    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%.}
