How Delhi's Public Records Ended Up Full of Duplicate Images — and Why Officials Are Finally Being Forced to Fix It

Delhi's municipal digitisation drive, launched with considerable fanfare under multiple administrations, is confronting an unglamorous problem: thousands of duplicate images embedded in public-facing government databases, from voter identity portals to property registration records maintained by the Delhi Development Authority. The issue is not new, but pressure from a Right to Information audit completed in early 2026 has pushed it into the open.

The backstory matters because it explains why a technical nuisance has become a governance headache. When the Aam Aadmi Party accelerated its e-governance push after 2020 — centralising services through the Delhi Integrated Multi-Modal Transit System data nodes and the MCD's unified citizen portal — departments were given hard deadlines to upload existing paper files. Speed, not quality control, was the operating priority. Photographs of residents, properties and documents were scanned multiple times across departments that were not talking to each other, and duplicate entries compounded with every system migration.

From Paper Files to a Pixel Pile-Up

The Municipal Corporation of Delhi, unified under a single body in May 2022 after the central government merged three legacy corporations, inherited three separate digital archives — each with its own scanning protocols. Officers at the Civic Centre on Minto Road have described the merger as compressing years of cleanup work into a compressed window. Property files from Shahdara in the east and Najafgarh in the west were digitised by different vendors using different resolution standards, meaning the same building photograph sometimes exists in four or five separate entries with slightly different metadata tags. Deduplication software flagged roughly 1.4 lakh such image conflicts in the MCD's internal audit for fiscal year 2025-26, according to documents tabled at a standing committee meeting in March 2026.

The Delhi government's own Revenue Department, which handles land and tenancy records at offices stretching from Kashmere Gate to Dwarka Sub-City, ran into parallel trouble when it tried to integrate with DigiLocker in 2023. Citizens uploading Aadhaar-linked photographs for property mutation requests found their images occasionally cross-populated into unrelated files — a bug traced to a session-handling error in the third-party integration layer. The department patched the immediate flaw, but the underlying duplicate records remained.

Why 2026 Is the Year This Gets Addressed

Two forces have converged to make 2026 the inflection point. First, Delhi Metro Rail Corporation is deep into Phase 4 construction, which requires fresh land acquisition records for corridors including the Janakpuri West to R.K. Ashram stretch and the Aerocity extension. Flawed image records in DDA and revenue files directly slow down the acquisition verification process, creating legal exposure. Second, the Election Commission of India launched a voter roll revision drive in January 2026 that flagged a significant number of duplicate photograph entries in the capital's electoral database — a politically sensitive finding given the competitive electoral terrain between the AAP administration and the BJP-backed central government bodies.

The practical cost is measurable. A government-empanelled technology consultant's estimate presented to the Delhi Assembly's Public Accounts Committee in February 2026 put the cost of a full deduplication exercise across five major departments at approximately ₹34 crore over 18 months. That figure covers image hashing, manual verification of contested records, and training for departmental data managers. Critics on the committee argued the figure should be charged back to the original digitisation vendors whose contracts lacked quality-assurance clauses.

For Delhi residents, the immediate implication is practical: anyone renewing documents or applying for services that require photograph verification — including property mutation at sub-registrar offices in Tis Hazari or licences processed through South Delhi Municipal offices in Saket — should expect longer processing times through at least the end of 2026 while reconciliation work continues. Officials have advised applicants to carry both digital and physical copies of all identity photographs to appointments. The broader cleanup, if it proceeds on the timeline the Public Accounts Committee has endorsed, should produce a cleaner, deduplicated civic image repository before the next round of local body elections — whenever those are eventually scheduled.
