In 2006 X. Zhang and S, Wang suggested efficient steganographic embedding by Exploiting Modification Direction (EMD) where each important secrecy bit is converted to (2n + 1) -ary notational system which produces by n pixel values where 1 pixel is increased or decreased. To date, many researchers have implemented EMD algorithms that are less secure and produce less embedding capacity and imperceptibility. So, to reduce these limitations a combination of audio-video crypto-steganography using the Digital Forensic Detection Array EMD (DFDAEMD) algorithm is used. It uses (3m2 + 4 m + 2) ary notation to embed three pixels at a time for enhancing the embedding capacity and security of secret data. The observed and verified software results confirm that the implemented security model provides better Authentication, Imperceptibility, Robustness, Embedding Capacity (EC), Embedding Rate (ER), and very good recovery of both secret and original data as compared to any existing EMD methods.
