  • Methods and apparatus for provable backup confirmation for digital wallets using key shards
    Patent number: 12639705
    Abstract: An apparatus includes a custodial mechanism that receive, from each compute device from at a quorum, an encrypted shard associated with a private key of a digital wallet and a cryptographic proof. The encrypted shard can be generated using an encryption key for the compute device. The cryptographic proof indicates that the compute device can decrypt the encrypted shard using a decryption key associated with that compute device and without revealing a value of the private key for the digital wallet. The apparatus generates, for each compute device, a cryptographic proof verification based on the encrypted shard for that compute device and an encryption witness for the private key of the digital wallet. The cryptographic proof verification indicates that the set of shards decrypted from the set of encrypted shards can be combined to reconstruct the private key.
