Abstract
A method for creating and registering the authentication information is provided. The method includes steps of: (a) an intermediate server determining whether the specific user's public key is registered if (i) the specific user's public key and (ii) a hash value of the specific user's information or its processed value are acquired from the biometric authentication server which received a request for registration of authentication information; and (b) the intermediate server, if the specific user's public key is determined to be unregistered and at least one certain anchoring condition is satisfied, registering with a database a representative hash value or its processed value in a certain data structure, wherein the representative hash value is created by using (1) a specific hash value and (2) at least one hash value of at least one neighboring node which corresponds to a node of the specific hash value.
