Latest Patents

One of his latest patents is a "Watermarking system and methodology for digital multimedia content." This open digital watermark system features various functionalities that unify watermark production and processing across diverse multimedia terminals, such as set-top boxes, while ensuring compliance with OPIMA standards. The system employs intentional image warping to combat piracy, utilizes an analog video channel for downloading programming, and implements a packet signature for watermark insertion through pixel replacement. Additionally, it optimizes data processing and storage by leveraging the data stream.

Another significant patent is the "System and methodology for tracing to a source of unauthorized copying of prerecorded proprietary material, such as movies." This invention allows for tracing the source of unauthorized copies of information-bearing media, like video DVDs. It alters a compressed digital signal stream stored on the medium to include "running marks," which are pixel blocks that change position frame by frame and are encoded with information indicating where and when the copy was made. The playback of the medium under test is synchronized with a reference medium containing the locations of the running marks and original video. The source of the copying message is encrypted and scrambled to prevent detection or alteration by copyists, enhancing discrimination among multiple sources.
