Latest Patents

Yuchen Hu's latest patents include a dual watermarking method for trajectory data and a generation method for zero watermarking. The dual watermarking method employs an encryption algorithm to create robust watermark information. It utilizes a farthest pair of feature points in a minimum convex hull as constant points. This method incorporates quantization index modulation technology to embed robust watermark information into angles formed by feature points and constant points. The resulting watermarks exhibit high robustness against various attacks, including translation, rotation, and scaling.

The second patent, concerning zero watermarking for trajectory data, outlines a generation and detection method that divides trajectory data into blocks based on a coordinate system. By using moment invariants of the trajectory in each block, a watermark sequence is constructed. This approach allows for copyright protection without altering the original trajectory data. The method demonstrates strong stability against common attacks, making it a valuable contribution to the field.
