In this paper we present a new method for a visual cryptography scheme that uses random basis column pixel expansion technique. This method encoded the secret image into `n' share images in a recursive manner, which have dimensions identical to the secret image. In this scheme, the encoded n shares further encoded into number of subshares recursively. It will increase the level of security of the encrypted message.
