Tails was inspired by the [[Incognito LiveCD|https://web.archive.org/web/20090220133020/http://anonymityanywhere.com/]]. The Incognito author declared it to be dead on March 23, 2010, and wrote that Tails "should be considered as its spiritual successor".
Some ideas (in particular the improvements to the [[contribute/design/memory_erasure]] procedure) were borrowed from [Liberté Linux](https://dee.su/liberte).
