Lantern Chrome extension security report

Lantern Glass is an innovative browser extension designed to bring transparency and trust to the world of digital art by verifying the provenance and ownership of artworks across popular art and social platforms. Whether you are an artist looking to prove ownership, a collector wanting to confirm authenticity, or a community member aiming to combat art fraud, Lantern Glass integrates seamlessly into your browsing experience to provide instant, reliable verification of digital art registered on the blockchain. By automatically scanning web pages on major platforms like Twitter (X), Pixiv, DeviantArt, ArtStation, Instagram, and Lantern’s own Glass portal, Lantern Glass detects embedded or linked unique Lantern ID codes associated with registered artworks. These IDs connect to a tamper-proof registry maintained on the Base blockchain, reflecting verified creators and provenance data. Once detected, the extension queries Lantern’s secure API to retrieve verification statuses and detailed provenance metadata. Then, it injects unobtrusive badge icons directly alongside the artworks or posts, indicating the art’s current status: Verified Creator, Unverified Creator, Disputed, Revoked, Chain Review Needed, Mismatch, or Error. Users can click on these badges to access full provenance details, including creator identity, linked platform accounts, registration timestamps, and on-chain authenticity information. Lantern Glass goes beyond simple badge display by cross-referencing the author of the page or posting user with the registered creator’s verified platform accounts. This cross-check enhances confidence in attribution and helps identify potential misattributions or fraudulent reposts. Additionally, through a context-menu option, users can right-click any image on supported sites and select “Verify with Lantern” to perform an on-demand lookup of its blockchain registration. The extension is designed to be lightweight and respectful of user experience. Its intelligent content scanning strategy ensures that only relevant elements are processed, minimizing impact on page performance and appearance. Users have full control over which platforms to enable or disable verification services via a dedicated options panel, tailoring the extension’s activity to their preferences. Caching mechanisms keep verification queries efficient by storing results locally for up to an hour, which reduces network overhead and speeds up badge rendering during browsing sessions. Security and privacy are fundamental to Lantern Glass’s design. The extension exclusively communicates with Lantern’s official API endpoints for verification data; it does not collect or transmit browsing history, personal information, or track users across different sites. Data gathered for verification is handled securely, and no information is sold or shared with third parties, ensuring the user’s privacy is fully protected. In essence, Lantern Glass acts as a trusted digital provenance verifier embedded right in your browser. It creates a safer, more transparent environment for engaging with digital art online, empowering communities to recognize genuine artworks and legitimate creators while curtailing fraud and misrepresentation.
