Destructive Method with High Quality and Speed to Counter Information Hiding

摘要

Hidden information behavior is becoming more difficult to be detected, causing illegal information spreading. To counter information hiding, more complex and high-dimensional steganalysis methods are applied, and have good detection for some specific information hiding algorithms. However, huge time consumption is needed and only suitable for offline usage with this method. In this paper, a destructive method with high quality and speed is proposed to counter information hiding. The experimental result presents that the extracting error rate of hiding information is around 50%, which means the method can destroy the possible covert communication completely. At the same time, the quality of covers after the destructive operation is good and the average time of operating an image is millisecond.
