PersonaGuard is a decentralized, end-to-end encrypted platform that empowers individuals and small businesses to truly own and control their digital data. It provides a secure “personal data vault” where users can store sensitive information (documents, photos, health records, financial data) and selectively grant access to third parties without relinquishing ownership or relying on centralized servers. The platform leverages a combination of local encryption, distributed ledger technology for access control, and peer-to-peer synchronization for robust, self-sovereign data management, minimizing risks associated with data breaches and unwanted telemetry.
