steganography

steganography (steg-[schwa]-nog-r[schwa]-fee), n. A cryptographic method that digitally embeds or encodes one item of information within another. • Because a digitized audio or visual file usu. has unused data areas, indelible (and nearly undetectable) information can be added without altering the file’s quality. Copyright or trademark tags can be hidden in every fragment of a digital work, making disassociation almost impossible. — Also termed digital fingerprinting; digital watermarking.
