Title:
APPARATUS AND METHOD FOR HIERARCHICALLY VERIFYING FINGERPRINTS USING SIMILARITY DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO/2012/138086
Kind Code:
A3
Abstract:
Provided are an apparatus and method for hierarchically verifying a fingerprint using similarity distribution. The fingerprint verifying apparatus comprises: a database unit for storing registered fingerprint images; a fingerprint image input unit for receiving a user's fingerprint image from a user; a distinct feature based fingerprint matching unit for extracting distinct features from the user's fingerprint image received through the fingerprint image input unit and the registered fingerprint images stored in the database unit, so as to match fingerprints based on the extracted distinct features; a similarity determination unit for determining whether the similarity between the user's fingerprint image and the registered fingerprint images is within a preset range; a binary image based fingerprint matching unit for matching fingerprints based on binary images; and a verification unit for verifying a fingerprint based on the binary images if the determined result by the similarity determination unit shows that the similarity is within the present range, and verifying a fingerprint based on the distinct features if the determined result by the similarity determination unit is that the similarity is not within the preset range.
