With wide spread of image and video in internet, various kinds of novel implementations have ap-peared in recent years .In some of these implement ations,private-inform at ion-contain images are employed usually .Due to vulnerability to illegal accessing during transmission of image and video,requirement of secu-rity is impending .A new algorithm is addressed and the essence of this method is that by combination of Dis-crete Wavelet Transform(DWT), Embedded Zerotree Wavelet Algorithm(EZW),and Advanced Encry p-tion Standard(AES), encrypt compressed stream to ensure the transmission efficiency and security .The ex-periments demonstrate that our new algorithm can improve the security of media stream besides keeping hig hcompression rate.
Key words： image encryption; image compression; DWT; EZW; AES
