隐域计算中的数据隐藏

Computing in Covert Domain Using Data Hiding

Zhenxing Qian, Zichi Wang, Xinpeng Zhang

摘要:

提出了隐域数据计算的思想。我们表明,信息隐藏的一些数据计算任务可以执行的封面下,如图像,音频,随机数据等,在建议的框架中,发送者隐藏他的源数据到两个封面,并将它们上传到服务器上。服务器在隐写中执行计算,并将隐写计算结果返回给接收方。利用该隐蔽结果,接收方可以提取源数据的计算结果。在这个过程中,由于源数据隐藏在封面中,服务器和对手都无法察觉。可以通过公共渠道进行传输。同时,由于计算是在隐蔽域中实现的,所以云不能获得计算结果的知识。因此,所提出的想法对于云计算是有用的。

英文摘要:

This paper proposes an idea of data computing in the covert domain (DCCD). We show that with information hiding some data computing tasks can be executed beneath the covers like images, audios, random data, etc. In the proposed framework, a sender hides his source data into two covers and uploads them onto a server. The server executes computation within the stego and returns the covert computing result to a receiver. With the covert result, the receiver can extract the computing result of the source data. During the process, it is imperceptible for the server and the adversaries to obtain the source data as they are hidden in the cover. The transmission can be done over public channels. Meanwhile, since the computation is realized in the covert domain, the cloud cannot obtain the knowledge of the computing result. Therefore, the proposed idea is useful for cloud computing.
