According to the security of the scalable video stream

an integrated video compression-encryption scheme was proposed.The scheme chooses wavelet transform as the compression platform

encrypts the zero-tree symbol during the zero-tree generation process to guarantee the security of the video.Furthermore

a multiple levels encryption was proposed to satisfy different consumers’ requirement.It is proved that the scheme kept the scalability of the encoding

has high security

and small impact on compression efficiency

so it is suitable for real-time video transferring on the network.
