Particle Swarm Optimization based parameter optimization technique in medical information hiding

In this era of globalization, use of technology has influenced medical science as well. Now-a-days, exchanging medical information using communication technologies like network devices or telecommunication to provide health care services for medical case studies amongst various diagnostic centers or hospitals is a very common practice. In this paper, a Discrete Wavelet Transformation (DWT) based method is proposed for embedding a Hospital Logo or Electronic Patient Record (EPR), where the embedding factors/scaling factors are optimized by Particle Swarm Optimization (PSO).
