Title: Luanyun Hu: Innovator in Watermarking Information Security Technologies
Introduction
Luanyun Hu is a prominent inventor based in Changsha, China. He has made significant contributions to the field of watermarking information security technologies, particularly in the context of Building Information Modeling (BIM) data. His innovative approach addresses critical challenges in the security of digital information.
Latest Patents
Luanyun Hu holds a patent for a "Zero-watermarking method and device for BIM data." This invention provides a solution to the limitations of existing zero-watermarking methods, which are vulnerable to primitive attacks. By utilizing the vertical stability of a model, Hu constructs a mapping relationship between primitive clusters and watermarking bits. He calculates norms of primitives within these clusters and employs the positivity and negativity of norm skewness measurements as eigenvalues to create a binary sequence. This sequence undergoes an XOR process with an original watermarking sequence to establish a robust zero-watermarking method for BIM data. Experimental results demonstrate that this method possesses uniqueness, robustness, and security.
