Mobile terminal apparatus and management apparatus

A user apparatus has a determiner configured to determine whether a relationship degree indicative of a degree of depth of relationship between a first user who manages the user apparatus and a second user who manages an external apparatus that is located within a predetermined range from the user apparatus is at or above a threshold; an acceptor configured to, when a determination result by the determiner is affirmative, accept an input of an instruction that permits lending to the second user a usage authorization to use a service that is available to the first user on the user apparatus; and a lender configured to, when the acceptor accepts the input of the instruction, provide the external apparatus with authorization information to enable the service to be used on the external apparatus.

User apparatus and external apparatus

A security apparatus identifies a first user associated with a first terminal apparatus within an area of a house to which entry is limited by a lock apparatus, and a second user associated with a second terminal apparatus approaching the house. The security apparatus determines a requirement for unlocking for the second user, based on a relationship of the second user with respect to the first user, and then determines whether the requirement for unlocking is satisfied. When the requirement for unlocking is satisfied, the security apparatus controls unlocking of the lock apparatus.
