Determining who is human on the Internet has always been tricky, with bots, crooks, and troublemakers finding ways to outsmart systems.
For decades, CAPTCHA has been the most popular defense tool, relying on simple puzzles to distinguish humans from machines.
“This isn’t a new problem; it’s an ongoing battle,” said Grant Ho, an assistant professor for computer science at the University of Chicago.
However, artificial intelligence (AI) is now rendering CAPTCHA obsolete, and researchers are rethinking verification systems, exploring ways to incorporate AI, behavioral biometrics, cryptographic proofs, and blockchain-based identities.
According to Grant Ho,
“It’s becoming increasingly difficult to differentiate humans and bots,”as AI rapidly redrawing the digital battle lines.
