A block cipher in CBC mode is used to encrypt the bitstream of each J2K code-block. The encrypted J2K codestream preserves almost the same fine granularity scalability as the original J2K codestream yet with small or negligible overhead, and has fine and near RD-optimal truncations for a large range of bitrates. The proposed scheme enables desired transcoding directly on a single encrypted codestream without decryption to fit diverse capabilities of devices and heterogeneous networks with time-varying bandwidths. Any node, trusted or not, along the delivery path is able to perform desired transcoding without sacrificing the end-to-end security of the system.}, publisher = {IEEE}, url = {http://approjects.co.za/?big=en-us/research/publication/jpeg-2000-encryption-enabling-fine-granularity-scalability-without-decryption/}, edition = {IEEE Int.
