Steganography is the method of hiding secret message information in various cover media like text, image, audio, video and others without raising suspicion to intruders about the existence of any such information. Exploiting Modification Direction (E

This paper proposes a fuzzy edge detection based steganography approach to effectively hide data within images. Instead of applying conventional edge detection algorithms, the method uses a fuzzy edge detection approach in order to estimate more numb

An improved exploiting modification direction-based image steganography technique has been proposed. The cover image is decomposed into non-overlapping units of n pixels each to embed 2 kn -ary numbers in row major order. Here, k is the number of bit
