Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In concern to the growth of high-speed computer network and that of the Internet, Digital media offer several advantages over analog media like high quality, easy editing, high fidelity, copying. There are emerged as a protection tool in which data is hidden in an image, audio or video file. Watermark is to hide information in cover image. It is reliable digital image watermarking. It provides high imperceptibility and robustness for copyright protection. Two methods are proposed in this dissertation work, first method is the combination of Discrete Wavelet Transform, Singular Value Decomposition, and Discrete Cosine Transform. It is a robust watermark. In this a multi-channel image watermarking technique is used. It means multiple watermarks are embedded in the image. In this method, initially first level of three watermark images are embedded in the second RGB watermark image and then this second level RGB image watermark is embedded in the RGB cover image to obtain the watermarked image. This process increases the robustness of watermark. 96 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Image compression plays an essential role in the data transmission and data storage. To limit the redundancy of the image, furthermore storage and transmit the information in an effective form is the prime objective of the image compression. Generally, image compression is referred to minimize the number of bits expected to signify an image. With the help of the secret key, concealing the image from an unauthorized access is known as image encryption in that the key can be private or public. With the developing number of images, real-time interactions with the compressed images, their sizes, and variety of their bandwidths, the transmission of the digital images are as yet difficult. Additionally, giving security to images to resist from different data integrity and security attacks is the primary issue of image encryption. To overcome these issues in the image compression and the image encryption a few novel techniques are proposed. Furthermore, the proposed techniques are to provide greater complexity against hackers and it takes less time for the encryption. 180 pp. Englisch.
