Voter Registration Guinea

  • 5 million voters
  • 2 databases (data scattered between 2 databases)
  • Single purpose voter cards
  • Fingerprints only


  • 7 million voters
  • 1 database (After migration, we consolidated all the data into 1 DB)
  • Voter card can be used as an ID
  • Fingerprint and face


In many countries, eligible voters do not often have a reliable ID. To prevent election fraud, a biometric registry is necessary to make sure that each registered person gets exactly one vote. The challenge is to collect data in the field and clean it from duplicates and ineligible voters like minors or deceased.

Once we had a clean voters registry, we needed to design, produce and supply voters with voter cards.

Innovatrics deployed multimodal (finger + face) ABIS and also provided the hardware. It also developed and installed software for field stations that were used to collect data and trained the supervisors of the process. The solution has been explicitly designed to collect high-quality biometric samples without compromising user experience.

After ABIS deployment, we migrated old records from previous elections. After enrolling new voters, we consolidated all data and ran deduplication to eliminate duplicates. Using our powerful face recognition and AI-driven age estimation, we were able to identify and eliminate minors.

Innovatrics delivered the biometric registry in record time. It also devised a secure process to collect data from the field stations even without reliable high-speed internet connection, ensuring the data is complete. The elections adhered to international standards according to independent observers.

  • 2 million

    Increase of eligible voters

  • Proof of identity

    Voters registry was used to generate unique IDs which can be used as a proof of identity

  • Face recognition modality added

    To increase accuracy when applying one person, one vote principle

  • Electoral standards have been completely observed

    The International Election Observation Mission has affirmed that international electoral standards have been completely observed in the recently concluded Guinea elections

The power of
efficient biometric algorithm

Security as a priority

The system was designed to prevent multiple voting and the process for gathering data guaranteed that no data has been lost in transfer.

International challenge

The elections have been closely monitored by international observers, so the system had to be accurate enough to weed out duplicates.

Clear voter registry

After all the data had been collected in the field, the voters registry was cleaned from duplicates and ineligible voters. Thanks to accurate algorithms and the world’s fastest ABIS, we deduplicated the database of 7 million voters in one week. Our advanced age estimation algorithm was then used to eliminate minors from the list.

Basis for future applications

With such a complete biometric registry of the adult population, Guinea can opt to provide other biometric services such as checking identity when providing social aid or financial services.

“CENI confirms the quality presence of Innovatrics by its side in the electoral process and would like to hereby reaffirm its gratitude and that of Guinea. “
