Samsung Doubles Down on Privacy with KEEP, Knox Matrix, and Quantum-Safe Wi-Fi in One UI 8

As Samsung gears up for its Galaxy Unpacked event on July 9, all eyes are on the upcoming Galaxy Z Fold 7, Z Flip 7, and the new One UI 8. But before the big reveals, Samsung is already dropping major news – and it’s all about keeping your data locked down tighter than ever.

The tech giant has introduced KEEP – short for Knox Enhanced Encrypted Protection – a powerful new privacy layer embedded in One UI 8.

This isn’t just about locking files. KEEP isolates sensitive data like your app activity, voice transcripts, and AI interactions into secure, individual vaults. For example, if Samsung’s Call Assist transcribes a conversation, that data is kept in its own encrypted container, safe from prying eyes and other apps.

Powered by Galaxy’s Personal Data Engine (PDE), KEEP also shields tools like Smart Gallery Search and Now Brief, ensuring all that personal, AI-driven magic stays strictly on-device. Combined with the hardware-based Knox Vault, this forms a formidable barrier against unwanted data leaks.

Another major step forward is the revamped Knox Matrix system. If One UI 8 senses suspicious behavior – like attempts to spoof your identity or tamper with system settings – it can instantly log your device out of your Samsung account. Not just that, it’ll ping all your linked Galaxy devices and lead you to a new dashboard called “Security status of your devices,” giving you clarity and instructions to resolve issues. Even phones that aren’t fully updated can still give early warnings via a yellow alert signal.

And yes, Samsung is going quantum-proof with its Wi-Fi. The Secure Wi-Fi tool – already encrypting your browsing – now comes with post-quantum cryptography (first seen on the Galaxy S25 series). This future-ready encryption fends off ‘harvest now, decrypt later’ attacks, where hackers stash away your encrypted data hoping to crack it once quantum computers go mainstream.

This update strengthens how your Galaxy phone and Samsung servers exchange encryption keys – which is crucial for staying safe on public networks. While full-scale quantum attacks aren’t here yet, Samsung’s preemptive move is smart, and it shows they’re not waiting around for the next privacy disaster.

But there’s a small hitch – you only get 1,024MB of Secure Wi-Fi data monthly if you’re on Android 13+, and just 250MB for Android 12 or older. The protection is solid, but the cap might feel tight for regular users.

Additional tools include:

• Auto Protect that activates in public Wi-Fi zones like airports and cafés
• Enhanced Privacy Protection that anonymizes your data
• Protection Activity which gives a clear breakdown of what was encrypted

In an era where AI is embedded in nearly every app and data breaches keep making headlines, Samsung’s forward-thinking security approach is a welcome move. While flashy foldables might steal the spotlight, the under-the-hood privacy tech in One UI 8 could prove to be the true game changer.
