The present invention omits re-authentication by a user when streaming using a token is restarted after interruption of the streaming, and allows the streaming to be immediately restarted. This authentication server authenticates, for the purpose of streaming content provided by a content server, a user of a user terminal to execute said streaming, and is provided with: an authentication means that, if an authentication request for streaming content specified by a first user among a plurality of users is received from a user terminal used by the first user, compares information included in the authentication request with user registration information to authenticate the first user; a generating means that generates a first token indicating that the first user is an authenticated user if the authentication succeeded; and a communication means that transmits the generated first token to the user terminal. |
