Text information hiding has attracted the attention of many researches and has made many achievements. However, the existing text information hiding methods like text format-based, generation method-based, text image-based etc., has an obvious flaw namely they cannot resist steganography detection. Based on the rank map of the words, we present a novel method of coverless text information hiding. Firstly, the proposed method directly generates stego-vectors from the secret message by using the rank map. Then, some normal texts, stego-texts including the generated sgeto-vectors, will be searched from the text big data. Finally, the secret information can be sent to the receiver without any modification of the stegotexts. The proposed algorithm has a higher theoretical significance and practice value because it is able to escape from almost all state-of-the-art steganalysis methods.
