Summary:As a new information hiding method, coverless information hiding has become a hot issue in the field of information security. The existing coverless information hiding method can hide only one Chinese character in each natural text. However, the problem of the method is that the hiding capacity is too small. To address this problem, a new method named coverless multi-keywords information hiding method based on text is proposed in this paper. The main idea of the method is that both the keywords and their number will be hidden in the texts. Experimental results show that the proposed method can improve the capacity of the existing coverless information hiding method based on text.
