How Singapore's Digital Records Got Clogged With Copies: The Long Road to Duplicate Image Replacement

Singapore's public agencies are sitting on a problem that built up quietly over years: millions of duplicate images embedded across government portals, HDB flat listings, CPF board documents, and national identity record systems. The push to systematically replace and consolidate these redundant files — a process now formally referenced in GovTech's digital infrastructure roadmap — did not emerge from a single crisis. It emerged from the compounding consequences of how Singapore digitised, fast and repeatedly, without a unified image management standard.

The stakes are real. Bloated image repositories slow down load times for services that millions of residents use weekly, from the MyInfo portal on Singpass to the HDB resale flat listing system on the Housing Development Board's main website. When a duplicate image sits in three separate database tables, each copy must be retrieved, stored, and backed up independently. At scale — across an estimated 1,600-plus government digital services catalogued under the Singapore Government Developer Portal as of 2025 — that inefficiency compounds into genuine infrastructure cost.

How the Duplication Problem Accumulated

The roots go back to the early 2000s, when Singapore's Smart Nation ambitions were still taking shape in policy documents rather than production systems. Individual ministries and statutory boards built their own content management systems at different times, procured by different vendors, with no shared asset library. The Ministry of Manpower digitised its forms independently of the Inland Revenue Authority of Singapore. The National Library Board's digital collections team operated separately from the National Heritage Board's image archives at the Asian Civilisations Museum on Empress Place. Each agency uploaded its own copies of shared assets — logos, instructional diagrams, map thumbnails — because there was no technical pathway to reference a single master file.

GovTech, established as a statutory board in October 2016, inherited this fragmented landscape. Its mandate included rationalising the backend systems of more than 90 public agencies, but image asset management was not the headline priority in the early years. The focus fell on identity infrastructure, such as the National Digital Identity platform, and transactional services. Image duplication was a known issue, logged and deferred.

The tipping point came partly from the government's own cost scrutiny. Singapore's public sector ICT spending, which the Infocomm Media Development Authority has tracked through annual procurement data, has consistently ranked among the highest in the Asia-Pacific region on a per-capita basis. When internal audits began flagging storage costs as a growing line item, the image archive problem became harder to defer. Cloud migration projects — several agencies moved to commercial cloud infrastructure between 2020 and 2023 under the Government Commercial Cloud programme — made the true cost of storing redundant files visible in ways on-premise servers had obscured.

What Replacement Actually Involves

Duplicate image replacement is not simply deleting copies. Each redundant file must be traced to its references across HTML, PDF templates, and database records before the original can be retired and a canonical version substituted. For agencies like the Urban Redevelopment Authority, whose OneMap platform serves as the base layer for dozens of third-party applications, a poorly executed replacement can break embedded maps in external services without warning.

GovTech has been piloting automated deduplication tools since at least 2023 as part of the broader Singapore Government Tech Stack initiative. The approach uses hash-based matching — comparing file signatures rather than filenames — to identify true duplicates regardless of what different departments called the same image when they uploaded it years apart.

For residents, the practical outcome should eventually be faster-loading pages on government services, particularly on mobile networks where image payload size directly affects experience. HDB's resale portal, which handled more than 27,000 transactions in 2024 alone, is among the high-traffic services where the performance gains are expected to be most noticeable.

Agencies have been directed to complete initial deduplication audits before migrating to the next version of the Singapore Government Design System, the standardised front-end framework that now governs how public-facing digital services are built and maintained. That migration schedule makes the image cleanup work time-sensitive rather than aspirational — and finally gives it the deadline that years of good intentions never produced.
