WebApr 13, 2024 · An image encryption model is presented in this paper. The model uses two-dimensional Brownian Motion as a source of confusion and diffusion in image pixels. Shuffling of image pixels is done using Intertwining Logistic Map due to its desirable chaotic properties. The properties of Brownian motion helps to ensure key sensitivity. Finally, a … WebMar 1, 2024 · To validate these model predictions, the experimental data of the Brownian motion of colloidal beads on phospholipid bilayer by Wang et al. is used and compared with the results of the theory. This comparison suggests that the proposed model not only is able to explain qualitatively the Brownian yet non-Gaussian diffusion, but also quantitatively. go henry kids credit card reviews
