Most of the recently proposed steganographic schemes are based on minimizing an additive
distortion function defined as the sum of embedding costs for individual pixels. In such an …

Steganography is the art and science of hiding a message in a carrier, in such a manner that
no one, except the sender and intended recipient, can guess the existence of the message; …

A secure method for steganography is proposed. Pixel-value differencing (PVD)
steganography and bit-plane complexity segmentation (BPCS) steganography have the …

Blind image steganalysis is exploring body of digital images for the likely presence of hidden
secret messages without knowledge of the employed steganographic technique. This paper …

Calibration based attack is one of the most important steganalytic attacks in recent past
specifically for JPEG domain steganography. In calibration attack, the attacker generally …

The traditional way to represent digital images for feature based steganalysis is to compute
a noise residual from the image using a pixel predictor and then form the feature as a …

A novel adaptive steganographic scheme for spatial image is proposed. A noisy function is
used to measure texture complexity of 2× 2 pixel blocks, which keeps monotonic increasing …

Image steganography is a technique of masking secret information (eg text, image, audio,
video etc.) in a cover image in order to protect the information from being modified or …

A well defined cost function is crucial to steganography under the scenario of minimizing
embedding distortion. In this paper, we present a new cost function for spatial image …

With the coming era of cloud technology, cloud storage is an emerging technology to store
massive digital images, which provides steganography a new fashion to embed secret …
