“…The strength of this technique is based on its ability to take advantage of special properties of domain alternation to address the limitation of pixel based technique [9]. Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Discrete Fourier Transform (DFT) are the three main techniques of transforming the data in frequency domain [10].…”

This paper presents the performance evaluation of a developed multiple transform watermarking system for privacy protection of medical data using Peak Signal to Noise Ratio (PSNR) and Normalized Cross-Correlation (NC). The PSNR was used to evaluate the imperceptibility of the system, while the NC was used to evaluate the robustness of the system under the various attacks include: Gaussian noise, pepper and salt noise, sharp enhancing, image cutting, image compression, low pass filter and image rotation. The obtained result showed that the similarity between original image and watermarked image has PSNR of 52.4595dB as compared to the existing system of 50.0285dB. This indicates that the proposed scheme can conceal the watermark better, and as well retains the image quality.

“…Due to the quick and large development of transmission and additionally the widespread use of information superhighway, there is a want for economical, powerful and effective techniques to protect data [1]. Completely different watermarking techniques are developed in special and remodel domain strategies, however, in recent years; the watermarking techniques supported remodel domain ar developed to produce higher lustiness and physical property.…”

Hiding an image in another image is the technique used for copy write protection. In this proposed work, the watermark is inserted into blue plane of the cover image, In this watermark extraction and embedding process, the back propagation neural network in conjunction with biorthogonal wavelets is utilized to improve the efficiency. The performance is tested by normalized correlation coefficient. The imperceptibility of the watermark is tested by cropping and rotation attacks effectively

Image watermarking is an important application of the image processing .Image watermarking is the process of inserting the watermarked message in a host document in some multimedia format. Watermarking presents the basic model for embedding and extraction of watermark. It is basically required to protect the information from the unauthorized access. The copyright protection, capacity, security, robustness etc are some of the important factors that are taken in account while the watermarking system is designed. This paper presents study of the digital watermarking process, concept, applications and its contributions in various other fields.
