摘要：This paper is proposed to provide confidentiality of the secret image which can be used by multiple users or to store on multiple servers. A secret sharing is a technique to protect the secret information which will be used by multiple users. The threshold secret sharing is more efficient as it is possible to reconstruct the secret with the threshold number of shares. Along with Shamir's secret sharing method we propose to use the radon transformation before dividing the image in to shares. This transformation is used so that the shares will not have the original pixel intensity. The run length code is used to compress the image after the transformation. Then apply secret sharing technique. The reconstruction of the image results in original image by applying the operations in the reverse order
