In recent years, the advancement and spread of social network technology have made the use of social network behavior for steganography a prominent topic in steganography research. Social networks host vast multimedia data and encompass diverse interactions, including Likes, Reposts, and Comments. These interactions can be strategically leveraged for steganography. This study proposes a novel behavior-based steganography method that employs “Like” and “Comment” interactions in social networks to transmit a secret message bitstream. This behavior-based steganography method offers an effective solution for social network steganography, enabling secret message transmission through network behaviors while ensuring strong resistance to steganalysis, security, and robustness.
