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.

Abstract: A first raw value of a first field from the first set of fields is encrypted to generate a first token using a symmetric key encryption mechanism based on a first cryptographic key associated with a first time window after which the first cryptographic key is no longer valid for tokenization of raw fields of raw log records. After the first time window has elapsed, a second raw value of a second field from the second set of fields is encrypted to generate a second token using the symmetric key encryption mechanism based on a second cryptographic key that is different from the first cryptographic key. The second cryptographic key is associated with a third time window that occurs after the first time window and after which the second cryptographic key is no longer valid for tokenization of raw fields of raw log records.
