Google Enhances Chrome Security with AI
Google is making its Chrome browser safer by adding a new AI security layer.
This layer, called 'User Alignment Critic,' is like a guard that checks what another AI in the browser does.
It makes sure the AI doesn't do anything bad, like stealing information or making unauthorized transactions.
Google is also adding other safety features, like limiting where the AI can go on the internet and asking users to confirm important actions.
They are even offering money to people who find security problems in this new system.
This is all to protect users from hackers who might try to trick the AI into doing harmful things.
Google announced a new AI security layer in Chrome called 'User Alignment Critic' on November 8.
The layer is designed to vet actions of AI browser agents to prevent malicious activities.
Chrome will also include origin-isolation to restrict AI agent interactions with specific sites.
Google is offering up to $20,000 for finding breaches in the new security layer.
The upgrade aims to mitigate indirect prompt injection attacks, where hackers hide malicious instructions in web pages.
