Abstract: This paper proposes a time interval-based social behavior information hiding algorithm. First, both sender and receiver store the user information of the social relationship shared by both parties; then, the sender binds the key, and hides secret information during the time interval between social interactions such as "liking"; finally, the receiver extracts secret information by periodically acquiring the behavioral information of co-shared social users. Experiment is conducted by taking the popular QQ social platform as research object, and experimental results show that the method can significantly improve the capacity of secret information transmission with a low time cost. The proposed method is not subject to any particular social platforms, and therefore has good applicability.

Key words: behavioral information hiding, social platforms, time interval
