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 ensure your personal data is safeguarded in this era of AI, we’re constantly innovating data protection on your device, so that nothing falls into the wrong hands.

Personalization Made Possible With the Personal Data Engine

Samsung Electronics’ Personal Data Engine (PDE)¹ is 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 life-changing 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 Brief² 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, Samsung Moments and more, running quietly in the background to ensure that each supported app is kept secure.

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. But as AI features like the PDE start handling more sensitive tasks in real time, there’s a growing need for security that’s just as strong, yet more connected to your everyday experience.

That’s where KEEP comes in. 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.

As our mobile experiences become more intelligent, KEEP ensures 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 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.

¹ The Personal Data Engine functions when the Personal Data Intelligence menu is on. Analyzed data will be deleted once the Personal Data Intelligence menu is turned off.
² Now Brief feature requires a Samsung Account login. Service availability may vary by country, language, device model and apps. Some features may require a network connection.
³ Available on Galaxy smartphones and tablets with One UI 8 or later.
⁴ Secure Folder offers users a separate and protected area of their phone or tablet to store sensitive apps and data. It allows users to set up separate profiles which can duplicate your apps. Users can customize the Secure Folder app and set up their own lock type, including PIN, pattern, password and fingerprint. For enhanced security, Secure Folder users are also provided with an option to hide and encrypt the Secure Folder, which helps keep data safe from advanced cybersecurity threats. While hidden, the apps will stop working to keep your data safe. Once the Secure Folder is opened again, the encryption will be deactivated, and the apps will resume normal operation.

Next-Generation Mobile Security for AI Personalization

Samsung is introducing Knox Enhanced Encrypted Protection (KEEP),¹ a new architecture designed to safeguard the next generation of personalized, AI-powered features, as its latest innovation in mobile security. KEEP creates encrypted, app-specific storage environments within the device’s secure storage area, ensuring that each app can access only its own sensitive information and nothing more.

Supporting Galaxy’s Personal Data Engine (PDE),² KEEP helps secure a user’s deeply personal insights — such as routines and preferences — that enable features like Now Brief and Smart Gallery search. These insights stay entirely on-device, protected by KEEP and further secured by Knox Vault, Samsung’s tamper-resistant hardware security environment. The result is a seamless foundation for Galaxy AI that delivers personalized intelligence while keeping data tightly contained and under the user’s control.

KEEP’s system-level structure allows it to scale across Galaxy AI innovations. In addition to PDE, it now protects Now Brief, Smart Suggestions and other on-device features that rely on user-specific inputs — enabling more advanced AI experiences without compromising privacy. With KEEP, Samsung is redefining how mobile devices safeguard data in the background to elevate privacy from a setting to an embedded design principle.

Smarter, More Connected Threat Response With Knox Matrix

As AI becomes more integrated across the ecosystem, Samsung is advancing protections that offer not just stronger security, but greater transparency and control for users, with Knox Matrix leading the way. Through One UI 8, Samsung is evolving Knox Matrix to deliver more proactive and user-friendly protection for connected Galaxy devices. When a device is flagged for serious risk — such as system manipulation or identity forgery — it is designed to automatically sign out of the Samsung Account, cutting off access to cloud-connected services to prevent threats from spreading.³

Users are notified across their connected Galaxy devices and guided to the ‘Security status of your devices’ page, where they can review the issue and take action. Even devices without the latest security status updates trigger a yellow-level warning, helping users respond before vulnerabilities grow.

Together, these updates make Samsung Galaxy’s ecosystem-level protection more dynamic, intuitive and visible, empowering users to maintain trust across all their devices with more confidence and clarity.

Secure Wi-Fi Strengthened With Quantum-Resistant Encryption

In continuation of its commitment to quantum-safe security, Samsung is bringing post-quantum cryptography to Secure Wi-Fi,⁴ extending the trusted approach first introduced on the Galaxy S25 series through Post-Quantum Enhanced Data Protection (EDP). Secure Wi-Fi is now being upgraded with a new cryptographic framework⁵ designed to strengthen network protection against emerging threats, particularly those anticipated in the era of quantum computing. This enhancement secures the key exchange process at the core of encrypted connections, helping ensure robust privacy even over public networks.

Quantum computing, once fully realized, could undermine many of today’s data protection methods. By integrating post-quantum cryptography, Secure Wi-Fi is built to withstand future attacks that capture encrypted data with the intent to break it once quantum technology matures — a tactic known as “harvest now, decrypt later.” This upgrade fortifies the secure tunnel between Galaxy devices and Samsung servers, reinforcing the integrity of data transmissions in high-risk environments like public Wi-Fi.

In addition to this future-ready foundation, Secure Wi-Fi offers a suite of advanced privacy features:

• Auto Protect: Automatically activates in public places like cafés, airports or hotels, securing Wi-Fi connections without requiring user action.
• Enhanced Privacy Protection (EPP): Encrypts internet traffic and routes it through multiple layers, combining packet encryption and relay to anonymize device information and help prevent tracking.
• Protection Activity: Provides visibility into protection history by showing which apps and networks were secured and how much data was encrypted over time.

A Trusted Platform With Built-In Safeguards

In addition to its latest innovations, Samsung continues to strengthen the core protections that underpin the Galaxy experience. These features reflect a multi-layered security approach that protects across hardware and software, while giving users greater visibility and control:

• Knox Vault secures sensitive credentials such as passwords, PINs and biometrics in a physically isolated environment, helping to keep them protected even if the main operating system is compromised.
• Auto Blocker helps provide defense by default, blocking unauthorized app installs, restricting command-based attacks and mitigating risks from potential zero-click threats.
• Advanced Intelligence Settings gives users the option to turn off online data processing for AI features, so personal information can stay on-device, fully under their control.
• Enhanced Theft Protection helps protect personal data even in high-risk situations such as robbery, using safeguards like Identity Check and Security Delay to prevent unauthorized access.

This latest set of updates reinforces Samsung’s long-standing commitment to mobile security that evolves with innovation. It strengthens on-device privacy for personalized AI with KEEP, expands transparency and user control through Knox Matrix, and introduces quantum-resistant protection to Secure Wi-Fi for a more future-ready Galaxy experience. As new security challenges emerge, Samsung remains focused on delivering safeguards that are built in, always on and ready for what’s next.
