Brasilia, April 23 (RHC) – A conference on Internet governance is set to start in Brazil in the wake of revelations about global spying activities by the United States.

Representatives from around the world will attend the two-day NETMundial summit, which begins in the Brazilian city of Sao Paulo on Wednesday.

They are expected to set out principles for governing the Internet. Reports also say that some of the countries taking part in the conference are planning to call for the creation of an international body to oversee the Internet’s technical functions.

The US is currently supervising the World Wide Web, but many countries feel betrayed following the disclosures about US on-line surveillance activities.

On Tuesday, Brazil's Senate passed a law, amounting to a web user's bill of rights. The legislation, dubbed Brazil's "Internet Constitution," sets out principles, rights and duties for both Internet users and service providers.

Brazilian President, Dilma Rousseff, is planned to sign the bill into law and present it at the conference on Wednesday.

The new law was passed following revelations that the US National Security Agency (NSA) had spied on personal communications of Brazilians, including those of Rousseff.
