Google's AI system will now help you detect and block online scams

As online scams become more frequent and complex, Google has expanded its use of artificial intelligence (AI) to detect and block fraudulent content across Search, Chrome, Android, and regional programs. The company outlined its latest AI scam detection efforts in a recent official blog post.

These updates reflect the growing role of AI in protecting users from phishing schemes, impersonation attempts, and tech support fraud, which have been rising globally.

AI enhances Google Search fraud detection

Google’s AI systems now block hundreds of millions of scam-related webpages from appearing in Search results every day. According to the company, this represents a 20-fold increase in detection compared to previous years.

These AI models are trained to identify patterns used by scammers—such as misleading content, impersonation, and fake business listings.

This update supports Google’s broader strategy of reducing the visibility of deceptive websites and improving online scam protection for users worldwide.

Chrome uses on-device AI to spot scams

The Chrome browser has incorporated on-device AI, including the Gemini Nano model, to identify scam-like behaviour in real-time. This includes pop-up notifications that mimic system alerts or prompt users to install malware.

These scam warnings are processed locally on users’ devices, and are designed to flag attempts to gain unauthorised access or trick users into paying for fake services. Google says the system aims to reduce reliance on cloud data while enhancing browser-level fraud prevention.

AI tools in Android messages and calls

Google is also applying AI to monitor scam patterns in Android’s Phone and Messages apps. The system detects suspicious behaviour, such as requests for personal information or payment links from unknown numbers, and issues warning alerts to users.

This scam detection operates on-device and does not store or transmit message content to external servers, according to Google. The feature builds on ongoing efforts to reduce financial fraud via SMS and unsolicited calls.

DigiKavach: A regional program in India

In India, Google launched DigiKavach, a program aimed at identifying and intercepting online financial scams before they reach users. The initiative is being developed in collaboration with local partners including the Fintech Association for Consumer Empowerment and the CyberPeace Foundation.

This regional project combines early threat detection, AI surveillance tools, and public awareness campaigns to improve scam resilience at scale.
