Abstract

In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealment. Recommendations for JPEG2000 encryption given in previous work have to be reassessed on the basis of our results. Improvements to the error concealment code of the JPEG2000 reference software JJ2000 are presented.
