Milan Leads Europe on Duplicate Image Crackdown — But Rivals Are Closing the Gap

Milan's major cultural and commercial institutions are moving faster than most European peers to identify and remove duplicate and AI-generated images from their digital archives — but the gap is narrowing, and some rivals have structural advantages the city has not yet matched. The push has become urgent in 2026, with the Milan-Cortina Winter Olympics less than six months out and the city's luxury and design sectors under intensifying scrutiny over the authenticity of their online marketing libraries.

The problem is specific and costly. Duplicate images — whether lifted from competing archives, generated by AI tools and uploaded as original assets, or simply re-tagged versions of existing files — inflate catalogue sizes, create intellectual property disputes, and erode trust with international licensing partners. For a city whose economy is substantially tied to the perceived uniqueness of its design and fashion output, the reputational stakes are unusually high.

What Milan Is Actually Doing

The Biblioteca Nazionale Braidense on Via Brera, which holds one of Italy's largest photographic and manuscript collections, began a systematic deduplication audit of its digitised holdings in early 2025, contracting Milan-based technology firm Avanade Italia to run perceptual hashing checks across roughly 2.3 million digital files. The process, which is ongoing, had cleared approximately 60 percent of the archive by June 2026 according to the institution's published project timeline. Separately, Camera Nazionale della Moda Italiana, which represents the country's fashion industry and is headquartered in the city, updated its digital asset management guidelines in March 2026, formally requiring member brands to certify original provenance for images submitted to shared commercial databases.

In Porta Nuova, where several global fashion and design companies maintain their Italian headquarters, the move toward centralised digital asset platforms has accelerated. Firms clustered in the Varesine district have increasingly adopted tools built on perceptual hash matching — a technique that identifies near-identical images even when file names, metadata, or colour profiles have been altered — rather than relying on manual review teams alone.

The Comune di Milano's own digital services directorate published a tender in February 2026 for a contract covering deduplication and metadata standardisation across its municipal image libraries, with an estimated value of €480,000. The contract was awarded in May. That municipal commitment marks a meaningful step; as recently as 2023, the city had no formal policy addressing image duplication in public-sector digital collections.

How Milan Compares to Paris, Amsterdam and Barcelona

The comparison with other European cities is instructive and, for Milan, not entirely flattering. Paris's Bibliothèque nationale de France completed a comparable deduplication project for its Gallica digital platform in 2024, covering more than 7 million digitised items and underpinned by a dedicated €1.2 million allocation under the French national digitisation strategy. Amsterdam's Rijksmuseum, operating under Dutch cultural ministry guidelines introduced in 2023, uses open-source image fingerprinting tools and publishes its deduplication methodology publicly — an approach that has drawn international interest and that Milan's institutions have not yet matched in transparency. Barcelona's Institut de Cultura de Barcelona adopted AI-assisted image verification as part of its Smart City programme in late 2024, integrating it with the city's broader data governance framework.

Milan's private sector is arguably ahead of its public institutions, driven by commercial necessity and the legal pressure of international licensing agreements. But the city lacks the kind of cross-sector coordination body that Amsterdam and Barcelona have built — a single standards-setting authority that bridges municipal archives, cultural institutions, and commercial operators. Camera Nazionale della Moda's March guidelines are a partial substitute, but their remit covers only fashion industry participants.

For businesses and cultural organisations operating in Milan now, the practical picture is this: compliance with Camera Nazionale della Moda's new provenance certification rules is expected ahead of the autumn fashion season in September 2026. Institutions tendering for Olympic-related digital projects should expect deduplication and image-provenance requirements in contract specifications, given the visibility attached to Milan-Cortina. And the municipal tender already awarded means the Comune itself will be running a cleaner, certified image library by the fourth quarter of this year — setting a benchmark that independent cultural venues from the Fondazione Prada to smaller Navigli-district galleries will face pressure to meet.
