JPEG Reversible Data Hiding with Matrix Embedding

Joint photographic experts group (JPEG) image is the most popular image format used in our daily life. Different from the reversible data hiding (RDH) in spatial domain image, JPEG RDH needs to consider not only the visual quality, but also the file storage size of the marked image. In this paper, we firstly implement the matrix embedding (which is originated from steganography) strategy into the field of JPEG RDH. Via considering the philosophy behind the JPEG encoder, those quantized discrete cosine transform (DCT) coefficients that may introduce less distortion are adaptively selected for modification in the embedding process. Experimental results demonstrate that higher visual quality and less storage size of the marked JPEG image can be obtained compared with the state-of-the-art methods.
