| Abstract | ||
| The advent of the Internet has resulted in many new opportunities for the creation and delivery of content in digital form. Applications include electronic advertising, real time video and audio delivery, digital repositories, libraries, and Web publishing. An important issue that arises in these applications is the protection of the rights of digital data. One such effort that has been attracting increasing interest is based on digital watermarking techniques. The watermark techniques are divided into two types, spatial domain and frequency domain techniques. The frequency domain techniques are more stronger than the spatial domain techniques. The proposed algorithm is used with Discrete Cosine transform (DCT). Several experiments were given to illustrates the performance of the proposed scheme. This research focuses on the frequency domain and deals with the images by choosing the best locations to embed the watermark to ensure the digital watermarking requirements. | ||
