In this paper we propose a progressive encryption and controlled access scheme for JPEG 2000 encoded images. Our scheme applies SNOW 2 stream cipher to JPEG 2000 codestreams in a way that preserves most of the inherent flexibility of JPEG 2000 encoded images and enables untrusted intermediate network transcoders to downstream an encrypted JPEG 2000 image without access to decryption keys. Our scheme can also control access to various image resolutions or quality layers, by granting users different levels of access, using different decryption keys. Our scheme preservers most of the inherent flexibility, scalability, and transcodability of encrypted JPEG 2000 images and also preserves end-to-end security.
