Your Privacy, Secured: How Knox Vault Protects You in the Era of AI

The Galaxy advantage in privacy-first, AI-powered experiences

Galaxy AI is built to understand what you need, whether that’s suggesting a change in your routine or pulling up just the right information at the right time.

This level of personalization can be incredibly helpful, but the more your phone knows, the more there is to protect. So, what’s keeping all that personal data secure?

Samsung believes there is no privacy without strong security. That’s why every Galaxy device is protected from the chip up by a multi-layered approach, which includes on-device personalization, user-controlled cloud processing, and ecosystem-wide protection through the Samsung Knox Matrix.

At the core of this system is Samsung Knox Vault, the company’s hardware-based solution for safeguarding your most sensitive information.

Secured at the Hardware Level

Knox Vault is a hardware-level security solution that creates a physical barrier between your private information and everything else. It works like a locked room inside your phone, with its own processor and memory to encrypt sensitive data, with Knox Vault securing the keys. It pairs a secure processor with dedicated memory, isolating your passwords, PINs, biometrics, as well as financial information and cryptographic keys. You don’t need to activate or manage it, as it’s always on, working silently in the background, protecting your data while you get on with your day.

Knox Vault helps mitigate security concerns by safely storing personal information in a secure, hardware-isolated environment designed to help block both physical tampering and remote attacks, meaning your data can’t be accessed without approval.

Personalized AI, Protected at the Core

Knox Vault not only provides protection for today’s threats, it also helps maintain your privacy as mobile experiences continue to evolve.

As Galaxy AI becomes more useful, it also becomes more personal, learning how you use your device and adapting to your needs. And because these highly tailored AI experiences rely on sensitive data, Knox Vault plays a crucial role in keeping that information private.

Galaxy AI processes many tasks directly on-device where possible. For example, Audio Eraser¹, removes background noise from videos or voice recordings without the need for any cloud-based processing — so your personal information stays private. Call Transcript² operates in the same way, keeping your calls organized on-device.

Knox Vault helps keep your data protected, confidential, and secure. Building on its role in Galaxy AI as our foundation for security and privacy, Knox Vault will expand across Samsung’s growing AI ecosystem as AI becomes more deeply integrated into the user experience.
