Abstract
A method and apparatus for tokenization of user-traceable data are described. User traceable data is data that is not directly personal data but can be traced back to the identity or an activity of the user. A first raw value is encrypted into a first token using a symmetric key encryption mechanism based on a combination of a second raw value including personal data of a user and a second token resulting from the tokenization of the second raw value where the first token is an anonymized representation of the first raw value.
