Srinivas Koppu, V. Madhu Viswanatham · International journal of intelligent engineering and systems · 2016
In this paper, we have proposed a chaos-based visual encryption method that can be applied to Ultra Sound Medical Images.We used adaptive Grey Wolf Optimization (GWO) to archive Ultra Sound Medical Image encryption.The robustness of the proposed image encryption are measured by various security attacks such as key sensitivity, histogram analysis, adjacent pixel autocorrelation, chi-square test, etc.Moreover, analytical outcomes are compared with the conventional algorithms like Genetic Algorithm (GA) and GWO.The experimental result shows that the proposed method is faster with low complexity.
