Title: Innovations of Xingxiang Jiang in Watermarking Technologies

Introduction

Xingxiang Jiang is a notable inventor based in Changsha, China. He has made significant contributions to the field of watermarking information security technologies. His innovative approach addresses critical challenges in the protection of Building Information Modeling (BIM) data.

Latest Patents

Xingxiang Jiang 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 that are vulnerable to primitive attacks. By utilizing the vertical stability of a model, Jiang 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.
