1. The controller shall keep logs for any of the following processing operations in automated processing systems: the collection, alteration, access, consultation, disclosure, including transfers, combination and erasure of operational personal data. The logs of consultation and disclosure shall make it possible to establish the justification for, and the date and time of, such operations, the identification of the person who consulted or disclosed operational personal data, and, as far as possible, the identity of the recipients of such operational personal data.

2. The logs shall be used solely for verification of the lawfulness of processing, self-monitoring, ensuring the integrity and security of the operational personal data, and for criminal proceedings. Such logs shall be deleted after three years, unless they are required for ongoing control.

3. The controller shall make the logs available to its data protection officer and to the European Data Protection Supervisor on request.
