology of recognizing fingerprints through multi-angle high-definition camera shooting, and may also be implemented by a technology of recognizing finger veins through laser projection, and the specific implementation principle is not limited herein.
The character presentation layer 201 may be implemented by a display screen. In order to prompt the user that the input of the 1-bit character is completed, the character display layer 201 is further configured to change the current display state of the character display layer 201 to a preset display state, so as to prompt the user that the input of the current-bit character is completed. The current display state is a display state different from the preset display state. For example, the current display state is a screen being on, and the preset display state is a screen being off. The above-mentioned switching of the presentation state lasts only a short time, for example only 1 second off, and thereafter lights up as usual to present the characters to be entered, facilitating the user to continue to enter the next bit in a contactless manner. The preset display state can be any one of the following states: screen brightness reduction, screen flicker, screen display hue change, screen brightness improvement, and the like. Since the switching from the current display state to the preset display state is only to prompt the user that the input of the current character is completed, the preset display state is different from the current display state, and the implementation manner of the preset display state is not limited here.
After one character is input in a contactless manner, the character display layer 201 may continue to display a plurality of characters to be input, so that the user may continue to input the next character in a contactless manner. In practical applications, in order to enhance the security of character input, the position of the character may be changed. For example, the position of the character may be changed in a preset manner or may be changed in a random manner. By updating the positions of the displayed characters to be input, the safety of character input is improved, and the risk of stealing input contents is reduced.
Fig. 8 is a schematic structural diagram of another contactless input device provided in an embodiment of the present application. As shown in fig. 8, the contactless input device further includes: a processing module 300. The biometric module 100 and the contactless input module 200 are both connected to a processing module 300. The processing module 300 is configured to control the character display layer 201 to display a plurality of characters to be input, obtain a biological characteristic of the user acquired by the biological recognition layer 101, and obtain an identity recognition result for the user according to the biological characteristic; and obtaining the positioning information obtained by the non-contact character input layer 202, and determining the shielded characters according to the position information and the positioning information of a plurality of characters to be input.
The processing module 300 can obtain the corresponding relationship between the displayed character content and the character position, so that the shielded character can be accurately determined after the positioning information is obtained. In addition, for a scene in which the positions of a plurality of characters to be input are changed, the processing module 300 may also obtain the corresponding relationship between the updated and displayed character content and the character positions. I.e., a change in the position of the presented character does not affect the accuracy of the processing module 300 in determining the occluded character.
Based on the contactless input device provided by the foregoing embodiment, the present application also provides a method for determining a character input value. The method is specifically implemented by using any one of the contactless input devices. The following describes a specific implementation of the method with reference to the drawings and examples.
Method embodiment
Referring to fig. 9, the flowchart of a method for determining a character input value according to an embodiment of the present application is shown. As shown in fig. 9, the method of determining a character input value includes:
s901: and displaying a plurality of characters to be input by utilizing the character display layer.
The displayed characters to be input can be password characters, such as 0-9. Further, a character representing clearing or left-right shifting may be included such as c, ←, → or the like.
S902: and identifying whether the shielding operation is applied or not by utilizing the non-contact character input layer.
When the contactless character input layer recognizes the light intensity change, it can be confirmed that the shielding operation is applied. When the specific light intensity variation is not recognized, it indicates that the shielding operation is not applied.
S903: and after confirming that the non-contact character input layer is subjected to the shielding operation, acquiring the biological characteristics of the user using the non-contact input device by utilizing the biological recognition layer so as to recognize the identity of the user.
The contactless character input layer is applied with a blocking operation, indicating that there may be an effective contactless character input action, i.e. that the user has an intention to input characters through the contactless input device. At this time, in order to improve the property security of the user, the biological characteristics of the user can be collected through the biological identification layer so as to identify the identity of the user.
S904: and when the identity of the user passes the authentication, taking the shielded character corresponding to the positioning information obtained by the non-contact character input layer as the character input by the user in a non-contact manner to record.
When the user passes the authentication, the user is indicated to be authorized to input characters by using the contactless input device, for example, a withdrawal password of a certain bank card is input. At this time, the shielded character corresponding to the positioning information obtained by the non-contact character input layer may be recorded as the character input by the user in a non-contact manner.
It can be seen that the positioning information obtained by the contactless character input layer can be used to determine character input values, e.g., 0, 1, 2, 3, etc. Specifically, the input character can be determined according to the corresponding relationship between the character content and the character position on the character input layer and the positioning information actually detected by the non-contact character input layer.
In the method for determining the character input value provided by the embodiment, the biological characteristics of the user are collected through the biological recognition layer, the safety of character input is enhanced, and the guarantee of property safety of the user is improved. In addition, the sanitation and maintainability of the device are further improved by the non-contact character input layer. Compared with a method for determining a character input value under a contact type input device, the method can reduce the infection risk of diseases.
In order to prompt the user that the input of the current digit character is completed, and avoid the problems of repeated operation and low input efficiency, after the step S904 is executed, the method may further include:
and changing the current display state of the character display layer into a preset display state to prompt the user that the current character input is finished.
In order to prevent peeping and improve the security of input operation, after the recording of the character input value of the user determined by the contactless character input layer, the method may further include:
and updating the positions of the characters to be input displayed by the character display layer.
Fig. 10 is a flowchart of another method for determining a character input value according to an embodiment of the present application. As shown in fig. 10, after the character input value is recorded, it is possible to further determine whether the blocking is ended and determine whether the password is ended. If the password is finished (namely all the digits are input), entering subsequent transaction; if the password is not over, the position of the displayed character is updated.
The above description is only one specific embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered by the scope of the present application.
