Abstract

One negative side of the digital era is the including document forgery. To reduce this, we may use images or logo to show the owner of the document. This method isn’t effective, since the document can be easily duplicated by photocopy machine. During the photocopy process, the image/logo may easily be removed from the document. This research trying to solve the problem above by developing a system to embed dynamic transparent text based watermark inside an digital image, thus reducing the document forgery. The process divided into four steps, which are grayscaling, generating watermark, edge detection and embedding process. The software tested using several font to find the best font to use. Thick font generate the best watermark, because thick font will produce clear and sharp edge. The watermarked image quality is good because the embedded watermark doesn’t ruin the image quality.
