Abstract

This paper proposes a novel data hiding method for JPEG 2000 coded images that embed multi-level information into quantized discrete wavelet transformed coefficients. Since the proposed method hides information represented as an integer to a transformed coefficient rounded to an integer, a JPEG 2000 code-stream conveying data keeps its standard JPEG 2000 code-stream structure. The proposed method is able to extract hidden data without memorizing embedding positions; it thus chooses transformed coefficients to which data is hidden freely. This characteristic makes the proposed method suitable for hiding data to a JPEG 2000 coded image with consideration of Region of Interest (ROI) coding that is a major feature. Simulation results show the effectiveness of the proposed method. © 2007 Wiley Periodicals, Inc.

一种基于模运算的JPEG 2000编码图像数据隐藏方法

本文提出了一种新的JPEG 2000编码图像数据隐藏方法，该方法将多级信息嵌入量化的离散小波变换系数中。由于所提出的方法将表示为整数的信息隐藏为四舍五入到整数的变换系数，因此传送数据的JPEG 2000码流保持其标准JPEG 2000码流结构。所提出的方法能够在不记忆嵌入位置的情况下提取隐藏数据；因此它选择数据被自由隐藏的变换系数。该特性使得所提出的方法适合于在考虑作为主要特征的感兴趣区域（ROI）编码的情况下将数据隐藏到JPEG 2000编码的图像。仿真结果表明了该方法的有效性。©2007 Wiley Periodicals，股份有限公司Electron Comm Jpn Pt 3，90（7）：37–462007；在线发表于Wiley InterScience（www.InterScience.Wiley.com）。DOI 10.1002/ecjc.20286
