The validation of images taken by digital cameras has become a great concern as the digital photography is gaining rapid popularity. So, due to lack of protection of digital content as they can be easily duplicated and disseminated without the owner's consent , publishers, artists, and photographers, however, are unwilling to distribute images or other data over the Internet. Therefore, to protect confidential images we propose an efficient digital watermarking technique to deal with this difficult issue. In the proposed technique, the image is first converted into YCbCr from RGB domain then watermark is embedded in Y component of YCbCr using Discrete Wavelet Transform and Singular ValueDecomposition (SVD). The results show that our algorithm is resistant toward various attacks.

This paper adopted a new video watermarking scheme based on hybrid transforms to achieve the watermarking requirements, that is, robustness, imperceptibility, and security. Where In our system first of all, the original video will be divided into frames to transform it using the Slantlet Transform into four sub-bands (i.e., LL, LH, HL, and HH). Secondly, The HL sub-band will be chosen for further decomposition using Contourlet Transform (CT), and then the low subband of CT will be selected to decompose it to fixed size non overlapping blocks to employ the DCT (Discrete Cosine Transform) on each block. lastly, to improve the security and robustness, the watermark logo is scrambled using AT(Arnold transformation ) as a prelude to embed it's on the each transformed nonoverlapping blocks. Experimental results show that the proposed system achieves good imperceptibility and high resistance against various attacks.

Transformation is one of the fundamental blocks of many signal processing applications. The Hadamard transform is useful in variety of application including data encryption methods and latest data compression algorithms such as JPEG extended range (JPEG XR), High Efficiency Video Coding (HEVC) etc. Hadamard transform is multiplier less technique and requires additions and subtractions only. In this paper, we have proposed an efficient method of 4 and 8 points Hadamard transformation using a parallel processing to achieve higher speed. The 8-point DHT has been realized with 4 points DHT implementation. The modules are synthesized using Xilinx ISE 14.2 software with the usage of inbuilt memory core generator for storing co-efficient values. The performance has been verified with area and timing analysis. The proposed implementation shows excellent results and also compared to previous works.
