To understand the effects of continuous computerized surveillance on individuals, a Finnish research group instrumented ten Finnish households with video cameras, microphones, and logging software for personal computers, wireless networks, smartphones, TVs, and DVDs. The twelve participants filled monthly questionnaires to report on stress levels and were interviewed at six and twelve months. The study was carried out by Helsinki Institute for Information Technology HIIT, a joint research institute of Aalto University and the University of Helsinki, Finland.
The results expose a range of negative changes in experience and behavior. To all except one participant, the surveillance system proved to be a cause of annoyance, concern, anxiety, and even anger. However, surveillance did not cause mental health issues comparable in severity to depression or alcoholism, when measured with a standardized scale. Nevertheless, one household dropped out of the study at six months, citing that the breach of privacy and anonymity had grown unbearable.
The surveillees' privacy concerns plateaued after about three months, as the surveillees got more used to surveillance. The researchers attribute this to behavioral regulation of privacy. Almost all subjects exhibited changes in behavior to control what the system perceives. Some hid their activities in the home from the sensors, while some transferred them to places outside the home. Dr. Antti Oulasvirta explains: - Although almost all were capable of adapting their daily practices to maintain privacy intrusion at a level they could tolerate, the required changes made the home fragile. Any unpredicted social event would bring the new practices to the fore and question them, and at times prevent them from taking place.
The researchers were surprised that computer logging was as disturbing as camera-based surveillance. On the one hand, logging the computer was experienced negatively because it breaches the anonymity of conversations. - The importance of anonymity in computer use is symptomatic of the fact that a large proportion of our social activities today are mediated by computers, Oulasvirta says.
