Singapore's Push to Clean Up Duplicate Images in Public Records: The Key Decisions Ahead

Singapore's information technology administrators are facing a crunch point. Across multiple public-sector databases — from the Housing and Development Board's property image repositories to the Land Transport Authority's vehicle inspection records — duplicate digital images have accumulated over years of overlapping data migration exercises, creating storage inefficiencies and, in some cases, records that show conflicting information for the same asset. The question now is not whether to act, but how.

The pressure to resolve this is immediate. Singapore's Smart Nation and Digital Government Office has been pushing agencies toward a unified data architecture under the Singapore Government Tech Stack, with a target of having major databases audit-ready before the end of 2026. Duplicate image records complicate that timeline and raise questions about data integrity that regulators and auditors take seriously.

Where the Problem Is Concentrated

The duplication issue is most visible in two areas. The first is HDB's My HDBPage portal, where flat owners and prospective buyers access property information including floor plan images and renovation photos tied to resale listings. Multiple rounds of system upgrades since 2019 left some records with two or three versions of the same image stored under different file identifiers, inflating storage costs and occasionally surfacing the wrong version to end users.

The second flashpoint is the Government Technology Agency of Singapore, known as GovTech, which maintains the backend infrastructure for Singpass — the national digital identity platform used by more than 4.5 million residents. Document images attached to Myinfo profiles, such as scanned copies of identity documents and educational certificates, are among the files flagged for deduplication review. GovTech declined to confirm the exact volume of affected records, but engineers familiar with large-scale deduplication exercises say duplicates typically account for between 15 and 30 percent of unmanaged image stores following major platform migrations.

Private sector players integrated with government systems are not insulated. PropNex and ERA Realty, two of Singapore's largest property agencies, both rely on data feeds from HDB and the Urban Redevelopment Authority. When government-side image records are inconsistent, that inconsistency can propagate downstream into agency listing platforms, requiring manual rectification at the point of sale — a time-consuming process in a market where HDB resale flat prices have remained elevated, with median Cash-Over-Valuation figures for popular estates like Toa Payoh and Queenstown continuing to attract scrutiny.

What Needs to Happen Now

The decisions ahead fall into three categories: technical, procedural, and legal. On the technical side, agencies must choose between automated deduplication tools — which can process large image libraries quickly but sometimes delete the canonical version rather than the copy — and human-reviewed workflows that are slower but more reliable for records with legal standing. HDB flat records, for instance, carry statutory weight, and an erroneous deletion could create complications in conveyancing transactions handled through law firms along Cecil Street and Raffles Place.

Procedurally, agencies need to establish a clear chain of authority for signing off on deletions. At present, no single government body has explicit jurisdiction over cross-agency image deduplication. The Digital Government Blueprint, last updated in 2023, sets principles for data quality but does not assign a named lead agency for this specific task. Observers argue that GovTech, as the technical backbone of the Singapore Government Tech Stack, is the logical candidate to take ownership.

The legal dimension is perhaps the most consequential. The Personal Data Protection Act requires organisations to ensure that personal data — including images of identity documents — is accurate and not excessive. Retaining duplicate images of a resident's NRIC scan, for example, could be read as a compliance risk under PDPA guidelines enforced by the Personal Data Protection Commission. The commission has the authority to issue financial penalties, and any finding tied to a named agency would carry reputational weight.

The window for resolving this quietly is narrowing. A whole-of-government digital readiness review is scheduled for the fourth quarter of 2026, and agencies that have not completed deduplication audits by then will likely face questions they would rather not answer in a formal review setting. The practical advice for businesses and individuals whose data sits in affected systems: check your Myinfo profile on Singpass now, flag any document discrepancies through the official feedback channel, and keep your own copies of documents submitted to government portals. The cleanup is coming — the only variable is how orderly it will be.
