The client terminal transmits first information to a second server, receives a digital signature from the second server, and transmits the digital signature together with the first information to the server apparatus. The second server generates the digital signature based on the first information. The server apparatus includes a controller configured to receive the first information and the digital signature from the client terminal, determine whether or not the first information is valid based on the first information and the digital signature received; and, transmit second information to the client terminal when the first information is valid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Server apparatus, client terminal, information processing system and information processing method","description":"A server apparatus is capable of communicating with a client terminal.
