By embedding electronic watermarks (ex. QR codes) in advertisement such as digital signage, we can get additional information through the Internet by translating the electronic watermark into URL. Usually digital images in digital signage are composed of JPEG images. It is well known that electric watermarks deteriorate deeply if we embed them into JPEG images. It results in algorithm of JPEG compression. In this study, we try two methods as follows; (1) masking effect, and (2) embedding plural electric watermarks. Then, estimation and remained problems are shown.
