Steganalysis to adaptive pixel pair matching using two-group subtraction pixel adjacency model of covers

Abstract

Steganalysis has played a positive role on protection and improvement of information security. The adaptive pixel pair matching (APPM) embedded stego signal which is independent in any notational system by providing more compact neighborhood and with lower distortion. No method is known to be applicable to estimation of the APPM. In this paper, a novel… (More)
