Manila's Digital Archives Are Riddled With Duplicate Images — And the Numbers Tell a Damning Story

At least 34 percent of image files stored across Manila City Hall's publicly accessible digital document repositories are duplicates — identical or near-identical photographs filed under different names, often uploaded multiple times across separate departments. That figure, drawn from an internal audit circulated within the Manila Information and Communications Technology Office earlier this year, points to a structural problem that has quietly inflated the city's data storage costs and degraded the performance of key public-facing portals since at least 2023.

The timing matters. Manila is currently midway through its Digital Governance Roadmap, a program launched in January 2025 that committed the city to consolidating its departmental databases into a single unified platform by the end of 2026. With that deadline six months away, the duplicate image problem has emerged as one of the most concrete obstacles to that integration. You cannot merge databases cleanly when one department has filed the same photograph of, say, a cracked sidewalk along Padre Burgos Avenue under four different ticket numbers.

Where the Bloat Is Worst

The Urban Development Office in Ermita and the Permits and Licensing Division in the Intramuros administrative complex have been identified internally as the two units with the highest rates of file redundancy. Both offices shifted to digital submission workflows in 2022, requiring applicants to upload supporting images — site photos, damage documentation, building façade shots — as part of permit and complaint applications. Without an automated deduplication layer in place at the point of upload, the same image submitted by a contractor for multiple permit stages simply stacked up.

The Manila Health Department's community nutrition monitoring portal, which barangay health workers across Tondo and Sampaloc use to log child assessment photos, was flagged separately. Field workers uploading on low-bandwidth mobile connections sometimes hit timeout errors and resubmit, generating duplicate entries. By December 2025, the nutrition portal alone had accumulated an estimated 18,000 redundant image files, according to figures from the ICT Office audit summary. Each duplicate entry also creates a corresponding ghost record in the case management database, inflating reported caseload numbers and distorting the data used to allocate resources.

Storage is not cheap. The city currently pays for cloud hosting through a contract with a local government IT services provider, with per-gigabyte costs that the ICT Office estimated would rise by roughly 22 percent under the next contract renewal, due in October 2026. The duplicate image load, which the audit pegged at approximately 2.3 terabytes of redundant data across all audited departments, is a direct line item on that bill — money that could otherwise fund equipment for barangay health stations or bandwidth upgrades for the city's public WiFi nodes along Roxas Boulevard.

What Fixing It Actually Requires

Deduplication is not a novel technical challenge. Hash-based image matching — software that generates a unique fingerprint for each file and flags identical copies — has been standard practice in enterprise content management for years. The Manila ICT Office has proposed deploying an open-source deduplication tool across all departmental servers in a phased rollout beginning in September 2026, starting with the Permits Division and the Urban Development Office before expanding citywide.

The harder problem is governance, not technology. Each department currently manages its own upload protocols, and there is no city-wide image naming convention or mandatory metadata standard. A photograph uploaded by the Department of Public Works and Highways district office covering the Binondo and Quiapo corridor uses different file tagging than the same photograph uploaded by a barangay official reporting the same infrastructure defect. Until there is a unified intake standard — something the Digital Governance Roadmap technically mandates but has not yet enforced — deduplication tools will keep running cleanup operations on a problem that upstream processes continue to generate.

Residents and community organisations that interact with Manila's online complaint and permit systems can help in the short term by avoiding multiple resubmissions when upload confirmations are slow. The ICT Office's public-facing helpdesk, reachable through the Manila e-Gov portal, is the appropriate channel for reporting failed uploads — not a second submission of the same file. For the city's part, the September rollout date is the number to watch.
