Thousands of Delhi residents have discovered in recent weeks that photographs stored on government and civic portals — images submitted as part of housing applications, ration card renewals, and property documentation — have been replaced by generic placeholder images or entirely different photographs, the result of an automated deduplication process run across multiple Municipal Corporation of Delhi and Delhi government databases. For families whose land ownership, welfare eligibility, or tenancy rights depend on those image records, the consequences are not technical. They are existential.
The deduplication drive, which MCD officials confirmed began in March 2026 as part of a broader data consolidation effort under the Delhi e-Governance Society, was designed to clear redundant image files and reduce server load across the Unified Delhi Portal. What it has done instead, according to complaints filed at ward offices across East and North Delhi since April, is trigger a cascade of mistaken deletions in which original, legally significant photographs were flagged as duplicates of other residents' files and overwritten.
Chandni Chowk to Kondli: Where the Damage Runs Deepest
In the lanes behind Fatehpuri Masjid in Chandni Chowk, traders who registered their shops under the PM SVANidhi scheme — a central government micro-loan programme for street vendors launched in 2020 — say their storefront photographs, submitted as proof of business address, have been replaced on the portal. Without those images, fresh loan cycles or licence renewals require the entire documentation process to be restarted in person at the Chandni Chowk zonal office on Esplanade Road, a process that can take four to six weeks.
Resettlement colonies along the Yamuna floodplain have been hit harder. In Kondli and Trilokpuri in East Delhi, residents who submitted photographs for the Delhi government's Jahan Jhuggi Wahin Makaan scheme — which promises in-situ housing to slum dwellers on land they already occupy — say their image files on the Delhi Urban Shelter Improvement Board portal now show either blank icons or photographs that belong to other applicants. DUSIB is the nodal agency for the programme. The confusion is compounding delays in a scheme that was already running years behind its original timelines.
In Sultanpuri in North-West Delhi, a local NGO called Sanjhi Umeed that assists first-generation documentary applicants says it has logged more than 340 individual complaints of missing or replaced images since May 2026 alone. The organisation operates out of a single-room office near Sultanpuri Metro Station and has been forwarding cases to the MCD's North Zone grievance cell. Staff there say response times currently stretch beyond 30 days per case.
A Digital System With Analogue Consequences
The practical damage maps closely onto who can least afford it. Delhi's ration card database, administered by the Department of Food, Supplies and Consumer Affairs, requires a current photograph for each cardholder. A replaced or missing image freezes the card until reverification. With Delhi's below-poverty-line ration price for wheat held at Rs 2 per kilogram under the National Food Security Act, the loss of a functional ration card is not a paperwork inconvenience — it is a direct hit to household food budgets.
Civic technology researchers who have studied similar deduplication errors in Bengaluru's Bruhat Bengaluru Mahanagara Palike database in 2023 noted that automated image-matching systems typically carry a false-positive rate of between 3 and 7 percent when applied to low-resolution citizen photographs taken under inconsistent lighting — exactly the conditions under which most Delhi portal images were captured at Common Service Centres across the city.
MCD has not yet released a public figure for how many image records were affected. Delhi e-Governance Society has not responded to requests for comment on a remediation timeline.
Residents whose images have been replaced are advised to visit their nearest Jan Seva Kendra — there are more than 200 across Delhi — with original hard-copy documents and photographs, and to file a written grievance citing the Unified Portal complaint reference system under category code IMG-ERR. Ward-level officials in at least Shahdara and Central Delhi districts have confirmed that manual re-uploads are being accepted without fresh appointment slots through July 31, 2026. After that date, standard processing queues apply.
