The unauthorized surveillance and recording of VoIP calls has been discussed time and time again, but what happens when the surveillance of your call is being done at the endpoint by one of the participating parties? What if the surveillance was being done to analyze one of the caller’s stress levels and detect them lying, in real-time?
Apparently, Skype is set to provide a new feature application to it’s customers, the KishKish Lie Detector, which analyzes audio stream data in real-time, supposedly indicating the stress level of the person it’s analyzing. This makes me wonder, what if both parties are analyzing each other? Could mutual suspicions cause an escalating stress readout as each party gets more and more nervous by the indicated stress levels of the other party?
From the KishKish Lie Dectector website:
Voice Stress Analysis (VSA) is a type of lie detector which measures stress in a person’s voice. The use of Voice Stress Analysis (VSA) as a lie detector became popular in the late 1970s and 80s. In the 90s the first Computerized VSA (CVSA) systems came to out to the market. The CVSAT is now the truth verification device of choice in the law enforcement community as the number of law enforcement agencies utilizing the CVSAT continues to grow dramatically, proving the viability of the system for twenty-first century crime detection. The CVSAT is also being utilized by the US Military in the global war on terrorism.
Now KishKish Lie detector offers you a tool to detect the stress level of the person you communicate with over Skype. With the use of KishKish Lie detector you can monitor in real-time the stress level of the person you talked with. This allows you to gage the level of stress and modify your questions in real time. You could also use our KishKish SAM VSA that allows you to record the call and analyze the stress level off-line.
Did I miss the part where law enforcement and Dept. of Homeland Security began interrogating people via Skype? Perhaps the call recording feature could be used by responsible and patriotic citizens when fear-mongered into believing that they could be talking to potential terrorists AT ANY GIVEN MOMENT. Or perhaps I’m giving this way too much thought and people are generally just distrustful of each other and want the data points to back up that gut feeling.
