Security, the most common word uttered by any man, any device, any peripheral since past two centuries. Protection from malicious sources has become a part of the invention or the discovery cycle. Myriad methods of protection are used ranging from a simple authentication password to most cryptography algorithms for protecting the extreme sensitive or confidential data. This paper proposes three indigenous methods as a variant of Cipher Block Chaining (CBC) mode for image encryption by considering three different traversing path (Horizontal, Vertical and Diagonal). In method one simple Raster Scan has been employed to scramble the confidential Image called Horizontal Image Scrambling (HIS). Method two is a variant of method one called Vertical Image Scrambling (VIS), here traversing path would be top to bottom left to Right. Third method employs diagonal traversing path called Diagonal Image Scrambling (DIS). Later Image Steganography has been adapted to send these Scrambled Images in an unnoticeable manner. Simulation has been performed to test the effectiveness & complexity of the proposed methodology.
