Abstract:
A central service provider manages and writes transaction details to a private block chain network. Blocks of transaction records written onto the block chain by the central service provider are distributed to members of the block chain, thereby enabling data resiliency and self-verifiability. As the full block chain is available to members of the block chain network, the central service provider also ensures the privacy of transaction details by providing an assembled header and encrypted block of transaction records that are generated using a combination of symmetric and asymmetric cryptographic techniques. Altogether, the full block chain network is distributed across members of the block chain, but the members can only access and read transaction details in the block chain that they are authorized to view.

Claim (Index 1):
A method comprising:\n generating a symmetric key for a first party; encrypting the symmetric key to generate a first asymmetrically-encrypted key using a first public key assigned to the first party; encrypting the symmetric key to generate a second asymmetrically-encrypted key using a second public key assigned to a second member; receiving details for each of a set of transactions involving the first party; encrypting details of each of the transactions in the set of transactions using the symmetric key; generating a header comprising the first asymmetrically-encrypted key and the second asymmetrically-encrypted key; generating a block of transaction records corresponding to the received transactions, the block of transaction records comprising the encrypted details of the transactions; transmitting the header and the block of transaction records to a client device of the first party, the client device of the first party configured to access the transmitted header to decrypt the encrypted details of the transactions using a private key assigned to the first party; and transmitting the header and the block of transaction records to a client device of the second member, the client device of the second member configured to access the transmitted header to decrypt the encrypted details of the transactions using a private key assigned to the second member.
