Tamper-proof audit readiness

This patent describes a system for storing and protecting sensitive files across a distributed network (similar to a blockchain) in a way that keeps files private, verifiable, and under your control. Files are split into small encrypted pieces (component files) and a master key object that can be stored on different computers. The key innovation is that only the file owner can decrypt and reconstruct the file; not even Filot can do it. And every action (who accessed what, when, by whom) is recorded in an unchangeable ledger.

Regular encryption protects files while they're stored or moving, but the encryption key is often controlled by the service provider. With Filot's patented approach, your encryption keys stay with you. Files are also split into pieces distributed across multiple computers, so no single point of failure or compromise exposes your entire file. Even if someone breached Filot's servers, they'd find only encrypted file fragments without the key to unlock them. And the unchangeable audit trail means you can prove exactly what happened to your files without backdoor or hidden tampering.

No. Other secure file-sharing services exist and some are good. But this patent describes a specific architecture that combines distributed storage, zero-knowledge encryption, and tamper-proof audit trails in an integrated way that most competitors don't match. Some competitors use encryption, but not distributed architecture. Some have audit trails, but they're alterable. This patent covers the combination, and that combination is what makes Filot's approach to security and compliance unique.

Absolutely. The patent describes what's happening under the hood, but you don't need to understand it to use Filot. From your perspective, you send files, invite people to access them, and track what happens. Filot handles all the complex distribution, encryption, and verification automatically. The patent is proof that the technology behind those simple actions is architected for security and ownership in a way most competitors simply can't replicate.

Zero-knowledge storage means the service provider (Filot) stores your files but cannot read them or access the encryption keys. The patent describes how Filot encrypts files with your encryption key before they're ever sent to our servers. Your private key stays on your device. We literally cannot decrypt your files even if we wanted to. This is different from most cloud storage services, where the provider holds the keys and could theoretically access your files. With Filot's patented approach, we structurally cannot.
