Mohit Kumar, Akshat Agrawal, Ankit Garg . An Image Encryption Technique based on Concatenating Images of Same Dimensions. International Journal of Computer Applications. 98, 14 ( July 2014), 30-34. DOI=10.5120/17253-7595
Abstract
Images are widely used in many areas for various purposes. Some images may have confidential information, so security of secrete images is a major issue. Various image encryption algorithms provide security to images. However, traditional encryption techniques encode one image at a time, which leads to weak security in the encrypted image due to small size of the image. In this paper, an image encryption technique is imparted that concatenate four images of the same dimension into one and then produce single encrypted image. In result, encrypted image is more secure due to the large size. This encrypted image has high entropy and low correlation coefficient, so this encrypted image is more difficult to understand compared to four separated images.
