| Abstract | ||
| The rapid development of the communication networks through the Internet and development of the electronic trade with spread of the digital media such as (images, audio, video) which can be got easily, copied, and distributed with other person names. All these led to the needs of the authentication or copyright. The most important techniques used are watermark techniques. The watermark techniques are divided into two types, they are 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 focus on the frequency domain and deals with the images by choosing the best locations to embed the watermark to ensure the digital watermarking requirements. | ||
