But first, let’s start by exploring what, exactly, browser fingerprinting is. Luckily, there are a few things you can do to wipe all of your fingerprints from the internet. Please include a postal address, daytime telephone number and email address. Browser fingerprinting is an incredibly accurate method of identifying unique browsers and tracking online activity.

Humpback whales also have unique markings on the underside of their tails. Zebras have distinct stripe arrangements and individual leopards and spotted dolphins have their own spot patterns. Individual cats and dogs, for example, have unique whisker patterns. Koalas have unique fingerprints just like humans, but many animals have what seems to be the equivalent of fingerprints. Samira Bendjedidin, Reading, Berkshire, UK This was reported in New Scientist back in 1996. Indeed, in 2002, police in Hampshire, UK, worked with a team from Marwell Zoo on a study of fingerprints from Sulawesi macaques with a view to identifying individuals to help prevent poaching.Ĭoncerns have even been expressed in Australia that there might be some unidentified fingerprints languishing on crime scene databases that were made by koalas, due to the similarity of patterns on their hands to those found in humans. It was sometimes difficult to distinguish those made by the residents from those left by the sticky digits of the visitors. In the heady days before lockdowns, in places such as Monkey World in Dorset, UK, you could observe finger marks on the glass partitions of enclosures. Their sensitive fingers may have evolved to allow them to identify the texture of their ideal meal. Koalas are notoriously fussy eaters, preferring to eat only eucalyptus leaves of a particular age. Fingerprints increase, the size of these vibrations about 100-fold. When we run our fingers over an object, this sets off tiny vibrations in the skin, which are detected by nerves.
Fingerprints are also thought to increase the sensitivity of touch, allowing us to discriminate finer details. Suggested benefits include improved grip and the prevention of blisters. The primary function of fingerprints still isn’t universally agreed on.
