Disclosed herein is an object image capture apparatus. The object image capture apparatus includes a first camera unit, a second camera unit, and a control unit. The first camera unit obtains a wide-area view image by capturing a wide-area view region. The second camera unit obtains a close-up view image by capturing the close-up view region of the wide-area view region. The control unit controls the second camera unit by dividing the wide-area view image into a plurality of blocks, analyzing the resulting blocks, and defining a target block, in which a moving object is detected, as a close-up view region from among the plurality of blocks.

Object image capture apparatus and method

A fingerprint verification apparatus that adds chaff fingerprint information to real fingerprint information of a user and then, hides and stores the fingerprint information of the user with a polynomial generated by unique information of the individual, thereby safely protecting the important fingerprint information of the user stored in a storing unit from an external attacker and safely managing an private key using the fingerprint information when using the private key as the unique information for making the polynomial.

Fingerprint verification method and apparatus with high security

A user authentication method and apparatus using a face image are provided. The method includes transforming a face image in a normalized spatial domain into frequency-domain data, extracting valid transform coefficients from the frequency-domain data based on energy-concentrated region information, extracting a feature vector from the extracted valid transform coefficients, and performing user authentication by comparing the extracted feature vector with a previously registered feature vector. Accordingly, it is possible to perform user authentication using a face image while using a minimum data dimension, thereby improving the speed and precision thereof.
