- YumeProof uses IOTA’s tangle and Google Play Integrity API to verify image authenticity instantly at capture.
- The app was developed by winners of the IOTA Malaysia Hackathon held in July 2025.
The first practical application tackling manipulated and AI-generated images has emerged with YumeProof, a project that leverages IOTA’s tangle technology to prove the authenticity of photos in real time.
#IOTA is the perfect fit to tackle a problem I highlighted 3 months ago: the growing flood of fake photos, AI-generated images, and manipulated media fueling misinformation. 📸🛡️
Now the first real-world app is here: @YumeProof – winners of the IOTA Malaysia Hackathon (July… https://t.co/kLwX3lfXGI

YumeProof Combines IOTA’s Tangle and Hardware Attestation for Secure Image Verification
YumeProof integrates the IOTA’s tangle to anchor immutable proofs of image data, paired with hardware attestation through Google’s Play Integrity API.
This combination allows images to be cryptographically signed at the moment of capture by a verified device, making any tampering or manipulation instantly detectable.
The system relies on the distributed ledger’s immutability to provide an unalterable record of the image’s origin and capture details.
The hardware attestation ensures that the device producing the image is genuine and has not been compromised, significantly reducing the risk of falsified media entering the ecosystem.
IOTA Malaysia Hackathon Winners Deliver Practical Tool Against Deepfakes and Misinformation
YumeProof was developed by the winning team of the IOTA Malaysia Hackathon held in July 2025, marking a significant milestone in real-world blockchain application for media verification.
The app addresses a pressing issue in digital content integrity, where AI-generated images and deepfakes contribute to misinformation and public distrust.
The platform aims to support sectors like journalism, forensic analysis, and public communication by providing a verifiable chain of custody for digital images.
This approach creates a new standard for digital media authentication, leveraging cryptographic methods and blockchain anchoring to increase transparency and trustworthiness in digital content.
