Watermarking Algorithm for 1-bit Image Authentication using Block operation

블록별 연산을 이용한 1-bit 영상의 원본 증명용 워터마킹 알고리즘

In this Paper, we propose a new watermarking algorithm for 1-bit image authentication using block operation. Observing 3${\times}$3 block patterns, we find the regions to watermark, We describe a specific scheme how to generate data to embed and find pixels most probably invisible under modifications. We also show the experimental results of proposed algorithm.
