In this paper apprized three paradigms for visual cryptography for TAMIL Characters, wherein k out of n shares is sufficient to see the confidential information. Visual and polynomial-based are the two major categories in cryptography. This paper incorporates both simple and composite models to accomplish secret sharing. Secret data is sent to the holders as shares but how they decrypt the shares to retrieve the secret is a closed book. Procedures involved in sectoring the secret as shares need to be very intricate enough to attack. Advantages of visual cryptography are no requirement of cover image, unable to recovery with partial shares, litheness, and ease of sending each share in different media and so on. This paper suggests three such methods wherein the shares submit themselves to unequaled manipulative processes and then sent to the holders. For readers all the inputs, their shares and the decrypted output are depicted for better understanding without decryption.
