Privasea

Privasea develops proof-of-human technology using fully homomorphic encryption (FHE) to validate human liveness through facial biometrics without compromising personal data. The company's flagship product, FheID, is a proof-of-human application that attests user human liveness to protect digital presence from bots and AI impersonations across Web3 and Web2 platforms. Using the FheID app, users verify their human likeness through their phone's camera, with biometric data transformed into encrypted vectors directly on the device using the user's client key before being sent to Privasea's fortified servers. This process ensures original biometric data remains confidential even from Privasea itself, as the encrypted vectors cannot be reverse-engineered to reveal personal information such as name, email, or sensitive biometric details. Upon verification, users generate unique NFTs that serve as personalized proof of human identity, enabling access to services, airdrops, and rewards across various applications. Privasea also operates DeepSea, an AI network powered by real humans that supports decentralized AI agents, and offers the ImHuman Telegram mini-app for bot detection. The platform includes a Node and Heart Combo system for Privasea network node operators and FHE compute power contributors, along with StarFuel NFTs that boost network participation and grant special access to Privasea DApps including proof-of-human features. The technology addresses the growing challenge of distinguishing real humans from AI bots and impersonators in digital environments, with applications in social mining, airdrop verification, and platform security.
