Latest Patents

Sheng Chen holds a patent for a "Zero-watermarking method and device for BIM data." This invention provides a unique solution to the limitations of existing zero-watermarking methods, which are vulnerable to primitive attacks. The method constructs a mapping relationship between primitive clusters and watermarking bits, utilizing the vertical stability of a model. By calculating norms of primitives within each cluster, the method employs the positivity and negativity of norm skewness measurements as eigenvalues to create a binary sequence. An XOR process is then performed on this binary sequence and the original watermarking sequence to establish the zero-watermarking for BIM data. Experimental results demonstrate that this method possesses uniqueness, robustness, and security.
