Transaction-Based Pseudonyms in Audit Data for Privacy Respecting Intrusion Detection
Abstract. Privacy and surveillance by intrusion detection are potentially conflicting organizational and legal requirements. In order to support a balanced solution, audit data is inspected for personal data and identifiers referring to real persons are substituted by transaction-based pseudonyms. These pseudonyms are constructed as shares for a suitably adapted version of Shamir's cryptographic approach to secret sharing. Under sufficient suspicion, expressed as a threshold on shares, audit analyzers can perform reidentification.
