Tracker Guidance

Design the high-risk AI system with logging capabilities that automatically record relevant events over the system's lifetime to the extent appropriate for its intended purpose and support traceability.

Official text

Article 12Official source
1. High-risk AI systems shall technically allow for the automatic recording of events (logs) over the lifetime of the system. 2. In order to ensure a level of traceability of the functioning of a high-risk AI system that is appropriate to the intended purpose of the system, logging capabilities shall enable the recording of events relevant for: (a) identifying situations that may result in the high-risk AI system presenting a risk within the meaning of Article 79(1) or in a substantial modification; (b) facilitating the post-market monitoring referred to in Article 72; and (c) monitoring the operation of high-risk AI systems referred to in Article 26(5). 3. For high-risk AI systems referred to in point 1 (a), of Annex III, the logging capabilities shall provide, at a minimum: (a) recording of the period of each use of the system (start date and time and end date and time of each use); (b) the reference database against which input data has been checked by the system; (c) the input data for which the search has led to a match; (d) the identification of the natural persons involved in the verification of the results, as referred to in Article 14(5).
