Hong Kong's Duplicate Image Problem: The Key Decisions Ahead for Government Records and Digital Archives

Hong Kong's government and major public institutions are sitting on a quiet crisis buried inside their own servers. Duplicate digital images — scanned documents, identity photographs, land registry files, court records — have accumulated across multiple departments for years, and the decisions about how to clean them up, who pays, and what gets deleted permanently are now unavoidable.

The issue has sharpened in 2026 because of two converging pressures. The city's push to deepen integration with the Greater Bay Area has demanded interoperable data systems that can talk to Mainland platforms. And the rollout of the iAM Smart+ digital identity framework, which reached 4.2 million registered users by the end of March 2026 according to the Innovation, Technology and Industry Bureau, means that duplicated biometric and identity images lodged across departments represent not just a storage headache but a genuine data-governance risk under Article 23 security frameworks.

Where the Backlog Lives

The Land Registry's offices in Queensway Government Offices, Admiralty, hold decades of scanned title deeds, mortgage instruments and property transfer forms. Staff there have known for years that bulk scanning campaigns in 2009 and 2014 created overlapping image sets when files were rescanned after quality complaints. The problem is mirrored at the Immigration Department's headquarters in Immigration Tower, Wan Chai, where multiple rounds of document digitisation since the 2000s left parallel image libraries that were never formally reconciled.

The Hospital Authority, which manages 43 public hospitals and institutions across the city, faces its own version of the problem in radiology. CT scans and X-ray images taken at Pamela Youde Nethersole Eastern Hospital in Chai Wan and Queen Mary Hospital in Pok Fu Lam are stored across the Clinical Management System, but a government-commissioned review completed in late 2025 identified significant duplication rates in archive folders older than seven years. Resolving those records requires sign-off from both the Department of Health and the Privacy Commissioner for Personal Data, whose office sits at 12/F, 33 Hysan Avenue, Causeway Bay.

Storage is not cheap. Government cloud contracts, managed partly through the Office of the Government Chief Information Officer, have expanded substantially. The 2026-27 Budget allocated HK$2.3 billion to the Digital Government Blueprint programme overall, but individual departments still bear their own infrastructure costs, and duplicated image libraries inflate those bills every quarter without delivering any operational benefit.

What Happens Next

The critical fork in the road arrives this autumn. The OGCIO is expected to publish revised data-management guidelines before October 2026, and departments will then have 18 months to submit compliance plans. The real decision is not technical — deduplication software from vendors active in Hong Kong, including local systems integrators operating out of Cyberport in Pok Fu Lam, can handle the matching work — but legal and political.

Permanent deletion of government image records triggers obligations under the Public Records Office Ordinance, and the Government Records Service, based in the Central Government Offices complex in Tamar, must certify that nothing of archival value is being destroyed. For biometric images specifically, any deletion programme will require the Privacy Commissioner's formal endorsement, adding another layer of institutional coordination that has historically slowed similar exercises.

There is also a staffing dimension. Many of the departments worst affected by duplication relied on contract digitisation teams who no longer exist, which means the institutional memory about exactly what was scanned, when, and under which filing protocol has partly walked out the door — a trend accelerated by the emigration wave that has thinned the civil service bench in mid-grade technical roles since 2021.

The practical advice for departments watching this unfold is to begin preliminary audits now, before the OGCIO guidelines land, so that internal figures are ready when compliance deadlines are set. Waiting for the official framework before even counting the problem is how backlogs become crises. The city has the tools, the legal architecture, and the digital infrastructure investment to resolve this cleanly. The question is whether the coordinating will between agencies materialises before the 18-month clock runs out.
