Robust watermarking scheme for copied, rotated and clipped documents
Kurato Maeno, Masayuki Suto (Oki)
Abstract (in Japanese) (See Japanese page) 
(in English) With the recent enactment of Privacy Protection Law in Japan, there has been an increasing interest in technologies for deterring information leakage in a variety of different areas. One of these technologies for deterring leakage allows users to control copiers or identify perpetrators when such incidents occur by watermarking information about who printed the document on the printed-paper. In this paper, we propose a watermarking scheme that enables synchronization on printed documents using correlation between 2-dimensional synchronization codes, in which Gabor filters are used for pattern detection. The experimental results indicated that, compared to traditional schemes, our watermarking scheme is much more effective for deterring information leakage by enabling higher robustness against copying, rotating and clipping of documents while preserving image quality.
