摘要

本文在讨论基于融合的数字图像隐藏技术算法的基础上

提出了一种基于融合的数据隐藏算法.该算法利用一次Bézier曲线

将秘密数据隐藏在原始图像中.该算法可以在数字图像中嵌入任意形式的数字化数据

在选取适当的参数时

可以完全正确地恢复出数字化数据.该算法的特点是数据隐藏能力强

在以灰度图像为原始图像的情况下

其最大隐藏能力可以达到3bits/pixel.

Abstract

A novel approach to embedding digital data into a cover image using simple Bézier curve is proposed on the base of harmonic amalgamation algorithm whose purpose is to hide digital images.A message embedded by this approach can be in the form of text

imagery

or any other digital signal.The data to be embedded is treated as a binary stream and is partitioned into a number of sub-streams.Each sub-stream of data is converted into values that are then embedded into the public original image.Given appropriate parameters

it could be proved that digital data embedded by this approach could all be recovered correctly by data recovering process with the knowledge of original image.The advantage of this approach is high efficiency of data hiding.Its maximal efficiency of data hiding could come up to 3 bits/pixel when using gray images as public original images.Experimental results show that the proposed approach is feasible.
