Latest Patents

Anthony Tung Shuen Ho holds a patent for "Methods for embedding image, audio and video watermarks in digital data." This invention presents a method for embedding an entire image, audio, or video watermark sequence within another data sequence while minimizing loss of quality. The method utilizes the de-correlation property of data coefficients in the orthogonal transform domain, similar to techniques used in data compression. The invention describes the use of a Discrete Cosine Transform as the embedding domain, although other orthogonal transforms can also be employed. A unique key derived from spatial locations is used to unlock or de-watermark the embedded sequences. Additionally, an exponential filter has been developed to manage watermark coefficients during the embedding and retrieval processes. This method is particularly useful in addressing multimedia copyright protection issues on the Internet and in the music industry.
