Abstract
In this report, we discuss error resilient encryption of JPEG2000 images for transmission channels with bit errors. The simplest method for encrypting JPEG2000 images is to apply block encryption algorithm to image data with regarding them pure bit-stream. With this method, however, a bit error frequently cause large deterioration of an reconstructed image because the method disregard error resilient functions of JPEG2000. Therefore, we propose a encryption method for obtaining better error resilience by considering data organization of JPEG2000 and exploit its error resilience functions. To confirm the effectiveness of the proposed method, we have some simulations.
