Las empresas Cloudflare, Google, Mozilla, Microsoft y Shopify han presentado un proyecto conjunto para desarrollar y estandarizar el protocolo Private Access Control Tokens (PACT), que permite distinguir a los usuarios reales y a los bots leg\u00edtimos del tr\u00e1fico basura y la actividad incontrolada de bots de IA, manteniendo la privacidad del usuario. Se afirma que el nuevo protocolo permitir\u00e1 filtrar el tr\u00e1fico de bots en los sitios web usando tokens an\u00f3nimos, sin necesidad de solicitar captchas, autenticaci\u00f3n obligatoria ni rastreo a trav\u00e9s de cookies. <\/p>\n

La idea es que los servicios que tengan motivos para considerar al usuario como una persona real, por ejemplo, despu\u00e9s de una autenticaci\u00f3n exitosa o una verificaci\u00f3n anti-bot, emitir\u00e1 tokens an\u00f3nimos al usuario. Despu\u00e9s de esto, el navegador del usuario podr\u00e1 presentar estos tokens a otros sitios como confirmaci\u00f3n de que la solicitud no es autom\u00e1tica. Este enfoque permitir\u00e1 utilizar las verificaciones realizadas en un sitio para conectarse a otros sitios sin verificaciones adicionales. Al mismo tiempo, el protocolo se dise\u00f1a de manera que los sitios no puedan usar los tokens para identificar al usuario o recuperar el historial de visitas. <\/p>\n

El motivo de la iniciativa fue el aumento de la proporci\u00f3n de tr\u00e1fico automatizado de agentes de IA, rastreadores (crawlers) y scraping (scrapers), que se hacen pasar por solicitudes de usuarios normales, ignorando las reglas de robots.txt y creando una enorme carga parasitaria en servidores<\/a>. Anteriormente, Cloudflare hab\u00eda propuesto utilizar el mecanismo Web Bot Auth para la autenticaci\u00f3n de bots, basado en adjuntar una firma criptogr\u00e1fica a las solicitudes HTTP de los bots para tomar decisiones sobre el acceso en funci\u00f3n de datos verificables, y no IP<\/a> o contenido f\u00e1cilmente falsificable del campo User-Agent. <\/p>\n

Entre los riesgos potenciales asociados con la implementaci\u00f3n del protocolo PACT se menciona que el mecanismo, creado para la verificaci\u00f3n voluntaria del usuario, podr\u00eda convertirse en un filtro de acceso obligatorio a los sitios y convertirse en una barrera, donde programas, navegadores y usuarios tendr\u00edan que demostrar que merecen acceso.<\/p>\n

La organizaci\u00f3n EFF (Electronic Frontier Foundation) ya hab\u00eda se\u00f1alado un problema similar en su cr\u00edtica al API de Integridad del Entorno Web y la certificaci\u00f3n remota. Estos mecanismos permiten a los propietarios de sitios web bloquear navegadores, sistemas operativos y herramientas de automatizaci\u00f3n indeseadas, present\u00e1ndolo como una lucha contra el fraude y la actividad maliciosa. EFF reconoce que los problemas con los bots son reales, pero considera inaceptable abordarlos mediante la implementaci\u00f3n de nuevas restricciones y la limitaci\u00f3n del derecho del usuario a gestionar su propio ordenador.
