History and evolution of steganography steganographic techniques have been used for ages and they date back to ancient greece the aim of steganographic communication back then and now, in modern applications, is the same: to hide secret data (a steganogram) in an innocently looking cover and send it to the proper recipient who is aware of the information hiding procedure. Cryptography in japan seems not to have been used until about 1510, and advanced techniques were not known until after the opening of the country to the west beginning in the 1860s during the 1920s, it was polish naval officers who assisted the japanese military with code and cipher development.
