The Electronic Nose Knows
The human nose contributes to everything from the experience of flavor to the association of scent with memory. Even more remarkable, a dog’s nose can be used to identify the faintest of smells thanks to a specialized portion of the canine brain that is 40 times larger than humans.
As technology has evolved, scientists are taking a closer look at this unique ability for scents to be used for identification.
Today, expertise in areas like DNA-based receptors and nano-manufacturing sensors are being applied to the “electronic nose,” a technology that has the potential to revolutionize fields like medicine and biometrics.
BIOMETRICS THEN AND NOW
Since ancient times, biometrics has used a range of human characteristics to establish a person’s identity – from handprints used as signatures in cave paintings to the modern-day practice of taking fingerprints.
But as society’s security needs have grown, so has the need for quicker, more reliable methods of identity confirmation that are vital to public safety. Security agencies like law enforcement rely on fast, accurate processing of information to identify and apprehend suspects before they can slip away – or commit another crime.
|Lockheed Martin is applying research to areas like the electronic nose in order to “sniff” a fingerprint and detect things like body odor, drugs or explosives that can be associated with the fingerprint. In addition, an imaging system can visualize latent prints on multiple surfaces in real time, without altering or touching the prints. This preserves any scents or DNA on the print and adds to the useful evidence.||
OTHER BIOMETRIC IDENTIFIERS
The most well-known technology associated with fingerprint identification technology has advanced dramatically in recent years, while other biometric identifiers have come into wider use.
