DISTRIBUTED LEDGER DATA VERIFICATION NETWORK

Abstract:

A system and method for verifying users are disclosed. The method includes receiving, by a server computer, from a first authorizing entity computer, an indication of a first hash of information about the user. The first authorizing entity computer has previously verified the user and stored the first hash in a first database. The server computer stores a location of the first hash in a location database. Then the server computer receives from a second authorizing entity computer a verification request message including a second hash of information about the user and retrieves the first hash from the first database using the location. The server computer compares the first hash to the second hash to determine if the hashes match. After determining that the hashes match, the server computer sends a verification response message to the second authorizing entity computer, indicating that the user was previously verified.
