William Baxter is an inventor based in Boston, Massachusetts, associated with Fmr Corp. His patent work addresses secure backup and recovery of wallet private keys, combining encryption with distributed PIN-shard storage.

Latest Patents

Baxter 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 request specifying a wallet private key, a backup-server identifier, a PIN-shard fracture scheme, and multiple PIN-shard backup devices. A user security PIN encrypts the wallet private key, which is then encrypted again using a symmetric key calculated from the backup server’s associated public key and an app private key. The twice-encrypted key is sent to a private-key backup server. The system also encrypts the user PIN with an asymmetric keypair, creates encrypted PIN shards, and sends those shards to designated backup devices.

Career Highlights

Baxter’s listed patent focuses on protecting wallet credentials through layered encryption and distributed PIN-shard backups. The approach separates key storage from PIN recovery components, supporting a structured process for backing up and recovering wallet keys.

Collaborations

Baxter is associated with Fmr Corp. His listed coworkers include David Lawrence Hill and Jason Thomas Ward.

Conclusion

William Baxter’s patent describes a layered security system for wallet-key backup and recovery, combining encryption with distributed PIN-shard storage.
