Identification

It sometimes seems that as soon as another form of biometric ID authentication is developed, someone devises a way of fooling it. According to its creators, however, a new 3D finger vein-scanning system cannot be duped.

It's important to track the whereabouts of endangered black rhinos, but doing so in the wilds of Namibia can be difficult – particularly if you don't want to tag the animals. That's where a new footprint identification system is made to come in.

If you saw a finch once, chances are you'd have great difficulty picking it out from a group of finches later on. A new AI-based system can do just that, though, potentially making life much easier for both biologists and the birds that they study.

If you were studying the diet of ancient humans, it certainly wouldn't help if you got their preserved feces confused with those of their dogs. A new analytical system known as coproID is designed to keep that from happening.

Finding a person's fingerprints at a crime scene isn't always enough to convict them, as they can claim that those prints were left before the crime took place. That may be about to change, as scientists have devised a method of dating fingerprints.

Might it be possible that someday, an official might get you to dance around in order to confirm that you're really you? Perhaps not, but nonetheless, a study has determined that people's identities can be matched to their unique style of dancing.

As is the case with items that are manufactured in more traditional manners, it's certainly possible for 3D-printed products to be counterfeited. A new system could help identify such bogus goods, by printing a unique code right into objects.

Spanish scientists have developed a new verification system, which is said to be completely accurate at determining an egg's classification.

Utilizing a new technique, ordinary wall-penetrating Wi-Fi signals could reportedly now be used to identify a person within a house.

Scientists have designed a system that allows earbuds to help verify smartphone users' identities.

​Amazonian lakes and rivers don't always have the clearest of water, so how do biologists know if piranhas are present? They can always try fishing for the things, although according to new research, listening for their "barks" may be a better way to go.

So-called "ghost" fishing nets are awful things. Lost or forgotten during commercial fishing operations, they can drift in the ocean for years, indiscriminately catching marine life as they do. A newly-invented tag, however, may help keep that from happening.
