| Outline of Final Research Achievements |
In this project, we have conducted a practical research on user location anonymization using dummy locations in location-based service usage. Specifically, we have proposed a dummy generation method based on user preferences on visiting locations, and also proposed a method which requires users to input only a set of visiting locations in advance. These methods are more practical than other existing approaches.
