Embedding Multilevel Image Encryption in the LAR Codec

Abstract

A still image codec should not only to be good from compression point of view, it might also provide services. The LAR interleaved S+P codec allows lossless to lossy coding, presenting both resolution and distortion scalability. The proposed method brings image encryption at no cost in the LAR framework. It exploits the embedded quadtree decomposition of the LAR to provide multilevel protection to the whole bit-stream. Theoretical aspects are considered and experimental results show the effectiveness of the process.
