Abstract: Visual cryptography in modern days is of paramount way of secured way of communicating the secret image. In this study, a novel algorithm Differential Particle Swarm Visual Cryptography (DPSVC) is proposed for generating the secret key. In this approach the particle swarm optimization is hybridized with differential evolution algorithm. Modification of every particles velocity in the swarm by applying the mutation using differential evolution algorithm. Dynamic key generated for visual cryptography of the color shares are based on the solution space using the histogram frequency of the image to be encrypted. This novel algorithm has improved the performance of the visual cryptography by 93.5%.
