摘要：Visual cryptography scheme is one of the most secure techniques for privacy protection, that allow the encryption of secret image or data by transferring it into the secure share and such a scheme is able to recover the secret image or data without any computation devices. In today’s era security of that transmitted data is most important problem because network technology is greatly advanced and lot’s of information is transmitted via the internet. Visual cryptography scheme allow encoding the original message to hide its meaning and decode it to reveal the original message. Also encoding of information in the number of shares and distributed to number of participants, which decrypt information without any cryptographic knowledge. The shares are sent through different communication channels from sender to receiver so that the probability of getting sufficient shares by the intruder minimized. But the shares may arise suspicion to the hacker’s mind that passed information is secret. We can encrypt original image using a key to provide more security to this scheme. This makes visual cryptography scheme a completely secure scheme
