- The site says each photo’s SHA-256 fingerprint is calculated on-device, signed with a secure-hardware key, and recorded on Soneium.
Field notes
The site says the image fingerprint is calculated on the phone and signed with a key held in secure hardware; it also describes checks intended to confirm that a submission came from an authentic app and device. It limits publicly disclosed location to an approximate five-kilometre area and says photos are not saved to the phone’s album. These are descriptions of the proposed system; the apps and prompt program are still forthcoming.
