Systems and methods for controlled access to policy data on blockchain

A computer system for providing access to confidential data stored in a blockchain, the blockchain relating to a plurality of smart contracts, the computer system comprising:

• one or more processors;
• a communication module adapted to communicate with a plurality of nodes;
• a non-transitory program memory coupled to the one or more processors and storing executable instructions that, when executed by the one or more processors, cause the computer system to:
• detect that a new smart contract has been created for inclusion in the plurality of smart contracts;
• detect a request to provide a particular node access to encrypted data associated with the new smart contract, the request indicating the particular node;
• determine that a permission level associated with the particular node indicates that the particular node is permitted to access information associated with an insurance policy;
• in response to the determination, generate a transaction indicating (i) a private key for the new smart contract, the private key for the new smart contract being encrypted using a public key for the particular node, and (ii) an identity of the particular node;
• apply a digital signature to the transaction, the digital signature being generated based upon a second private key for a node associated with the one or more processors;
• compile the transaction into a block of transactions;
• and
• distribute, via the communication module, the block to the plurality of nodes to form a consensus on an update to the blockchain.

A non-transitory computer readable storage medium storing processor-executable instructions, that, when executed, cause one or more processors to:

• detect that a new smart contract has been created;
• detect a request to provide a particular node access to encrypted data associated with the new smart contract, the request indicating the particular node;
• determine that a permission level associated with the particular node indicates that the particular node is permitted to access information associated with an insurance policy;
• in response to the determination, generate a transaction indicating (i) a private key for the new smart contract, the private key for the new smart contract being encrypted using a public key for the particular node, and (ii) an identity of the particular node;

• compile the transaction into a block of transactions;
• and
• distribute the block to the plurality of nodes to form a consensus on an update to the blockchain.

A computer-implemented method of providing access to confidential data stored in a blockchain, the blockchain relating to a plurality of smart contracts, the method comprising:

• detecting, by one or more processors, that a new smart contract has been created for inclusion in the plurality of smart contracts;
• receiving, by the one or more processors, a request from a requesting node to provide a particular node access to encrypted data associated with the new smart contract, the request indicating the particular node;
• determining, by the one or more processors, that a permission level associated with the requesting node indicates that the requesting node is permitted to request that other nodes receive access to information associated with an insurance policy;
• in response to the determination, generating, by the one or more processors, a transaction indicating (i) a private key for the new smart contract, the private key for the new smart contract being encrypted using a public key for the particular node, and (ii) an identity of the particular node;
• applying, by the one or more processors, a digital signature of a node associated with the one or more processors to the transaction, the digital signature being generated based upon a second private key for a node associated with the one or more processors;
• compiling, by the one or more processors, the transaction into a block of transactions;
• and
• distributing, by the one or more processors, the block to the plurality of nodes to form a consensus on an update to the blockchain.
