Cairo's Digital Archives Are Drowning in Duplicate Images — Here's How the City Stacks Up Against Istanbul and Nairobi

Tens of thousands of duplicate photographs are clogging the digital archives of at least three major Cairo institutions, according to archivists working inside those systems, slowing retrieval times and inflating cloud storage costs at a moment when public budgets are already stretched thin under Egypt's ongoing IMF fiscal adjustment programme.

The problem is not unique to Cairo. But how the city is responding — and how fast — reveals a gap between Egypt's digital ambitions and the technical infrastructure actually in place to support them.

The issue gained sharper urgency this year because of two converging pressures. First, the Egyptian government accelerated the digitisation of public records and heritage materials as part of a broader push tied to the New Administrative Capital project east of Cairo, which envisions a paperless administrative state by 2030. Second, the sharp devaluation of the Egyptian pound since 2022 has made foreign-currency cloud storage contracts — typically priced in US dollars — substantially more expensive for government entities paying in local currency.

Where Cairo Is Falling Behind

The Egyptian National Library and Archives, headquartered on Corniche El Nil in downtown Cairo, has been digitising physical collections since the early 2010s. Staff there are working through a backlog that includes photographic records from the Nasser and Sadat eras. The problem is that multiple scanning rounds, conducted by different contractors over different years, produced overlapping digital files with no unified deduplication protocol applied after the fact. A similar situation affects the photographic holdings at the Egyptian Museum on Tahrir Square, where digitisation work conducted under a European Union-funded heritage programme left image libraries containing redundant files that staff are still manually auditing.

Compare that to Istanbul, where the Istanbul Metropolitan Municipality launched a city-wide asset deduplication project in 2023 using open-source perceptual hashing tools integrated directly into its content management system. By the end of that programme's first phase, the municipality reported removing more than 40 percent of redundant image files from its public portal — a figure cited in a presentation to the European Smart Cities conference in October 2024. Nairobi's City Hall took a different approach, contracting with a Kenyan technology firm in late 2024 to run automated hash-matching across its urban planning photo database, clearing roughly 1.2 terabytes of duplicate data within four months.

Cairo has no equivalent citywide programme yet. The work is happening institution by institution, manually, and without shared standards between agencies.

The Cost and the Road Ahead

Storage is not abstract. Egyptian government entities using AWS or Microsoft Azure pay in US dollars, and with the pound trading at roughly 49 to the dollar as of mid-2026, a storage bill that cost the equivalent of 500,000 Egyptian pounds two years ago now costs considerably more in local currency terms for the same amount of data. Eliminating duplicates is, in that context, a direct fiscal saving.

The Ministry of Communications and Information Technology, which oversees the national digital infrastructure agenda from its offices in the Smart Village technology park on the Cairo–Alexandria desert road, has acknowledged the duplication problem in general terms in its Egypt Digital Economy Strategy documents. No dedicated deduplication line item has been publicly identified in ministry budget disclosures reviewed by The Daily Cairo.

What practical options exist for institutions waiting for a national standard? Archivists at several Cairo institutions are already experimenting with open-source tools — including PhotoDNA-adjacent perceptual hashing libraries — that can flag near-duplicate images without requiring expensive licensed software. The Cairo-based tech community at Flat6Labs, the startup accelerator on Ahmed Orabi Street in Mohandessin, has seen at least two early-stage companies pitch document and image management tools aimed at government clients in the past eighteen months, suggesting local entrepreneurial interest in filling the gap.

The practical advice from archivists who have worked through similar backlogs elsewhere is consistent: start with a hash-based audit before touching any files, set a single naming and metadata convention across all future scans, and never run a second digitisation project without first checking what the first one produced. Cairo's institutions have the expertise. The missing piece is a coordinating body with the authority — and the budget — to enforce a common standard before the next round of scanning begins.
