In addition to transmitting data, fiber optic cables can do this

The information sensed by fiber optic cables is considered "noise", and Eric Rodenbeck of Stamen Design in San Francisco recently realized that underground fiber optic cables can detect various activities on the ground, which can be used to track the movement of
people and cars.

With funding from London's V&A Museum, Steman Design extracted data from a 3-kilometer fiber optic cable beneath the Stanford University campus to visualize
its detections.
The interactive diagram shows the various vibration waves
generated by different activities on the ground.

Some companies are already taking advantage of this technology
.
They use fiber optic cables as sensors rather than information transmission tools
.
Rodenbeck said a company called Optasense began placing fiber optic cables around pipelines and other secure areas to detect activity
around those areas.

In addition to fiber optic cables, other infrastructure can also be used as sensors
.
Cell towers can be used to map the humidity of an area
.
This is because the communication process between mobile phones and cell towers is directly related
to air humidity.

In addition, the cable induction is also very accurate
.
It can even detect how many people are in the car, or the type of
vehicle.
Basically, this complex system is already in place, just waiting to be activated
.

There is no doubt that this technology will once again raise privacy concerns
.
It may be used to track and monitor
individuals.
"It's an amazing technology, but it's also scary," Rodenbeck says, "and it opens up a range of possibilities, both positive and negative
.
