La soci\u00e9t\u00e9 Google a exprim\u00e9<\/a><\/noindex> pour une initiative Privacy Sandbox<\/a><\/noindex>, dans le cadre de laquelle plusieurs API ont \u00e9t\u00e9 propos\u00e9es pour mise en \u0153uvre dans les navigateurs, permettant de trouver un compromis entre le besoin des utilisateurs de pr\u00e9server leur confidentialit\u00e9 et le d\u00e9sir des r\u00e9seaux publicitaires et des sites de suivre les pr\u00e9f\u00e9rences des visiteurs. <\/p>\n

La pratique montre que la confrontation ne fait qu'aggraver la situation. Par exemple, l'introduction de blocages des cookies utilis\u00e9s pour le suivi a conduit \u00e0 une utilisation plus intensive de techniques alternatives, telles que les m\u00e9thodes d'identification indirecte (browser fingerprinting), qui tentent de distinguer l'utilisateur de la masse g\u00e9n\u00e9rale en se basant sur les param\u00e8tres sp\u00e9cifiques utilis\u00e9s (polices install\u00e9es, types MIME, modes de cryptage, etc.) et des caract\u00e9ristiques mat\u00e9rielles (r\u00e9solution d'\u00e9cran, artefacts sp\u00e9cifiques lors du rendu, etc.). <\/p>\n

Google propose de fournir un Floc API<\/a><\/noindex>, qui permettra aux r\u00e9seaux publicitaires de d\u00e9finir la cat\u00e9gorie d'int\u00e9r\u00eats de l'utilisateur, mais ne permettra pas l'identification individuelle. L'API fonctionnera avec des groupes d'int\u00e9r\u00eats g\u00e9n\u00e9raux, englobant de grandes masses d'utilisateurs anonymis\u00e9s (par exemple, \u00ab amateurs de musique classique \u00bb), mais ne permettra pas de manipuler les donn\u00e9es au niveau de l'historique de navigation de sites sp\u00e9cifiques. <\/p>\n

Pour mesurer l'efficacit\u00e9 des publicit\u00e9s et \u00e9valuer la conversion des clics, il y a le d\u00e9veloppement du Conversion Measurement API<\/a><\/noindex>, qui permet d'obtenir des informations agr\u00e9g\u00e9es sur l'activit\u00e9 des utilisateurs sur un site apr\u00e8s avoir cliqu\u00e9 sur une publicit\u00e9.<\/p>\n

Pour distinguer les activit\u00e9s douteuses et les spammeurs de l'ensemble des utilisateurs (comme le clic frauduleux ou la r\u00e9alisation de transactions factices pour tromper les annonceurs et les propri\u00e9taires de sites), un Trust Token API<\/a><\/noindex>, bas\u00e9 sur le protocole Privacy Pass, qui est d\u00e9j\u00e0 utilis\u00e9 par CloudFlare pour classifier les utilisateurs de Tor. L'API permet de distinguer les utilisateurs dignes de confiance de ceux qui ne le sont pas, sans recourir \u00e0 des identifiants intersites.<\/p>\n

Pour pr\u00e9venir l'identification indirecte, une technique est propos\u00e9e, Privacy Budget<\/a><\/noindex>L'esprit de la m\u00e9thode est que le navigateur ne fournit des informations pouvant potentiellement \u00eatre utilis\u00e9es pour l'identification que dans une certaine mesure. Si la limite du nombre de requ\u00eates \u00e0 l'API est d\u00e9pass\u00e9e et que la divulgation d'autres informations pourrait violer l'anonymat, l'acc\u00e8s \u00e0 certaines API est bloqu\u00e9.<\/p>\n
