Duplicate Images in Government Portals Are Costing Singaporeans Time and Trust — Here's Why It Matters

Scan any HDB InfoWeb listing, MyInfo profile page or HealthHub portal this week and you will find them: duplicate property photos, repeated identification thumbnails, and recycled stock images appearing across multiple unrelated service pages. The problem is not cosmetic. Residents trying to verify flat listings in Tampines, Sengkang and Buona Vista have reported confusion over whether images are current, leading some to make site visits for properties already sold or altered beyond recognition.

This matters now because Singapore's Smart Nation drive has pushed an enormous volume of government transactions online. The Infocomm Media Development Authority reported that more than 95 percent of government services were available digitally as of 2023. That infrastructure was built fast. Quality controls over digital assets — particularly image libraries — have not always kept pace. When a resident in Jurong West pulls up a rental flat listing on HDB's resale portal and sees a bathroom photograph that appears on three other listings, the signal is simple: something here cannot be trusted.

Where the Problem Shows Up Most

The duplication issue cuts across at least three major government-linked digital systems. On the HDB resale and rental portals, agents and individual sellers frequently upload images without any automated deduplication check, meaning a single photograph taken in a Bedok North block can appear under listings at Woodlands, Clementi and Ang Mo Kio simultaneously. The National Library Board's digital archive, run through its NLB OverDrive and library.gov.sg infrastructure, has separately flagged internal review findings showing legacy digitisation batches contain duplicate scans filed under different catalogue numbers — a problem that wastes storage and scrambles search results for researchers.

The Central Provident Fund Board's member portal, used by roughly 4.1 million active CPF members as of the most recent annual report, relies on identity-linked profile images that can propagate duplicates when accounts are updated after name changes or document renewals. Users have described seeing outdated photos persist alongside current ones during the transition window, raising concerns about which image represents their verified identity for financial transactions.

Private platforms mirror the issue. PropertyGuru, which listed over 80,000 active property ads in the first quarter of 2026, has faced user complaints on forums including HardwareZone and Reddit's r/singapore about duplicate floor plan images appearing across competing listings for units in the same development — particularly new launches at One-North and the Lentor Hills cluster in Ang Mo Kio.

What Deduplication Actually Involves — and What Comes Next

Duplicate image replacement is a technical process involving perceptual hashing — software that assigns a fingerprint to each image and flags near-identical versions regardless of minor cropping or compression differences. Tools using this method can typically process tens of thousands of images per hour. The cost of integrating such tools into an existing content management system ranges widely, but enterprise-grade solutions used by platforms of HDB's scale typically run from S$50,000 to several hundred thousand dollars for initial deployment, depending on legacy system compatibility.

GovTech, the agency responsible for building and maintaining Singapore's digital government infrastructure, has previously applied machine learning image checks to the SingPass Face Verification system. Extending similar logic to asset management across portals is technically straightforward, though it requires coordination between agencies that often operate their own separate content management systems.

For residents, the practical advice is this: when using HDB's portal or PropertyGuru to shortlist a flat, request the seller or agent provide date-stamped photographs with the address visible, or arrange a video walkthrough before committing to a viewing appointment. For CPF or government profile matters, log into Singpass, navigate to your profile settings and manually verify that only one active profile image is linked to your NRIC record. If duplicates appear, the Singpass helpline at 6335-3533 handles image-related account queries during office hours. The technology fix will come. Until it does, residents carry the verification burden themselves.
