SPACE SECURITY / CRYPTOGRAPHIC PRESENCE
GeoProof transforms geographic presence into independently verifiable digital evidence — binding time, satellite geometry, and cryptographic signals without asking a verifier to trust receiver-reported coordinates.
PRESENCE ZONE
THE GEOPROOF METHOD
From location positioning to provable physical presence.
A proof is created from evidence available only at a place and time, then verified independently against synchronized trusted state and satellite geometry.
01 / BROADCAST
Satellite-side nonce transmission
Satellites generate and broadcast unpredictable, time-sensitive cryptographic nonces under synchronized secure state.
02 / COLLECT
Physical reception of evidence
A receiver passively collects the broadcasts available from its physical location. It does not hold the secret seed or predict future nonces.
03 / VERIFY
Independent reconstruction
A verifier reconstructs expected evidence from trusted state, time, and satellite geometry — then determines whether the proof is consistent with presence.
IMPLEMENTATION PATH
A location-bound cryptographic primitive for high-assurance systems.
Location-bound access
Policy decisions conditioned on independently verifiable physical presence.
Geo-encryption
Cryptographic workflows tied to evidence that was physically available at an authorized place and time.
Critical infrastructure
Higher-confidence authorization for systems where place and time matter.
Secure autonomous systems
Evidence-aware workflows for autonomous and unmanned platforms.
Space and satellite security
Location-sensitive security primitives designed around satellite signal geometry.
Location-sensitive services
Exportable proofs that can travel between systems for independent verification.
Technology validation
USE-CASE BRIEFINGS
Proof of presence where consequential decisions happen.
These briefing concepts show how independently verifiable presence evidence can strengthen authorization, asset integrity, compliance, and location-dependent operations.
Location-bound authorization
Sensitive commands can require verifiable evidence that the operator and authorized receiver were physically present at an approved location and time.
Asset & shipment proof of presence
A cryptographically bound record can help stakeholders verify that an asset or shipment was present at required locations during critical stages of a journey.
Remote asset verification
High-value remote equipment can produce independently verifiable presence evidence alongside asset-bound integrity and tamper signals.
Geographic compliance
Operational policies can be checked against signed, time-sensitive evidence that a device was present inside an authorized geographic boundary.
Location-locked UAS missions
Mission capabilities can remain unavailable until physical reception conditions support an independently verifiable proof of presence inside the required region and time window.
