Samsung's new Galaxy AI shields user data in a hardware-secured Knox Vault, blending on-device and cloud AI while deleting input immediately to protect privacy.
As AI becomes central to smartphone functionality, Samsung's latest integration of Galaxy AI with its Knox Vault and post-quantum encryption assures users their personal data stays private. The approach avoids cloud-based retention of sensitive information, signaling a shift toward privacy-first mobile AI amid growing concerns over data misuse.
"The cloud AI will access your data only when it's necessary and your data is deleted shortly after your request is completed," said Jay Kim, Samsung's head of customer experience, in a statement. "This means you don't have to worry about your information being used to train AI models or for advertising. Our secure hybrid AI approach keeps your data private and secure while delivering a cutting-edge, personalized AI."
Galaxy S25 AI Privacy Features Arrive with One UI 7 and Knox Vault
Samsung built these privacy controls into One UI 7, debuting alongside the Galaxy S25 lineup in early 2025. The Galaxy's "Personal Data Engine" processes sensitive requests, such as finding images or summarizing agendas, entirely on-device. Sensitive data and decryption keys are stored in Knox Vault—a physically isolated, tamper-resistant secure enclave with its own processor and memory. For cloud-supported AI like Gemini-based generative edits, Samsung guarantees immediate deletion of user inputs once outputs are delivered.
This enhanced privacy architecture aims to build trust across industries—appealing particularly to enterprise and security-conscious consumers. By blending on-device convenience with encrypted cloud processing, Samsung offers tailored AI features (e.g., generative edits, translation, agenda summaries) without compromising data exposure. Social media and tech forums have responded positively, noting that the inclusion of a user-controlled "AI off switch" for cloud AI marks a significant advancement in mobile privacy.
Reddit user @heyitsai posted, "Samsung just did something shockingly sensible with the Galaxy S25—an AI off switch... that actually makes sense. You can disable cloud-based AI while keeping on-device AI running. That means you get privacy, faster local processing, and AI features that don't rely on some mystery server."
Samsung's official statement reiterates that no personal data from Galaxy AI is used to train third-party models or serve targeted ads. They highlight additional protections via Knox Matrix, post-quantum cryptography, Secure Boot, and a unified Security & Privacy Dashboard in One UI 7. The company also promises seven years of security updates, ensuring long-term protection.
By combining hardware-based isolation with instant data deletion, Samsung gives users more control over their personal information, aligning with the growing demand for privacy in daily AI use.
