Latest Patents

One of O'Keeffe's latest patents focuses on reducing false positives in digital streams examined by deterministic finite state machines. This innovation combines location-based pattern matching, such as on packet headers, with content-based pattern matching, like on payloads of packets. One of the schemes he developed allows for an automatic transition from a header match state into the initial state of a content matching machine. Another scheme utilizes a rules graph that defines strings of match states and examines a list of match states previously determined through header and content matching. This method is also capable of comparing offset and depth values associated with the match states against specific criteria.
