Data Hiding in Encrypted Images

Abstract—In the present method the data is hidden behind the images, the intruders can easily acquire this information because it is not encrypted. In this paper we have developed a technique to hide data in Encrypted images. We have explored the limits of Steganography theory and practise and have arrived to this unique method of data hiding. This paper intends to give an overview of image steganography and image encryption, its uses and techniques In the proposed system we are encrypting the data using the Rijndeal algorithm which is also used by the U. S. Military forces. This algorithm hides the data in the image using the LSB technique and the image is again encrypted using the RSA algorithm. For this entire encryption process the user has a password. After the encryption process is complete the sender sends the file to the receiver. The receiver can extract the data only if he is authenticated in the process of login
