Topic: Big Data
In today's information-oriented societies, the information is a weapon. Therefore, the information is encrypted and is transmitted to the legitimate parties. However, messages made by cryptography are unnatural, and eavesdroppers can easily target these encrypted messages. That is why steganography is proposed. Steganography is a technique hiding secret information within innocent-looking information (e.g., text, audio, image, video, and so on). In this paper, the authors propose a stegosystem that uses not only cover data as media transmitting secret messages but also cover data as information recovering secret messages.
