Copenhagen's Duplicate Image Replacement Efforts: A Global Comparison

Copenhagen is currently dealing with a significant issue of duplicate image replacement, with over 10,000 instances reported in the past year alone, according to data from the City of Copenhagen's IT department.

This issue matters now because it has significant implications for the city's digital infrastructure and cybersecurity. With the rise of artificial intelligence and machine learning, duplicate image replacement can be used to spread misinformation and propaganda, making it a pressing concern for cities around the world. In recent months, cities like New York and London have also reported similar issues, highlighting the need for a coordinated global response.

Locally, the City of Copenhagen is working with organisations like the IT University of Copenhagen and the Copenhagen Business School to develop new strategies for detecting and preventing duplicate image replacement. Specific initiatives include the launch of a new AI-powered monitoring system on Østerbro's Nordre Frihavn, as well as a series of workshops and training sessions for city employees at the Copenhagen City Hall on Rådhuspladsen. Additionally, the city is partnering with private companies like Danske Bank and Maersk to develop new technologies and best practices for addressing this issue.

Comparing Copenhagen's Approach to Other Cities

According to a recent report by the International Council on Systems Engineering, Copenhagen's approach to duplicate image replacement is more comprehensive than that of similar cities like Stockholm and Berlin. For example, while Stockholm has implemented a city-wide ban on certain types of image replacement software, Copenhagen is taking a more nuanced approach, focusing on education and awareness-raising among city employees and residents. In terms of specific data, a study by the University of Copenhagen found that the city's duplicate image replacement rate has decreased by 25% over the past six months, compared to a 10% decrease in Stockholm and a 5% increase in Berlin.

Looking ahead, the City of Copenhagen is planning to launch a new public awareness campaign in August 2026, which will include a series of advertisements on the city's public transportation system, as well as a dedicated website with resources and information for residents and businesses. The campaign is expected to cost around 500,000 DKK, which is a significant investment for the city, but one that is seen as necessary to address the growing threat of duplicate image replacement. As the city continues to develop its approach to this issue, it will be important to monitor progress and adjust strategies as needed to stay ahead of this evolving threat.
