In this paper we present a secure and robust content based digital signature scheme for verifying the authenticity of JPEG2000 images quantitatively, in terms of a unique concept named Lowest Authenticable Bit-Rates (LABR). Given a LABR, the authenticity of the watermarked JPEG2000 image will be protected as long as its final transcoded bit-rate is not less than the LABR. The whole scheme, which is extended from the crypto data-based digital signature scheme, mainly comprises signature generation / verification, Error Correction Coding (ECC) and watermark embedding / extracting. The invariant features, which are generated from fractionalized bit-planes during the procedure of EBCOT (Embedded Block Coding with Optimized Truncation) in JPEG2000, are coded and signed by the sender's private key to generate one crypto signature (hundreds of bits only) per image, regardless of the image size. Error Correction Coding (ECC) is employed to tame the perturbations of extracted features caused by processes such as transcoding. Watermarking only serves to store the check information of ECC. The proposed solution can be efficiently incorporated into the JPEG2000 codec (Part 1) and is also compatible with Public Key Infrastructure (PKI). After detailing the proposed solution, system performance on security as well as robustness will be evaluated
