This book discusses the development and evaluation of blind, robust and fragile watermarking algorithms for ownership copyright protection and content authentication of digital satellite imagery using discrete cosine transform, discrete wavelet transform and hash function. The Index mapping technique used for color logo watermark and the best hiding location selection technique is used to embed the watermark in discrete cosine transform domain. The watermarking algorithms are causing a minimal invisible distortion to digital satellite imagery and assessed by using peak signal to noise ratio (PSNR) and structural similarity index measurement (SSIM), while the performance of the extracted watermark is analyzed using normalized correlation (NC). The robust watermark survived many intentional and non-intentional attacks; while the fragile watermark is very sensitive and any tampering to the watermarked imagery could be accurately detect the precise location of tampered area.
