Data hiding in JPEG 2000 code streams

Abstract

In this research, the issue of integrated data hiding and JPEG 2000 [Mar 2000, Dec 2000] image compression is investigated and a data-hiding scheme is proposed to embed covert messages into JPEG 2000 code streams. With the introduction of visual masking measurement and CSF weighting, visual distortion is very slight even though a large amount of data is embedded. The extraction of hidden data can be performed progressively at the decoder. Experimental results are given finally to show the performance of the proposed scheme.
