Latest Patents

One of Yi-Chan Hung's latest patents is a semi-automatic rule generator. This invention involves a computer-implemented method for generating a first set of longest common sequences from a plurality of known malicious webpages. The first set of longest common sequences represents input data from which a human generates a set of regular expressions for detecting phishing webpages. The process includes obtaining HTML source strings from the known malicious webpages and transforming these strings to reduce the number of stop words and repeated tags. This transformation leads to a set of transformed source strings, which undergo string alignment to obtain a scoring matrix. The invention further includes obtaining a second set of longest common sequences and filtering it to derive the first set of longest common sequences.

Another significant patent by Yi-Chan Hung focuses on protecting computer users from online frauds, such as phishing and pharming. This invention describes a client computer that includes a page signature extractor and a policy enforcer. The page signature extractor encodes a web page to generate its signature, which is then compared with signatures of phishing pages on a remote server. The client and server communicate using the DNS protocol. The policy enforcer performs predetermined actions when a match is found, such as replacing the web page with a blocking page or displaying a warning message. This invention is crucial in determining if a web page is part of a phishing or pharming attack by comparing its URL to those of legitimate web pages.
