Cookie derivatives and methods for generating cookie derivatives are provided. A cookie derivative comprises a transformation of at least one portion of data associated with a cookie (e.g., a name and/or data value). The cookie derivative may comprise a persistent or non-persistent cookie derivative that may be stored on a user's computing device (e.g., within a browser). The cookie derivative may alternatively comprise a virtual cookie derivative that is stored on a server (e.g., in a log file, a cache, or other data storage of the server).
