Network Steganography Based on Error Correction Code

The article proposes a network steganography model based on error correcting code. The proposed method makes corrections to the contents of the network packet. The selection of the corrected packet and the modified bit in the packet is determined based on the embedding key. The embedding key is composite and contains ten parameters. The receiving party detects the modified messages and corrects them with the error correcting code. The data embedding algorithm uses an informative part of the packet. The steganographic system simulates signal transmission over a noisy channel.
