Code mapping (CM) is an efficient technique for reversible data hiding (RDH)in JPEG images, which embeds data by constructing a mapping relationshipbetween the used and unused codes in the JPEG bitstream. This study presents anew framework for designing a CM-based RDH method. First, a new code mappingstrategy is proposed to suppress file size expansion and improve applicability.Based on our proposed strategy, the mapped codes are redefined by creating anew Huffman table rather than selecting them from the unused codes in theoriginal Huffman table. The critical issue of designing the CM-based RDHmethod, that is, constructing code mapping, is converted into a combinatorialoptimization problem. This study proposes a novel CM-based RDH method thatutilizes a genetic algorithm (GA). The experimental results demonstrate thatthe proposed method achieves a high embedding capacity with no signaldistortion while suppressing file size expansion.
