DOI:, Pub. Date: 8 Aug. 2015

Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) based techniques have become prominently used in watermarking research. DCT based technique replacing the older ones have made digital watermarking based e-commerce a part of almost all business transactions. It is also being used in business communications and different solutions through computer network. DCT based technique is considered as a secured communication between two users. Verification is being provided for the origin of a watermark that traverses from sender to receiver. The cost per transmission has also reduced as the watermark is encoded in the digital watermarking itself. Here the key size is also small thus making it suitable for key exchange application. Also the security level in fragile watermark is better compared to discrete data integrity verification or authentication for the same bandwidth and key size In this paper, we have compared various geometric attacks based techniques in terms of PSNR and Attack Recovery time.
