Abstract

Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to file documents with an agency. In some scenarios, the documents may be associated with unclaimed property. The documents may be associated with a smart contract. Accordingly, the document may be encrypted using a public key for the smart contract and compiled into a block of the blockchain. In response to a request to provide access to the document to a particular node, the private key for the smart contract may be encrypted using the public key for the particular node and compiled into a block of the blockchain.

Claims (70)

1 . A computer-implemented method of providing access to confidential data stored in a blockchain relating to a plurality of smart contracts and maintained by a plurality of nodes, the method comprising:

detecting, by one or more processors, that a new smart contract has been created;

generating, by the one or more processors, a public key and a private key for the new smart contract;

publishing, to the blockchain, the public key for the new smart contract such that two or more of the plurality of nodes can (i) access the public key for the new smart contract and (ii) encrypt data associated with the new smart contract using the public key of the smart contract, the data associated with the new smart contract including a document to be filed with an agency;

compiling, by the one or more processors, the data associated with the new smart contract into a first block of the blockchain;

distributing, by the one or more processors, the first block to the plurality of nodes to form a consensus on a first update to the blockchain;

detecting, by the one or more processors, a request to provide access to the data associated with the new smart contract to a particular node of the blockchain, the request indicating the particular node;

generating, by the one or more processors, a transaction indicating (i) the private key for the new smart contract, the private key for the new smart contract being encrypted in based upon the public key for the particular node, and (ii) the particular node;

compiling, by the one or more processors, the transaction into a second block of transactions; and

distributing, by the one or more processors, the second block to the plurality of nodes to form a consensus on a second update to the blockchain.

2 . The computer-implemented method of claim 1 , wherein:

a portion of the plurality of smart contracts relate to a plurality of unclaimed property, and

the new smart contract relates to a particular unclaimed property.

3 . The computer-implemented method of claim 2 , wherein:

the data associated with the new smart contract indicates a jurisdiction associated with the particular unclaimed property, the jurisdiction corresponding to a filing deadline for reporting unclaimed property in the jurisdiction.

4 . The computer-implemented method of claim 3 , wherein:

the new smart contract directs the generation of the request to provide the agency with access to the document to be filed with the agency based upon the filing deadline for reporting unclaimed property in the jurisdiction.

5 . The computer-implemented method of claim 3 , wherein:

the data associated with the new smart contract indicates a last known address for a holder of the property.

6 . The computer-implemented method of claim 5 , wherein:

the new smart contract directs the sending of a notice to the last known address based upon the filing deadline for reporting unclaimed property in the jurisdiction.

7 . The computer-implemented method of claim 2 , wherein the document to be filed with the agency is an unclaimed property report.

8 . The computer-implemented method of claim 1 , wherein document to be filed with the agency is at least one of a policy form, an application form, or a rate change form.

9 . The computer implemented method of claim 8 , wherein the agency is a government insurance agency.

10 . The computer-implemented method of claim 1 , wherein generating the transaction further comprises:

applying, by the one or more processors, a digital signature to the transaction, the digital signature being generated based upon the private key for a node associated with the one or more processors.

11 . The computer-implemented method of claim 1 , wherein the first block and the second block are the same block.

12 . The computer-implemented method of claim 1 , wherein generating the transaction comprises:

determining, by the one or more processors, a permission level associated with the particular node; and

generating, by the one or more processors, the transaction when the permission level indicates that the particular node is permitted to access the document to be filed with the agency.

13 . The computer-implemented method of claim 1 , wherein detecting the request to provide access to the data further comprises:

receiving, at the one or more processors, the request from a requesting node;

determining, by the one or more processors, a permission level associated with the requesting node; and

generating, by the one or more processors, the transaction when the permission level indicates that the requesting node is permitted to request that other nodes receive access to document to be filed with the agency.

14 . The computer-implemented method of claim 1 , wherein detecting the request to provide access to the data further comprises:

generating, by the one or more processors, the request to provide access to the data associated upon being directed by the new smart contract.

15 . A computer system for providing access to confidential data stored in a blockchain relating to a plurality of smart contracts and maintained by a plurality of nodes, the computer system comprising:

one or more processors;

a communication module adapted to communicate with the 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;

generate a public key and a private key for the new smart contract;

publish, to the blockchain, the public key for the new smart contract such that two or more of the plurality of nodes can (i) access the public key for the new smart contract and (ii) encrypt data associated with the new smart contract using the public key of the smart contract, the data associated with the new smart contract including a document to be filed with an agency;

compile the data associated with the new smart contract into a first block of the blockchain;

distribute, via the communication module, the first block to a plurality of nodes to form a consensus on a first update to the blockchain;

detect a request to provide access to the data associated with the new smart contract to a particular node of the blockchain, the request indicating the particular node;

generate a transaction indicating (i) the private key for the new smart contract, the private key for the new smart contract being encrypted in based upon the public key for the particular node, and (ii) the particular node;

compile the transaction into a second block of transactions; and

distribute, via the communication module, the second block to the plurality of nodes to form a consensus on a second update to the blockchain.

16 . The computer system of claim 15 , wherein to generate the transaction, the instructions, when executed, cause the computer system to:

apply a digital signature to the transaction, the digital signature being generated based upon the private key for a node associated with the one or more processors.

17 . The computer system of claim 15 , wherein to generate the transaction, the instructions, when executed, cause the computer system to:

determine a permission level associated with the particular node; and

generate the transaction when the permission level indicates that the particular node is permitted to access the document to be filed with the agency.

18 . The computer system of claim 15 , wherein to detect the request to provide access to the data, the instructions, when executed, cause the computer system to:

receive the request from a requesting node;

19 . The computer system of claim 15 , wherein to detect the request to provide access to the data, the instructions, when executed, cause the computer system to:

generate the request to provide access to the data associated upon being directed by the new smart contract.

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