Abstract
This Paper discusses how a text file is to be kept secret while transmitting from sender to receiver. This paper is intended to present the techniques for encryption and Steganography. Steganography is the practice of concealing messages or information in host data or text or an image. There are many different carrier file formats, but digital images are the most popular as their frequency of occurrence is more on the internet. Steganography is an improved method of securing message than cryptography that solely conceals the content of the message not the existence of the message. Steganography is a tool which allows furtive transmission of information over the communication channel. Combining the secret message with the carrier image provides the Stego image. In this paper, double coding algorithms are accustomed hide the encrypted text in a host image that makes the secret message is difficult to detect without retrieval. This paper presents a technique which could transmit with high security.
