Your Privacy, Secured: Inside the Tech Powering Safe, Personalized Galaxy AI Experiences

The Personal Data Engine and Knox Enhanced Encrypted Protection analyze and secure data to redefine AI security

The potential of AI is limitless, but to truly unlock the full potential of what it can do, user inputs that power personalized experiences are critical. AI needs to understand you — your preferences and your routines — to deliver a mobile experience that feels like a natural extension of your everyday life.

Intuitive, context-aware Galaxy AI features bring these personalized experiences to life, transforming your smartphone from a tool to a smart companion that anticipates your needs and offers suggestions designed to make your life more productive, creative and connected.

To deliver a fully personalized experience, your device naturally needs access to certain data. This is what allows AI to understand you and tailor its responses in ways that are genuinely helpful and suited to your lifestyle. To help keep your personal data  safeguarded in this era of AI, we’re constantly innovating data protection on your device.

Personalization Made Possible with the Personal Data Engine

Samsung Electronics’ Personal Data Engine (PDE)a key component of safely delivering these highly personal experiences. First introduced with the Galaxy S25 series, the PDE is the powerhouse behind some of Galaxy’s most intuitive AI experiences yet. It works silently behind the scenes to learn from your habits and preferences, resulting in a truly personalized, unique experience.

Whether it’s Now Brief guiding you through your day with curated updates or simply finding that one perfect photo in your Gallery with natural language input, Galaxy AI makes every AI-powered action feel seamless. And because the PDE safely processes your data on-device, you can enjoy all the benefits of deeply customized AI — without compromising privacy.

Powerful Advancements with Knox Enhanced Encrypted Protection

To further strengthen the security of Galaxy AI experiences, Samsung developed Knox Enhanced Encrypted Protection (KEEP)[3] — a powerful new layer of on-device security that protects your most sensitive data without interrupting your experience. First developed for the PDE, KEEP now also safeguards other Galaxy AI features like Smart Suggestions, Now Brief and more, running quietly in the background to ensure that each supported app is kept secure. Imagine turning part of the house into a private suite — still under the same roof, but with its own secure entrance that only you can use. It’s more private than a regular room, but not completely separate like the guesthouse. KEEP works the same way: it creates a secure, dedicated space for individual apps — like the PDE — so it can safely handle your data without sending it anywhere or getting in the way of how you use your phone.

Think of your phone like a house. Each app has its own room — separate, but all under the same roof. Then there’s Secure Folder,[4] which works like a fully detached guesthouse with its own key, set apart from the main home. It’s great for keeping certain things extra private, especially when you want complete isolation from the rest of your device.

As our mobile experiences become more intelligent, KEEP helps keep  your most personal data stays safe by design. Together with tools like Secure Folder, it reinforces Samsung’s multi-layered approach to data protection — giving both users and services the right type of security for different privacy needs.

With Galaxy AI becoming more personal, features like the Personal Data Engine and Knox Enhanced Encrypted Protection are setting a new standard for Samsung mobile intelligence — where personalization and privacy go hand in hand. As these experiences grow smarter and more attuned to your needs, you can rest assured that your most sensitive information will stay safe on your device, exactly where it belongs.
