摘要：The rapid advancement of technology has changed the way of our living. Sharing information becomes inevitable in everyday life. However, it encounters many security issues when dealing with secret or private information. The transmission of such sophisticated information has become highly important and received much attention. Therefore, di?erent methods have been exercised for hiding information. Graph Steganography (Graphstega) is a method of hiding information by translating it to plotted data in a graph. Due to numerous usages of graphs in our daily life, graphstega can hide information without arising any suspicion. This paper proposes a new approach of graph realization for graphstega that looks like innocent and unnoticeable to contemporary steganalytic attacks so that the message can only be detected by its intended recipient. The secret message is first translated to prefix codes using hu??man encoding. Then prefix code for separate word in the message is plotted in the graph. Thus, the approach gives high imperceptibility avoiding noise unlike other steganographic approaches and high embedding capacity due to prefix presentation and word by word encoding. The numerical experiments demonstrate the integrity of the secret message while encoding??decoding and strong durability of the proposed approach against steganalytic attacks.
