In computer science, fingerprinting is a procedure that maps an arbitrarily large data item (such as a computer file) to a much shorter bit string, its fingerprint, that uniquely identifies the original data for all practical purposes just as human fingerprints uniquely entify people for practical purposes.[1]
How it works
Fingerprinting works by getting a data item and turning it into a much shorter bit string that uniquely identifies itself.
Why it is a problem
Fingerprinting can be used to identify individuals, flagging privacy concerns and letting companies do things like targeted advertising, selling personal data and more.
Examples
Some examples of fingerprinting include some types of cookies,
