Microsoft has a patent obtained on silently recording communications, in which the special redirection of voip calls for shooting lists. The request stems from to the Skype acquisition.
The patent application was at the end of 2009, under the heading of Legal Intercepts submitted and 23 June received Microsoft patent assigned to it. The text describes how data for the establishment of communication can be modified so that calls via the internet, along an alternative route will be redirected. Somewhere in route to a recording capability, to be the communication silently, describes the patent.
Microsoft clarified further in the document that governments developed methods to traditional phone lines to drain it, but that they do not work in conjunction with voip and other new communications technologies. The company has continued to save the copies of the saved sessions, then to, for example, law enforcement agencies can be controlled.
The patent was filed before Microsoft Skype took over. Although the technology might be for providers, and similar parties makes it easier to meet obligations of governments to internet communications, to hand over, says nothing about the deciphering of encrypted traffic such as Skype. About Skype, is already years of speculation that there is a backdoor that the U.s. intelligence traffic can decrypt it, but hard evidence for this was never found.
