Research on a Robust Method for Image Steganography Transmission in Network

ABSTRACT

Images carrying the important information are often cracked by hackers when they are transmitted in the network. We propose a method in the paper for avoiding information leakage. It presents some significant evaluation parameters to analyze image scrambling algorithms for encryption level. Then images are encrypted with the algorithm and transmitted in the network by hiding in the open video. In order to prevent the loss of packet or frame, we advance a robust data hiding method which can use paired-coefficient and BCH code to recover error bit. It encodes the secret information with different BCH codes and embeds them into the paired-coefficients positions. The experimental results show that the method can avert intra-frame distortion drift and achieve high error resilience capacity. The research has a certain reference value and guiding significance for image steganography.
