基于数字分解的数据隐藏技术

Data Hiding Techniques using number decompositions

Rajdeep Borgohain

摘要:

数据隐藏是一种将数据嵌入数字媒体的艺术,其方式是使数据的存在对除预期接收者之外的所有人保持隐藏。在本文中,我们讨论了各种最低有效位(LSB)的数据隐藏技术。我们首先研究了经典的LSB数据隐藏技术和通过位操作将秘密数据嵌入到覆盖媒体中的方法。我们也看一看的数据隐藏技术位平面分解的基础上Fibonacci数。该方法生成更多的位平面,允许用户将更多的数据嵌入到封面图像中,而不会导致显著的失真。本文还讨论了基于素数和自然数位平面分解的数据隐藏技术。这些方法是基于映射的图像位大小序列的分解位数隐藏的信息。最后,我们提出了这些数据隐藏技术的比较分析。

英文摘要:

Data hiding is the art of embedding data into digital media in a way such that the existence of data remains concealed from everyone except the intended recipient. In this paper, we discuss the various Least Significant Bit (LSB) data hiding techniques. We first look at the classical LSB data hiding technique and the method to embed secret data into cover media by bit manipulation. We also take a look at the data hiding technique by bit plane decomposition based on Fibonacci numbers. This method generates more bit planes which allows users to embed more data into the cover image without causing significant distortion. We also discuss the data hiding technique based on bit plane decomposition by prime numbers and natural numbers. These methods are based on mapping the sequence of image bit size to the decomposed bit number to hide the intended information. Finally we present a comparative analysis of these data hiding techniques.
