Title: The Innovative Contributions of Han-Ul Jang in 3D Mesh Model Watermarking
Introduction: Han-Ul Jang is an accomplished inventor based in Daejeon, South Korea, known for his innovative work in the field of 3D model watermarking. With a total of three patents to his name, Jang has made significant strides in enhancing the security and integrity of three-dimensional models, especially in contexts like 3D printing.
Latest Patents: One of Jang's notable patents is titled "Three-dimensional mesh model watermarking method using segmentation and apparatus thereof." This invention reveals a method of inserting a watermark into a 3D mesh model via a divisional scheme. The process involves calculating geometric primitives of the mesh, dividing it into multiple segments, and embedding the watermark into these segments within a vertex distance-based coordinate system before restoring it to a Cartesian coordinate system. Jang’s second patent, "Watermark embedding apparatus and method, and watermark detecting apparatus and method for 3D printing environment," focuses on a method of embedding a watermark into a layered three-dimensional model. This technique aligns the model in the printing direction and embeds a watermark perpendicular to this direction, ensuring that the watermark's presence isn't linked to the printing process.
Career Highlights: Jang's professional journey has been tied to the Korea Advanced Institute of Science and Technology, where he has applied his expertise in 3D modeling and watermarking. His contributions to the institute not only highlight his skills as an inventor but also his commitment to advancing technology in the realm of 3D printing and digital security.
Collaborations: Throughout his career, Han-Ul Jang has worked alongside notable colleagues such as Heung-Kyu Lee and Jong-Uk Hou. Their collaborative efforts have likely helped foster innovative approaches to problem-solving in their shared field.
Conclusion: Han-Ul Jang's inventive spirit and dedication to improving 3D model security are evident through his patented technologies. His work at the Korea Advanced Institute of Science and Technology marks him as a key player in the evolution of 3D printing technology. As the landscape of digital modeling continues to grow, Jang’s innovations will undoubtedly contribute to its future advancements.
