<P>PROBLEM TO BE SOLVED: To provide an efficient network service. <P>SOLUTION: In a workflow (B), authentication processing (step S111) of a user for a series of applications of presence, content distribution, and log management, authentication determination processing (step S112) for determining whether the user is permitted to execute presence and log management, presence (step S113), and authentication determination processing (step S114) for determining whether the user is permitted to execute content distribution, content distribution (step S115), and log management (step S116) are executed in response to acceptance of a user request. That is, authentication processing is integrated into once before execution of the series of applications. Consequently, an authentication server which executes authentication processing is accessed once in the workflow (B) while it is accessed three times in a workflow (A) in the prior art. <P>COPYRIGHT: (C)2010,JPO&INPIT |
