Graph Coloring Based on Evolutionary Algorithms to Support Data Hiding Scheme on Medical Images

Medical record is a data that must be protected since only authorized person is allowed to access it. The problem is called confidentiality problem. Confidentiality problem can be solved without addition of files but by inserting the medical record into its corresponding medical image. In the previous research([1]), a medical record was inserted into the region of non interest of medical image using a scheme which is adopted from([2]). In this paper, we provide a performance comparison of the data hiding scheme based on graph coloring using two evolutionary algorithms, namely genetic algorithm and particle swarm optimization.
