概要
- 論文の詳細を見る
This letter presents a novel quandtree-based image authentication technique especially suitable for the content authentication of high quality required digital images. The host image and the hiding marks generate quadtrees which record the information of host images. Any malicious tamper to the image is reflected from the recovered marks. Compared to other authentication schemes based on the fragile watermarking technique, the host image is not at all modified and the detection to malicious tamper is sensitive.
