Abstract

A method and apparatus for transferring encrypted information to a database. First certification information is transferred from a first database to a second database. Second certification information is then transferred from the second database to the first database, where both the first certification information and the second certification information is authenticated. If both certifications are authenticated, the transfer of the encrypted information to the second database is enabled.
