Abstract

由於網際網?及電腦技術的快速發展,使的?位資?的複製與傳送變得簡單而快速;但是卻衍生機密資?容?遭到非法者竊取及竄改等問題。如何確保資?傳輸時的安全性,成為非常重要的議題。而?用資訊隱藏技術?提供機密資?的保護,成為近??熱門的研究主題。 一個?好的資訊隱藏技術可由幾個方面?評估:即強韌性、?可?性、容?及安全性等。然而這些特性幾乎?是互相衝突的,?如?提高隱藏資?的容?,即會?低資?的隱蔽性及強韌性。因此,發展可以同時滿足上述各項要求的隱藏技術,是目前研究者的最大挑戰。 本?文將針對近??已發表的資訊隱藏文獻,進?重點式的整?與探討,以提供從事此研究之專家學者於設計資訊隱藏演算法之?考。
Due to rapid development of the Internet and computer techniques, duplication and distribution of digital information has become easier and quicker than before. How to protect the security of secret information has become an important researching issue. In recent years, information hiding has become an attractive topic in protecting the secret information and has widely discussed in multidisciplinary fields. A good technique of information hiding can be estimated by several aspects, including robustness, imperceptibility, capacity, and security. However, these characteristics are mutual conflicting. For example, increasing embedding capacity will degrade the imperceptibility and robustness. Hence, developing a technique that meets above requirements at the same time is a challenge for many researchers. . The paper will discuss some information hiding techniques that have published to provide some new directions for designing algorithm of information hiding.
