Could RFID and satellites help fight kidnappers?

Scientific American Blog: "The use of microchips to track people (such as those embedded in hospital wristbands) and products (those uncomfortable tags on clothing that have to be cut off prior to wearing) has come under fire from civil rights groups who claim that big corporations are using this technology as a tool for spying. But what about when these tags are embedded in people themselves, rather than the things they wear?"

"That's what Mexican security firm Xega SA, which sells technology for tracking people, wants to do, particularly in cases when people are held for ransom. For about $3,700, the company will implant a chip the size of a grain of rice (it costs another $1,800 per year for monitoring), reports the Telegraph. Although it is unclear where the chip is likely to be implanted in a person's body its customers carry with them a panic button that can be pressed if a person feels he or she is in danger. A transmitter then sends signals via satellite to pinpoint the location of a person in distress, reports Reuters.

How RFID Tags Could Be Used to Track Unsuspecting People

Scientific American. Radio-frequency identi­fication (RFID) tags are embedded in a growing number of personal items and identity documents.Because the tags were designed to be powerful tracking devices and they typically incorporate little security, people wearing or carrying them are vulnerable to surreptitious surveillance and profiling..."

"If you live in a state bordering Canada or Mexico, you may soon be given an opportunity to carry a very high tech item: a remotely readable driver’s license. Designed to identify U.S. citizens as they approach the nation’s borders, the cards are being promoted by the Department of Homeland Security as a way to save time and simplify border crossings. But if you care about your safety and privacy as much as convenience, you might want to think twice before signing up."

RFID--A Key to Automating Everything: Scientific American

"Thirteen years ago, in an article for Scientific American, the late Mark Weiser, then my colleague at Xerox PARC, outlined his bold vision of “ubiquitous computing”: small computers would be embedded in everyday objects all around us and, using wireless connections, would respond to our presence, desires and needs without being actively manipulated. This network of mobile and fixed devices would do things for us automatically and so invisibly that we would notice only their effects. Weiser called such systems “calm technology,” because they would make it easier for us to focus on our work and other activities, instead of demanding that we interact with and control them, as the typical PC does today.

"Today systems based on radio-frequency identification (RFID) technology are helping to move Weiser’s vision closer to reality. These systems consist of tags (small silicon chips that contain identifying data and sometimes other information) and of readers that automatically receive and decode that data.

'Frankenrobot' Has Biological Brain

Discovery News "Meet Gordon, probably the world's first robot to be controlled exclusively by living brain tissue.

"Stitched together from cultured rat neurons, Gordon's primitive grey matter was designed at the University of Reading by scientists who unveiled the neuron-powered machine on Wednesday.

"Their groundbreaking experiments explore the vanishing boundary between natural and artificial intelligence, and could shed light on the fundamental building blocks of memory and learning, one of the lead researchers said."

Human exoskeleton suit helps paralyzed people walk

"HAIFA, Israel (Reuters) - paralyzed for the past 20 years, former Israeli paratrooper Radi Kaiof now walks down the street with a dim mechanical hum.

"That is the sound of an electronic exoskeleton moving the 41-year-old's legs and propelling him forward -- with a proud expression on his face -- as passersby stare in surprise.

"The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company.

"Something of a mix between the exoskeleton of a crustacean and the suit worn by comic hero Iron Man, ReWalk helps paraplegics -- people paralyzed below the waist -- to stand, walk and climb stairs."

Are you a human scanner?

Scientific American "Those anti-bot security forms that slow you down when you're entering information just might serve a larger purpose. You're just about ready to buy a pair of tickets on Ticketmaster, but before you can take the next step, an annoying box with wavy letters and numbers shows up on your screen. You dutifully enter in what you see—and what a bot presumably can't—in the name of security."

"But what you may not know is that you also have helped archivists decipher distorted characters in old books and newspapers so that they can be posted on the Web."
