Abstract
A system for privacy protection includes a processor and a terminal including a location detection device. The processor performs: identifying a presence possible ranges of the terminal at a first time and at a second time earlier than the first time from a combination of information on a first region including the location at the first time, and information on a second region including the location at the second time and having been already transmitted to an external apparatus; determining whether each of the identified presence possible ranges satisfies a preset condition for a presence possible range that may be known by a third party; when the condition is not satisfied, transmitting the information on a third region including the first region and a region other than the first region, as information on a region where the terminal is present at the first time, to the external apparatus.
