In this paper, the authors propose a new visual cryptography algorithm for secret data communication over internet. This method combines the advantage of normal encryption and visual cryptography. The secret image is converted to multiple share images using a new visual cryptography algorithm. These shares are same as the cover images used thus the share management problem is reduced. At the receiver side these shares are overlapped to form the secret image back. This method can be used for secret sharing among multiple people by generating multiple shares from single secret image. This method provides perfect reconstruction of secret image.
