Description

Electronic device and its biometric authentication UI operation method

Various embodiments relate to an electronic device and a method of operating a biometric authentication UI thereof.

As part of strengthening security, electronic devices provide a security release function using the user's biometric information. Biometric information may include the user's biometric characteristics, such as fingerprint, iris, voice, face, or blood vessels.

Recently, as electronic devices in the form of full front screens that use the entire front as a display have been released, biometric identification/authentication functions (e.g. FOD (fingerprint on display) or in-display fingerprint) through the display have been released. It's a trend.

UI (user interface) icons (e.g., fingerprint recognition icons, face recognition icons) that induce biometric authentication provided by electronic devices are provided as limited icons provided by vendors. For example, in the case of fingerprint authentication, fingerprint characteristic icons are uniformly used. Since these fingerprint characteristic icons only use fixed UI resources, the feedback effect on the authentication result also provides only an effect preloaded by the vendor and does not reflect the various characteristics of the authentication situation.

Accordingly, the fingerprint characteristic icon not only does not provide fun usability, but also does not support various feedback effects depending on the recognition situation, so real-time update may not be possible. Additionally, the fingerprint characteristic icon does not support the user's custom decoration function, and does not support separate optimization for each application.

In various embodiments, a method and device for customizing the biometric authentication UI of an electronic device for each user will be described.

In various embodiments, the user directly decorates and applies the biometric icon UI of the electronic device to improve usability and specialize UI functions by providing not only a new biometric icon UI according to various definitions, but also various effects based on the authentication result. I would like to explain the method and device that can do this.

In operation 845, if it is necessary to adjust the position and size of the custom biometric authentication UI object, the processor 220 may adjust the size of the UI object or correct the position of the UI object within the biometric measurement area of the biometric sensor.

For example, as shown in <901> of FIG. 9, the custom biometric authentication UI object 910 may be smaller than the size of the biometric measurement area 920 of the biometric sensor. When the electronic device displays the custom biometric authentication UI object 910 at the location of the biometric measurement area 920, the empty space around the border of the biometric measurement area 920 is corrected to display an animation or background effect to create a biometric measurement area ( The location of 920) can be recognized by the user.

For another example, as shown in <903> of FIG. 9, the location of the custom biometric authentication UI object 930 and the location of the biometric measurement area 920 may not match. The electronic device 101 checks the center point of the custom biometric authentication UI object 930 and the center point of the biometric measurement area 920, matches the center points, and corrects the position to display the custom biometric authentication UI object 930. can do.

In operation 855, the processor 220 may change the icon or background color (eg, screen background color) if the color of the custom biometric authentication UI object needs to be changed. For example, in a brightly lit environment (e.g., daytime), the processor 220 determines to change the custom biometric authentication UI object to a complementary color compared to the background of the biometric authentication screen, or in a darkly lit environment (e.g. : night), you can decide to change the custom biometric authentication UI object to a less saturated color.

According to some embodiments, operations 850 and 855 may be omitted.

In operation 860, the processor 220 may display a custom biometric authentication UI object.

Although not shown in the drawing, the processor 220 may record whether biometric authentication succeeds or fails after setting a custom biometric authentication UI object. For example, the processor 220 may collect biometric authentication UI information used when biometric authentication is successful and biometric authentication UI information used when biometric authentication fails, and obtain authentication success rate data.

For another example, when biometric authentication failures exceed a set number of times, the processor 220 may provide a guide recommending a custom UI object with a high recognition rate in addition to the currently applied custom UI object.
