Inspecter l'image pour identifier les données sensibles avec des infoTypes

Pour inspecter une image à la recherche de données sensibles, vous devez envoyer une image encodée en base64 à la méthode content.inspect de l'API DLP. Cloud DLP recherche les infoTypes les plus courants, à moins que vous ne spécifiez des types d'informations spécifiques (infoTypes) à rechercher.
