Abstract

L’invention concerne un appareil permettant de déterminer les réglages de confidentialité d’objets média, qui peut comprendre un processeur. Le processeur peut être configuré pour recevoir des données de capture d’objet média associées à un objet média. Les données de capture d’objet média peuvent comprendre au moins un lieu de capture. Le processeur peut également être configuré pour identifier un contexte de confidentialité qui correspond aux données de capture d’objet média. À cet égard, le lieu de capture des données de capture d’objet média peut se situer dans une zone géographique du contexte de confidentialité. Le processeur peut en outre être configuré pour déterminer un réglage de confidentialité de l’objet média en fonction du contexte de confidentialité correspondant et, dans certains modes de réalisation, pour commander l’accès à l’objet média en fonction du réglage de confidentialité déterminé. L’invention concerne également des procédés associés, ainsi que des produits-programmes informatiques.
