Latest Patents

One of Cheung's latest patents focuses on document authentication. This invention describes a method, system, computer program, and web service for authenticating a document. The process involves receiving a request to verify the earliest date of a document, which includes the document itself. A signature of the received document is created by running it against a checksum algorithm. The system then searches a database for a matching signature and responds with a date associated with the matched signature. The checksum algorithm used is an MD5 algorithm, which produces a unique signature for each non-identical set of binary data. This ensures that no two sets of binary data will render an identical signature. Separate signatures are created for the content and formatting of the document.

Another significant patent by Cheung is an interactive speech recognition model. This invention provides a method and apparatus for updating a speech model on a multi-user speech recognition system with a personal speech model for a single user. For instance, in a car, a speech recognition system can include a generic speech model for comparison with user speech input. A personal speech model, connected via a mechanism such as a Bluetooth connection, allows for the updating of the generic speech model using received personal speech model components. This innovation enhances the accuracy of speech recognition by tailoring the system to individual user preferences.
