Quote: Secret codes have been used throughout history to send messages. During the time of Harriet Tubman, for example, people
created their own code as secret language to help slaves escape. These
codes would often be used in songs by slaves to communicate with each
other without their master being aware. Secret codes can also be used in
the form of art, symbols, words, riddles, or numbers. They help keep
information safe. Johnson, Michael. “Secret Messages." Keeping Safe.
