A/78/310 Report of the Special Rapporteur on the right to privacy, Ana Brian Nougrères Principles of transparency and explainability in the processing of personal data in artificial intelligence Summary In the present report, the Special Rapporteur on the right to privacy, Ana Brian Nougrères, stresses the importance of the principles of transparency and explainability in the processing of personal data using artificial intelligence. The omnipresence of artificial intelligence in all activities and decision-making about people using artificial intelligence demand that the issue be examined and that measures be taken to ensure that the use of artificial intelligence is ethical, responsible and human rights-compliant. This is important because transparency and explainability not only help to build trust and reliability in artificial intelligence, but also contribute to the protection of human rights. These principles allow individuals affected by artificial intelligence to be informed in a timely, comprehensive, simple and clear manner about basic issues concerning the use of their personal information in artificial intelligence processes or projects and the consequences thereof, and about the specific reaso ns behind such use. This makes it possible for them to exercise their rights, such as the right to due process and to a defence when faced with decisions made using artificial intelligence tools or technologies. 2/20 23-15851
