Security and privacy have become greater concerns in the era of AI and interconnected device ecosystems. The new Galaxy S25 employs a wide range of security features and is Samsung's first phone series to introduce post-quantum cryptography against even the most dangerous quantum-based cyber attacks.
Thanks to the Snapdragon 8 Elite chip, the Galaxy S25 series is powerful enough to process most of its Galaxy AI features on the device without accessing or sending personal information to any servers.
Features like Now Brief rely on the Personal Data Engine to analyze data on-device and deliver personalized experiences. However, this personal data has to be stored safely on the Galaxy S25 and kept private.
For Galaxy S25 users, personalized AI data is securely locked behind Knox Vault, which now has a new future-proof security layer, i.e., post-quantum cryptography.
In essence, post-quantum cryptography, or PQC (via Wikipedia), consists of cryptographic algorithms that should be secure against cryptanalytic attacks performed by a quantum computer.

The Personal Data Engine gathers data for personalized AI experiences only from native Samsung apps and recognizes many languages and dialects, including but not limited to the following:
- Arabic, (Simplified) Chinese, Dutch, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Thai, Turkish, and Vietnamese.
Furthermore, the Personal Data Engine itself is customizable and only functions under the parameters set by users through the Personal Data Intelligence menu on the Galaxy S25. If this feature is turned off, all the analyzed user data is deleted instantaneously from Knox Vault.
Samsung also provides better security for Galaxy S25 users through a new Knox Matrix dashboard, additional Maximum Restriction settings, and enhanced Theft Protection.
