6.3. Lossless Information Hiding in JPEG2000 Images
As an important branch of information security, information hiding in images has been extensively studied in recent years. However, most schemes will introduce irreversible distortion to the original image. It is unallowable in some special applications such as legal imaging and medical imaging. So reversible information hiding deserves us to study. In addition, most existing information hiding schemes are for BMP and JPEG images. There are few related schemes for JPEG2000 images. So it is very necessary for us to study reversible information hiding for JPEG2000 images.
6.3.1. Overview
To understand the following schemes better, we introduce the JPEG2000 codec first. The block diagram of the JPEG2000 ...
