Une technologie audacieuse qui pourrait se r\u00e9v\u00e9ler b\u00e9n\u00e9fique dans des situations d&#8217;urgence ou de grande affluence.<\/p>\n\n\n\n<p>Lorsqu&#8217;on \u00e9voque les pionniers du num\u00e9rique, on pense souvent imm\u00e9diatement \u00e0 Mark Zuckerberg, Steve Jobs ou Elon Musk. N\u00e9anmoins, Jack Dorsey, \u00e0 la fois fondateur de Twitter et Bluesky, est consid\u00e9r\u00e9 comme un pr\u00e9curseur de la communication num\u00e9rique. Le 28 juillet, l&#8217;informaticien am\u00e9ricain a pr\u00e9sent\u00e9 sa derni\u00e8re application, Bitchat, promettant \u00e0 ses utilisateurs une communication sans faille.<\/p>\n\n\n\n<p>Les d\u00e9veloppeurs ont remarqu\u00e9 que les r\u00e9seaux internet sont souvent congestionn\u00e9s lors de concerts et d&#8217;\u00e9v\u00e9nements majeurs. Les appareils de communication en ligne peuvent aussi devenir non fonctionnels suite \u00e0 des catastrophes naturelles. C&#8217;est \u00e0 ce moment-l\u00e0 que Bitchat intervient. But : offrir aux utilisateurs la possibilit\u00e9 de communiquer en cas d&#8217;indisponibilit\u00e9 des r\u00e9seaux.<\/p>\n\n\n\n<p>Les ing\u00e9nieurs de Bitchat ont opt\u00e9 pour la technologie Bluetooth \u00e0 faible consommation, une solution \u00e9conome en \u00e9nergie. Ce dispositif de transmission, qui se sert d&#8217;appareils Bluetooth \u00e0 proximit\u00e9, a une port\u00e9e de 300 m\u00e8tres. Gr\u00e2ce \u00e0 la messagerie, il est possible de communiquer avec des contacts situ\u00e9s pr\u00e8s de sa propre localisation, sans n\u00e9cessit\u00e9 d&#8217;enregistrer une adresse \u00e9lectronique ou un num\u00e9ro de t\u00e9l\u00e9phone. L&#8217;utilisateur ne doit pas non plus cr\u00e9er de compte, car il est directement dirig\u00e9 vers une fen\u00eatre de conversation regroupant les autres utilisateurs.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>L&#8217;engagement d&#8217;une confidentialit\u00e9 compl\u00e8te<\/strong><\/p>\n\n\n\n<p>L&#8217;interface de Bitchat est \u00e9pur\u00e9e, comparable au langage d&#8217;un logiciel de codage. Les communications sont chiffr\u00e9es, temporaires et ne subsistent que dans la m\u00e9moire de l&#8217;appareil. Ce syst\u00e8me assure un cryptage de bout en bout. Dans un souci de s\u00e9curit\u00e9 maximale, un mode \u00ab panique \u00bb supprime imm\u00e9diatement toutes les donn\u00e9es si le logo de l&#8217;application est touch\u00e9 trois fois.<\/p>\n\n\n\n<p>Con\u00e7ue pour fournir une assistance lors de difficult\u00e9s, cette technologie pourrait n\u00e9anmoins susciter l&#8217;int\u00e9r\u00eat d&#8217;individus malintentionn\u00e9s du fait de l&#8217;absence de contr\u00f4le sur la messagerie. C&#8217;est en ao\u00fbt 2024 que Pavel Durov, le cr\u00e9ateur de la plateforme de messagerie s\u00e9curis\u00e9e Telegram, a \u00e9t\u00e9 inculp\u00e9 par la justice fran\u00e7aise pour ce motif. On a critiqu\u00e9 le PDG pour son inaction face \u00e0 la propagation de contenus criminels ou illicites sur sa plateforme.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><em>R\u00e9dig\u00e9e par &#8220;Ons Daghfous&#8221;<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>La messagerie se distingue par sa capacit\u00e9 \u00e0 transmettre des messages par le biais de signaux Bluetooth.
