Brazil's president signed into law…a "Bill of Rights"…that aims to protect online privacy and promote the Internet as a public utility by barring telecommunications companies from charging for preferential access to their networks. The law signed by President Dilma Rousseff at a global conference on the future of Internet governance puts Brazil in the vanguard of online consumer protection and what is known as "net neutrality," whose promoters consider it…democratic…because it keeps financial barriers for innovators low…[It]…promotes privacy by limiting the data that online companies can collect on Internet…, deeming communications over the Internet "inviolable and secret." Service providers must develop protocols to ensure email can be read only by senders…Violators are subject to penalties...The law obliges Internet companies…to hold on to user data for six months and hand it over to law enforcement under court order…[refers to Petrobras]
