【摘要】 近年来,信息隐藏作为一门新兴学科得到了迅速的发展。但人们对信息隐藏的本质仍缺乏深刻的认识。以分析现有的信息隐藏性能评价方法为基础,将信息隐藏与物理学进行类比,提出信息隐藏的"层次性"概念,并从层次性角度探讨了信息隐藏的安全性。更多还原

【Abstract】 As a latest subject, Information Hiding has received a rapid development in recent years. But the essence of Information Hiding is still obscure. In this paper, we make an analysis of different methods for evaluating the performance of Information Hiding. Then, after finding the analogy between physics and Information Hiding, we introduce the concept level property of Information Hiding and discuss the security of Information Hiding in terms of level property.更多还原
