Title: Tan Chen - Innovator in Watermarking Information Security Technologies

Introduction

Tan Chen is a prominent 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

Tan Chen 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, he constructs a mapping relationship between primitive clusters and watermarking bits. The method calculates norms of primitives within each cluster and employs the positivity and negativity of norm skewness measurements as eigenvalues to create a binary sequence. This sequence undergoes an XOR process with the original watermarking sequence to establish a robust zero-watermarking for BIM data. Experimental results demonstrate that this method possesses uniqueness, robustness, and security.
