Text to Image Encryption Using 16*16 Playfair Cipher and Dynamic Color Channel Selection Technique

摘要

There are many encryption techniques. But almost all of these Encryption techniques work as a combination of substitution and transposition. They are usually text to text as this saves memory. We propose a method of encryption for environments where memory is not an issue but security is. In this paper we cover how one can do a basic playfair cipher and then encapsulate the cipher text hence into an RGB image. Where R, G, B, each are channels. These channels will be where the cipher text will be put in to create an image. Hence encapsulating the data.
