Polish professor Wojciech Mazurczyk discovered a way to encrypt secret messages into silence on Skype to hide calls from hackers, authorities, or other prying eyes. Mazurczyk, from the Warsaw University of Technology found a way to hide data in the 70-bit packets that Skype sends by default when it’s detecting silence, the moments in between speech when you’re not talking. "There are concerns that Skype calls can be intercepted and analysed," says Mazurczyk at the Institute of Telecommunications in Warsaw, Poland in New Scientist. SkypeHide will let users cloak extra, non-chat messages during a call. New American reports, "Microsoft does have a patent application in process called “Legal Intercept” that enables the ability to record “any kind of voice-over-Internet-protocol (VoIP) communications” by re-routing messages over “a path that includes a recording agent.” Read the full story in New Scientist.
