INFORMATION SECURITY MECHANISM BY GENERATING STRONG PASSWORDS THROUGH IMAGE FUSION amp; MULTISHARE KEY CRYPTOGRAPHY TECHNIQUE

摘要

Present invention provides specially an enhanced information security mechanism by generating strong passwords through image fusion and multi-share key cryptography technique.In this we proposed strong passwords using Image Fusion and Visual Cryptography mechanism as an alternative to alphanumeric passwords. This is because humans tend to remember visuals better than text.Image fusion is a process which combines the pixels or data from two or more source images from the same scene to Generate one single image containing more precise details of the scene than any of the source images. In addition to this, we are adding resultant images with audio file to generate strong password precisely pick and random shares from this resultant image & generate strong password mechanism hence experimental results are qualitatively evaluated by calculation of root mean square error, entropy; mutual information, standard deviation and peak signal to noise ratio measures.Following invention is described in detail with the help of Figure 1 of sheet 1 showing block diagram of strong password mechanismand Figure 2 of sheet 2 showing the proposed password generator algorithm.
