PROBLEM TO BE SOLVED: To automatically discriminate whether a specific portable terminal is present within a prescribed range.;SOLUTION: This terminal presence/absence discrimination device 310, for discriminating whether the specific portable terminal X1 is present within the prescribed range, includes a connection information acquiring part 311 for acquiring connection information of the portable terminal X1 specified by request information in accordance with the reception of the request information requesting discrimination, and a discriminating part 312 for collating a part of the acquired connection information with information based on a part of the request information to discriminate that the specified portable terminal X1 is present within the prescribed range when position information showing a position on a network coincides. Thereby, if the connection of the portable terminal X1 is changed, a discrimination result as to whether the portable terminal X1 is present within the prescribed range changes. Consequently, for example, such a mechanism can be used to automatically perform viewing limitation.;COPYRIGHT: (C)2010,JPO&INPIT
