Abstract
Confidentiality of secret information is one of the mandatory issue of digitally modernized era of science and technology. Due to availability of several online web applications and social media usages nowadays, information is transmitted with ease. The privacy of these digital information can be addressed by using different encryption mechanisms. We have proposed digital information privacy preserving scheme based on three-dimensional chaotic self-exciting single disk homopolar system. Moreover, we have designed a circuit implementations of three-dimensional chaotic self-exciting single disk homopolar dynamical system. The suggested encryption scheme is tested against different security performance analyses which clearly reflects the affectedness of our encryption scheme.
