Chaotic Based Image Steganography Using Polygonal Method

Abstract

Information security is the most concerning factor in the time of tremendous innovative headway. Immense specialized information cleared a way for the development of information taking methods. Steganographic methods help to veil the mysterious data with some other media that goes about as a spread to the data. This strategy makes it hard for programmers to see the data since it shows up as a media instead of as data itself. Image steganography assists with concealing mystery data in any dimension and worth of images. These pictures can be traded without looking for any consideration of programmers to the mystery data inside it. Here the information is encoded into the image through an arbitrary rectangular region, to make it more secure. Using chaotic map we have generated random number series through which data embedded in rectangular region with uneven interval. This can be unscrambled at the beneficiary side with the best possible calculation alongside the secret key. We have scrambling the data and concealing it in the image utilizing the chaotic map. Removing the data and unscrambling it is done at the beneficiary. Embedding capacity of the proposed methodology is also comparable with other well known existing methodologies. Performance analysis is also measured and the proposed methodology generates enhanced result than the others.
