16.6: Other Secret Keeping Methods

( \newcommand{\kernel}{\mathrm{null}\,}\)

While this chapter has focused on cryptography methods for keeping a message secure, there is another area of secret keeping called steganography which focuses on hiding the existence of a message altogether. Historically, steganography included techniques like invisible ink, watermarks, or embedding a secret message inside a longer document that appeared unimportant. The digital age has provided many new ways to hide messages in digital photos or in the background noise of a music file.
