O vice-presidente do Google, respons\u00e1vel pelo projeto Privacy Sandbox, anunciou o cancelamento do plano de desativar no navegador Chrome o suporte a cookies de terceiros, que s\u00e3o criados ao acessar dom\u00ednios diferentes do dom\u00ednio da p\u00e1gina atual. Os cookies de terceiros s\u00e3o utilizados para rastrear a movimenta\u00e7\u00e3o do usu\u00e1rio entre sites nas redes de an\u00fancios, widgets de redes sociais e sistemas de web analytics. Em vez de eliminar completamente os cookies de terceiros no Chrome, o objetivo \u00e9 implementar uma nova interface que possibilite ao usu\u00e1rio decidir autonomamente se deseja bloquear esses cookies, podendo ativar ou desativar a bloqueio a qualquer momento. Os detalhes da implementa\u00e7\u00e3o ainda n\u00e3o foram divulgados, assim como n\u00e3o foi explicado como isso se diferencia da op\u00e7\u00e3o j\u00e1 existente nas configura\u00e7\u00f5es chrome:\/\/settings\/cookies \"Bloquear cookies de terceiros\". <\/p>\n
A empresa Mozilla ativou o bloqueio de cookies de terceiros por padr\u00e3o na vers\u00e3o 69 do Firefox, lan\u00e7ada em 2019. Em 2020, o bloqueio de cookies de terceiros come\u00e7ou a ser aplicado por padr\u00e3o no navegador Safari. O Google publicou suas primeiras inten\u00e7\u00f5es de descontinuar o suporte a cookies de terceiros em 2019 e planejava implementar a desativa\u00e7\u00e3o at\u00e9 2022, mas adiou o prazo para meados de 2023, depois para o quarto trimestre de 2024 e agora cancelou completamente esse plano. <\/p>\n
O plano para descontinuar o suporte a cookies de terceiros foi cancelado devido ao impacto negativo na ecossistema existente da publicidade online, que permite aos criadores de sites distribuir conte\u00fado gratuitamente. Apesar de anos de esfor\u00e7os do Google, a ind\u00fastria de publicidade online n\u00e3o estava pronta para substituir os cookies de rastreamento por novas APIs especializadas, que consideram a necessidade dos usu\u00e1rios por privacidade, como o FedCM (Gerenciamento de Credenciais Federadas, que permite criar servi\u00e7os de identifica\u00e7\u00e3o unificados), Tokens de Estado Privados (que permitem distinguir os usu\u00e1rios sem usar identificadores entre sites), T\u00f3picos (que classifica os usu\u00e1rios por grupos de interesses), P\u00fablico Protegido (targeting e an\u00e1lise de audi\u00eancia) e Relat\u00f3rios de Atribui\u00e7\u00e3o (avalia\u00e7\u00e3o da efic\u00e1cia da publicidade). <\/p>\n
As mudan\u00e7as relacionadas aos Cookies est\u00e3o sendo promovidas no \u00e2mbito da iniciativa Privacy Sandbox, que visa alcan\u00e7ar um consenso entre a necessidade dos usu\u00e1rios de preservar a privacidade e o desejo de redes de an\u00fancios e sites de rastrear as prefer\u00eancias dos visitantes. Anteriormente, tentativas de implementa\u00e7\u00e3o de substitui\u00e7\u00f5es para Cookies de rastreamento no Chrome enfrentaram resist\u00eancia na comunidade e cr\u00edticas sobre o fato de que os m\u00e9todos propostos como substitutos n\u00e3o resolvem todos os problemas, criando novos riscos, como a possibilidade de discrimina\u00e7\u00e3o dos usu\u00e1rios e a introdu\u00e7\u00e3o de um fator adicional para identifica\u00e7\u00e3o oculta e rastreamento dos movimentos do usu\u00e1rio. Recentemente, a organiza\u00e7\u00e3o de direitos digitais EFF anunciou a inclus\u00e3o na \u00faltima atualiza\u00e7\u00e3o da extens\u00e3o de navegador Privacy Badger de ferramentas para bloquear a capacidade de rastreamento de usu\u00e1rios, com base na utiliza\u00e7\u00e3o de APIs desenvolvidas no \u00e2mbito da iniciativa Privacy Sandbox. <\/p>\n
Adicionalmente, pode-se mencionar o plano mencionado no an\u00fancio da Google para adicionar ao modo de navega\u00e7\u00e3o an\u00f4nima no Chrome a possibilidade de ocultar endere\u00e7os IP<\/a> o usu\u00e1rio dos propriet\u00e1rios de sites, realizado atrav\u00e9s do envio de tr\u00e1fego n\u00e3o diretamente, mas por meio de um servidor proxy. Ao utilizar o novo modo, o servidor de destino ver\u00e1 como endere\u00e7o IP de entrada apenas o endere\u00e7o do proxy, semelhante ao uso de VPN<\/a>. Para anonimizar a solicita\u00e7\u00e3o, menciona-se a possibilidade de encadear a solicita\u00e7\u00e3o atrav\u00e9s de v\u00e1rios proxies. Nesse caso, a informa\u00e7\u00e3o do endere\u00e7o IP do cliente ser\u00e1 conhecida apenas pelo primeiro proxy, enquanto o segundo proxy na cadeia ver\u00e1 apenas o endere\u00e7o do primeiro proxy.
