4. In cryptography, steganography refers not only to the obfuscating (encrypting) data, but hiding the fact that it even exists.
5. The art and science of hiding information by embedding messages within other, seemingly harmless messages.

Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks ) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images. Unlike encryption, steganography cannot be detected. Therefore, it is used when encryption is not permitted; or, more commonly, steganography is used to supplement encryption.

An encrypted file may still hide much information by using steganography, so even if the encrypted file is deciphered, the hidden message is not seen. Steganography (literally, “covered writing”) dates back to ancient Greece, where common practices consisted of etching messages in wooden tablets and covering them with wax, and/or tattooing a shaved messenger’s head, letting his hair grow back, then shaving it again when he arrived at his contact point.
