Abstract :
Network-conscious image compression has been shown to provide faster progressive display than traditional compression algorithms, when images are transmitted over lossy low-bandwidth packet-switched networks. In this paper, we combine the advantages of wavelet-based, network-conscious image compression with a blind digital image signature technique. Together these two approaches investigate progressive display where each progressive image can be authenticated by the receiver in real time
