An efficient hybrid encryption approach with bit shuffling for image data security

In the current scenario there is the need of data security to make the communication more secure and reliable. In this paper image data security has been discussed. The major problem is to provide security in less time with minimum loss of data. In this paper a combination of RSA, RC4 and blowfish (R2B) algorithms have been used for the data encryption and decryption purpose. For experimentation different images have been considered from different databases. The experimentation has been considered based on mean squared error (MSE), encryption time and overall processing time. The results have been considered based on different iterations to reduce any computational biasness. The results clearly show the improvement in error rates, encryption time and overall processing time as comparison to the traditional approaches.
