Abstract

Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. This paper intends to give an overview of image steganography, its uses and techniques. For a more secure approach, this paper encrypts the message using secret key and then sends it to the receiver. The receiver then decrypts the message to get the original one. The rapid development of data transfer through internet made it easier to send the data accurate and faster to the destination. This paper deals with the algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. This project gives a brief idea about the image steganographic approach that make use of Least Significant Bit(LSB) algorithm for embedding the data into the bitmap image(. bmp) which is implemented through the JDK 1. 5. 0_07 environment. The Least Significant Bit (LSB) 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.
