SECURED COLOR IMAGE WATERMARKING TECHNIQUE IN DWT-DCT DOMAIN ijcseit
The multilayer secured DWT-DCT and YIQ color space based image watermarking technique with
robustness and better correlation is presented here. The security levels are increased by using multiple pn
sequences, Arnold scrambling, DWT domain, DCT domain and color space conversions. Peak signal to
noise ratio and Normalized correlations are used as measurement metrics. The 512x512 sized color images
with different histograms are used for testing and watermark of size 64x64 is embedded in HL region of
DWT and 4x4 DCT is used. ‘Haar’ wavelet is used for decomposition and direct flexing factor is used. We
got PSNR value is 63.9988 for flexing factor k=1 for Lena image and the maximum NC 0.9781 for flexing
factor k=4 in Q color space. The comparative performance in Y, I and Q color space is presented. The
technique is robust for different attacks like scaling, compression, rotation etc.
DWT-SVD Based Visual Cryptography Scheme for Audio Watermarkinginventionjournals
Secured access to the Internet and data resources has a high impact in defense system. This dependency has brought many threats to information security. As aresult, reliably secure mechanisms are required to protect most untold and blueprint of defenseinformation against vulnerabilities like ID spoofing and unauthorized access to top most system of country. In this paper, we proposed algorithm based on audio watermarking using DWT-SVD algorithm with visually crypted image message. The army people may have access to listen radio and communicate through walkie talkie which is audio format data. In proposed work we are hiding visually crypted image massage in audio file which may decrypted by proving shared image and extracted watermark image without affecting original audio. We did comparative analysis of various attacks on audio file after watermarking and calculated robustness and SNR value to support out work.
Multiple Binary Images Watermarking in Spatial and Frequency Domainssipij
Editing, reproduction and distribution of the digital multimedia are becoming extremely easier and faster with the existence of the internet and the availability of pervasive and powerful multimedia tools. Digital watermarking has emerged as a possible method to tackle these issues. This paper proposes a scheme using which more data can be inserted into an image in different domains using different techniques. This increases the embedding capacity. Using the proposed scheme 24 binary images can be embedded in the DCT domain and 12 binary images can be embedded in the spatial domain using LSB substitution technique in a single RGB image. The proposed scheme also provides an extra level of security to the watermark image by scrambling the image before embedding it into the host image. Experimental results show that the proposed watermarking method results in almost invisible difference between the watermarked image and the original image and is also robust against various image processing attacks.
Image denosing in underwater acoustic noise using discrete wavelet transform ...TELKOMNIKA JOURNAL
In many applications, Image de-noising and improvement represent essential processes in presence of colored noise such that in underwater. Power spectral density of the noise is changeable within a definite frequency range, and autocorrelation noise function is does not like delta function. So, noise in underwater is characterized as colored noise. In this paper, a novel image de-noising method is proposed using multi-level noise power estimation in discrete wavelet transform with different basis functions. Peak signal to noise ratio (PSNR) and mean squared error represented performance measures that the results of this study depend on it. The results of various bases of wavelet such as: Daubechies (db), biorthogonal (bior.) and symlet (sym.), show that denoising process that uses in this method produces extra prominent images and improved values of PSNR than other methods.

Embedding information so that it cannot be visually perceived. Embedding information in digital data so
that it cannot be visually or audibly perceived. In this paper we review some of the digital image
watermarking and techniques and then DFT algorithm is also proposed. In this paper we review the
robustness and metrics.
In Digital era sharing of images have become very
common and raises the risk of using it for unethical and
fraudulent purposes with the help of manipulation tools. Digital
image watermarking is one way to protect the digital information
(text, images, audio, and video) from fraudulent manipulations.
Digital Image Watermarking is a process of implanting data in
the original image for authentication. In this paper we are
providing one such watermarking scheme for color images. The
proposed method is designed to be robust for common attacks
with the aid of redundant discrete wavelet transform (RDWT)
and discrete cosine transform (DCT) properties. After applying
two levels RDWT decomposition to the blue channel of cover
image, we apply DCT to HH_LL subband i.e. 2nd level
decomposed coefficient of HH band and to the watermark.
Divided the HH_LL sub band into 4x4 subblocks and DCT
coefficients of the last subblock of the cover image are replaced
with the DCT coefficients of watermark. Inverse DCT and
inverse RDWT is performed to get watermarked image. The
performance of the proposed technique is measured using the
parameters PSNR and NCC.
An Efficient Video Watermarking Using Color Histogram Analysis and Biplanes I...IJERA Editor
Video watermarking is a novel technology that has the ability to solve the problem of illegal digital video
manipulation and distribution. In video watermarking, the copyright bits are embedded into video bit streams.
This paper proposes an effective, robust and indiscernible video watermarking algorithm. A video can also
undergo several intentional attacks like frame dropping, averaging, cropping and median filtering and
unintentional attacks like addition of noise and compression which can compromise copyright information,
thereby denying the authentication. In this paper, the design and implementation of SVD and multiple bit plane
image based watermarking is proposed. The developed method embeds 8 bit-plane images, obtained from single
gray scale watermark image, into different frames of a video sequence. In this algorithm, some of the luminous
values in the video pictures are selected and divided into groups, and the watermark bits are embedded by
adjusting the relative relationship of the member in each group. A sufficient number of watermark bits will be
embedded into the video pictures without causing noticeable distortion. The watermark will be correctly
retrieved at the extraction stage, even after various types of video manipulation and other signal processing
attacks.
This slide gives you the basic understanding of digital image compression.

Digital watermarking with a new algorithmeSAT Journals
Abstract Everyday millions of data need to transmit through a distinct channel for various purposes; as a result there is a certain chance of third person interruption on that data. In this regards digital watermarking is one of the best solution. This paper proposes a new embedding algorithm (NEA) of digital watermarking. The algorithm is performed for digital image as data. The performance is compared for NEA and well established Cox's modified embedding algorithm. The watermarking is based on discrete wavelet transforms (DWT) and discrete cosine transforms (DCT). The acceptance of the new algorithm is measured by the two requirements of digital watermarking. One is imperceptibility of the watermarked image, measured by peak signal to noise ratio (PSNR) in dB; another one is robustness of the mark image, measured by correlation of original mark image and recovering mark image. Here a 512×512 gray scale "Lena" and "Cameraman's" image is taken as host images, and a 128×128 gray scale image is taken as mark image for 2 level of DWT. The simulation results for different attacking conditions such as salt and pepper attack, additive white Gaussian noise (AWGN) attack, jpg compression attack, gamma attack, histogram attack, cropping attack, sharpening attack etc. After different attacks the changing tendency PSNR for both algorithms are similar. But the mean square error (MSE) value of NEA is always less than Cox’s modified algorithm, which means that after embedding the changes of the host image property lower for NEA than Cox’s algorithm. From the simulation results it can be said that NEA will be a substitute of modified Cox’s algorithm with better performance. Keywords: Digital watermark, DWT, DCT, Cox’s modified algorithm, Lena image, Cameraman image, AWGN, JPG, salt and pepper attack, PSNR, correlation, MSE.

Hybrid Digital Image Watermarking using Contourlet Transform (CT), DCT and SVDCSCJournals
Role of watermarking is dramatically enhanced due to the emerging technologies like IoT, Data analysis, and automation in many sectors of identity. Due to these many devices are connected through internet and networking and large amounts of data is generated and transmitted. Here security of the data is very much needed. The algorithm used for the watermarking is to be robust against various processes (attacks) such as filtering, compression and cropping etc. To increase the robustness, in the paper a hybrid algorithm is proposed by combining three transforms such as Contourlet, Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD). Performance of Algorithm is evaluated by using similarity metrics such as NCC, MSE and PSNR.
Comparison of SVD & Pseudo Random Sequence based methods of Image Watermarkingijsrd.com
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. Image watermarking is used to hide the special information into the image and to later detect and extract that special information. Watermarking can be implemented both in spatial and frequency domain. In this paper frequency domain techniques were experimented. The methods compared in this paper are image watermarking using singular value decomposition (SVD) based and image watermarking using discrete wavelet transform (DWT) and Pseudo random sequence. Our experiments show that former technique have low peak signal to noise ratio (PSNR) value and also requires cover data at the detection where as in the later case we don’t require cover data and PSNR value is good.

In this paper an efficient & robust non-blind watermarking technique based on multi-resolution geometric analysis named curvelet transform is proposed. Curvelet transform represent edges along curve much more efficiently than the wavelet transform and other traditional transforms. The proposed algorithm of embedding watermark in different scales in curvelet domain is implemented and the results are compared
using proper metric. The visual quality of watermarked image, efficiency of data hiding and the quality of extracted watermark of curvelet domain embedding techniques with wavelet Domain at different number of decomposition levels are compared.

Ijri ece-01-02 image enhancement aided denoising using dual tree complex wave...Ijripublishers Ijri
This paper presents a novel way to reduce noise introduced or exacerbated by image enhancement methods, in particular
algorithms based on the random spray sampling technique, but not only. According to the nature of sprays,
output images of spray-based methods tend to exhibit noise with unknown statistical distribution. To avoid inappropriate
assumptions on the statistical characteristics of noise, a different one is made. In fact, the non-enhanced image is
considered to be either free of noise or affected by non-perceivable levels of noise. Taking advantage of the higher sensitivity
of the human visual system to changes in brightness, the analysis can be limited to the luma channel of both the
non-enhanced and enhanced image. Also, given the importance of directional content in human vision, the analysis is
performed through the dual-tree complex wavelet transform , lanczos interpolator and edge preserving smoothing filters.
Unlike the discrete wavelet transform, the DTWCT allows for distinction of data directionality in the transform space.
For each level of the transform, the standard deviation of the non-enhanced image coefficients is computed across the
six orientations of the DTWCT, then it is normalized.
Keywords: dual-tree complex wavelet transform (DTWCT), lanczos interpolator, edge preserving smoothing filters.

Digital Image Watermarking Based On Gradient Direction Quantization and Denoi...IJERA Editor
Digital watermarking is the art of hiding of information or data in documents, where the embedded information
or data can be extracted to resist copyright violation or to verify the uniqueness of a document which leads to
security. Protecting the digital content has become a major issue for content owners and service providers.
Watermarking using gradient direction quantization is based on the uniform quantization of the direction of
gradient vectors, which is called gradient direction watermarking (GDWM). In GDWM, the watermark bits are
embedded by quantizing the angles of significant gradient vectors at multiple wavelet scales. The proposed
scheme has the advantages of increased invisibility and robustness to amplitude scaling effects. The DWT
coefficients are modified to quantize the gradient direction based on the on the derived relationship between the
changes in the coefficients and the change in the gradient direction. In this paper, we propose a novel explicit
image filter called guided filter. It is derived from a local linear model that computes the filtering output using
the content of guidance image, which can be the input image itself or any other different image. The guided
filter naturally has a fast and non approximate linear time algorithm, regardless of the kernel size and the
intensity range. Finally, we show simulation results of denoising method using guided image filtering over
bilateral filtering

A novel rrw framework to resist accidental attackseSAT Journals
Abstract Robust reversible watermarking (RRW) methods are popular in multimedia for protecting copyright, while preserving intactness of host images and providing robustness against unintentional attacks. Robust reversible watermarking (RRW) is used to protect the copyrights and providing robustness against unintentional attacks. The past histogram rotation-based methods suffer from extremely poor invisibility for watermarked images and limited robustness in extracting watermarks from the watermarked images destroyed by unintentional attacks. This paper proposes a wavelet-domain statistical quantity histogram shifting and clustering (WSQH-SC) method and Enhanced pixel-wise masking (EPWM). This method embeds a new watermark image and extraction procedures by histogram shifting and clustering, which are important for improving robustness and reducing run-time complexity. It is possible reversibility and invisibility. By using WSQH-SC methods reversibility, invisibility of watermarks can be achieved. The experimental results show the comprehensive performance in terms of reversibility, robustness, invisibility, capacity and run-time complexity widely applicable to different kinds of images. Keywords: — Integer wavelet transform, k-means clustering, masking, robust reversible watermarking (RRW)
Noise resistance territorial intensity-based optical flow using inverse confi...journalBEEI
This paper presents the use of the inverse confidential technique on bilateral function with the territorial intensity-based optical flow to prove the effectiveness in noise resistance environment. In general, the image’s motion vector is coded by the technique called optical flow where the sequences of the image are used to determine the motion vector. But, the accuracy rate of the motion vector is reduced when the source of image sequences is interfered by noises. This work proved that the inverse confidential technique on bilateral function can increase the percentage of accuracy in the motion vector determination by the territorial intensity-based optical flow under the noisy environment. We performed the testing with several kinds of non-Gaussian noises at several patterns of standard image sequences by analyzing the result of the motion vector in a form of the error vector magnitude (EVM) and compared it with several noise resistance techniques in territorial intensity-based optical flow method.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

--------------------------------------------------------ABSTRACT-------------------------------------------------This paper presents a robust watermarking technique using discrete wavelet transform and Singular Value
Decomposition. In proposed method the blue channel of the color host image is selected for embedding
watermark because it is more resistant to changes compared to red and green channels, for embedding
watermark singular values are used. In this the watermark is embedded into singular values of the host image.
They embedded the singular values of the watermark image into the singular values of the host image. The blue
channel is decomposed into n levels using discrete wavelet transform because this is an invertible transform and
has the property of exact reconstruction and smoothness. This method is shown to be robust against many signal
processing operations as well as geometrical attacks.

--------------------------------------------------------------------------------------------------------------------------I . INTRODUCTION
With the growth of the Internet and the immediate availability of computing resources to everyone,
“digitized property” can be reproduced and instantaneously distributed without loss of quality at basically no
cost. Until now, intellectual property and value has always been bound to some physical container that could not
be easily duplicated, there by guaranteeing that the creator benefits from his work. Clearly, there is business like
the music or photography industry that cannot adopt this paradigm since they trade basic content and therefore
have to stick with traditional copyright enforcement to guarantee income. As audio, video and other works
become available in digital form, it may be that the ease with which perfect copies can be made will lead to
large-scale unauthorized copying which will undermine the music, film, book and software publishing
industries. The rapid evolution of digital technology makes the development of reliable and robust schemes for
protecting digital still images, audio and video from piracy a matter of urgency. The use of digitally formatted
image and video information is rapidly increasing with the development of multimedia broadcasting, network
databases and electronic publishing. This evolution provides many advantages such as easy, fast and
inexpensive duplication of products. However, it also increases the potential for unauthorized distribution of
such information, and significantly increases the problems associated with enforcing
Copyright protection.
II . 2D DISCRETE WAVELET TRANSFORM
The 2D DWT is computed by performing low-pass and high pass filtering of the image pixels as shown
in Figure 1. In this figure, the low-pass and high-pass filters are denoted by h (n) and g (n), respectively. This
figure depicts the one level of the 2D DWT decomposition. At each level, the high-pass filter generates detailed
image pixel information, while the low-pass filter produces the coarse approximations of the input image. At the
end of each low-pass and high-pass filtering, the outputs are down-sampled by two (↓ 2). In order to compute
2D DWT, 1D DWT is applied twice in both horizontal and vertical dimension. In other words, a 2D DWT can
be performed by first performing a 1D DWT on each row, which is referred to as horizontal filtering, of the
image followed by a 1D DWT on each column, which is called vertical filtering as shown in figure 1.

Fig.2. Two level 2D Wavelet based transforms
The higher level sub bands are more significant than the lower level sub bands. They contain most of
the energy coefficients so embedded in higher level sub bands is providing more robustness. On the other hand
lower level sub bands have minor energy coefficients so watermark in these sub bands are defenseless to
attacks. The higher level approximation sub band (LL2 sub band) is not suitable for embedding a watermark
since it is a low-frequency band that contains important information about an image and easily causes image
distortions. In second level, embedding a watermark in the diagonal sub band (HH2 sub band) is also not
suitable, since the sub band can easily be eliminated, for example by lossy compression as it has minor energy
coefficient. So the middle frequency sub bands (Vertical & Horizontal) of higher level are the best choice for
embedding. Further the LH2 sub band has more significant coefficients than the HL2 sub band.
III PERFORMANCE EVALUATION
Peak Signal-to-Noise Ratio (PSNR): It is the ratio between the maximum possible power of a signal
and the power of corrupting noise the affects the fidelity of its representation. It is the most easily defined via
the Mean Squared Error (MSE) which for two m x n images I and K where one of the images is considered as a
noisy approximation of the other. MSE and PSNR can be estimated below equations.

IV PROPOSED WATERMARKING METHOD
In embedding process, first separate the R, G & B channels of the color image and the blue channel is
selected for the embedding because this channel is more resistant to changes compared to red and green
channels and the human eye is less sensitive to the blue channel, a perceptually invisible watermark embedded
in the blue channel can contain more energy than a perceptually invisible watermark embedded in the luminance
channel of a color image. The blue channel is decomposed into n-level using discrete wavelet transform
Let select a bmp image of size 128 x 128 as watermark and convert it into a 1-D vector, for embedding
watermark bit 0 & 1 in mid frequency sub bands of higher level decomposition of the channel. Finally
reconstruct the watermarked image using inverse discrete wavelet transform. Now calculate the Mean Squared
Error & Peak Signal to Noise Ratio between original host image and watermarked image to evaluate the
perceptual Similarity between these two images by using equation 1 & 2.
In extraction process the end user separates the R, G & B channels of the watermarked image. The blue
channel is decomposed into n-level using discrete wavelet transform.

V SINGULAR VALUE DECOMPOSITION
SVD is a Mathematical tool used to analyze matrices. In this a square matrix is decomposed into three
matrices of same size. A real matrix A of size NxN can be decomposed into a product of three matrices.
A= USVT
Where U and V are left singular and right singulars vectors of A and S is diagonal matrix.
For calculating singular values, we need to find DET of the matrix, Eigen values, Eigen vectors and
inverse transform after that we can get the singular values. SVD is having so many properties like Orthogonal
matrices, Scaling property, The Stability of singular values, Rotation and translation invariance.
VI EXPERIMENTAL RESULTS

128X128 is chosen as a watermark. Figure 3 shows the original host image & l-Level decomposed blue channel

the receiver side is shown.

(c) α =0.01, MSE= 2.3376, PSNR=94.4430.
The performance of the proposed method is tested by applying different geometric and image
processing attacks, such as salt and pepper noise, Random noise, Rotation, Additive Gaussian noise, Gamma,
Blurring and Motion Blurring attack.

VII. CONCLUSION
In this paper a new robust watermarking technique for copyright protection has been proposed. We
applied the singular value decomposition along with the Discrete Wavelet Transform. Since the technique
utilizes the properties of both DWT and SVD the proposed technique is more robust against different attacks.
The innovation of this paper is that the security of the algorithm is increased with the on the watermark image.
The robustness of the technique is justified by giving analysis of the effect of attacks and still we are able to get
good visual quality of the embedded watermark. The performance of the proposed method is tested by applying
different geometric and image processing attacks, such as salt and pepper noise, Random noise, Rotation,
Additive Gaussian noise, Blurring and Motion Blurring attack. The proposed method, with stands for all these
attacks.
Future Scope:
The watermark embedding scheme can be extended to include encrypted watermarks. Watermark
extraction algorithm can be extracted to perform watermark validation automatically. Suitable feature extraction
& matching techniques have to be explored. In case of the progressive image transmission the schemes for
optimizing the data for each phase needs to be studied. The phase wise data compression & decompression
schemes need to be evaluated.
