'My Grandfather's Face Was Replaced by a Stranger': Istanbul Residents Confront the Spread of AI-Generated Duplicate Images

The photograph had hung in the Fener-Balat Cultural Heritage Archive for eleven years. Then, in May, a volunteer cataloguer noticed something wrong: the original scan of a 1960s street scene from Vodina Caddesi had been replaced on the archive's shared digital repository with a near-identical AI-generated version, the faces subtly smoothed, a minaret in the background slightly repositioned. The original was gone. No one has claimed responsibility.

The incident is not isolated. Across Istanbul, community groups, municipal cultural offices, and individual families are confronting a problem that has accelerated sharply in 2026: the proliferation of algorithmically duplicated or substituted images in shared digital spaces, quietly displacing authentic visual records. The issue has gathered urgency here partly because Istanbul's photographic heritage carries unusual civic weight — images of neighbourhoods like Tarlabaşı, Sultanahmet, and the Princes' Islands serve as evidence in ongoing disputes over demolition permits, heritage listing applications, and even court cases tied to the city's seismic retrofit programme following the 2023 Kahramanmaraş earthquakes.

Communities Describe the Discovery

In Kadıköy, the Moda Neighbourhood Solidarity Platform — a resident-run group operating out of a rented space on Moda Caddesi — began documenting complaints in March 2026 after members noticed that images submitted to a shared municipal planning portal appeared to have been processed and returned with altered details. Doorways had changed. Facade cracks that residents had photographed as evidence for structural assessments looked, in the returned versions, repaired or absent.

The Syrian community in Bağcılar, where an estimated 120,000 Syrian nationals are registered according to Istanbul Metropolitan Municipality figures from 2024, faces a particular vulnerability. Many families hold digital scans of identity documents and personal photographs as their primary record of pre-war lives. Community liaison workers at the Bağcılar Integration and Support Centre have reported that several families discovered scans uploaded to document-processing platforms had been returned as visually altered files — backgrounds changed, faces slightly resharpened in ways that made document verification harder, not easier.

The Çengelköy Cultural Association, which maintains a neighbourhood photograph archive stretching back to the 1940s, sent a formal complaint to the Istanbul Directorate of Culture and Tourism in April 2026 after finding duplicate, AI-modified versions of twelve archive images circulating on a commercial image licensing platform without attribution. The association's collection is not subject to any commercial licensing agreement.

Why the Problem Is Harder to Solve Than It Looks

Tracking duplicate or replaced images is technically demanding and expensive. Forensic image authentication tools capable of detecting AI-generated substitutions cost upward of 15,000 Turkish lira per annual licence — a figure that puts them well beyond the budgets of most neighbourhood associations. Istanbul's municipal digital infrastructure, managed through the İBB Bilgi İşlem Dairesi, has no publicly confirmed programme for systematic image-integrity verification as of this month.

The timing matters. Turkey's Personal Data Protection Authority, known as KVKK, updated its guidance on biometric data in late 2025, but enforcement specific to AI-generated image substitution remains undefined. Community advocates are watching a draft amendment to the Turkish Intellectual and Artistic Works Law, currently in committee at the Grand National Assembly, which would for the first time create a legal category for algorithmically derived copies of protected images. Its passage date has not been announced.

For residents, the practical advice from digital rights advocates is blunt: watermark originals before uploading anywhere, maintain offline backups on physical media, and use cryptographic hash verification — essentially a digital fingerprint — to confirm that any image retrieved from a shared platform matches the file originally submitted. The Bilgi University Digital Rights Clinic in Dolapdere has offered free workshops on exactly these techniques, with the next session scheduled for July 19 at the university's Santral Istanbul campus. Registration is open through the clinic's website. For those whose archives have already been compromised, the clinic advises filing a formal complaint with KVKK, citing Article 12 of the Personal Data Protection Law, before any further uploads are made.
