ABSTRACT:
A data distribution apparatus installed in a data center transmits data to a data acquisition apparatus installed in a store via a communication network. The data acquisition apparatus receives authentication information, such as the fingerprint, ID card or the like of a user, for user authentication, and the data distribution apparatus authenticates the user according to the authentication method selected from among multiple authentication methods and corresponding to the authentication information received by the data acquisition apparatus. The data distribution apparatus transmits data changed in format according to the authentication method used to the data acquisition apparatus. In the case of an authentication method being high in security, data is made changeable, and in the case of an authentication method being lower in security, data is changed so as to have an unchangeable format, whereby the unauthorized use of data is prevented.
