Identification

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.

​As more and more products are manufactured via 3D printing, the potential for 3D-printed counterfeit versions rises accordingly. With that in mind, scientists have devised a method of ensuring that a printed item is the real thing, by building an "exploded" QR code into it.

Don't like the idea of a stranger finding out who you are, based on a photo? Thanks to the facial recognition systems used by social media sites, it's becoming increasingly possible. Scientists decided to do something about it, by turning a couple of AI systems against one another.

​Have you ever said of a person, "You can see it in the way they walk"? Well, if it was their identity that you were referring to, then you were right. To that end, scientists have now created an artificial intelligence-based system that identifies people via their footsteps.
