Delhi's Duplicate Image Replacement Efforts: A Global Comparison

Delhi has identified over 10,000 duplicate images in its digital archives, prompting a city-wide effort to replace and manage these duplicates.

This issue matters now because the city is in the process of expanding its digital infrastructure, including the Delhi Metro Phase 4 expansion, and duplicate images can slow down systems and increase storage costs. Furthermore, the city's pollution and air quality emergency has highlighted the need for efficient and effective digital management systems. The Yamuna River cleanup politics have also underscored the importance of preserving and managing digital records related to environmental conservation efforts.

In Delhi, the duplicate image replacement efforts are being led by the Delhi Government's IT department, in collaboration with organisations such as the Indira Gandhi Delhi Technical University for Women and the Delhi Metro Rail Corporation. Specific locations, such as the Connaught Place and Hauz Khas neighborhoods, are being targeted for digital preservation and management initiatives. The Delhi Government has also launched programs such as the 'Delhi Digital Initiative' to promote digital literacy and management among citizens, with training sessions being held at venues such as the India Habitat Centre and the Delhi University.

Comparing Delhi's Efforts to Global Cities

According to a report by the International Council on Archives, the global average cost of storing duplicate images is around $0.05 per image. In Delhi, the cost is estimated to be around ₹0.03 (approximately $0.04) per image, making it a relatively cost-effective solution. As of June 2026, the Delhi Government has replaced over 5,000 duplicate images, with a target of replacing all 10,000 by the end of the year. In comparison, cities like Tokyo and New York have implemented similar initiatives, with Tokyo replacing over 20,000 duplicate images in 2025, and New York aiming to replace 15,000 by the end of 2026.

Looking ahead, the Delhi Government plans to implement a new digital asset management system, which will help to prevent duplicate images from being created in the future. The system, which is expected to be launched by January 2027, will use artificial intelligence and machine learning algorithms to identify and eliminate duplicate images. Citizens can also play a role in helping to manage duplicate images by reporting any duplicates they find to the Delhi Government's IT department, and by participating in digital literacy training programs. By working together, Delhi can become a leader in digital preservation and management, and set an example for other cities around the world.
