An authentication apparatus and method based on cognitive information. The authentication apparatus based on cognitive information includes an authentication request reception unit for receiving a request to authenticate an authentication target, a behavioral and contextual information collection unit for collecting behavioral and contextual information corresponding to the authentication target, a cognitive information extraction unit for extracting cognitive information corresponding to the request from previously stored big data, and an authentication processing unit for authenticating the authentication target in consideration of the behavioral and contextual information based on the extracted cognitive information.

Apparatus and method for authentication based on cognitive information

An apparatus includes a user input unit, a display unit, a control unit, and a buffer unit. The display unit includes a speed setting menu. The control unit selects a mode from the speed setting menu in response to the selection signal of the user, and controls a compression ratio of a voice codec and a transfer rate of a modem corresponding to a transmission-side radio, and a reception rate of a modem and a restoration rate of a voice codec corresponding to a reception-side radio, based on the selected mode. The buffer unit performs a storage function if there is a difference between the compression ratio of the voice codec and the transfer rate of the modem or if there is a difference between the reception rate of the modem and the restoration rate of the voice codec.

Apparatus and method for improving communication quality of radio

A data recording apparatus and method using three dimensional (3D) optical memory and an authentication apparatus and method using 3D optical memory are provided. The data recording apparatus includes a recording excitation light splitting unit, a condition storage unit, and a data recording unit. The recording excitation light splitting unit splits recording excitation light into first split light and second split light. The condition storage unit stores recording conditions including information about the waveforms, wavelengths and phases of the split light and information about an arrangement of reflection mirrors configured to reflect the split light. The data recording unit records storage data by making the split light incident on the 3D optical memory through the reflection mirrors under the recording conditions.
