1. High-risk AI systems shall technically allow for the automatic recording of events (‘logs’) over the duration of the life cycle of the system.

2. In order to ensure a level of traceability of the AI system’s functioning that is appropriate to the intended purpose of the system, logging capabilities shall enable the recording of events relevant for
    (i) identification of situations that may result in the AI system presenting a risk within the meaning of Article 65(1) or in a substantial modification;
    (ii) facilitation of the post-market monitoring referred to in Article 61; and
    (iii) monitoring of the operation of high-risk AI systems referred to in Article 29(4).

4. For high-risk AI systems referred to in paragraph 1, point (a) of Annex III, the logging capabilities shall provide, at a minimum:

1. recording of the period of each use of the system (start date and time and end date and time of each use);

2. the reference database against which input data has been checked by the system;

3. the input data for which the search has led to a match;

4. the identification of the natural persons involved in the verification of the results, as referred to in Article 14 (5).
