We proposed a fast secret image sharing based on Haar wavelet transform and Shamir's method. Many researchers develop secret image sharing method with Shamir's algorithm in one whole image. We employ discrete Haar wavelet transform to reduce the secret image to its quarter size firstly, i.e. the 1-level LL subband. Then only apply the modified Shamir's algorithm to this LL subband to generate the shadow images. Lagrange method exploits the enough numbers of the shadow images in the retrieval… CONTINUE READING
