چکیده

Data hiding is an age-old technique used to conceal an image, text of vital importance inside an image or video sequence. Several attacks are prevalent in an attempt to hack the data hidden inside the image. Several algorithms have been put forward focused in making the embedding technique to be robust to such attacks. The current work is focused towards studying the behavior of Spatial and Frequency Domain Multiple data embedding techniques towards noise prone channels and Geometric attacks enabling the user to select an optimal embedding technique. The robustness of the watermark is tested by introducing several attacks and testing the watermark strength.

Attenuation of spatial aliasing in CMP domain by non-linear interpolation of seismic data along local slopes

Spatial aliasing is an unwanted side effect that produces artifacts during seismic data processing, imaging and interpolation. It is often caused by insufficient spatial sampling of seismic data and often happens in CMP (Common Mid-Point) gather. To tackle this artifact, several techniques have been developed in time-space domain as well as frequency domain such as frequency-wavenumber, frequen...

Using Invariant Image Features for Synchronization in Spread Spectrum Image Watermarking

Awatermarking scheme is presented in which the characteristics of both spatial and frequency techniques are combined to achieve robustness against image processing and geometric transformations. The proposed approach consists of three basic steps: estimation of the just noticeable image distortion, watermark embedding by adaptive spreading of the watermark signal in the frequency domain, and ex...

Appraise Of Multifarious Image Steganography Techniques

This paper presents a review of multifarious methods available for image steganography. The steganography is an art and science of invisible communication. The image steganography is divided into four basic terminologies viz. cover image, message, stego image, embedding and extracting algorithm. In this paper comparison of steganography with other security techniques is done. Image steganograph...

Eigenvalues-based LSB steganalysis

So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...
