Abstract
Satellite images and raster data with valuable information are expensive and important. The security of these images is of concern in todays networked environment where data can be distributed and copied easily. Moreover, these data-sets are quite complex in nature and not many robust watermarking techniques have been proposed to deal with these issues. This paper is an attempt to develop a robust watermarking algorithm for Raster data-sets of Satellite Images. Though robustness is necessary to resist external attacks on satellite data, the presence of fragile watermarks in data should also be considered to detect tampering and even locate the area of attack. The proposed algorithm, Texture based LSB and DWT, is tested against attacks such as smoothing and contrast enhancement. The results and analysis are discussed for the same.
