A empresa Google se manifestou<\/a><\/noindex> com a iniciativa Privacy Sandbox<\/a><\/noindex>, que prop\u00f4s a implementa\u00e7\u00e3o de v\u00e1rias APIs nos navegadores, permitindo um compromisso entre a necessidade dos usu\u00e1rios de preservar a privacidade e o desejo das redes de an\u00fancios e sites de rastrear as prefer\u00eancias dos visitantes. <\/p>\n

A pr\u00e1tica mostra que a confronta\u00e7\u00e3o s\u00f3 agrava a situa\u00e7\u00e3o. Por exemplo, a introdu\u00e7\u00e3o de bloqueadores de Cookies usados para rastreamento levou a um uso mais intenso de t\u00e9cnicas alternativas, como m\u00e9todos de identifica\u00e7\u00e3o indireta (browser fingerprinting), que tentam distinguir o usu\u00e1rio da massa geral, confiando nas configura\u00e7\u00f5es espec\u00edficas que ele aplica (fonts instalados, tipos MIME, modos de criptografia etc.) e caracter\u00edsticas do hardware (resolu\u00e7\u00e3o de tela, artefatos espec\u00edficos durante a renderiza\u00e7\u00e3o, etc.). <\/p>\n

O Google oferece fornecer uma Floc API<\/a><\/noindex>, que permitir\u00e1 que as redes de publicidade determinem a categoria de interesses do usu\u00e1rio, mas n\u00e3o permitir\u00e1 a identifica\u00e7\u00e3o individual. A API dever\u00e1 operar com grupos gerais de interesses, abrangendo grandes massas de usu\u00e1rios despersonalizados (por exemplo, «apreciadores de m\u00fasica cl\u00e1ssica»), mas n\u00e3o permitir\u00e1 manipular os dados ao n\u00edvel do hist\u00f3rico de visitas a sites espec\u00edficos. <\/p>\n

Para medir a efic\u00e1cia da publicidade e avaliar a convers\u00e3o de cliques, est\u00e1 sendo desenvolvido o Conversion Measurement API<\/a><\/noindex>, que permite obter informa\u00e7\u00f5es agregadas sobre a atividade dos usu\u00e1rios no site, ap\u00f3s a navega\u00e7\u00e3o por meio de um clique no an\u00fancio.<\/p>\n

Para distinguir o fluxo geral de atividades de fraudadores e spammers (por exemplo, cliques em excesso ou transa\u00e7\u00f5es falsas para enganar anunciantes e propriet\u00e1rios de sites), foi preparado o Trust Token API<\/a><\/noindex>, baseado no uso do protocolo Privacy Pass, que j\u00e1 \u00e9 utilizado pela CloudFlare para classificar usu\u00e1rios do Tor. A API permite dividir os usu\u00e1rios em confi\u00e1veis e n\u00e3o confi\u00e1veis, sem o uso de identificadores entre sites.<\/p>\n

Para prevenir a identifica\u00e7\u00e3o indireta, \u00e9 proposta uma t\u00e9cnica Privacy Budget<\/a><\/noindex>A ess\u00eancia do m\u00e9todo \u00e9 que o navegador fornece informa\u00e7\u00f5es que podem ser potencialmente usadas para identifica\u00e7\u00e3o, apenas em um determinado volume. Se o limite de chamadas \u00e0 API for excedido e a divulga\u00e7\u00e3o de mais informa\u00e7\u00f5es puder comprometer a anonimidade, o acesso a determinadas APIs ser\u00e1 bloqueado.<\/p>\n
