Title: Jeng-Nan Tzeng: Innovator in Asymmetric Watermarking Technology
Introduction
Jeng-Nan Tzeng is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of watermarking technology, particularly through his innovative approach to asymmetric watermarking.
Latest Patents
Jeng-Nan Tzeng holds a patent for "Asymmetric Subspace Watermarking." This technology is designed to be particularly resistant to projection attacks. The process involves analyzing an original image to obtain its watermarking space, which is then divided into two orthogonal subspaces, g and h. An embedding key G, represented as a matrix, is selected, and a matrix H is calculated such that HG=0. The columns of matrix H form the bases of subspace h. A detecting key D is computed as the sum D= G, where B is a matrix. This results in a watermark w that is embedded into the original image, producing a watermarked image.
