利用鲁棒隐写系统提高信息安全

Improved information security using robust Steganography system

Mamta Juneja, Parvinder singh Sandhu

摘要:

隐写术是一个新兴的领域,它用于在任何公共媒体上进行安全的数据传输,隐写术是将信息隐藏在适当的载体(如图像或音频)中的过程。它起源于希腊语,意思是“隐藏或隐藏的文字”。载体可以被发送给接收者,除了被认证的接收者之外,没有任何人知道该信息的存在。在本文中,一个特定的图像为基础的隐写技术,更安全地在两个位置之间的信息通信。为了达到较高的安全性,作者将秘密密钥和口令安全特性的思想用于两端的认证。作为安全级别的进一步提高,对信息进行置乱、编码,最后嵌入到图像中形成隐写图像。此外,为了防止隐写图像在传输过程中的失真,在发送端和接收端分别采用归一化切割方法对隐写图像进行了分割对象提取和重组。

英文摘要:

Steganography is an emerging area which is used for secured data transmission over any public media.Steganography is a process that involves hiding a message in an appropriate carrier like image or audio. It is of Greek origin and means "covered or hidden writing". The carrier can be sent to a receiver without any one except the authenticated receiver knowing the existence of this information. In this paper, a specific image based steganography technique for communicating information more securely between two locations is proposed. The author incorporated the idea of secret key and password security features for authentication at both ends in order to achieve high level of security. As a further improvement of security level, the information has been permuted, encoded and then finally embedded on an image to form the stego image. In addition segmented objects extraction and reassembly of the stego image through normalized cut method has been carried out at the sender side and receiver side respectively in order to prevent distortion of the Stego image during transmission.
