Mobile multimedia applications, the focus of many forth-coming wireless services, increasingly demand low-power techniques implementing content protection and customer privacy. In this paper a low-complexity, perception-based partial encryption scheme for telephone-bandwidth speech is presented. Speech compressed by a widely-used speech coding algorithm, ITU-T G.729 CS-ACELP at 8 kb/s, is partitioned in two classes, one, the most perceptually relevant, to be encrypted, the other, to be left… CONTINUE READING
