In highly digitalized word, internet plays a very important role in communication. If the data in
communication is confidential, then information security becomes an essential issue …

In this paper, the authors have proposed an image steganography method for improving the
embedding capacity of the gray-scale cover image. In general, the embedding of the secret …

Steganography is a technique of hiding secret data into digital images in different domain
like frequency, spatial or wavelet. Data hiding in image change its statistical properties …

Steganography is an important area of research in recent years involving a number of
applications. It is the science of embedding information into the cover image viz., text, video …

Image steganography is the art of hiding information into a cover image. It derives from the
