Fibonacci Based Text Hiding Using Image Cryptography

Abstract

In digital word security is a most important issue and data hiding with image cryptography is one of the possible ways to ensure the security of the important message from outer world. In this paper we proposed a novel technique that encrypted the message such a ways that the message encoded as well as hidden in an image. The proposed solution is to use image cryptography to hide textual message. The proposed technique use of an encryption technique that is based on Fibonacci series & image encryption and a secret key generated from the image. 

A New Encryption Algorithm Based on Fibonacci Polynomials and Matrices

“…According to a novel method put forth by Mukherjee and Samanta [1], a message can be both encoded and hidden in an image by using the Fibonacci series to encrypt it.…”

“…Thereby, a change column matrix is obtained, and then divided into blocks to be multiplied by the 2×2 Fibonacci polynomial matrix (1). The generated new 2×2 type matrices adopt mode 2 and irreducible polynomials x 4 +x+1, respectively.…”

“…Polynomials play a significant role in mathematics and are widely employed, particularly in the field of cryptology. One of these is the Fibonacci polynomial, which has been employed in a number of research that have been published in the field of cryptology [1][2][3][4][5][6][7][8]. In this paper, the literature review summarizes these investigations.…”
