Covert information sharing with novel fuzzy adaptive edge detection

Abstract

The secure communication systems should provide covert, stealth, or unauthorized detection of critical information. Covert communication systems not only shield the secure information enclosed in the cover data from being decoded but also avoid the opponent from perceiving the transmission. In this paper, we propose adaptive Fuzzy Edge detection‐based covert communication. The proposed system is capable of locating the accurate edge zones of a cover picture to shield the secure information. Experimental outcomes show that the proposed strategy has accomplished good imperceptibility compared with the other analogous strategies.
