Publication number: 20240104241Abstract: A user agent stores user information of a user and user information provided to a service provider server. When a user terminal registers the user in the service provider server, the user agent sends the user information already provided to the service provider server to the user terminal. When the user agent receives a provision permission of the user information from the user terminal, the user agent generates pseudo user identification information, a public key, and a private key, signs a service document of the service provider server, and sends the service document to the service provider server via the user terminal. When the signed service document is received, the user agent verifies the signature and sends user information to the service provider server.Type: ApplicationFiled: December 15, 2020Publication date: March 28, 2024Inventors: Yoshihiko OMORI, Takao YAMASHITA, Yurika SUGA, Yasuhiko YOSHIMURA
