Authentication processing system, terminal authentication apparatus, authentication processing method and authentication processing program

An authentication apparatus, comprising:

• an existence confirmation signal receiver which in order to receive an existence confirmation signal outputted from a portable information terminal at a first time interval, is set to a reception mode capable of receiving said existence confirmation signal at a second time interval, only during a third time interval equal to or longer than said first time interval;
• an existence notice signal transmitter which transmits said existence notice signal serving as response of said existence confirmation signal to said portable information terminal when said existence notice signal is received;
• a link connection unit configured to establish a wireless link with said portable information terminal after said existence notice signal has been received by said portable information terminal;
• an authentication unit configured to conduct authentication with said portable information terminal through said wireless link;
• and
• a control command transmitter which transmits a control command when said authentication has been succeeded.

An authentication processing method of an authentication processing system comprising a portable information terminal;

• a terminal authentication apparatus which conducts authentication processing by air;
• and an operation apparatus which conducts a prescribed operation when said terminal authentication apparatus has succeeded in authentication with said portable information terminal,
• wherein said portable information terminal includes:
• transmitting an existence confirmation signal to confirm whether or not said terminal authentication apparatus exists, at a first time interval;
• receiving an existence notice signal transmitted from said terminal authentication apparatus in response to said existence confirmation signal;
• establishing a wireless link with said terminal authentication apparatus which has transmitted said existence notice signal when said existence notice signal is received;
• and
• conducting a first authentication with said terminal authentication apparatus through said wireless link,
• wherein said terminal authentication apparatus includes:
• setting to a reception mode capable of receiving said existence confirmation signal at a second time interval only during a third time interval equal to or longer than said first time interval;
• transmitting said existence notice signal serving as response of said existence confirmation signal to said portable information terminal when said existence confirmation signal is received;
• establishing a wireless link with said portable information terminal after said portable information terminal receives said existence notice signal;
• conducting the authentication with said portable information terminal through said wireless link;
• and
• transmitting a control command for said operation apparatus when the authentication is succeeded,
• wherein said operation apparatus includes:
• receiving said control command;
• and
• conducting said prescribed operation based on said control command.

An authentication processing program, allows a computer to execute the steps of:

• in order to an existence confirmation signal outputted from a portable information terminal at first time interval, setting to a reception mode capable of receiving said existence confirmation signal at a second time interval only during a third time interval equal to or longer than said first time interval;
• transmitting said existence notice signal serving as response of said existence confirmation signal to said portable information terminal when said existence confirmation signal is received;
• establishing a wireless link with said portable information terminal after said portable information terminal receives said existence notice signal;
• conducting the authentication with said portable information terminal through said wireless link;
• and
• transmitting a control command for said operation apparatus when the authentication is succeeded, in order to allow said operation apparatus to conduct a prescribed operation.
