A Text Information Hiding Algorithm of Song Poetry Carrier Based on Sentence Pattern Control
摘要
Abstract
In this paper, a text information hiding scheme of Song poetry carrier based on sentence pattern control is proposed for the problem that current text information hiding algorithm is featured with low embedding rate, weak stealthiness and easy to be tested by machine.Through analyzing the relationship between rhythm and word class in template of Song poetry versification, word-class extraction algorithm of Song poetry dictionary was designed, capacity of "rhythm-word class" dictionary generated after processing exceeded 40000 words, with 4 word classes and 32 rhythms.Information hiding and extraction algorithm under the control of the designed sentence pattern could covert the secret information in the form of 140 tune patterns in the complete Song poetry poems, to generate converted Song poetry with versification, sentence pattern and word class completely same as the original Song poetry.The experiment result indicated that the success rate of word segmentation of this scheme was up to 100%, and embedding rate of secret information to a maximum of 20.2%, characterized by high running speed, strong stealthiness and high safety when compared with Song poetry dictionary constructing algorithm based on statistics.关键词
