Google Chrome has long prioritized user privacy and safety with features like Enhanced Safe Browsing, introduced in 2020. This feature utilizes real-time threat detection to protect users from malicious websites and files. Now, Google is enhancing this protection with the integration of its Gemini Nano AI, specifically designed to combat online scams targeting smartphone users.
Initially, this AI-powered scam detection will focus on deceptive tech security warnings often found on malicious webpages. These warnings often mimic legitimate security alerts, tricking users into taking harmful actions.
How Gemini Nano Works
Malicious websites employing fake security warnings often follow predictable patterns. Gemini Nano has been trained to recognize these patterns and identify the true intent behind such warnings. When a website exhibits suspicious behavior, the AI analyzes the warning and flags it to the Safe Browsing system.
If a webpage is flagged as potentially risky and exhibits signs of a scam, Chrome will display a notification alert to the user. This notification will include the website’s name and a warning message about its potentially harmful nature. Users can then choose to unsubscribe from the website’s notifications with a single tap, or whitelist the site if the alert was a false positive. Users also have the option to view the blocked web content.

This feature is initially rolling out to Android smartphones later this year. While specific hardware and software requirements haven’t been detailed, Google’s focus on Android stems from the fact that the majority of these malicious notifications target mobile devices. However, Google is exploring the possibility of extending this AI-powered protection to other platforms in the future.
The Importance of On-Device AI Protection
Tech support scams, which often involve fake alerts warning users of non-existent viruses, are a growing threat. These malicious websites often employ varied tactics, making it crucial to assess the threat from the user’s perspective. This is where Gemini Nano’s AI capabilities become invaluable.

Previously, Google relied on real-time matching against blocklisted content, supplemented by a small sample of shared browsing data for security analysis. Gemini Nano shifts the security scan to the device itself, offering significant advantages. Because malicious sites often have a short lifespan – averaging less than 10 minutes – on-device protection enables faster detection and blocking of new, previously unindexed threats. This approach allows Google to analyze threats in real-time, as they are presented to the user, significantly enhancing protection against evolving scam tactics.
Conclusion
With the introduction of Gemini Nano, Chrome for Android is taking a significant step forward in protecting users from online scams. This AI-powered, on-device approach offers faster, more effective protection against the ever-changing landscape of online threats. By analyzing suspicious website behavior and alerting users to potential scams, Gemini Nano empowers users to make informed decisions and stay safe online. While initially launching on Android, the potential for expansion to other platforms promises even broader protection against these evolving threats.
