Next Gen Surveillance Is Fast Becoming Today’s Reality!

If terrorism becomes pandemic in Europe and America, emerging surveillance tools may be abused in even more bizarre ways. At the same time, the overhead burdens of a police state could impose crippling costs on a free-market economy. Witness the U.S. clampdown on foreign student visas, which could end up crimping a universities ability to do advanced research.

Industry experts disagree about when the most advanced tools to thwart terrorist acts will arrive on the market and whether they will even deliver what they promise. Sensors that can detect bombs, radiation, and toxins exist today, and will be far more sophisticated a decade from now. But strewing them across every city in America would cost untold billions of dollars. High-tech electronic eavesdropping on communications networks can be effective, but only if terrorists use telecom systems. But even with the latest improvements in spy cameras, biometric devices such as iris scans, bomb sniffers, and tracking software, it will be many years before they can pick a terrorist out of a crowd and stop him before he commits his terrorist acts. Sacrifices in society and in governments will be made as our society becomes a surveillance society. The debate will rage on for decades to come.

The Ultimate Universal Sensor, a small and cheap enough to scatter in public places, and smart enough to sniff out anything that comes its way, without being preprogrammed to find specific molecules. Nobody is close to reaching that goal yet, but Sandia National Laboratories has designed a lab-on-a-chip that detects a variety of both chemical and biological agents. It has skinny micro channels etched in its surface. When a gas or liquid moves through the tiny pipes, it collides with special material, and how much that slows the flow betrays the identity of the fluid. Sandia is now developing this technology to monitor the Contra Costa County (Calif.) water supply.

These systems may not be in place in time for the next attack in a Western country let alone in Egypt or Iraq but if terrorists hit the U.S. again, the authorities are bound to strike back. Among other things, today’s restraints on racial profiling are likely to crumble. Then what will we do? In the arms race against the terrorist suicide bombers, will surveillance technologies prove their worth?

Some governments have already used Electronic Monitoring to foil some terrorist plots, and portals that spot guns and explosives make airports safer. Unfortunately, many of the most powerful technologies are simply too new. It may take a decade or more before networks of biochemical sensors are ready to blanket a whole city. And it could take as long before camera systems can pick a known face terrorist or otherwise out of the crowds. For now, only a combination of electronic monitoring and human intelligence stands a chance of holding radicals at bay.

In the meantime, scientists who labor on surveillance prototypes are encouraged that their innovations can bring benefits in health care and food safety. Over time, people may get smarter about how to live with threats and make use of technology without undermining their most basic values. A country that sacrifices its citizens’ freedom in the fight to protect them is no hero.
