Election Infrastructure & IAM System
Electoral Commission of Ghana // 2023
38,000 field officers. One secure, offline-first identity fabric.
SENTINEL is the mission-critical Identity and Access Management platform underpinning Ghana's national election infrastructure. It manages multi-factor authentication for field officers, integrates with biometric voter verification hardware, and provides tamper-evident results aggregation — ensuring the integrity of the democratic process from the polling station to the national collation centre.
The EC required an access management system capable of handling 38,000 concurrent field officer authentications on election day, in facilities ranging from urban centres with fibre connectivity to remote rural polling stations with zero reliable internet access. Any system that required consistent connectivity was a non-starter.
We built an offline-first synchronisation architecture where every field device carries a cryptographically signed local state that can operate fully independently. Authentication credentials are pre-provisioned with time-bound validity, and all results submissions use a tamper-evident Merkle-tree logging structure that makes any retroactive modification structurally detectable on resync.
Successfully secured the 2024 general election infrastructure across all 38,000 field deployments. Zero security incidents. Offline sync integrity maintained at 100% — every device reconciled cleanly on reconnection. Declared by international election observers as a gold standard for digital election security in Africa.
"We had polling stations in areas where the nearest internet connection was 40 kilometres away. SENTINEL worked flawlessly. Every ballot was accounted for. This was a turning point for election administration in Ghana."
"As an independent observer, I have reviewed election technology deployments across 14 African nations. The offline-first architecture Axon implemented here is the most technically rigorous I have evaluated."
