Method and system for identity and access management for blockchain interoperability

A method performed by a computerized device of generating wallets for discrete blockchain networks comprising:

• receiving a primary seed comprising of a parent public key, a parent private key, and a parent chain code at the computerized device;
• generating an enhanced hierarchical deterministic wallet at the computerized device by applying a CKD function to the primary seed and deriving an enhanced parent public key and an enhanced parent private key at the computerized device;
• receiving a first secondary seed comprising of a parent public key, a parent private key, and a parent chain code at the computerized device;
• generating a first toughened hierarchical deterministic wallet at the computerized device, comprising:
• deriving a first toughened parent public key and a first toughened parent private key by applying a CKD function to the first secondary seed;
• deriving a first toughened primary child public key by applying a CKD function to a combination of the first toughened parent public key, a first parent chain code, and the enhanced parent public key;
• deriving a first toughened primary child private key by applying a CKD function to a combination of the first toughened parent private key, the first parent chain code, and the enhanced parent private key;
• and
• generating a first seal contract comprising hashed user data related to a user;
• deploying the first seal contract on an user identity management blockchain, the transaction deploying the first seal contract being signed by the first toughened primary child private key of the first toughened hierarchical deterministic wallet;
• receiving an access request from a certification authority for the first seal contract to verify an identity of the user;
• sharing the data comprised by the first seal contract with the certification authority to verify the identity of the user;
• receiving a second secondary seed comprising a parent public key, a parent private key, and a parent chain code at the computerized device;
• and
• generating a second toughened hierarchical deterministic wallet at the computerized device, comprising:
• deriving a first toughened parent public key and a first toughened parent private key by applying a CKD function to the second secondary seed;
• deriving a first toughened primary child public key that is non- equivalent to the first toughened primary child public key of the first toughened hierarchical deterministic wallet by applying a CKD function to a combination of the first toughened parent public key of the second toughened hierarchical deterministic wallet, a first parent chain code of the first toughened parent public key of the second toughened hierarchical deterministic wallet, and the enhanced parent public key;
• deriving a first toughened primary child private key that is non-equivalent to the first toughened primary child private key of the first toughened hierarchical deterministic wallet by applying a CKD function to a combination of the first toughened parent private key of the second toughened hierarchical deterministic wallet, a second parent chain code of the first toughened parent private key of the second toughened hierarchical deterministic wallet, and the enhanced parent private key;
• generating a second seal contract comprising hashed user data related to the user;
• and
• deploying the second seal contract on the user identity management blockchain, the transaction deploying the second seal contract being signed by the first toughened primary child private key of the second toughened hierarchical deterministic wallet
