Skype is being investigated over its links to the US National Security Association (NSA) and its spy programme Prism, according to reports.
Luxembourg’s data protection commissioner is investigating the video chat and instant messenger provider after documents revealed by the Guardian raised questions about surveillance through the software.
According to the Guardian, the paper learned of the investigation through sources but so far Luxembourg’s data protection chief, Gerard Lommel, and Microsoft have declined to comment.
Skype’s headquarters are in Luxembourg and the country’s constitution prevents the passing of such private information unless sanctioned by law.
Microsoft responded to the Guardian’s reports – based on information handed over by whistleblower Edward Snowden – in July claiming that it had helped the NSA to spy on its users by insisting that the company did not provide “any government with blanket or direct access” to Skype or other products.
