Abstract
Studies of digital museum are making progress in various research institutes and universities. It is very important to leave great art works and cultural heritage for the future generation. These works are digitized, archived and stored in the digital museum. These digitized works can be shown without spatial restriction and the original works can be kept out of aged deterioration. However, the digital museum has a problem that no one can verify integrity of the digitized art works because of the nature of digital data. In this paper, a digital watermarking method for the digitized art works of 3D objects to detect error or tampering is proposed. We treat a 3D object as a group of still images. In our method, watermarking and adaptive coding are combined and the watermark is embedded in the images by using redundancy of choice of coding parameter. Signature of each image is embedded as a watermark in another image, so that the images are integrated each other. The special feature of our method is that the images never degrade by the embedding of the watermark.
