Abstract: An electronic device of determining proximity of a wireless external device is provided. The electronic device includes a transceiver, a sensor, and at least one processor, wherein the at least one processor is configured to transmit a first signal to the external device through the transceiver, acquire, when the first signal is transmitted, information about a user's gesture made in a vicinity of a sensor positioned within a certain distance from the transceiver through the sensor, wherein the first signal is distorted by the user's gesture and provided to the external device, receive, from the external device through the transceiver, a second signal generated as the external device copies the distorted first signal, and determine the proximity of the external device based on the second signal.

Abstract: The present disclosure relates to a method and device for determining, by an electronic device, proximity of an external electronic device. A method, performed by an electronic device, of determining proximity of an external electronic device includes: measuring a received signal strength indicator (RSSI) of a wireless communication signal received from the external electronic device when the electronic device is at a first position; measuring an RSSI of a wireless communication signal received from the external electronic device when the electronic device is at a second position different from the first position; and determining whether the external electronic device is proximate, based on a difference between the RSSI measured at the first position and the RSSI measured at the second position.

Abstract: A method of performing authentication by an electronic apparatus and an electronic apparatus for performing authentication are provided. The electronic apparatus receives an access request to an application executed on the electronic apparatus, obtain any one of public helper data and private helper data, which are used for user authentication, based on the access requested application, obtain an encryption key from user's biometric information received according to the access request, based on the public helper data or the private helper data by using a fuzzy extractor, and perform user authentication for accessing the application, based on the obtained encryption key.

Abstract: An electronic device is provided. The electronic device includes an input/output interface, and one or more processors configured to output a user authentication information restriction through the input/output interface, determine user input characteristics, based on user authentication information input based on the user authentication information restriction, and output, through the input/output interface, the user authentication information restriction updated based on the determined user input characteristics.
