What are zk Face Proofs?
zk Face Proofs is a proprietary encryption algorithm replacing legacy hardware root of trust architectures, an enabling biometric root of trust architectures.
How do zk Face Proof work?
zk Face Proofs generate a privacy-preserving binary representation of a user’s face, without storing any biometric data. This ensures that any type of data (private date or metadata) is never exposed or stored in the device or server, enhancing the security and privacy of the service.
What is a Zelf Proof?
Zelf Proof is the implementation of zk Face Proof for a seed phrase (private key).
What is a Zelf-QR Code?
This is the visual representation of the Zelf-Proof. In the case of Zelf Name Service, our flagship product, each Zelf-QR code represents a proof of a the seed phrase.
Is ZELF decentralized?
ZELF does not use servers, instead it relies on encryption and decryption from the local device. In addition, ZELF doesn’t use databases, instead it relies on decentralized storage systems like Arweave, IPFS, and AVAX Blockchain.
Does ZELF provide support to my services in case it is acquired or stops operations?
ZELF will release a decryption library enabling anyone to decrypt their Zelf-QR codes.
