Watermarking is process of hiding digital information into another object/signal. To attain robustness information based on image data is transformed in multiple resolution using Wavelet based image watermarking methods. Embedding watermark bits in middle frequency sub images in the wavelet domain is done using Multiband Wavelet Transform (MWT). At this juncture an attempt is made to analyze robustness for different test images. To resist various attacks Empirical Mode Decomposition (EMD) is used. Performance evaluation of an Image watermarking includes robustness, imperceptibility, watermark capacity and security.

Traditional watermark embedding introduces inevitably some perceptible quality degradation of the host image. Another problem is the inherent conflict between imperceptibility and robustness. However, the zero-watermarking technique can extract some essential characteristics from the host image and use them for watermark registration and detection. The original image was decomposed into series of multiscale and directional subimages after lifting wavelet transformation (LWT). The high order bit-plane of low-frequency subimage and watermark image are inputs of the cellular neural network (CNN), and the zero-watermarking registration image is the output. To investigate and improve the security and robustness, the original watermark and registration image are scrambled or encrypted. The watermark image can be extracted from the secret image. This algorithm is simple and robust. The proposed method is also simple for hardware realization.

Anonymous multi-receiver encryption (AME) achieves the security properties of confidentiality and anonymity. Thus, it can be used in VoIP (Voice over Internet Protocol), pay-TV systems, et al. In 2012, Zhang et al. proposed an efficient anonymous multi-receiver encryption protocol. They claimed that their protocol can protect the receiver identity privacy and keep message confidential. In this paper, we point out the weaknesses of Zhang et al.'s protocol. Their protocol cannot satisfy the anonymity against the inner attackers. On the other hand, their AME protocol cannot satisfy the indistinguishability of encryptions under selective multi-identity, chosen ciphertext attacks (IND-AME-CCA). Thus, Zhang et al.'s protocol is insecure. The analysis is important for the engineer to mitigate the security risks.

In this paper, a robust and transparent watermarking scheme for color images is proposed. The color features for the human visual system are utilized to design the color watermarking algorithm. The basic idea is to embed the invisible watermark into the color image by brightness adjustment and feature component choice.

In this paper, a robust image watermarking method with S-Hough transformation is proposed which is robust against geometric distortion. This watermarking is detected by a linear frequency change. The chirp signals are used as watermarks and this type of signals is resistant to all stationary filtering methods and exhibits geometrical symmetry. In the two-dimensional Radon-Wigner transformation domain, the chirp signals used as watermarks change only its position in space/spatial-frequency distribution, after applying linear geometrical attack. But the two-dimensional Radon-Wigner transformation needs too much difficult computing.

The proposed scheme can resolve the time-frequency localization in a better way than the standard Dopplerlet transformation. The watermark is embedded in the 1D improved Dopplerlet transformation domains. The watermark thus generated is invisible and performs well in test and is robust to geometrical attacks. Compared with other watermarking algorithms, this algorithm is more robust, especially against geometric distortion, while having excellent frequency properties.
