Natural language information hiding technology has been a research focus in the field of information security in recent years.Based on the analysis of the existing information hiding algorithms for natural language,we find that existing algorithms do not have enough hidden capacity and can not be applied to a variety of scenarios.In order to obtain a scheme with enough capacity and versatility,this paper presents a common abstract algorithm for natural language information hiding.With the concept of the cover unit as a link,the abstract algorithm divides the natural language information hiding algorithm into the cover control algorithm and hiding coding algorithm,and then realizes the abstraction of the existing algorithm.The abstract algorithm realizes the conjunctive use of a variety of cover control algorithms and effectively improves the hiding capacity.Because different embedded solutions can be flexibly applied to different scenarios,the versatility of the algorithm is achieved.Experimental results show that the abstract algorithm is versatile.
