Abstract: An electronic device for iris recognition and an operating method thereof are provided. The electronic device includes a housing including a first surface, a display exposed through a first region of the first surface, a light emitting unit comprising light emitting circuitry disposed in a second region of the first surface, an image device comprising image acquiring circuitry disposed in a third region of the first surface, at least one processor disposed within the housing and electrically connected with the display, the light emitting unit and the image device, and a memory disposed within the housing and electrically connected with the at least one processor. The memory stores instructions that, when executed by the processor, cause the electronic device to store a reference template based on a first iris image which has been recognized using the light emitting unit and the image device, to authenticate a second iris image which has been recognized using the light emitting unit and the image device, using the stored reference template, and to store a template of the second iris image succeeded in authentication, as an additional template.

Abstract: An electronic device encrypting biometric information includes memory for storing instructions and a processor. The instructions may be configured to, when executed by the processor, cause the electronic device to obtain a transformation matrix that maps a first feature value related to first biometric information to a first codeword, generate a third feature value by applying the transformation matrix to a second feature value related to second biometric information, compare a cosine similarity between a second codeword most similar to the third feature value and the third feature value with a threshold, map the second feature value to the second codeword based on the cosine similarity being greater than the threshold, and generate a hashed second codeword based on the second codeword, and transmit or store the hashed second codeword.

Abstract: The electronic device according to an embodiment may include a display module, a UDC module, and a processor. The processor may operate to identify an operation mode of the UDC module. The processor may operate to change, when the operation mode is a first designated operation mode, transmittance of a UDC area in a display area of the display module, control the UDC module to configure a first path facing the sensor module, and obtain a first image based on light transferred to the sensor module. The processor may operate to change, when the operation mode is a second designated operation mode, the transmittance of the UDC area, control the UDC module to configure a second path facing the camera module, and obtain a second image based on light transferred to the camera module through the second path.

Abstract: Disclosed is an electronic apparatus including a first camera, a second camera, and a processor. The first camera includes a first FOV. The second camera includes a second FOV corresponding to part of the first FOV. The processor is configured to obtain a request associated with biometric authentication. The processor is configured obtain at least one first image using the first camera and at least one second image using the second camera. The processor is configured to identify a first external object that is included in the at least first image while obtaining the first image. While obtaining the at least one second image, the processor is configured to provide notification information for obtaining at least one image including the second external object when the second external object that is at least part of the first external object, is not included in the at least second image.

Abstract: Provided is a liveness verification method and device. A liveness verification device acquires a first image and a second image, and select one or more liveness models based on respective analyses of the first image and the second image, including analyses based on an object part being detected in the first image and/or the second image, and to verify, using the selected one or more liveness models, a liveness of the object based on the first image and/or the second image. The first image may be a color image and the second image may be an Infrared image.
