Zusammenfassung:By research on lossy compression technology about about the encrypt coding image, lossy predictive coding is analyzed, and optimal predictors altogether with optimal quantization was set up. Meanwhile, coding image model produces a fairly good effect by application on the encrypt image at the entrance of a network user on the platform of information network under WEB.
