Des tests montrent que les chatbots IA peuvent révéler des informations personnelles

Des expériences récentes menées par CNET ont révélé que certains chatbots d'IA populaires fournissent des informations personnelles, telles que des adresses et des numéros de téléphone, lorsqu'ils y sont invités. Grok s'est montré le plus enclin à partager des données, tandis que d'autres ont refusé. Ces résultats soulignent les risques persistants en matière de confidentialité liés à ces outils.

Le personnel de CNET a testé plusieurs chatbots de premier plan en leur demandant des détails personnels sur eux-mêmes et sur leurs proches.
