Reversible multiple messages embedding using reflective blocks

This paper proposes three multiple messages embedding (MME) methods as extension for reversible data embedding using reflective blocks [1]. MME is realized by exploiting the data representation scheme in [1] while maintaining the reversibility and scalability of [1]. In particular, Method I utilizes block range to embed multiple messages while Method II utilizes bit representation to realize MME. Both of these methods can each embed a maximum of 9 messages in a host image. Method III is the hybrid of Method I and II, and it can embed up to 37 messages in a host image. Experimental results show the average embedding capacity for each individual embedding channel.
