The fight against spam. What is a captcha and what types of captchas exist?


In today's digital world, spam is a constant threat to web resources. It clogs inboxes, comments on websites, and can lead to various types of scams. In this article, we will explore what a captcha is and what solutions the company Sbitsoft offers to combat spam.

1. Captcha: protection against automated attacks

1.1. Captcha definition

Captcha is a technology designed to distinguish between a human and a computer program (bot). She represents a test or task that is easy for a human to solve but difficult or impossible for a computer to complete.  The goal is to prevent automated attacks and protect resources from unwanted influence.
