The Orb is equipped with a powerful computing unit able to run several neural networks concurrently in real-time. This enables it to validate a person’s humanness locally on the device without needing to process unencrypted images on the Orb backend.
Similarly, a person’s iris fragment (a mathematical representation of the iris texture) is generated locally on the Orb as well and compared against other iris fragment without decrypting them. Each iris fragment is split into multiple different secret fragments that are stored and encrypted across multiple secure databases (read more about AMPC).
Subsequently, all images and image derivatives are packaged, encrypted and signed by the Orb to ensure authenticity and security, then sent to the user’s phone through the Orb backend server (importantly the backend cannot decrypt the data). All images are then deleted from the Orb. More details on the iris fragment can be found in the technical implementation documentation of the Whitepaper.
