Abstract

This paper presents a robust digital image watermarking scheme based on subsampling and DWT. Subsampling is firstly used to construct a subimage sequence as a video segment. Then, a random watermark sequence satisfied with Gaussian distribution is block-wised embedded into the DWT domain of these subimages repeatedly using the video watermarking technique. And watermark is detected through computing correlation between watermark and watermarked frames. The experiment results demonstrate that the proposed scheme achieves good robustness against JPEG compression, common image processing operation and geometric distortions. Furthermore, the proposed watermarking scheme is also robust against linear collusion and other video watermarking attacks.

Robust digital image watermarking based on subsampling

Applied Mathematics and Computation, 2006

This paper presents a robust digital watermarking scheme for copyright protection of digital images. Four subimages are obtained from the host image by using subsampling. A binary watermark image is permutated using chaotic map and then is embedded into the DCT coefficients of two of the subimages which are selected according to a random coordinates sequence generated by a secret key. Watermark extraction is simply by comparing the DCT coefficients of the watermarked subimages and does not need original image. Experimental results show good robustness and security of the proposed scheme.

A Novel DWT based Video Watermarking Scheme using Selective Column in Frames
IJSTE - International Journal of Science Technology and Engineering

One of the most secure and efficient method of video authentication is to watermark the video which is known as the video watermarking. Earlier watermarking is used in authentication of text and image later on this is extended to the video sequence as well. In this paper, an attempt has been done to design an efficient and secure watermarking method for protecting the video from unauthorized access. In the proposed method column from each frame are randomly selected to form a new frame which is used for embedding the watermark after DWT operation. Experimental results reveal that the proposed method is able to produce least distortion in the video sequence by keeping the watermark in the video secure.

DWT Based Digital Watermarking Technique and its Robustness on Image Rotation, Scaling, JPEG compression, Cropping and Multiple Watermarking
Alamgir Hossain

2007 International Conference on Information and Communication Technology, 2007

attempts to remove or destroy the watermark in time We propose in this paper a Discrete Wavelet domain cannot be easily done. Due to some Transform (DWT) based digital image techniques in the frequency domain [2], [3] they watermarking technique. For embedding process, we required the original image. Among the methods consider the watermark signal as a binary sequence which do not use the original image for watermark which is embedded to the high (HL and HH) detection, Piva et al. [5] suggested adding the frequency band of the blue channel. For detecting watermark to a larger number of DCT coefficients process, the correlation between the high frequency which need not be significant. A larger number of band DWT coefficients of the watermarked image coefficients are here for a significant detector and the watermark signal is compared with the response as compared with the method in [2], since predefined threshold to determine whether the correlation is performed without subtracting out the watermark is present or not. The experimental original image. results show that the method is comparatively robust In this paper, we propose an image watermarking to several attacks such as rotation, scaling, JPEG technique based on DWT. In DWT the pixels when compression, cropping, and multiple watermarking. transformed are arranged from the most significant pixel to the least significant pixel i.e. DWT helps

Video Multiple Watermarking Technique Based on Image Interlacing Using DWT
Prof. Mohamed Zorkany

Digital watermarking is one of the important techniques to secure digital media files in the domains of data authentication and copyright protection. In the nonblind watermarking systems, the need of the original host file in the watermark recovery operation makes an overhead over the system resources, doubles memory capacity, and doubles communications bandwidth. In this paper, a robust video multiple watermarking technique is proposed to solve this problem.This technique is based on image interlacing. In this technique, three-level discrete wavelet transform (DWT) is used as a watermark embedding/extracting domain, Arnold transformis used as a watermark encryption/decryption method, and different types of media (gray image, color image, and video) are used as watermarks. The robustness of this technique is tested by applying different types of attacks such as: geometric, noising, format-compression, and image-processing attacks. The simulation results show the effectiveness and good performance of the proposed technique in saving system resources, memory capacity, and communications bandwidth.

Robust Digital Image Watermarking Based on Joint DWT-DCT
saeed amirgholipour

International Journal of Digital Content Technology and Its Applications, 2009

As one of the crucial problems in watermarking, robustness against geometric distortion and JPEG compression becomes more than challenging and problematic. In this paper, a robust and geometric invariant watermarking scheme using block histogram and intensity-level histograms is proposed. During watermark embedding procedure, we first compute the number of valid intensity-levels of the given image, and group the pixels into blocks of variable size such that each of which has the same number of intensity-levels. Thus the block histogram is generated for the given image. Then the intensity-level histogram of each block is modified according to the embedding bits of the watermark. During the extraction procedure, the block histogram and intensity-level histogram of each block in the watermarked image are generated in a similar manner and the watermark is decoded according to the distribution of the intensity-level histogram in each block. Experimental results show that the proposed scheme is highly robust against not only JPEG compression, but also geometric attacks and common signal processing such as median filtering. The comparison results also show that the proposed scheme outperforms the existing methods in terms of robustness.

A digital video watermarking technique based on identical frame extraction in 3-Level DWT
Tamanna Tabassum

2012 15th International Conference on Computer and Information Technology (ICCIT), 2012

Digital video watermarking was introduced at the end of the last century to provide means of enforcing video copyright protection. Video watermarking involves embedding a secret information in the video. In this paper, we proposed a digital video watermarking technique based on identical frame extraction in 3-Level Discrete Wavelet Transform (DWT). In the proposed method, first the host video is divided into video shots. Then from each video shot one video frame called identical frame is selected for watermark embedding. Each identical frame is decomposed into 3-level DWT, then select the higher subband coefficients to embed the watermark and the watermark are adaptively embedded to these coefficients and thus guarantee the perceptual invisibility of the watermark. For watermark detection, the correlation between the watermark signal and the watermarked video is compared with a threshold value obtained from embedded watermark signal. The experimental results demonstrate that the watermarking method has strong robustness against some common attacks such as cropping, Gaussian noise adding, Salt & pepper noise adding, frame dropping and frame adding.

A Robust Video Watermarking Technique using DWT, DCT, and FFT
Naved Alam

—Proposed technique is based on dwt, dct, fft, and svd. First video is converted into frames. Apply DWT on each frame that will convert it into four sub-band frequency ranges as LL, LH, HL, and HH. Apply again DWT on LL sub-band then it will divide as LL1, LH1, HL1, and HH1 sub band of LL band. After applying DWT at 2-level, apply SVD in LL1 Sub-band, DCT in LH1 and FFT in HH1 sub-band of LL band. Same process will be applied on watermark symbol/image. Embed both host frame and watermark image with some scaling factor 'α'. For watermarked video arrange all the decomposed matrices using inverse technique. Watermarked video will be generated. To proof of ownership watermarking extraction process would be follow. And for proofing robustness and security level of this watermarked technique watermarked video will be compared with original video. And NCC, PSNR, BER value would be calculated. I. INTRODUCTION Internet has become indispensible and thus the security and the privacy issue have come to the fore of the computing fraternity. These issues need to be addressed with utmost urgency and highest level of dedication. Watermarking addresses the privacy and security issues. Watermarking has helped not just in security but also in resolving numerous copyright and privacy issues, which became one of the most contentious issues while the expansion of internet. This proposal explores the state of art introduces a novel technique to tackle the elephant in the room. Watermarking techniques can be segregated on the basis of domain based, document based, Perception based and application based. Domain of watermarking technique is divided in to two parts such as on the basis of spatial domain and other is on the basis of frequency domain. In spatial domain watermarking, watermark is embedded by modifying the pixels value of the host image/ video directly. The main advantages of pixel based methods are that they are conceptually simple and have very low computational complexities and therefore are widely used in video watermarking where real-time performance is a primary concern. However, they also exhibit some major limitations. The need for absolute spatial synchronization leads to high susceptibility to de-synchronization attacks; lack of consideration of the temporal axis results in vulnerability to video processing and multiple frame collusion; and watermark optimization is difficult using only spatial analysis techniques. In frequency domain, the watermark is embedded for the robustness of the watermarking mechanism. There are three main methods of data transmission in frequency domain. as DCT DFT and DWT. The main strength offered by transforming domain techniques is that they can take advantage of special properties of alternate domains to address the limitations of pixel-based methods or to support additional features. Generally, transform domain methods require higher computational time. In transform domain technique, the watermark is embedded distributive in overall domain of an original data. Host video is first converted into frequency domain by transformation techniques. The transformed domain coefficients are then altered to store the watermark information. The inverse transform is finally applied in order to obtain the watermarked video. On the basis of document watermarking can be apply on Image, Text, Audio and Video. According to the human perception watermarking is divided in to two parts visible watermark media and invisible watermark media. Invisible watermark is further are of two types robust watermarking and fragile watermarking. For effective watermarking the watermarking techniques need to be imperceptible (watermark should not degrade the quality of multimedia), robust (after applying attacks quality of multimedia should not be degrade), and secure from various attacks. In Most of the watermarking techniques, the watermark is embedded into the frequency domain instead of the spatial domain for the robustness of the watermarking mechanism. Discrete Cosine Transformation (DCT), Discrete Fourier Transformation (DFT) and Discrete Wavelet Transformation (DWT) are the three main methods of data transformation in this domain. The main strength offered by transforming domain techniques is that they can take advantage of special properties of alternate domains to address the limitations of pixel-based methods or to support additional features.

Hybrid Approach for Robust Digital Video Watermarking
IJSRD Journal

With the growing popularity of internet and digital media, digital watermarking techniques have been developed to protect the copyright of multimedia objects such as text, audio, video, etc. So, we have proposed a hybrid video watermarking technique which takes the advantages of different transforms like DWT, DCT, SVD and Arnold Transform, which enhances more security and provides robustness to the watermark. In this paper method, video is divided into several groups of frames, and one of the frames is selected where watermark will be embedded. Before embedding watermark in a selected frame it will be pre-processed with Arnold Transform which will provide security to it. The selected plane of video frame are decomposed using DWT and high frequency band HH, middle frequency bands LH, HL are transformed with DCT. The DCT coefficients are SVD transformed which are embedded with corresponding transformed coefficients of watermarks along with Arnold Transform. The embedded watermark is extracted with inverse process of embedding. The proposed algorithm is tested with various video sequences using MATLAB 2013a. The distortion quality of original image and watermark is controlled by the Peak Signal to Noise Ratio, Signal to Noise Ratio and Mean square error of the watermarked frame with original frame.

A new optimized robust digital image watermarking scheme based on DWT
Science Park Research Organization & Counselling

In this paper, a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are mixed to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet transform, the watermark is extracted, without any need to have access to the original image. Robustness of the proposed algorithm was tested against the following attacks: JPEG2000 and old JPEG compression, adding salt and pepper noise, median filtering, rotating, cropping and scaling. The promising experimental results are reported and discussed.

A Robust Video Watermarking Scheme using DWT and DCT
Chenna Krishna

Digital data is easily available in the form of images and videos, over the internet. Consequently, the increased importance of digital content invites new challenges for securing the distribution of digital media. This paper addresses a unique, robust copyright protection scheme for videos. In this watermarking algorithm, the video frames are selected randomly from the reference frames of original host video. The embedding of digital signature, tag or data is carried out in the frequency domain. The high frequency bands i.e. LH and HL in the wavelet domain are selected on which DCT is applied. The mid frequency coefficients of these DCT coefficients are altered by low frequency coefficients of the watermark to be embedded. The watermark can be retrieved from the watermarked video by randomly selecting any reference frame. The proposed algorithm is more secure, robust and efficient because of use of DWT and DCT. The algorithm uses the HL and LH bands to add the watermark where the motion does not affect the quality of extracted watermark even if the video is subjected to different types of malicious attacks. The technique is tested for various attacks and stands out to be fairly acceptable and robust against a wide range of signal and video processing operations. The embedded video is of good quality with high PSNR. The technique shows efficient extraction of watermark with high PSNR of the retrieved watermark.

    Blind image watermarking technique based on differential embedding in DWT and DCT domains
    Khier Benmahammed

    EURASIP Journal on Advances in Signal Processing, 2015

    This paper presents a new blind and robust image watermarking scheme based on discrete wavelet transform (DWT) and discrete cosine transform (DCT). Two DCT-transformed sub-vectors are used to embed the bits of the watermark sequence in a differential manner. The original sub-vectors are obtained by the sub-sampling of the approximation coefficients of the DWT transform of the host image. During the extraction stage, the simple difference between the corresponding sub-vectors of the watermarked image, gives directly the embedded watermark sequence. Experimental results demonstrate that the proposed technique successfully fulfills the requirement of imperceptibility and provides high robustness against a number of image-processing attacks, such as JPEG compression, noise adding, low-pass filtering, sharpening, and bit-plane removal. Our scheme exhibits also an acceptable to good performance against some geometrical attacks such as resizing and cropping.

    Dynamic S-Box and PWLCM-Based Robust Watermarking Scheme
    sema kayhan

    Wireless Personal Communications, 2022

    Due to the increased number of cyberattacks, numerous researchers are motivated towards the design of such schemes that can hide digital information in a signal. Watermarking is one of the promising technologies that can protect digital information. However, traditional watermarking schemes are either slow or less secure. In this paper, a dynamic S-Box based efficient watermarking scheme is presented. The original image was extracted at the receiver’s end without any loss of sensitive information. Firstly, the Secure Hash Algorithm is applied to the original image for the generation of the initial condition. Piece Wise Linear Chaotic Map is then used to generate 16 $$\times$$ × 16 dynamic Substitution Box (S-Box). As an additional security feature, the watermark is substituted through dynamic S-Box. Hence, it is hard for the eavesdroppers to attack the proposed scheme due to the dynamic nature of S-Box. Lastly, lifting wavelet transform is applied to the host image and the High Lo...
