A New Data Hiding Method based on Lévy Flight Technique


Many data hiding methods and techniques were introduced in the literature, most of them by well recognized researchers that have undisputable impact on the scientific society, yet the focus was on using a general algorithm that apply the same parameters and guidelines each and every time on different data. Sometimes it yields good results in term of robustness of imperceptibility but many times it is a sacrifice of one to the favor of the other. Nature-inspired algorithms (NIAs) recently gained a significant amount of attention, regarding problem solving of complex problems in the field of optimization where an actual solution is hard to obtain due to vast number of parameters. In this paper an attempt is intended to enforce a certain NIA algorithm with goals of maximization of robustness, capacity and imperceptibility and minimization of distortion measured by some signal distortion detection parameters.
