Abstract: A busbar unit electrically connected to a motor comprising a stator around which a coil is wound includes: a first terminal including a first body and a first terminal part protruding from an upper portion of the first body and electrically connected to the coil; a first holder configured to support the first terminal such that the first terminal part is exposed to an outside of the busbar unit; and a second holder disposed on an upper portion of the first holder and configured to press the coil against the first terminal part.

Abstract: Provided is a system and method for authentication. The method includes receiving a subscription request from a user terminal, the subscription request executed by an authentication server communicating with the user terminal and including group discrimination data including a group code and information for discriminating a group from another, if it is determined that the group code and the information included in the group discrimination data correspond to each other, performing a group authentication procedure on the user terminal and processing the group authentication procedure as being successful, issuing a member session key to the user terminal, and providing a service requested by the user terminal in response to the service request including the member session key from the user terminal. In one embodiment, it is possible to prevent information on service users from being divulged.
