Title: Yongwha Chung: Innovator in Fuzzy Vault Systems and Signature Verification
Introduction
Yongwha Chung is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the fields of fuzzy vault systems and online signature verification. With a total of 4 patents to his name, his work showcases innovative approaches to complex technological challenges.
Latest Patents
One of his latest patents is titled "Apparatus and method for polynomial reconstruction in fuzzy vault system." This invention provides a method for polynomial reconstruction that includes receiving a set of matching minutiae to select a minutiae combination for the reconstruction process. The method generates simultaneous equations using the selected minutiae combination and determines whether a root of these equations exists. If a root is found, the polynomial is reconstructed in real time, making it applicable to various fuzzy vault systems without requiring a separate user key.
Another notable patent is the "Apparatus for online signature verification using pattern transform technique and method therefor." This invention involves a signature data input unit that digitalizes a user's signature locus and reads it as a sequence of points. The system employs pattern transform units to perform speed equalization and velocity transformation on the signature sequence. It extracts three characteristic vectors to generate a difference vector, ultimately determining if the input signature matches a reference signature.
