英文摘要： The existing text steganography method is facing huge security threats and challenges, and thus there is an urgent need to find new effective method to solve these problems. As the main carriers of information dissemination in modern society, network text has many beneficial features and advantages for information hiding. So, research on network text steganography has important theoretical and practical significance. This project innovatively uses the many features of network text to study a novel information hiding method based on semantemes of network text. The main research contents of this project include: (1) We'll try to study the construction and organization strategy, mechanism and approach of the thesaurus for the use of information hiding based on the semantemes of texts, so as to establish the thesaurus for the use of efficient information hiding; (2) In order to improve the secrecy, robustness and capacity of text information hiding, we'll firstly try to study the effective synonym replace mechanism and algorithm for network text, and then to explore the new information hiding method based on the characteristics of network text; (3) To explore an effective evaluation model and method for semantic information hiding of network text, and then the improvement and perfection of the method proposed in this project will be put forward; (4) We'll finally do experimental study, so as to lay the foundation of the practical application of the research results generated by the proposed project. Our project will find out a novel and effective way for information hiding based on network text. The proposed project will also provide theoretical support for secret communication and copyright protection of network text production based on the semantic of network text, and thus enhance the research and application level of our country in related fields. The work done in this project will also enrich and develop the theory and technology system of information hiding area.
