Browser fingerprinting is a technique used by advertisers and other companies to track individuals across the web.
It involves collecting information about a person’s web browser, such as the version, plugins, and other details, and using that information to create a unique “fingerprint” for each individual.
This fingerprint can then be used to target advertising and other content to that person across the web.
Browser fingerprinting is controversial because it can be used to track individuals without their knowledge or consent, and it raises concerns about privacy and online security.
It is also difficult to detect because the information collected is often not personally identifiable.
