Dubbed "Legal Intercept," using the technology means "data associated with a request to establish a communication is modified to cause the communication to be established via a path that includes a recording agent" that silently records the data, according to a filing with the U.S. Patent and Trademark Office.
In other words, the technology intercepts Internet communications data so it can be recorded for the purposes of reviewing it later by, presumably, government or law-enforcement officials.
"Sometimes, a government or one of its agencies may need to monitor communications between telephone users," Microsoft said in the filing, describing how a recording device can be placed at a central office to record communications over a traditional telephone network.
But with Voice over IP and other Internet-based communications, "the [conventional] model for recording communications does not work," according to Microsoft.
The company filed for the patent on Dec. 23, 2009, and patent number 20,110,153,809 for the technology was granted on June 23.
Microsoft declined to comment about if and how it plans to use the technology and if it plans to possibly sell it to the federal government, according to a spokesperson reached via email.
It's no secret the federal government is looking for better ways to legally intercept Internet communications, and that it feels hampered by the inadequate ways to do so at the moment.
FBI officials have complained at length about the "going dark" problem, which refers to their inability to intercept electronic communications in a timely and efficient fashion even when they have a warrant to do so.
Part of the problem is that companies that have access to the communications don't have the capability to access it and get it in the hands of officials quickly and efficiently.
It's unclear whether the technology Microsoft patented will help alleviate this problem, but as described in the patent fling, it certainly should make it easier to record Internet-based communications delivered via a variety of means--including Voice over Internet Protocol, smartphones, PCs, set-top boxes, and Internet-based gaming devices such as Microsoft's own Xbox.
