A user authentication method for an electronic device is provided. The user authentication method includes detecting a content execution event, confirming an authentication level of content related to the detected content execution event, acquiring an appearance image through a camera unit, extracting valid regions related to an iris of a user from the acquired appearance image, and performing an authentication on the user by comparing iris authentication reference information related to a confirmed authentication level with the extracted valid regions.

User authentication method and electronic device supporting the same

A method for a device to acquire biometric information includes acquiring a plurality of images including an ocular region using an infrared ray (IR) image sensor, detecting a sclera region in each of the plurality of acquired images, sensing a change of the detected sclera region, and determining biometric information based on information on the sensed change of the sclera region.

Biometric information acquisition method and device for same

Disclosed is an optical gas sensor. The optical gas sensor includes: a light source which emits light; a gas collector which includes a cavity to be filled with gas to be sensed; an optical wave guider which guides light emitted from the light source to be output to the cavity, and guides the output light to be output again to the cavity after passing through the cavity of the gas collector; and an optical detector which detects light output from the optical wave guider. Thus, a path of light exposed to the gas to be sensed is increased within the cavity, thereby achieving miniaturization and sensing gas of low-concentration.

Apparatuses and methods which provide synchronized data using visible light communication are described. In one method, a first Light Emitting Diode (LED) lighting apparatus, which has a checked Identification (ID), receives a synchronization signal from a mobile communication network. This synchronization signal is analyzed in order to synchronize the first LED lighting apparatus with at least one second LED lighting apparatus adjacent to the first LED lighting apparatus. A synchronized time slot is prepared using the synchronization signal and a period of the time slot is determined, using the checked ID of the first LED apparatus, for transmitting data of the first LED lighting apparatus to a mobile terminal.
