When a user attempts to execute a procedure for transfer or the like from an app, user authentication is first required by a PIN code or the like. When the user authentication is successful, function limitation of an IC chip is released and a mode in which a function provided by the IC chip can be used is set. The app encrypts a procedure message describing procedure content with a private key using the function of the IC chip and creates an electronic signature. When the electronic signature and the procedure message are sent to an online service server, the server verifies the electronic signature using the corresponding electronic certificate. When the procedure message is sent from a valid user and it is confirmed as a result of the verification that the content is not altered, the server executes the procedure for transfer or the like in accordance with the content of the procedure message.

Online service providing system and application program

When a user activates an app, user authentication by a PIN code or the like is first executed. When the user authentication is successful (that is, when it is confirmed that a party operating the app is a user), function limitation of the IC chip is released and a mode in which a function provided by the IC chip can be used is set. The app creates an electronic signature with a private key using the function of the IC chip. When the electronic signature and the user ID are sent to a server of an online service, the server verifies the electronic signature using the corresponding electronic certificate. When the user ID is confirmed to be a user ID sent from a valid user, the user is permitted to use the online service.

The app encrypts a procedure message describing procedure content with a private key using the function of the IC chip and creates electronic signature. The electronic signature and the procedure message are transmitted to a server of an online service via an intermediate server. The server executes a procedure of transfer or the like in accordance with the content of the procedure message.

A power steering driving deviceincludes an input shaftprovided with a serrationand connected to an input mechanismlinked to a steering handle, an output shaftprovided with a serrationand connected to an output mechanismlinked to a vehicle wheel, and a torsion barthat connects the input shaftand the output shaftcoaxially. The serrationof the input shaftand the serrationof the output shaftare formed such that a ratio between the respective numbers of teeth thereof is a decimal, and to specify a relative rotation position of the input shaftand the output shaftrelative to the input mechanismand the output mechanism, a tooth on the serrationof the input shaftand a tooth on the serrationof the output shafthaving a relative position deviation angle about an identical central axis which is equal to or smaller than an allowable value are selected as reference teeth.
