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
7/8/2025
The potential of AI is limitless, but to truly unlock its possibilities, user inputs that power personalized experiences are key for those who want to get the most out of their AI tools. When AI understands you — your preferences, and your routines — it can deliver a mobile experience that feels like a natural extension of your everyday life.
Intuitive, context-aware Galaxy AI1 features bring personalized experiences to life, transforming your smartphone from a tool to a smart companion that offers suggestions designed to make you more productive, creative, and connected.
To deliver a personalized experience, your device needs access to certain personal data. It allows AI to understand you and tailor its responses in ways that can make your life more seamless. To protect your personal data in this era of AI, Samsung is constantly innovating to enhance data protection on your device.
Personalization Made Possible with Personal Data Engine
Samsung’s Personal Data Engine2 (PDE) is a key component of realizing these highly personalized experiences safely. First introduced with the Galaxy S25 series, the PDE is the powerhouse behind some of Galaxy’s most life-changing AI experiences yet. It learns from your patterns and preferences, creating a personalized experience tailored to you.
Whether it’s Now Brief3 guiding you through your day with curated updates, or simply finding that one perfect photo in your Gallery4 by describing it in natural language, Galaxy AI makes AI-powered actions feel seamless. And because the PDE processes many important pieces of data safely on-device, you get all the benefits of deeply customized AI — without compromising on privacy.
Powerful Advancements with Knox Enhanced Encrypted Protection
To deliver these personalized Galaxy AI experiences safely, Samsung has developed Knox Enhanced Encrypted Protection (KEEP) — a powerful new layer of on-device security that protects your sensitive data, without interrupting your experience. First developed for the Personal Data Engine, KEEP now also safeguards other Galaxy AI features including Smart Suggestions, Now Brief, Samsung Moments, and more to give each supported app its own secure environment.
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,5 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, offering added peace of mind. But as AI features like the Personal Data Engine start handling more sensitive tasks in real time, there’s a growing need for security that’s just as strong but more connected to your everyday experience.
