An enhanced security measure for multimedia images using hadoop cluster

Abstract

Information is generated over the internet every second. This information is not fully secured. To increase the security of this information, there are two methods. Cryptography and steganography are combined to encrypt the data using RSA algorithm as well as to hide the data in multimedia image in Hadoop cluster. Features of the resultant image such as color are extracted and stored separately in Hadoop cluster to enhance security. The features of the stenographic image for secret image retrieval, which has been split into image and secret information, are combined. At last, decrypting the secret information, the authors retrieve the actual information. Application of this system in Hadoop will increase the speed of execution of the process.
