Summary: 60
Sensors, Tags, and Security
Joshua R. Smith
Abstract
Sensors and Radio Frequency Identification (RFID) tags promise to create
environments that are safer, smarter, and more secure---benefiting persons
with disabilities, and everyone else. First I present several examples to
illustrate the promise of sensors and tags. Then I describe an obstacle
to realizing the vision---the high cost of tags---and a possible solution:
bifurcating future tags into one class that is less capable but far cheaper
than the tags of today, and another that is much more capable, though
expensive.
The Promise of Sensors and Tags
Giving our houses, cars, and other everyday environments the ability
to sense and identify every object, every person, and their respective
activities and histories would create enormous benefits, for persons with
disabilities, and everyone else. Every physical object would have a "digital
shadow," a set of electronic information that corresponds to the physical
object. This vision would enable everyday environments to become
smarter, safer, and more secure.
