The fundamental objectives of image steganographic algorithm are to simultaneously
achieve high payload, good visual imperceptibility, and security. This paper proposes a new …

Visual attention is a crucial indicator of the relative importance of objects in visual scenes to
human viewers. In this paper, we propose an algorithm to extract objects which attract visual …

Steganography surpasses other mechanisms of securing data from potential threats. The
modern digital arena calls for robust information hiding techniques and, thus, it has always …

The Internet and cloud services are widely used in transmission of large amounts of data
over open networks and insecure channels, exposing private and secret data to serious …

This paper focuses on steganography based on pixel intensity value decomposition. A
number of existing schemes such as binary, Fibonacci, Prime, Natural, Lucas, and Catalan …

In this paper, an effective self-embedding fragile watermarking scheme is presented. The
watermark is generated by encoding the DCT coefficients of each 2× 2 block and embedded …

In this paper a DWT based frequency domain steganographic technique, termed as WTSIC
has been proposed where the cover PPM image transform into the time domain through …

This paper deals with a novel steganographic technique which demonstrates the colour
image authentication technique in frequency domain based on the Discrete Fourier …

Image steganography is the art of hiding information onto the cover image. In this paper a
Genetic Algorithm based color image authentication/data hiding technique through …

In this paper a G-Let based authentication technique has been proposed to authenticate
digital documents through Hough transform generated signature generated from original …
