Secured Data Transmission using 2LSB Steganography

Abstract

Steganography contains transmitting secret messages through seemingly innocuous files. Steganography means hiding information by embedding secret data into an innocuous medium. In this study message bits are embedded randomly to achieve the higher security by combining cryptography and steganography. The contents of a message protect in Cryptography and Steganography is used to protect both messages and communicating parties. 2LSB technique is used to improve data capacity in an image. Selected components of pixel are used for embedding. In this study, we find a method to hide a secret message randomly in the image and how the parity of data can be used effectively.
