We propose a novel multimedia security framework based on the nonlinear properties of the arithmetic coder, which is used by most image and video coding standards in the entropy coding stage. This technique performs simultaneous entropy coding and encryption which reduces the delay and the required system resources by manipulating the probability maps of the arithmetic coder. Furthermore, the proposed technique does not incur any additional complexity for performing encryption, nor does it increase the size of the compressed image. Consequently, when applying the proposed technique to un-encrypted images, in contrast to standard encryption techniques, the decoder can still progressively display the decoded/deciphered image. Furthermore, there is no companion error-propagation usually associated with this type of encryption. The proposed scheme does not need to append any extra bits to the coded bit stream, unlike most block ciphers. The proposed technique can be applied to any multimedia coder using arithmetic coding. However, the implementation in this paper is tailored to the JPEG2000 standard. Also, we introduce assessments and measurements for this encryption technique. |
