Reversible data hiding (abbreviated as RDH), also called as lossless or erasable data hiding, has experienced more than 20 years of development, from a capacity of only hundreds of bits to a capacity of exceeding 1 bpp (bit per pixel), from traditional spatial domain to compressed domain (e.g., vector quantization, joint photographic experts group), from natural images to encrypted images, from images to video or audio, from fragile authentication to semi-fragile (or robust) RDH, etc.. During these two decades, a considerable amount of attention has been devoted to study RDH, and more and more papers in various research branches of RDH have been published. In this paper, we will give a detailed introduction on RDH from the following five aspects: 1) RDH in the traditional spatial domain; 2) RDH in the compressed domain; 3) RDH for encrypted images; 4) semi-fragile authentication RDH; 5) video and audio RDH.
