Copyright Protection of Images Based on Large-Scale Image Recognition

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a method of copyright protection
for digital still images based on their recognition
with a large-scale image database.
For the purpose of copyright protection of images，
digital watermarking has been extensively studied for more than a decade.
However，it is still difficult to achieve enough robustness against
alternations such as StirMark attacks.
In order to solve this problem, we propose a method of copyright protection
based on new image recognition technologies that are tolerant to various
image distortions including geometric transformations.
The image recognition enables us to find a corresponding image
from at least tens of thousands of reference images to be protected
in response to a query image
that undergoes StirMark attacks and digital watermarking.
From experimental results using 10,000 images in the database，
we have confirmed that the method is capable of recognizing
99.5\% of query images
only within 216 ms / query (excluding feature extraction).
