Hiroshi Komazaki is an inventor associated with Kawasaki, Japan, and Fujitsu Corporation. His recorded patent concerns protecting moving images through electronic watermarking.
Latest Patents
Komazaki is credited with 1 patent: “Method, Apparatus and Computer Program for Inserting a Watermarking Program into an Image Processing Program.” The invention describes a tamper-resistant module that randomly selects a watermark-insertion module and places it in a randomly chosen non-operation area of an MPEG expansion module. The selected module can change between images in a moving-image sequence. By varying the watermarking algorithm, the method makes it especially difficult to remove the watermark completely from every image.
