Decimen enables air-gapped optical file transfers
Decimen is an open-source browser tool for air-gapped file transfer between devices using fast-flashing QR code streams and camera decoding. By leveraging fountain coding to handle dropped frames, it enables resilient data transmission without Wi-Fi, Bluetooth, or native app installation.
Decimen offers an exceptionally practical and zero-trust approach to transferring small, sensitive files across strictly isolated systems without introducing network attack vectors.
* **Air-gapped security:** Bypasses wireless network protocols entirely, eliminating attack surfaces associated with Wi-Fi, Bluetooth, and cellular stacks.
* **Fountain coding resilience:** Frame-independent decoding guarantees full file reconstruction even with dropped frames, removing the need for a bi-directional communications link.
* **Zero-friction deployment:** Operates completely within standard web browsers across mobile and desktop devices without app installation or hardware configuration.
