Digital Video Watermarking Using Discrete Cosine Transform and Perceptual Analysis

Due to the extensive use of digital media applications, multimedia security and copyright protection has gained tremendous importance. Digital Watermarking is a technology used for the copyright protection of digital applications. In this paper, a comprehensive approach for watermarking digital video is introduced. We propose a hybrid digital video watermarking scheme based on Discrete Cosine T...

Digital image Watermarking using Two Dimensional Discrete Wavelet Transform, Discrete Cosine Transform and Fast Fourier Transform

Abstract—In digital watermarking, a watermark is embedded into a cover text in such a way that the resulting watermarked signal is robust to certain distortion caused by either standard data processing in a friendly environment or malicious attacks in an unfriendly environment. This paper presents a digital image watermarking based on two dimensional discrete cosines transform (DCT2), two dimen...

Watermarking of Images in Discrete Cosine transform

Data embedding is simplest technique to achieve the secret data sharing information. Now days a color image is a very popular to consider cover image medium used to send the secret data. I have proposed an approach for hiding a secret image in a cover image. In the beginning, the DCT [8] of image is computed that is compress the secret image, and then encrypt cover data by DES. Various authors ...

Digital Image Watermarking Technique Using Discrete Wavelet Transform And Discrete Cosine Transform

Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document. In this paper a new watermarking technique to add a code to digital images is presented: the method operates in the frequency doma...

Quantization-Based Digital Audio Watermarking in Discrete Fourier Transform Domain

To explore the principle and performances of Quantization Index Modulation (QIM) watermarking algorithm, the realization schemes of this algorithm in Discrete Fourier Transform (DFT) domain are classified into three types according to the differences of quantizer parameters, and then the illustrative diagrams of these schemes are given, so the properties of transparency, robustness and capacity...
