Method and System for Blockchain-Based Combined Identity, Ownership, Integrity and Custody Management

A system for issuing blockchain-based digital certificates comprising:

• a processor;
• a data store positioned in communication with the processor;
• and
• a network communication device positioned in communication with each of the processor, the data store, and a network;
• wherein the network communication device is operable to receive from a user hashed user identification information, object information, and a user public key;
• wherein the processor is operable to record to a digital certificate smart contract deployed at a digital certificate smart contract address on a blockchain network the hashed user identification information and object information and a timestamp of when the hashed user identification information and the object information were received, defined as a received timestamp;
• wherein the processor is operable to sign the digital certificate smart contract with an issuer signature;
• wherein the system is operable to perform a user identity verification process to confirm a user identity, comprising:
• the network communication device obtaining each of a sealed user record address, a sealed verification record address, and a token from a user certification record address at the user certification record address;
• the network communication device retrieving hashed user identification information from a sealed user record at the sealed user record address, defining retrieved user identification information;
• the processor decrypting the received user identification information using the user public key, defining decrypted user identification information;
• the processor comparing the decrypted user identification information with the retrieved user identification information;
• the network communication device retrieving a hashed verification record from a sealed verification record at the sealed verification record address, defining a retrieved verification record;
• the processor determining if the token from the user certification record address is valid;
• upon determining the token from the user certification record address is valid, the processor generating a generated verification record comprising the retrieved user identification information and the token;
• the processor generating a hashed verification record by applying a hash function to the generated verification record;
• the processor comparing the hashed verification record with the retrieved verification record;
• and
• the processor confirming a user identity by determining the decrypted user identification information and the retrieved user identification information are at least a partial match and the hashed verification record and the retrieved verification record are at least a partial match;
• wherein the processor is operable to, upon the user identity being confirmed, generate a combination certificate configured to be shared by the user to verify the user's ownership of an object associated with the object information;
• wherein the network communication device is operable to send the combination certificate to the user;
• wherein network communication device is operable to receive hashed second user identification information associated with a second user and a derivative of the object information, defining a derivative object information;
• wherein the processor is operable to record to a second digital certificate smart contract deployed at a second digital certificate smart contract address on a second blockchain network the hashed second user identification information and the derivative object information and a timestamp of when the hashed second user identification information and the derivative object information were received, defined as a received timestamp;
• wherein the processor is operable to sign the second digital certificate smart contract with a second issuer signature;
• wherein the processor is operable to generate a second combination certificate configured to be shared by the second user to verify the second user's ownership of a derivative object associated with the derivative object information;
• and
• wherein the network communication device is operable to send the second combination certificate to the second user.
