Abstract: A method and a device for recognizing an iris by using a CPA based on a cumulative sum are provided to authenticate a user by extracting iris feature from an iris image through the CPA based on the cumulative sum. A divider(310) converts the iris image into the images having a specific pixel size into polar coordinates and divides the polar coordinates into cells. A grouper(320) groups/outputs the first group comprising the fixed number of cells and the second group comprising the bigger number of cells than the first group. A feature vector generator(330) performs the cumulative sum-based CPA by using a feature value of each cell grouped in the first or second group as a representative value and generates a feature vector by assigning a different value to the cell corresponding to a change point and the remaining cells. An authenticator(340) performs authentication by comparing the generated feature vector with the registered feature vector.

Abstract: In an apparatus for authenticating a user by employing feature points of a fingerprint image of the user, a fingerprint image input circuit scans a fingerprint of a user to be registered to provide a first fingerprint image and a fingerprint of a user to be authenticated to provide a second fingerprint image. A host provides registered feature points data corresponding to the first fingerprint image and target feature points data corresponding to the second fingerprint image. A security token circuit estimates a position difference and a direction difference between pairs of a registered feature point and a target feature point and corrects the two feature points based on the position difference and the direction difference to provide authentication result data.
