Abstract
Authorized persons are recognized based on unique identifiers allocated to the authorized persons and biological information of the authorized persons and a database of identifiers and biological information of authorized persons. When a person provides his identifier, biological information corresponding to the provided identifier is retrieved from the database and writing in a storage unit. Then, when the person provides his biological information, it is checked whether provided biological information matches with the biological information in the storage unit. When the two match, the person is recognized as an authorized person.
