A New Image Sharing Scheme for Internet Applications in Adverse Environments

Based on poly-phase sampling and lookup table encryption techniques, a new image sharing scheme is presented with several aspects of innovations in this paper. Each shadow can be independently decrypted to obtain part of the original image, any pair of decrypted sub-images has very high correlation, it still obtains acceptable image quality when channel congestion occurs, and quality refinement of the recovered image is proportional to number of shadows obtained and achieves perfectly with all shadows. As a result, our method is highly suitable for Internet applications in adverse environments with real-time progressive reconstruction. Experimental results demonstrate the promising characteristics of our method.
