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 before you even ask, 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 Samsung Knox Matrix.

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

Secured at the Hardware Level
Most devices rely on software alone to guard sensitive data, but Galaxy devices go further.

Knox Vault is a hardware-level security solution that creates a physical barrier between your most private information and everything else. It works like a locked room inside your phone, with its own processor and memory. It pairs a secure processor with dedicated memory, isolating your passwords, PINs, biometrics, and cryptographic keys. These are the kinds of details you don’t want anyone else to access, and Knox Vault is built to make sure they stay private. You don’t need to activate or manage it, it’s always on, working silently in the background, keeping your data safe while you get on with your day.

This is particularly crucial in the age of AI as user concerns are expanding from traditional cybersecurity threats, like viruses and malware, to worries over leaking personal data, such as conversations with your AI assistant. And as AI becomes part of more everyday tasks, the types of data that need protection are also expanding.

For example, location service metadata from your most personal photos, not only details the resolution and file format, but could easily give away the exact location where the image was taken. In the era of AI, personal information like your home address, face clustering ID, person ID, pet type, scene type and more need to be encrypted and stored in a safe location. These things aren’t just files — they are deeply connected to your daily life.

Knox Vault helps mitigate these growing concerns by safely storing personal information in a secure, hardware-isolated environment designed to block both physical tampering and remote attacks, ensuring 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 ensures 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 this relies on deeply personal data, Knox Vault plays a crucial role in keeping that information private.

Features like Now brief provide useful summaries and suggestions based on your daily activity, while Modes and Routines¹ create auto-generated routines by adjusting settings in response to your habits. These tools and the highly tailored AI experiences they enable are guided by a map of personalized data — data that is encrypted, with Knox Vault securing the keys.

Galaxy AI also ensures privacy by processing tasks directly on-device where possible, keeping data in your hands and off online servers. For example, Audio Eraser,² removes background noise from videos or voice recordings without the need for any cloud-based processing — so your personal information stays private. Call Transcript³ and summary operates in the same way, keeping your calls organized while ensuring personal conversations stay private by remaining on-device.

Knox Vault ensures your data is protected, confidential, and secure. Building on its role in Galaxy AI as the trusted 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.

Knox Vault is more than a security feature, it’s Galaxy’s promise that no matter how advanced your devices become, or how much AI evolves, your privacy is secured.
