JPEG2000 is an emerging international standard for still image compression and is becoming the solution of choice for many digital imaging fields and applications. Part 8 of the standard, named JPSEC, is concerned with all the security aspects of JPEG2000 image code-streams, with emphasis presently on access control and authentication. An important aspect of JPEG2000 is its “compress once, decompress many ways”...
An important aspect of JPEG2000 is its “compress once, decompress many ways” property [1], i.e., it allows users with different preferences, privileges or capabilities to extract various sub-images all from a single compressed image code-stream.
