Captchas and Other Security Measures

In web scraping, websites might implement various security measures to prevent automated access, using mechanisms like Captchas, IP blocking, or rate limiting. These security measures can make scraping more challenging. In this lesson, we'll explore strategies to handle captchas and other security measures when performing web scraping using Puppeteer.

Common security measures

In this section, let’s discuss a few standard security measures used widely today to block scraping data by automated scripts or bots and how to tackle them. These mechanisms will be improved/changed in the future, and web scrapping must also be improved to address those challenges.

Captchas

This is a sample captcha challenge to verify that the user is human. Captchas can take various forms, such as text-based challenges, image recognition tasks, puzzle solving, or selecting specific objects from a group. They typically require users to solve visual puzzles, select specific images, or enter text from distorted images.
