Microsoft is accused installing "back doors" for the USA government to access customer communications. The software giant opened a center in Brazil on Wednesday where officials will be able to inspect its programming code.

The world's biggest software company showed off its fourth 'Transparency Center' in Brasilia where experts from Latin America and the Caribbean will be able to view the source code of its products.

After the former NSA contractor, Edward Snowden leaked documents in 2013 that was capturing massive amounts of data from emails in the major US technology companies including Microsoft. In order to build trust follows by heightened suspicious Microsoft opened this center in Brazil.

The centers in Brazil contains reinforced walls and comes with strict security procedures, including the banning of electronic devices, local servers without the internet can display copies of code for its email and server products. The copies are deleted, reported by Reuters.

Viewers can use software tools to examine the code. This was not immediately clear whether experts would be able to run deep code analysis necessary to uncover back doors or other bugs, said by Microsoft.

However, it is by no means certain the effort by Microsoft will diminish concerns about spying, but the Brazil's reaction to the opening up a new center for the Software Company was initially positive. The centers allow for face to face discussion between government experts and developers.

This center is showing that there are no traps, it is good to step", said by Brazilian Government officials. The software giant also established other codes inspection side in other parts of the word. The first sight is located in Redmond, Washington in 2014. Other sites are located in Brussels and Singapore. Another transparency center will be coming next month in Beijing, reported by W Tech Week Europe

"Governments can verify for themselves that there are no back doors," said Mark Estberg, senior director of Microsoft's global government program.
