A newly patented Microsoft technology named Legal Intercept that would allow the company to covertly intercept, monitor and record Skype calls is raising privacy concerns.
Microsoft’s patent application for Legal Intercept was filed in 2009, well before the company’s $8.5 billion purchase of Skype this May. The patent was granted last week.
From Microsoft’s description of the technology in its patent application, Legal Intercept appears similar to tools used by telecommunication companies and equipment makers to comply with government wiretap and surveillance requests.
According to Microsoft, Legal Intercept is designed to silently record communications on VoIP networks such as Skype.
According to Microsoft, Legal Intercept fixes the gaps in current monitoring tools that are designed mainly for intercepting Plain Old Telephone Service (POTS). “With new Voice over Internet Protocol (VoIP) and other communication technology, the POTS model for recording communications does not work,” Microsoft noted in the patent application.
Michael Froomkin, a professor of law at the University Of Miami School Of Law, said that from the patent description it sounds as if the technology would allow Microsoft to do is make Skype CALEA capable.
