Hong Kong's Duplicate Image Problem: The Key Decisions That Will Shape the City's Visual Archive

Hong Kong's public and commercial digital repositories are sitting on a growing crisis of duplicate imagery — redundant files consuming server capacity, inflating licensing costs, and undermining the accuracy of everything from government planning portals to news archives. The problem has reached a tipping point in mid-2026, with major institutions now facing a hard deadline to act before annual IT budget cycles close in the fourth quarter.

The issue matters now because the city is pushing hard to position itself as the Greater Bay Area's data-management hub, a pitch that depends on demonstrable digital hygiene. Singapore's GovTech directorate rolled out a centralised deduplication framework for state digital assets in 2024, and that gap has not gone unnoticed by procurement officers in Central. Every month of inaction compounds the backlog.

Where the Bottlenecks Are Forming

The Hong Kong Public Libraries system, which maintains digitised collections across its 70-plus branches including the flagship branch at Harbour Road in Wan Chai, has publicly acknowledged the need for a rationalisation of its digital asset management platform in its 2025–26 annual service plan. The Libraries Authority flagged that its catalogue contains tens of thousands of image records with unresolved duplication flags — a legacy of three separate digitisation drives conducted between 2015 and 2022 that used incompatible metadata standards.

The Hong Kong Science and Technology Parks Corporation (HKSTP), operating out of its Pak Shek Kok campus in Tai Po, has similarly been wrestling with how to advise the roughly 1,100 companies housed in its incubator programmes on compliant image-asset practices. Startups working in e-commerce, property technology, and media production have been told in internal guidance sessions that duplicate image libraries can trigger licensing double-billing worth tens of thousands of Hong Kong dollars per year on mid-tier commercial photo platforms.

The problem is not abstract. Commercial storage costs in Hong Kong data centres run materially higher than in comparable Tier-1 markets. Analysts tracking the local cloud market have noted that organisations retaining unrationalised image archives face avoidable overhead on an annual basis, with redundant storage among the most addressable line items. For smaller newsrooms and NGOs operating out of offices in Sheung Wan and Mong Kok, that is not negligible money.

The Decisions That Cannot Wait

Three choices now sit in front of decision-makers at both government agencies and private organisations. First, which deduplication standard to adopt — perceptual hashing, exact-match checksum, or the more computationally intensive AI-assisted similarity detection that several Mainland vendors demonstrated at the Hong Kong ICT Awards 2025 showcase in December. Each carries different cost and accuracy trade-offs. Second, who owns the rationalised archive once duplicates are removed — the originating department, a centralised custodian, or a third-party managed service. Third, whether to purge duplicates outright or archive them in cold storage, a distinction with real implications for organisations subject to the Evidence Ordinance or records-retention requirements under the Public Records Office guidelines.

The Office of the Government Chief Information Officer has been developing a refresh of its cloud-first policy, with a consultation period that closed in May 2026. Any directive on duplicate asset management is expected to flow from that policy update, though no publication date has been confirmed publicly.

For private organisations that cannot wait on government timelines, the practical path is straightforward: conduct an internal audit of all image repositories before the end of September, assign a named data steward to sign off on deletion decisions, and test deduplication tools on a bounded subset — say, a single department's archive — before rolling out city-wide. Firms in Cyberport, the digital-hub campus in Pok Fu Lam, have already begun sharing vendor notes through the Cyberport Creative Micro Fund alumni network. The model is worth watching. The costs of delay, measured in storage fees, legal exposure, and competitive credibility, are only going one way.
