Title: Method and system for secure data record distribution using blockchain
IPC: G06F21/64
Filed: 2022-02-18
Abstract: PROBLEM TO BE SOLVED: To enhance the security of a data record distribution process. 
     SOLUTION: In the method, each group has a private-public key pair, but nodes only have a key share of their corresponding private key and no node has a full private key. Using threshold signature scheme, secret share joining and stealth addresses, data records from the input nodes are pooled at a stealth address determined through collaborative action of the input nodes, requiring cooperative determination of their public key, a shared secret, and the stealth address. The public key is copied into the transaction. The output nodes locate the transaction and extract the public key, cooperatively verify its authenticity, and collaboratively determine the shared secret. Then, the output nodes may collectively sign a second transaction for distributing data records from the stealth address to the output addresses.
