Identification

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.

​There's a relatively new way of determining what types of animals are present in an area – check the environment for their cast-off DNA, known as environmental DNA (eDNA). Next month, scientists will be using the technique in an effort to prove or disprove the existence of the Loch Ness monster.

​When it comes to determining a person's eye, hair and skin color based on a DNA sample, scientists typically need to compare that evidence sample to an existing reference sample. That's reportedly no longer the case, however, if they're using the new HIrisPlex-S DNA test system.

​Poachers typically hunt at night, which is why drone-mounted infrared cameras are being used to spot them. The problem is, it can be difficult to tell humans from animals in the videos. Scientists from USC are making the job easier, using artificial intelligence.

Smartphones are everywhere these days, packed with apps designed to make everyday life plain easier. Finland's Trafi is looking to tap into this ubiquitous nature so that drivers no longer need to carry a plastic driving permit, instead using a digital version accessed from within an app.
