Abstract(in English) | We are developing an iPhone application which can embed a URL into a screenshot image of a web page by using digital watermarking techniques at taking screenshot. A lot of screenshots are taken on mobile devices as memos of some web pages. However, one cannot get the URLs of the web pages from the usual screenshot images. Those who want to see the web page have to search it again. In this work, we developed an iPhone application which can store the URL in a screenshot image at taking screenshot and then can retrieve the URL from the screenshot image. Each alphabet of URL is converted into a binary watermark. By using our application, one can easily see the web page from the screenshot image again. We examined that our application functioned correctly. Moreover, we evaluated the quality of screenshotimages and the bit error rate (BER) of watermarks. As a result, the BER was almost constant. Although the image quality became worse as the length of URL was larger, all PSNRs were over 40 dB. Therefore, our application could make good quality screenshot images. |
