TLDR
A novel logo watermarking framework is proposed using non-linear chaotic map to generate keys to be used in the embedding process, which reveals the efficiency and robustness of the proposed framework.Abstract:
In this paper, a novel logo watermarking framework is proposed using non-linear chaotic map. The essence of proposed technique is to use chaotic map to generate keys to be used in the embedding process. Therefore, a method for generating keys is first proposed followed by the embedding process. A robust extraction process is then proposed to verify the presence of watermark from the possibly attacked watermarked image. Experimental results and attack analysis reveal the efficiency and robustness of the proposed framework.read more

Rotation, scale and translation invariant spread spectrum digital image watermarking
TL;DR: In this paper, a Fourier-Mellin-based approach is used to construct watermarks which are designed to be unaffected by any combination of rotation and scale transformations, and a novel method of CDMA spread spectrum encoding is introduced which allows one to embed watermark messages of arbitrary length and which need only a secret key for decoding.
