A Review on various approaches for image steganography

Abstract

Steganography is a technique for the secure transmission of data over the network. In this process, the secret information is transmitted by hiding this behind a signal or image or video. The Least Significant Bit embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file. This technique can be used for hiding images in 24-bit, 8-bit or gray scale format. In this process image is divided into different regions for the detection of least significant bits available in different images. Image pixel available in the image is a combination of three different colors red, green and blue.
