Latest Patents

Hill is credited with 1 patent: “End-to-End Encryption and Hot Wallet Key Recovery Apparatuses, Processes and Systems.” The invention processes key-backup and key-recovery requests to produce corresponding responses. It obtains a wallet private key, a backup-server identifier, a PIN-shard scheme, and designated backup devices. A user security PIN encrypts the wallet private key, which is then encrypted again using a symmetric key derived from the backup server’s public key and an app private key. The twice-encrypted key is sent to the backup server. The system also encrypts the PIN using an asymmetric keypair, creates encrypted PIN shards, and sends those shards to designated backup devices.
