讨论了广义信息隐藏技术的分类,提出了按照实物、物理、化学、数学、语言等学科体系的分类方法,据此系统地讨论了信息隐藏技术的基本特征,重点讨论了自然语言和人工语言信息隐藏技术,研究了这两类基于词法、语法、段落和语义的信息隐藏技术的基本特征,并纠正了目前关于基于语义信息隐藏概念的一个误解,进一步得出了基于语言学的广义信息隐藏技术分类模型。 The classification of generalized information hiding technology is discussed. The classification method based on the subject, physics, chemistry, mathematics, language and other disciplines is proposed. The basic characteristics of information hiding technology are discussed systematically, with emphasis on the discussion of natural language and artificial language information Hides the technology, studies the basic characteristics of these two types of information hiding techniques based on lexical, grammatical, paragraph and semantic, and corrects a misunderstanding of the current concept of hiding based on semantic information and further obtains a generalized information hiding technique based on linguistics Classification model.
