Origin Lens: A Privacy-First Mobile Framework for Cryptographic Image Provenance and AI Detection
This addresses visual disinformation for end-users by providing a privacy-focused verification tool, though it appears incremental as it builds on existing detection and provenance methods.
The paper tackles the problem of verifying image authenticity and detecting AI-generated content in the face of generative AI proliferation, presenting Origin Lens, a privacy-first mobile framework that performs cryptographic image provenance verification and AI detection locally on device, with results including graded confidence indicators for users.
The proliferation of generative AI poses challenges for information integrity assurance, requiring systems that connect model governance with end-user verification. We present Origin Lens, a privacy-first mobile framework that targets visual disinformation through a layered verification architecture. Unlike server-side detection systems, Origin Lens performs cryptographic image provenance verification and AI detection locally on the device via a Rust/Flutter hybrid architecture. Our system integrates multiple signals - including cryptographic provenance, generative model fingerprints, and optional retrieval-augmented verification - to provide users with graded confidence indicators at the point of consumption. We discuss the framework's alignment with regulatory requirements (EU AI Act, DSA) and its role in verification infrastructure that complements platform-level mechanisms.
