[0050] The electronic device according to the embodiment of the present invention is not limited to the aforementioned devices and may include new electronic devices according to technological advancements.
[0051] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.
[0052] FIG. 1 is a configuration diagram of an electronic device (1) according to an embodiment of the present invention.
[0053] As illustrated in FIG. 1, an electronic device (1) according to an embodiment of the present invention may include a display module (10), a fingerprint recognition module (20), a signal processing unit (100), a control unit (200), and a storage unit (300).
[0054] The display module (10) is a module for displaying execution information of an electronic device (1), and may include a cover window, a display panel, a touch panel, etc., which are not shown. The display panel may include, for example, an LCD (liquid crystal display), an LED (light emitting diode), an OLED (organic LED), a MEMS (micro electro mechanical system), electronic paper, etc., and may display a plurality of fingerprint information recognition areas for recognizing fingerprint information through the fingerprint information recognition module (20) described later. The touch panel may be included in the display module and may convert a user's touch input into an electrical signal using, for example, a capacitive method.
[0055] A fingerprint recognition module (20) is connected to a display module (10) and can recognize a user's fingerprint that comes into contact with the surface of the display module (10). This fingerprint recognition module (20) may include, for example, an ultrasonic fingerprint information recognition module. In this case, the fingerprint information recognition module (20) can generate and output ultrasonic waves directed toward the fingerprint information recognition area of the display module (10), and can determine the shape of the fingerprint by recognizing the ultrasonic waves reflected from the user's finger fingerprint. Although FIG. 1 illustrates the fingerprint recognition module (20) being positioned at the bottom of the display module (10), this is merely an example to aid in understanding the embodiment, and the fingerprint recognition module (20) may be included within the electronic device (1) in various forms, such as being integrally positioned in the display module (10) or positioned on the edge side of the electronic device (1).
[0056] The signal processing unit (100) can detect the user's touch or pattern drag from an electrical signal corresponding to the touch input or pattern drag input of the display module (10), and can read the user's fingerprint input by processing the value received from the fingerprint information recognition module (20). In addition, the signal processing unit (100) can generate a plurality of fingerprint recognition areas to detect the user's fingerprint input through the fingerprint recognition module (20).
[0057] FIG. 2 is a block diagram for specifically explaining the function of the signal processing unit (100) of FIG. 1.
[0058] As illustrated in FIG. 2, the signal processing unit (100) may include a touch detection unit (110) and a fingerprint detection unit (120).
[0059] The touch detection unit (110) can detect the user's touch operation from an electrical signal resulting from the user's touch input through the display module (10).
[0060] The fingerprint detection unit (120) is electrically connected to the fingerprint recognition module (20) and can detect the user's fingerprint input by processing the value received from the fingerprint recognition module (20).
[0061] Referring again to FIG. 1, the control unit (200) may include, for example, a microprocessor-based control processing unit, a graphics processing unit, etc., and can be implemented by an electronic device having at least one core. This control unit (200) can read and select data or commands stored in the storage unit (300) described later, and can record newly input data or commands in the storage unit (300). In addition, the control unit (200) can modify or delete data or commands that have already been recorded.
[0062] In particular, the control unit (200) determines the type of fingerprint input input to the electronic device (1) according to an embodiment of the present invention, and if the input fingerprint input is a rotating fingerprint, processes the input characteristics of the rotating fingerprint together with the input image of the rotating fingerprint into personalized information and stores it in the storage unit (300), loads the personalized information from the storage unit (300) when an authentication request for the rotating fingerprint is made, and outputs a fingerprint authentication result depending on whether the input image of the rotating fingerprint and the input characteristics match the personalized information due to the authentication request to the electronic device (1).
[0063] In addition, the control unit (200) can differentially manage personalized information based on the user's fingerprint input characteristics according to the recognition range of the fingerprint recognition area of the electronic device (1), and personalize fingerprint authentication based on this.
[0064] Here, the fingerprint recognition area may correspond to a plurality of location information on the display module (10), and the plurality of fingerprint recognition areas may be separated on at least a part of the display module (10) or formed over the entire area of the display module (10). The recognition range of such fingerprint recognition areas may be set differently depending on the fingerprint input method or hardware specifications of the electronic device (1).
[0065] The storage unit (300) stores at least one command or data executable by the control unit (200), and the stored command or data can be selected by the control unit (200). According to an embodiment of the present invention, the storage unit (300) may include a computer program including a command that stores an input image of a rotating fingerprint on a display module (10) representing a partial or full fingerprint recognition area, and processes and stores at least one of the input characteristics of the rotation direction, input time, angle, and input position of the input image as personalized information. Additionally, the storage unit (300) may store a computer program including a command that enables fingerprint authentication based on the previously stored rotating fingerprint image and personalized information according to the input characteristics when the input rotating fingerprint image and the input characteristics of the input rotating fingerprint image are input. The storage unit (300) may include a storage medium such as, for example, RAM (random access memory) or ROM (read only memory), and is not limited to a specific storage medium.
[0066] FIG. 3 is a block diagram for specifically explaining the function of the control unit (200) of FIG. 1.
[0067] As illustrated in FIG. 3, the control unit (200) may include a characteristic detection unit (210), an information management unit (220), and a fingerprint authentication unit (230).
[0068] The control unit (200) of FIG. 3 can differentially detect the input characteristics of a rotating fingerprint and manage them as personalized information depending on whether the fingerprint recognition area is formed in a part of the display module (10) or the fingerprint recognition area is formed in the entire area of the display module (10).
[0069] First, we will explain the case where a fingerprint recognition area is formed in a part of the display module (10).
[0070] When a fingerprint recognition area is formed in a part of the display module (10), the characteristic detection unit (210) detects the input start time of the part of the area, detects the rotation direction of the rotating fingerprint from the input start time, and when the detection of the rotation direction is completed, detects the input end time of the part of the area and can detect the input time of the rotating fingerprint based on the input start time and the input end time. At this time, the characteristic detection unit (210) can detect the rotation direction based on the central axis of the rotating fingerprint that is continuously captured in the part of the area.
[0071] The information management unit (220) can store the rotation direction and input time of the rotating fingerprint detected through the characteristic detection unit (210) in the storage unit (300) and manage them as personalized information. This personalized information can be loaded by the information management unit (220) during fingerprint authentication.
[0072] The fingerprint authentication unit (230) can authenticate the fingerprint of the authentication request based on whether the input image of the rotating fingerprint of the authentication request is matched with the input image processed with personalized information, and whether the input characteristics (rotation direction and input time) of the rotating fingerprint of the authentication request are matched with the input characteristics processed with personalized information.
[0073] Next, we will describe the case where the fingerprint recognition area is formed over the entire area of the display module (10).
[0074] When a fingerprint recognition area is formed over the entire area of a display module (10), the characteristic detection unit (210) detects the input start time of the entire area, detects the rotation direction of the rotating fingerprint from the input start time, and when the detection of the rotation direction is completed, detects the input end time of the entire area, detects the input time of the rotating fingerprint based on the input start time and the input end time, detects the angle of the rotating fingerprint based on the rotation direction and the input end time, and can detect the input position of the rotating fingerprint during the input time. At this time, the characteristic detection unit (210) can detect the rotation direction based on the center axis of the rotating fingerprint continuously captured over the entire area, detect the angle based on the center axis of the rotating fingerprint captured over the entire area during the input time, and detect the input position based on the X-axis and Y-axis coordinate values on the center axis of the rotating fingerprint over the entire area. Here, the angle can be detected based on the inclination of the rotating fingerprint on the X-axis and Y-axis of the entire area.
[0075] The information management unit (220) can manage the rotation direction, input time, angle, and input position of the rotational fingerprint detected through the characteristic detection unit (210) as personalized information by storing them in the storage unit (300). This personalized information can be loaded by the information management unit (220) during fingerprint authentication.
[0076] The fingerprint authentication unit (230) can authenticate the fingerprint of the authentication request based on whether the input image of the rotating fingerprint of the authentication request is matched with the input image processed into personalized information, and whether the input characteristics (rotation direction, input time, angle and input position) of the rotating fingerprint of the authentication request are matched with the input characteristics processed into personalized information.
[0077] Hereinafter, together with the configuration described above, a fingerprint registration method and a fingerprint authentication method of an electronic device (1) according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 9.
[0078] First, FIG. 4 is a flowchart illustrating an exemplary method for registering fingerprints of an electronic device (1) according to an embodiment of the present invention.
[0079] As illustrated in FIG. 4, during the fingerprint registration process, the control unit (200) of the electronic device (1) can detect a fingerprint input in a fingerprint recognition area formed on the display module (10) (S100), and if the detected fingerprint input is a rotated fingerprint input, it can determine the recognition range of the fingerprint recognition area (S102).
[0080] If the fingerprint recognition area of the current electronic device (1) is a recognition range for a part of the display module (10), the input characteristics of the rotated fingerprint, such as the rotation direction and input time of the rotated fingerprint, can be detected based on the input image of the input rotated fingerprint (S104).
[0081] When input characteristics regarding the rotation direction and input time of a rotating fingerprint are detected, the control unit (200) can store the input characteristics as personalized information in the storage unit (200) along with the input image (S106).
[0082] On the other hand, if the fingerprint recognition area of the current electronic device (1) is a recognition range for the entire area of the display module (10) (S108), the input characteristics of the rotated fingerprint, such as the rotation direction, input time, angle, and input position of the rotated fingerprint, can be detected based on the input image of the input rotated fingerprint (S110).
[0083] When input characteristics regarding the rotation direction, input time, angle, and input position of a rotating fingerprint are detected, the control unit (200) can store the input characteristics as personalized information in the storage unit (200) along with the input image (S112).
[0084] FIG. 5 is a detailed flowchart of the process (S104) for detecting the rotation direction and input time of the rotation fingerprint of FIG. 4.
[0085] As illustrated in FIG. 5, when a rotating fingerprint is input through the display module (10), the control unit (200) can detect the input start time of a part of the rotating fingerprint through the characteristic detection unit (210) (S200).
[0086] Afterward, the characteristic detection unit (210) can detect the rotation direction of the rotated fingerprint from the input start time (S202). Here, the rotation direction of the rotated fingerprint can be detected based on the central axis of the rotated fingerprint that is continuously captured in a part of the fingerprint recognition area.
[0087] When detection of the rotation direction of the rotation fingerprint is completed (S204), the control unit (200) can detect the input end time of some area (S206).
[0088] When such an input end time is detected, the control unit (200) can detect the input time of the rotating fingerprint based on the input start time and the input end time (S208). This input time may refer to the elapsed time during which the rotating fingerprint is input.
[0089] Figure 6 is a diagram illustrating an exemplary case of detecting the rotation direction and input time of the rotation fingerprint of Figure 5.
[0090] FIG. 6(a) illustrates a case where the rotation direction of a rotating fingerprint is input. As shown in FIG. 6(a), the rotation direction of the rotating fingerprint, which is input or has been input, can be determined based on the central axis of the rotating fingerprint that is continuously captured after the initial fingerprint input. FIG. 6(a) is a case where the rotating fingerprint rotates from left to right with respect to a part of the fingerprint recognition area of the display module (10), and the control unit (200) can detect the rotation direction of such a rotating fingerprint through the characteristic detection unit (210).
[0091] Figure 7 is a detailed flowchart of the fingerprint registration process for the entire area of Figure 4, that is, the process of detecting the rotation direction, input time, angle, and input position of the rotated fingerprint.
[0092] As illustrated in FIG. 7, when a rotating fingerprint is input through the display module (10), the control unit (200) can detect the input start time of the entire area of the rotating fingerprint through the characteristic detection unit (210) (S300).
[0093] Afterwards, the characteristic detection unit (210) can detect the rotation direction and angle of the rotation fingerprint from the input start time (S302).
[0094] When the detection of the rotation direction and angle of the rotating fingerprint is completed (S304), the control unit (200) can detect the input end time of the rotating fingerprint through the characteristic detection unit (210) (S306). Here, the rotation direction of the rotating fingerprint can be detected based on the central axis of the rotating fingerprint that is continuously captured in a part of the fingerprint recognition area.
[0095] When the input end time is detected, the control unit (200) can detect the input time of the rotating fingerprint based on the detected input start time and input end time (S308).
[0096] The sequence of detecting the input start time, detecting the rotation direction, detecting the angle, and detecting the input end time is an example to explain the embodiment of FIG. 7, and the order of the flowchart may be changed as needed. For example, the process may proceed in the order of detecting the input start time, detecting the rotation direction of the rotating fingerprint, detecting the input end time of the entire area once the detection of the rotation direction is completed, detecting the input time of the rotating fingerprint based on the input start time and input end time, and detecting the angle of the rotating fingerprint based on the rotation direction and input end time.
[0097] When an input time is detected, the control unit (200) can detect the input position of the rotating fingerprint during the detected input time (S310). This input time may refer to the elapsed time during which the rotating fingerprint is input.
[0098] FIG. 8 is a diagram illustrating an exemplary case of detecting the angle and input position of the rotating fingerprint of FIG. 7, and is a diagram illustrating an exemplary case of reflecting input characteristics in addition to the rotation direction and input time of the rotating fingerprint.
[0099] FIG. 8(a) illustrates a case where the angle of a rotating fingerprint is input. As shown in FIG. 8(a), the angle of the rotating fingerprint can be detected based on the central axis of the rotating fingerprint captured in the entire area during the input time after the initial fingerprint input. This angle of the rotating fingerprint can be obtained by determining the tilt of the input rotating fingerprint based on the X-axis and Y-axis of the two-dimensional area of the tilt sensor (not shown) included in the electronic device (1).
[0100] In addition, the input position of the rotating fingerprint can be detected based on the X-axis and Y-axis coordinate values on the center axis of the rotating fingerprint in the entire area of the fingerprint recognition area of the display module (10), as shown in FIG. 8 (b).
[0101] FIG. 9 is a flowchart illustrating an exemplary fingerprint authentication method of an electronic device (1) according to an embodiment of the present invention.
[0102] As illustrated in FIG. 9, during the fingerprint authentication process, the control unit (200) of the electronic device (1) can detect a fingerprint input in a fingerprint recognition area formed on the display module (10) (S400).
[0103] If the detected fingerprint input is a general fingerprint, the control unit (200) can perform a general fingerprint authentication process (S402). The general fingerprint authentication process may include processes for capturing a fingerprint image, determining whether the fingerprint image matches, and outputting a fingerprint authentication result according to the determination result. Since this general fingerprint authentication process is not an essential component of the embodiment of the present invention, a detailed description is omitted.
[0104] Meanwhile, if the detected fingerprint input is a rotating fingerprint input, the control unit (200) can capture the input rotating fingerprint image and determine whether the captured rotating fingerprint image matches a previously stored rotating fingerprint image (S406).
[0105] When the captured rotating fingerprint image matches the previously stored rotating fingerprint image, the control unit (200) can determine the recognition range of the fingerprint recognition area of the current electronic device (1) (S408).
[0106] If the fingerprint recognition area of the current electronic device (1) is a recognition range for a part of the display module (10), the control unit (200) can load personalized information previously stored in the storage unit (300) (S410). The previously stored personalized information is an input characteristic of a rotating fingerprint input to a part of the fingerprint recognition area, and such input characteristic may include, for example, the rotation direction and input time of the previously stored rotating fingerprint.

At this time, the previously stored personalized information is an input characteristic of a rotating fingerprint input to the entire fingerprint recognition area, and such input characteristic may include, for example, the rotation direction, input time, angle, and input position of the previously stored rotating fingerprint.
[0109] Subsequently, the control unit (200) determines whether the rotation direction, input time, angle, and input position of the loaded rotating fingerprint match the rotation direction, input time, angle, and input position of the input rotating fingerprint (S420), and if the rotation direction, input time, angle, and input position of the loaded rotating fingerprint match the rotation direction, input time, angle, and input position of the input rotating fingerprint, the control unit (200) can output a fingerprint authentication result (S414). The fingerprint authentication result may be, for example, the result of outputting a message indicating fingerprint authentication success to the display module (10), or the result of performing a subsequent process after fingerprint authentication.

In particular, by utilizing the rotation direction, input time, angle, and input position of the rotating fingerprint for fingerprint registration and recognition, it is expected that security and reliability can be further secured in platform environments such as electronic financial transaction systems and e-commerce systems.
