A novel steganography technique is realized by utilizing aerial-imaging optical system based on aerial imaging by retro-reflection (AIRR). Transparent objects in a complex shape are placed in plane-symmetrically with respect to the beam splitter in AIRR. Transparent objects of various shapes were used to confirm the decoded aerial images.
