A headline in the USA Today earlier this week screamed, “Hello, Big Brother: Digital Sensors Are Watching Us.” It opens with an all too typical techno-panic tone, replete with tales of impending doom:
Odds are you will be monitored today — many times over. Surveillance cameras at airports, subways, banks and other public venues are not the only devices tracking you. Inexpensive, ever-watchful digital sensors are now ubiquitous.They are in laptop webcams, video-game motion sensors, smartphone cameras, utility meters, passports and employee ID cards. Step out your front door and you could be captured in a high-resolution photograph taken from the air or street by Google or Microsoft, as they update their respective mapping services. Drive down a city thoroughfare, cross a toll bridge, or park at certain shopping malls and your license plate will be recorded and time-stamped. Several developments have converged to push the monitoring of human activity far beyond what George Orwell imagined. Low-cost digital cameras, motion sensors and biometric readers are proliferating just as the cost of storing digital data is decreasing. The result: the explosion of sensor data collection and storage.
Oh my God! Dust off you copies of the Unabomber Manifesto and run for your shack in the hills!
No, wait, don’t. Let’s instead step back, take a deep breath and think about this. As the article goes on to note, there will certainly be many benefits to our increasing “sensor society.” Advertising and retail activity will become more personalized and offer consumers more customized good and services. I wrote about that here at greater length in my essay on “Smart-Sign Technology: Retail Marketing Gets Sophisticated, But Will Regulation Kill It First?” More importantly, ubiquitous digital sensors and data collection/storage will also increase our knowledge of the world around us exponentially and do wonders for scientific, environmental, and medical research.
But that won’t soothe the fears of those who fear the loss of their privacy and the rise of a surveillance society in which our every move is watched or tracked. So, let’s talk about what those of you who feel that way want to do about it.
