A new image scrambling approach using block-based on shifted algorithm

Image scrambling is a useful approach to secure the image data by scrambling the image into an unintelligible format. This paper proposes a new scramble algorithm which can be produced by a series of shifting the rows and the columns. The first part of the algorithm aims to build a shifted table usi...
