Captchas

A CAPTCHA is a type of challenge-response test used in computing to determine whether or not the user is human. The name is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart".

CAPTCHAs are used to protect websites from spam and abuse by automated programs, known as bots. By requiring users to solve a CAPTCHA, a website can ensure that only humans are able to access its content.

Relation to GDPR

However, CAPTCHAs can also pose a privacy concern. When a CAPTCHA is solved, the website may collect information about the user, such as their IP address, browser type, and operating system. This information could be used to track users and target them with ads or other content.

For this reason, it's important to be aware of the privacy implications of CAPTCHAs before using them. If you're concerned about your privacy, you may want to avoid websites that use CAPTCHAs or take steps to protect your information, such as using a VPN.
