Researchers find way to send secret messages using the VoIP app
Researchers working for the Institute of Telecommunications in Warsaw, Poland have found a way to send secret and encrypted messages using Microsoft’s utterly popular VoIP app Skype.A New Scientist report shows that researchers have discovered that Skype continues to send data even when the connected users make pauses between spoken words.
A standard Skype call transmits two different types of data: 130-bit data packets when one of the users is speaking and 70-bit data packets when no one is talking.
The researchers have developed a technology called SkypeHide that would allow someone to use the 70-bit data to transmit encrypted messages, with the secret information available only to those using the same system.
SkypeHide supports regular text messages, voice and video data at a rate of 1 KB per second though an active Skype call.
Of course, the system isn’t yet publicly available, but the researches will show it in action in Montpellier, France in June.
