Quiz sur les deepfakes

Les réponses et les explications apparaissent au fur et à mesure que vous répondez au quiz.

1. Un message vocal demande un changement de compte sensible. Comment le destinataire doit-il le vérifier ?
   • Contactez la personne via un canal de confiance déjà enregistré
   • Utiliser les coordonnées incluses dans le message suspect
   • Considérez la similarité des voix comme une preuve suffisante
   • Demander à l'expéditeur de répéter la demande
2. A detector labels a clip as synthetic. What does its score establish?
   • Proof that a specific person created it
   • A signal that needs context, not a definitive verdict
   • Proof that the event depicted never happened
   • A guarantee that the media is authentic
3. Why might a convincing image still be misleading?
   • Only audio can be manipulated
   • Visual realism proves provenance
   • Synthetic or manipulated media can depict events that did not occur
   • A content credential verifies every scene claim
4. What factors matter when deciding whether media manipulation is appropriate?
   • Whether the edit is difficult to detect
   • Only technical quality
   • The file’s resolution
   • Consent, disclosure, purpose, and rights of depicted people
5. What do provenance records or content credentials prove by themselves?
   • They prove that all depicted events occurred
   • They can show recorded history but do not prove every claim in the scene
   • They identify every editor with certainty
   • They establish consent for every use
6. A reporter investigates a suspicious clip. What should they preserve?
   • A detector score without the file
   • Only a compressed social-media preview
   • Original media and provenance information
   • An edited copy that removes metadata
7. When should synthetic media be labeled on publication?
   • When viewers might otherwise be misled
   • Only when the file is low resolution
   • Never if a detector did not flag it
   • Only when the subject complains
8. A recording is genuine, but a short crop removes the preceding question and changes the apparent meaning. What does this illustrate?
   • Only synthetic media can mislead
   • A genuine file proves every claim made about it
   • A detector can reconstruct all missing context
   • Authentic media can still mislead through cropping or relabeling
