Delhi's Photo ID Crisis: The Numbers Behind Millions of Duplicate Images Choking Government Databases

More than 1.4 crore duplicate image records are clogging the Delhi government's unified citizen services database, according to internal figures reviewed by The Daily Delhi, creating a backlog that has delayed ration card renewals, voter ID updates, and AAP's flagship doorstep delivery scheme for tens of thousands of residents.

The problem has been quietly building since at least 2023, when Delhi's e-District portal was merged with the National eGov Service Delivery Assessment framework. Every duplicate entry — a scanned photo uploaded twice, a mismatched biometric image tied to two Aadhaar numbers, a JPEG resubmitted after a portal crash — costs the system processing cycles and, ultimately, rupees. NIC officials estimate the cleaning cost at roughly ₹12 per duplicate record resolved through automated deduplication software. Multiply that by 1.4 crore entries and the figure crosses ₹16 crore before a single human auditor touches a file.

Why does this matter right now? Delhi is midway through Phase 4 of its Metro expansion, which is pulling hundreds of thousands of new commuters into the formal digital economy — people registering for concessional passes, women applying for the free-ride scheme introduced under the Kejriwal government, and daily-wage workers from resettlement colonies in Bawana and Narela accessing Shramik Mitra benefits for the first time. Each application requires a clean, verifiable photograph. A duplicate image in the system can freeze a file indefinitely.

Where the Duplicates Are Concentrated

Three clusters account for a disproportionate share of the mess. The South Delhi Municipal Corporation zone covering Okhla and Sarita Vihar, where a 2024 voter list revision drive enrolled an estimated 2.8 lakh new voters in six weeks, generated a duplicate-image rate of nearly 18 percent according to a district magistrate's office review obtained under the Right to Information Act. The second cluster sits inside the Public Distribution System records maintained at the Shakti Sthal grain depot network in North-West Delhi. The third is the Delhi Jal Board's consumer database in the walled city area of Chandni Chowk, where property titles change hands informally and the same flat can carry four different account photographs tied to four different names.

The Delhi State Legal Services Authority flagged the Chandni Chowk data problem in a March 2026 report, noting that 11,000 water connection disputes in Old Delhi could not be resolved at the Patiala House Courts complex partly because the photographic identity records were contradictory.

The Cost in Welfare and Time

Numbers from the Department of Food and Supplies show that between January and May 2026, duplicate-image flags caused 83,000 ration card applications to enter a manual review queue. Average resolution time: 47 days. During the same period, Delhi's average daily temperature peaked at 46.2°C in May, meaning tens of thousands of families were waiting nearly seven weeks for subsidised grain entitlements during a brutal summer.

The National Informatics Centre, which maintains the backend infrastructure at its CGO Complex servers in Lodhi Road, has deployed a facial recognition deduplication module since April 2025. The module claims a 94 percent accuracy rate on clean images. The catch: roughly 31 percent of the duplicate entries involve low-resolution photographs scanned at Jan Seva Kendras in areas such as Trilokpuri and Mustafabad, where hardware is old and lighting is poor. The algorithm cannot reliably match those images and flags them for human review, returning the problem to the same overloaded clerks.

Officials at the Delhi government's IT Department have told departmental committees that a hardware refresh for 214 Jan Seva Kendras across the city is budgeted at ₹43 crore in the 2026-27 allocation, with procurement expected to begin by September. That timeline depends on central government clearance under the Digital India framework, which has been pending since February.

For residents stuck in the queue, the advice from legal aid workers at the Delhi High Court Legal Services Committee is blunt: file a fresh application in person at the district collectorate, carry two forms of photo ID, and request a real-time Aadhaar seeding confirmation slip. It is slower than the app. It is also, for now, more reliable.
