Secret Image Protection using Image Fusion

Images are considered for handling in different fields. The paper has an algorithmto guardthe key image whose privacymust be kept up and verify the dealer who needs to disseminate that key image to a numerous clients. For authentication purpose the key image and palm-print of dealer are fused. In this paper Dual Tree Discrete Wavelet Transform is applied on both key image and palm print, coefficients obtained from both images are being fused using Image Fusion technique. DTDWT is used to overcome the drawbacks of DWT. Image fusion is a strategy or a procedure of consolidating pertinent data from set of pictures into a solitary picture, the resultant picture got will be more finished and useful than the information pictures. The threshold secret sharing is used to distribute the fused image to many shares. This gives both privacy as well as verification about the dealer whoever sends the image. During decryption key image is known and the palm print of the dealer has to be reconstructed from the shares collected from authorized users, finally verification is done.
