Singapore Takes Aim at Duplicate Images Online — And It's Moving Faster Than London or Tokyo

Singapore's Infocomm Media Development Authority confirmed earlier this year that duplicate and replicated images across government-linked digital portals had become a measurable drag on public-facing services — slowing load times, inflating storage costs and muddying search results on platforms used daily by hundreds of thousands of residents. The problem is neither glamorous nor headline-grabbing, but the administrative cost is real and the fix is proving harder than officials initially projected.

The timing matters. Singapore has spent the better part of three years positioning itself as a regional AI and data governance hub, most visibly through the National AI Strategy 2.0 launched in December 2023. Redundant image data sitting inside government content management systems undermines that pitch. If the city-state cannot maintain clean, well-governed internal datasets, the credibility of its broader data economy ambitions takes a hit — particularly as it competes with Seoul and Zurich for regional headquarters of data-intensive multinationals.

What Singapore Is Doing Differently

The IMDA has been working since at least mid-2025 with GovTech — the agency behind the Singpass ecosystem and the LifeSG super-app — to run automated deduplication sweeps across shared content repositories. The work is unglamorous: hash-matching algorithms flag visually identical or near-identical files, which are then queued for human review before deletion. GovTech's systems support services used across dozens of statutory boards, meaning a single duplicate image uploaded by, say, the Housing Development Board for a Tampines estate tender notice can propagate silently across multiple downstream portals within hours.

The HDB alone manages thousands of project listings at any time, many of them illustrated with block photographs and floor-plan diagrams that get re-uploaded rather than linked. A similar problem exists on the OneService portal, which aggregates municipal feedback from residents in estates stretching from Jurong West to Pasir Ris. Community managers uploading photographs of damaged footpaths or flickering void-deck lights have historically had no built-in duplicate check — meaning the same cracked pavement in Buona Vista could be logged with three different photographs of the same crack.

London's Government Digital Service — which oversees GOV.UK — acknowledged a comparable image duplication problem as far back as 2021, but progress has been slow. As of the GDS's own published reports, thousands of asset duplicates remain unresolved across departmental microsites that migrated onto the central platform. Tokyo's Digital Agency, established in September 2021, has made deduplication part of its broader data standardisation mandate, but is still contending with legacy municipal systems that predate the agency itself. Singapore's advantage is structural: it has fewer agencies, tighter central coordination and a single dominant content platform in the form of the government's AnswerSG and Moments of Life infrastructure.

The Cost and What Comes Next

Cloud storage costs in Singapore, while not published at the granular per-agency level, follow regional enterprise pricing. Amazon Web Services S3 standard storage in the Asia Pacific (Singapore) region is listed at around USD 0.025 per gigabyte per month. For agencies managing image libraries in the tens of terabytes — not unusual for a body like the Urban Redevelopment Authority, which hosts decades of planning maps, streetscape photographs and development application images — even a 20 percent reduction in duplicated assets translates to meaningful recurring savings.

The deduplication push is also feeding into Singapore's green corridor commitments. The government's Green Plan 2030 includes a digital sustainability component tied to reducing unnecessary data centre energy consumption. Eliminating redundant files reduces processing and retrieval load, however marginally, and that argument has given the technical project additional political cover inside agencies that might otherwise deprioritise it.

For residents, the most visible near-term benefit will likely show up in search quality on government portals — fewer redundant image results when looking up an HDB block in Clementi or a hawker centre redevelopment in Toa Payoh. GovTech has not published a completion timeline for the deduplication work, but the agency is expected to include progress metrics in its annual report later in 2026. Cities watching Singapore's approach closely include Helsinki and Amsterdam, both of which have flagged similar asset-management challenges across their own centralised civic platforms.
