Nairobi Clears Millions of Ghost Images From Government Databases Weekly

Kenya's e-government infrastructure spent much of this week in emergency maintenance mode, as technicians across at least four national agencies worked to purge tens of thousands of duplicate scanned images that have accumulated inside public databases since the digitisation push began in earnest around 2019. The problem, long acknowledged in ICT circles along Ngong Road's technology corridor but rarely addressed at scale, finally triggered formal action after an internal audit flagged critical storage overruns at two flagship systems.

The timing is uncomfortable for the Ruto administration. With the IMF austerity programme squeezing recurrent budgets and the Gen Z tax revolt still fresh in public memory, any revelation that public money has been haemorrhaged on redundant data infrastructure carries real political sting. Cloud storage and on-premise server capacity are not cheap line items: industry benchmarks in East Africa typically price enterprise cloud storage at between KSh 4,500 and KSh 9,000 per terabyte per month, and bloated image libraries can push agencies well past their allocated gigabyte ceilings.

Where the Problem Showed Up

The Huduma Centre network, which operates busy walk-in service points at Anniversary Towers on University Way and the Teleposta Towers branch on Kenyatta Avenue, relies on a shared document management backbone that ingests scanned ID photos, land title images, and birth certificate scans daily. By Thursday, technicians working under the State Department for ICT had reportedly identified duplicate image sets running into the hundreds of thousands across the national civil registration module, though the department had not published a final figure by press time.

The eCitizen platform, which processed more than 65 million service requests in the 2024-2025 financial year according to figures published by the government's digital economy blueprint, stores profile photographs and supporting document scans for every registered user. When users re-register or resubmit applications, a common occurrence after the platform's several outages in 2023, the system historically created new image records rather than overwriting the old ones. That behaviour, never corrected at the database level, compounded over three years into a storage and retrieval burden that slowed query times and inflated costs.

The Kenya National Archives and Documentation Service, headquartered at the Riverside Drive complex near Westlands, has been running a parallel deduplication exercise on its historical photograph collections since May. That project, using open-source image-hashing tools piloted with support from a Nairobi-based civic tech organisation, had by this week cleared roughly 12,000 flagged duplicate image pairs from digitised colonial-era land records, a small but symbolically important subset of a collection that runs into the millions of items.

What Clean-Up Means in Practice

Deduplication at this scale is not simply a matter of deleting obvious copies. Technicians must distinguish between true duplicates, identical files stored twice, and near-duplicates, where a document was scanned twice under slightly different lighting or resolution settings. The latter category often requires human review before deletion, because discarding the wrong version of a land title scan, for instance, could create downstream legal disputes in areas like Eastleigh, Kayole, or Mathare, where informal tenure is already contested.

The practical upshot for ordinary Nairobi residents is that several eCitizen service categories experienced intermittent slowdowns between Monday and Wednesday this week as database maintenance windows were applied. Users applying for good conduct certificates or good standing letters through the platform reported wait times of up to 48 hours longer than the published service-level standard of three working days.

Agencies are now being advised to implement automated duplicate-detection at the point of image upload rather than relying on periodic retrospective audits. For residents, the immediate advice is straightforward: hold off on resubmitting eCitizen applications that appear stuck, check the platform's status page before lodging duplicate requests, and give the Huduma Centre network until at least mid-July before expecting full processing speeds to return. For a government trying to prove digital governance works without raising taxes, getting this right quickly matters more than officials may publicly admit.
