This paper presents a new semi-blind image watermarking system for medical applications. The new scheme utilizes Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT) to embed a textual data into original medical images. In particular, text characters are encoded by a Quadrature Amplitude Modulation (QAM-16). In order to increase the security of the system and protect then the watermark from several attacks, the embedded data is submitted to Arnold Transform before inserting it into the host medical image. To evaluate the performances of the scheme, several medical images have been used in the experiments. Simulation results show that the proposed watermarking system ensures good imperceptibility and high robustness against several attacks.

Steganography is the technique that communicates secret data in different carriers like image, audio files etc. in such a way that it is not be visible to attackers. In this paper, performance analysis of image steganography based on Discrete Wavelet Transform (DWT) associated to colored and gray scale images is done. Arnold transformation along with a private key is used during encoding to provide high security. DWT is applied on both the cover image and the secret image and then alpha blending operation is done. Stego-image is obtained by using Inverse Discrete Wavelet Transformation (IDWT) Performance analysis is done by using different wavelet families. The simulation results show that PSNR values of the Arnold Transform based method are better than existing methods.

Internet has made so easy to transfer the large amount of data in different parts of the world. So, the security and safety of information has become the major concern. This problem has led to the development of steganography techniques. This paper deals with data hiding technique in which the secret data is embedded into the cover video. Firstly, cover video is decomposed into different frames. A single level Discrete Wavelet transform is applied on selected frame and on secret image. A private key is used during the process of encoding and decoding to provide high security. Then the Inverse Discrete Wavelet Transformation (IDWT) is applied to get the stego-video. The performance parameters like Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) can be calculated to determine the quality of stego video. The results show that the proposed algorithm for steganography is highly secured with good perceptual invisibility.
