Comparative Analysis of Canny Edge based Image Steganography with RSA Encryption
Sanjay Yadav, A. K. Thripati · International Journal of Advanced Science and Technology · 2017
In this survey, we give a brief overview on image steganography, which is based on Edge detection with RSA and Least Significant Bit (LSB) methods.There are two main problems, viz.Steganography and Cryptography.In the Cryptography process, it changes the arrangement of the text itself, whereas in Steganography covers the text behindhand some other digitally illustrative media, thus communicating it unintentionally.But with the enlarge in networks practice and advancements in expertise, it has developed progressively more difficult to defend the facts.The proposed method takes different types of color (RGB) image as a carrier to hide text data.The encrypting text with the support of a key which makes the location of unique content difficult still if some impostor succeeds in obtaining the hidden data.The canny detection method is used to hide encrypted message and the hash function is used to embed text message or data in the image.The proposed method is going to be implemented using MATLAB and its strength will be matched through computing the mean square error and the peak signal noise ratio.Probably the proposed method may have better security against Steganalysis attacks.
