Microsoft received 37,196 requests from law agencies between January to June 2013, according to a transparency report released by Microsoft on Friday.
The second Law Enforcement Requests Report discloses the number of requests for Microsoft data from law enforcement agencies.
Microsoft said 2.19 percent of total requests resulted in the disclosure of customer content data and 92 percent of requests that resulted in the disclosure of customer content were from US law enforcement agencies.
While Microsoft said it sees requests from a large number of countries, 73 percent of requests come from five countries: the US, Turkey, Germany, the UK and France. For Skype in particular, the requests were also concentrated, with the US, UK, France and Germany accounting for over 70 percent of requests.
“Law enforcement sought information about only a tiny fraction of the millions of end users of our enterprise services, such as Office 365,” Microsoft said. “We received 19 requests for e-mail accounts we host for enterprise customers, seeking information about 48 accounts.”
Microsoft said it disclosed customer data in response to five of those requests, and in all but one case, was able to notify the customer. Microsoft said it rejected the request or redirected law enforcement to obtain the information from the customer directly in thirteen of those cases.
Currently, Microsoft is petitioning the federal government for permission to publish more detailed data relating to legal demands it receives in relation to FISA.
Microsoft, Google, Facebook and others have released transparency reports in the past to give their users an idea of the type of requests for data received from law enforcement agencies, and the ways in which they respond to those requests. In April, web hosting provider LeaseWeb released its first transparency report which looked into requests related to its dedicated hosting and cloud services.
