Authentication apparatus and method, network system, recording medium and computer program
First Claim
1. An authentication apparatus that performs, when a user terminal used by a user assigned with predetermined user identification information accesses predetermined information, authentication as to whether the user terminal is valid based on terminal identification information assigned to each user terminal, said apparatus comprising:
- user identification information recording means recording the user identification information therein;
user identification information determination means for receiving from the user terminal the user identification information of the user using the user terminal, and comparing the received user identification information with user identification information recorded in the user identification information recording means so as to determine whether the received user identification information is valid;
terminal identification information generation means for, when the received user identification information is determined to be valid, generating the terminal identification information to be recorded in the user terminal, and transmitting the generated terminal identification information to the user terminal;
terminal identification information recording means for recording the terminal identification information;
authentication means for comparing the terminal identification information received when the user terminal accesses the predetermined information with the terminal identification information recorded in the terminal identification information recording means so as to determine whether the received terminal identification information is valid; and
allowing means for, when the received terminal identification information is valid, allowing the access from the user terminal.

Abstract
An authentication apparatus that makes it difficult to perform posing when accessing information is provided. When there is an access request from a mobile phone, an authentication server transmits a program to the mobile phone (S3202). The program is for reading data regarding an individual number (for example, serial number) recorded in a scratch pad of the mobile phone, and transmitting the data to the authentication server. The authentication server that receives the data regarding the serial number transmitted by activation of the program (S3202) compares the serial number with data regarding the identification number of each mobile phone, the data being maintained in the authentication server (S3203). When the serial number matches any of serial numbers maintained therein (S3203: Yes), the authentication server authenticates the access to be valid.

20. A network system, comprising:
-
a first server recording information accessible to a user terminal therein; and
an authentication apparatus performing authentication as to whether the user terminal that desires to access the information recorded in the first server is valid, the first server being configured to search for relevant information in response to an access from a valid user terminal and transmit the searched for information to the user terminal that is a source of the access;
the authentication apparatus including;
user identification information recording means recording therein predetermined user identification information assigned to a user;
user identification information determination means for receiving from the user terminal the user identification information of the user using the user terminal, and comparing the received user identification information with user identification information recorded in the user identification information recording means so as to determine whether the received user identification information is valid;
terminal identification information generation means for, when the received user identification information is determined to be valid, generating the terminal identification information to be recorded in the user terminal, and transmitting the generated terminal identification information to the user terminal;
terminal identification information recording means for recording the terminal identification information;
authentication means for comparing the terminal identification information received when the user terminal accesses the predetermined information with the terminal identification information recorded in the terminal identification information recording means so as to determine whether the received terminal identification information is valid; and
allowing means for, when the received terminal identification information is valid, allowing the access from the user terminal. - View Dependent Claims (21, 22, 23, 24, 25)

26. A network system, comprising:
-
means for enabling a first server recording information accessible to a user terminal to perform communications within a predetermined network; and
an authentication apparatus performing authentication as to whether a user terminal that desires to access the information via the network is valid, the first server being configured to search for relevant information in response to an access from a valid user terminal and transmit the searched for information to the user terminal that is a source of the access, the authentication apparatus comprising;
user identification information recording means recording the user identification information therein;
user identification information determination means for receiving from the user terminal the user identification information of the user using the user terminal, and comparing the received user identification information with user identification information recorded in the user identification information recording means so as to determine whether the received user identification information is valid;
terminal identification information generation means for, when the received user identification information is determined to be valid, generating the terminal identification information to be recorded in the user terminal, and transmitting the generated terminal identification information to the user terminal;
terminal identification information recording means for recording the terminal identification information;
authentication means for comparing the terminal identification information received when the user terminal accesses the predetermined information with the terminal identification information recorded in the terminal identification information recording means so as to determine whether the received terminal identification information is valid; and
allowing means for, when the received terminal identification information is valid, allowing the access from the user terminal.

27. A method of authenticating a user terminal in a network system,
wherein an authentication apparatus is provided in a network system in which a first server recording information accessible to a user terminal exists in a predetermined network, and the authentication apparatus performs authentication as to whether a user terminal that desires to access the information is valid, the authentication apparatus records user identification information assigned in advance to a user; -
receives from the user terminal requesting for authentication the user identification information of the user using the user terminal, and when the received user identification information matches any user identification information that is already recorded, determines that the user terminal is valid and generates terminal identification information to be recorded in the user terminal;
records and transmits the generated terminal identification information to the user terminal; and
compares the terminal identification information received when the user terminal accesses predetermined information with the terminal identification information recorded in the apparatus so as to determine whether the received terminal identification information is valid, and when the received terminal identification information is valid, allows the access from the user terminal.
