This paper focuses on countering data hiding in images. Specifically, we refer to the active
warden problem, a process which aims at disrupting the covert communications that are
possibly taking place within host media. Although this has been extensively studied in the
literature, typical state of the art approaches treat the hidden message as a noise-like
component, proposing de-noising techniques, lossy compression or noise addition as a
countermeasure. In this paper we present novel approach called Lesser Components …
This paper focuses on countering data hiding in images. Specifically, we refer to the active warden problem, a process which aims at disrupting the covert communications that are possibly taking place within host media. Although this has been extensively studied in the literature, typical state of the art approaches treat the hidden message as a noise-like component, proposing de- noising techniques, lossy compression or noise addition as a countermeasure. In this paper we present novel approach called Lesser Components Distortion (LCD) that aims at disrupting the covert communication while minimizing distortion on the host medium. Although stemming from insights gained from notable works in the spread spectrum steganography field, we prove through extensive testing that it shows remarkable effectiveness against steganographic techniques in general, compared to common attacks.
