==== Social steganography ====
In communities with social or government taboos or censorship, people use cultural steganography—hiding messages in idiom, pop culture references, and other messages they share publicly and assume are monitored. This relies on social context to make the underlying messages visible only to certain readers.<ref>[http://boingboing.net/2013/05/22/social-steganography-how-teen.html Social Steganography: how teens smuggle meaning past the authority figures in their lives], Boing Boing, 22 May 2013.

* Hiding a message in the title and context of a shared video or image.
* Misspelling names or words that are popular in the media in a given week, to suggest an alternative meaning.
* Hiding a picture that can be traced by using Paint or any other drawing tool.{{citation needed|date=December 2016}}
