<P>PROBLEM TO BE SOLVED: To perform a securities transaction by keeping safety in a securities brokerage transaction. <P>SOLUTION: When a log-in request to a securities server 400 is received from a customer terminal 200, a bank server 300 generates log-in information, including log-in route information "0" indicating log-in via the bank server 300 and a log-in ID, and transmits the log-in information to the securities server 400. When there is a trouble with the bank server 300, the customer terminal 200 transmits the log-in information, including the log-in route information "1" indicating the log-in not via the bank server 300, as a direct log-in request to the securities server 400. The securities server 400 performs authentication processing, based on first log-in route information and the log-in ID for the log-in information received via an exclusive line 130, and performs authentication processing, based on whether second log-in route information is included or not, for the log-in information directly received via a network 140. <P>COPYRIGHT: (C)2009,JPO&INPIT |
