Logging
Article 25
1. Member States shall provide for logs to be kept for at least the following processing operations in automated processing systems: collection, alteration, consultation, disclosure including transfers, combination and erasure. The logs of consultation and disclosure shall make it possible to establish the justification, date and time of such operations and, as far as possible, the identification of the person who consulted or disclosed personal data, and the identity of the recipients of such 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 personal data, and for criminal proceedings. 3. The controller and the processor shall make the logs available to the supervisory authority on request.
