How Delhi's Public Records Ended Up Flooded With Duplicate Images — And Why Fixing It Has Taken Years

Delhi's civic digitisation push, launched with considerable fanfare under the e-District portal around 2015, was meant to drag a paper-heavy administration into the modern age. Instead, government departments across the capital spent the better part of a decade accumulating a parallel problem: thousands of duplicate image files — scanned birth certificates, property records, ration card photographs, caste certificates — stored redundantly across servers, slowing retrieval systems and inflating storage costs at a time when the city's IT budget was already stretched thin.

The issue matters now because Phase 4 of the Delhi Metro expansion, which involves significant land acquisition paperwork along corridors including the Janakpuri West–RK Ashram Marg line, has forced the Delhi Development Authority and the Revenue Department to process unprecedented volumes of scanned documentation simultaneously. Duplicate images in those records are not merely a clerical nuisance — they have delayed compensation processing for affected residents and created discrepancies in official land registers that courts have flagged during hearings at the Delhi High Court.

A Digitisation Drive That Moved Faster Than Its Quality Controls

The origins of the problem trace back to the rollout of the Common Service Centres across localities including Karol Bagh, Dwarka Sector 10, and Lajpat Nagar between 2014 and 2017. Operators at these kiosks, paid per transaction rather than per verified document, had a structural incentive to scan quickly rather than carefully. When a document scan failed — because of a paper jam, a connectivity dropout, or an operator error — the software often defaulted to saving both the failed attempt and the retry. Neither file was automatically flagged or discarded.

The Delhi e-Governance Society, which oversees the technical backbone of citizen services in the capital, identified the scale of the duplication problem internally around 2019, according to publicly circulated meeting agendas from that period. Remediation, however, required cross-departmental coordination that proved difficult to sustain. The Revenue Department, the Municipal Corporation of Delhi — which was then still divided into three separate bodies before its reunification in 2022 — and the Delhi State Archives each maintained partially overlapping but incompatible digital repositories. Deduplication tools applied to one database could not automatically interrogate another.

The reunification of the three municipal corporations into a single MCD in May 2022 was expected to simplify data governance. It created a single administrative entity responsible for roughly 1.4 crore property tax records, but the merger also meant reconciling three distinct scanning conventions, three sets of file-naming protocols, and three legacy server environments. IT contractors working on the consolidation, per procurement documents available on the MCD's public tender portal, flagged duplicate image rates of between 18 and 23 percent in certain sub-registers — a figure high enough to cause meaningful errors in automated search functions.

What the Backlog Looks Like on the Ground

At the Citizen Service Bureau on Vikas Marg in East Delhi — one of the busiest document processing counters in the city — staff have described informally to visiting journalists a routine where applicants seeking certified copies of old records are told to return multiple times because the system returns conflicting results for the same file. The problem is most acute for documents originally scanned before 2018, when the e-District platform underwent a server migration that was not accompanied by a full deduplication pass.

The Delhi government's IT Department circulated an internal roadmap in early 2025 for deploying hash-based deduplication software across the Revenue Department's primary servers, with a projected completion window of 18 months. That timeline, if met, would put full remediation sometime in the second half of 2026 — roughly coinciding with the scheduled opening of priority Metro Phase 4 stations and the associated surge in land record queries.

For residents dealing with the backlog today, the practical advice from legal aid offices including the Delhi Legal Services Authority is straightforward: when applying for certified document copies through the e-District portal or in person at Sub-Divisional Magistrate offices in areas like Saket or Civil Lines, submit a written request alongside the application noting the original scan date if known. That additional reference point helps clerks manually distinguish between duplicate entries and speeds up the retrieval process while the automated fix is still pending.
