Abstract (in Japanese) (See Japanese page) 
(in English) We propose a smear transform digital image watermarking based on sign information.This method increases amount of embedded information using sign information of signatures.It improves quality of watermark images by embedding signatures to areas where dynamic range is reduced by wavelet transform.This method has a high signature rate of detection due to synchronous addition when detect signatures.In the computer experiment, the proposed method increases amount of embedded information without losing the quality of watermark images.
