| 摘 要： | 信息传送的安全性已成为许多领域所关注的热点和难点,如何在大量的数据载体中嵌入有用的重要信息并将其安全的发送出去是一个值得研究的重要课题。应用DCT和DWT两种变换方式对信息进行二次隐藏,根据相关理论提出隐藏的算法和实现的可能过程,并对实现中可能存在的不足和改进进行了简要分析。结果表明二次隐藏作为一种深度隐藏方式理论上可以实现,在实践技术方面还需进一步完善。二次隐藏技术的发展将在网络安全方面有独特的应用前景。

| Abstract: | Nowdays, the safety of the information transfer has become a hot - debated and important topic. How to transfer a large number of important information and make them more safe is a very valuable job. This paper proposes to use DCT,DWT to hide the information twice ,and provides the hidden method and the possible processes based on the correlative theory . Furthermore, this paper simply analyzes the possible shortages and provides a creative improving idea. As a result, twice hidden technology can be realized although it needs much improvement . Lastly , with the twice hidden technology development, it can be used particularly in the net safety field. |
