Service providing system and data providing method

A system implemented by one or more information processing apparatuses and providing a service to a service receiving apparatus connected via a network to the system, the system comprising:

• a management information storage that stores management information including service identification information of the service, user authentication information of a user using the service, and device authentication information of the service receiving apparatus that are associated with each other;
• an authentication information receiving unit that receives, as authentication information, at least one of user authentication information used for user authentication and device authentication information used for device authentication from the service receiving apparatus;
• an authentication unit that performs authentication by referring to the management information storage based on the received authentication information;
• an obtaining unit that obtains process target data from an external service based on an entry request from the service receiving apparatus that has been successfully authenticated;
• and
• a conversion unit that converts the obtained process target data into output data with a data format that the service receiving apparatus is able to output.
