About LumeFinder

LumeFinder is a Hong Kong-headquartered technology innovator specializing in comprehensive copyright solutions for AI-generated visual content, spanning images, videos, and digital art.

Amid the global AIGC boom, creators and enterprises face escalating challenges: ambiguous ownership attribution, cumbersome content traceability, and inefficient rights protection. To address these pain points, we integrate cutting-edge technologies—including blockchain timestamping, imperceptible digital watermarking, AI-powered content similarity detection, and IPFS decentralized storage—to build a trusted copyright ecosystem. Our proprietary solution embeds unique, attack-resistant watermarks and hash fingerprints at the moment of content generation, linking works to creators’ credentials, generation parameters, and timestamps on the blockchain for immutable proof.

Our one-stop service covers the full copyright lifecycle: instant certification for AI creations, real-time global infringement monitoring with automated evidence collection, and transparent transactions enabled by smart contracts for royalty distribution. Rooted in Hong Kong’s robust IP legal framework and supportive tech ecosystem, we cater to individual creators, creative studios, advertising agencies, and AIGC platforms worldwide.

Guided by our mission to "Make every AIGC creation traceable, protected, and valuable", LumeFinder empowers users to safeguard their intellectual property, ensure compliant commercial use, and unlock the full commercial potential of their AI-generated works.
