Evercookie (also known as supercookie[1]) is a JavaScript application programming interface (API) that identifies and reproduces intentionally deleted cookies on the clients' browser storage.[2] It was created by Samy Kamkar in 2010 to demonstrate the possible infiltration from the websites that use respawning.[3] Websites that have adopted this mechanism can identify users even if they attempt to delete the previously stored cookies.[4]
In 2013, Edward Snowden leaked a top-secret NSA document that showed Evercookie can track Tor (anonymity networks) users.[5] Many popular companies use functionality similar to Evercookie to collect user information and track users.[1][6] Further research on fingerprinting and search engines also draws inspiration from Evercookie's ability to track a user persistently.[4][5][7]
