Latest Patents

Jong Jin Chae holds a patent for a "Method for embedding and extracting digital data in images and video." This method focuses on digital watermarking, allowing for the embedding of substantial amounts of data within images and videos. The technique utilizes a discrete wavelet transform to embed gray scale images, which can represent up to 25% of the host image data. A simple control parameter is adjustable for either hiding or watermarking purposes, ensuring robustness against operations like JPEG compression. The method incorporates noise-resilient channel codes based on multidimensional lattices, enabling the embedding of signature data such as gray-scale or color images. Additionally, it allows for the recovery of embedded image data without the original host image by inserting data into the host image in the DCT domain. This innovative approach also includes techniques for hiding speech within video frames.
