Joint source channel and security arithmetic coding/decoding techniques for EBCOT in JPEG2000

Abstract

In order to improve the error resistance and security of JPEG2000 standard, a joint source channel and security arithmetic coding/decoding scheme for EBCOT in JPEG2000 is proposed. Based on error resistant arithmetic coding, this scheme inserts multiple forbidden symbols and generates secure two-way decodable bitstream controlled by chaotic maps, improving the security of the scheme. Meanwhile, at the decoder, the scheme combines soft and hard decoding together with threshold control and two-way decoding is adopted to improve the error-correcting capability. Simulation results show that the proposed scheme can achieve lower decoding complexity, better error resistance and security.
