A method comprising: receiving (S108), by a server computer , from a first authorizing entity computer : an indication of a first hash of information about the user, including a location of the first hash in a first database ; and an identifier of the user, wherein the user or information about the user has been verified by the first authorizing entity computer ; storing, by the server computer , the identifier of the user and the location of the first hash in a location database , the first database being separate and distinct from the location database ; receiving (S114), by the server computer , from a second authorizing entity computer , a verification request message about the user, the verification request message comprising a second hash of information about the user and the identifier of the user; retrieving (S116), by the server computer , the location of the first hash from the location database based on the identifier of the user; retrieving (S118), by the server computer , the first hash from the first database using the retrieved location of the first hash; comparing (S120), by the server computer , the first hash to the second hash to determine if the first hash and the second hash match; determining (S122), by the server computer , that the first hash and the second hash match; and responsive to determining that the first hash and the second hash match, sending, by the server computer , a verification response message to the second authorizing entity computer , the verification response message comprising verification data that the user was previously verified. receiving (S108), by a server computer , from a first authorizing entity computer : an indication of a first hash of information about the user, including a location of the first hash in a first database ; and an identifier of the user, wherein the user or information about the user has been verified by the first authorizing entity computer ; an indication of a first hash of information about the user, including a location of the first hash in a first database ; and an identifier of the user, wherein the user or information about the user has been verified by the first authorizing entity computer ; storing, by the server computer , the identifier of the user and the location of the first hash in a location database , the first database being separate and distinct from the location database ; receiving (S114), by the server computer , from a second authorizing entity computer , a verification request message about the user, the verification request message comprising a second hash of information about the user and the identifier of the user; retrieving (S116), by the server computer , the location of the first hash from the location database based on the identifier of the user; retrieving (S118), by the server computer , the first hash from the first database using the retrieved location of the first hash; comparing (S120), by the server computer , the first hash to the second hash to determine if the first hash and the second hash match; determining (S122), by the server computer , that the first hash and the second hash match; and responsive to determining that the first hash and the second hash match, sending, by the server computer , a verification response message to the second authorizing entity computer , the verification response message comprising verification data that the user was previously verified. <EOS>
