CAPTCHAs: The Cybersecurity Shield in the Bot Battle
CAPTCHAs—Completely Automated Public Turing tests to tell Computers and Humans Apart—serve as a protective barrier against automated bot attacks on websites and mobile apps. These tests come in various forms, such as text-based, image-based, audio-based, and behavior-based challenges, and are crucial for enhancing cybersecurity and user experience.
Dayton Dayton (US), Aug 3 (The Conversation) - CAPTCHAs, those ubiquitous challenges encountered during website logins, are vital for distinguishing humans from bots. They protect websites and mobile apps from automated bot attacks, which can drain computing resources, post spam, collect data, and perform unauthorized actions.
These tests, known as Completely Automated Public Turing tests to tell Computers and Humans Apart, are a frontline defense in cybersecurity. As a computer scientist, I view CAPTCHAs as effective short-term measures against bot attacks, spam messages, and fraudulent user authentications.
Websites use various CAPTCHA types, including text-based, image-based, audio-based, and behavior-based, to verify human presence. Despite advancements in AI making some CAPTCHA forms less effective, the continuous evolution of CAPTCHA technologies aims to stay ahead in the cybersecurity battle. (The Conversation) AMS
