Information processing system, information processing method, and program

An information processing method performed by a first server and a second server, the method comprising:

• managing, by the first server, first authentication information for logging in to the first server with respect to a user
• managing, by the first server, user information of the user stored in a first storage, the first storage includes, for the user, a first storage area storing information regarding a first business operator, and a second storage area storing information regarding a second business operator;
• performing, by the first server, an account-opening task of the first business operator using the information stored in the first storage area;
• performing, by the first server, an account-opening task of the second business operator using the information stored in the second storage area,
• generating and transmitting, by the second server, an account-opening application for the first business operator when receiving, from a user terminal used by the user, an account-opening request of the first business operator, second authentication information for the user to log in to the second server;
• issuing and transmitting, by the first server, first authentication information for the user to the second server when receiving the account-opening application from the second server,
• storing, by the second server and when receiving the first authentication information of the user from the first server, the first authentication information of the user in a second storage in association with second authentication information of the user;
• acquiring, by the second server, the user information of the user from the user terminal;
• logging in to the first server, by the second server, using the first authentication information to cause the first server to perform the account-opening task of the first business operator;
• requesting, by the first server, the user information of the user necessary for performing the account-opening task of the first business operator from the second server when receiving the first authentication information from the second server;
• transmitting, by the second server, the user information of the user necessary for performing the account-opening task of the first business operator to the first server, when receiving a request from the first server;
• and
• storing, by the first server, the user information of the user necessary for performing the account-opening of the first business operator received from the second server, in the first storage area of the first storage.

A non-transitory computer-readable storage medium storing a program causing a first server and a second server to perform processing comprising:

• managing, by the first server, first authentication information for logging in to the first server with respect to a user
• managing, by the first server, user information of the user stored in a first storage, the first storage includes, for the user, a first storage area storing information regarding a first business operator, and a second storage area storing information regarding a second business operator;
• performing, by the first server, an account-opening task of the first business operator using the information stored in the first storage area;
• performing, by the first server, an account-opening task of the second business operator using the information stored in the second storage area, generating and transmitting, by the second server, an account-opening application for the first business operator when receiving, from a user terminal used by the user, an account-opening request of the first business operator, second authentication information for the user to log in to the second server;
• issuing and transmitting, by the first server, first authentication information for the user to the second server when receiving the account-opening application from the second server,
• storing, by the second server and when receiving the first authentication information of the user from the first server, the first authentication information of the user in a second storage in association with second authentication information of the user;
• acquiring, by the second server, the user information of the user from the user terminal;
• logging in to the first server, by the second server, using the first authentication information to cause the first server to perform the account-opening task of the first business operator;
• requesting, by the first server, the user information of the user necessary for performing the account-opening task of the first business operator from the second server when receiving the first authentication information from the second server;
• transmitting, by the second server, the user information of the user necessary for performing the account-opening task of the first business operator to the first server, when receiving a request from the first server;
• and
• storing, by the first server, the user information of the user necessary for performing the account-opening of the first business operator received from the second server, in the first storage area of the first storage.
