A Technique for Image Encryption Based on Explosive n*n Block Displacement Followed by Inter-pixel Displacement of RGB Attribute of a Pixel

Image Encryption has gain popularity because of need of secure transmission of images over open networks and increased attacks on data flowing over network. Different type of data have different features, that is why for images different techniques were evolved to protect confidential data from unauthorized access. Encryption techniques used for encrypting textual data does not work with images, so separate encryption techniques are required for images. So, we proposed here a new scheme for image encryption which is helpful for end to end secure transmission of digital information on open network using explosive block displacement followed by inter-pixel displacement of RGB values.
