In this article, we propose a novel integrated approach to quantitative semi-fragile authentication of JPEG2000 images under a generic framework which combines ECC and PKI infrastructures [1] [2] . Firstly acceptable manipulations (e.g., re-encoding) which should pass authentication are defined based on considerations of some target applications. We propose a unique concept of lowest authenticable bit rate -images undergoing repetitive reencoding are guarantee to pass authentication provided

Our solutions include computation of content-based features derived from the EBCOT encoding procedure of JPEG2000, error correction coding of the derived features, PKI cryptographic signing, and finally robust embedding of the feature codes into image as watermarks.
