An approach of cryptography and steganography using rotor cipher for secure transmission

Abstract

This paper manifests an innovative approach to transfer sensitive data in an interrupted communication channel using the dyad protection techniques of Cryptography and Steganography. Applying Rotor Caesar cipher on the message followed by 2 bit LSB Steganography helps to conceal the information from the intruder. This Steganography strategy is achieved by using Python Image library along with OpenCV framework.
