—Progress in mobile wireless technology has resulted in the increased use of mobile devices to store and manage users’ personal schedules. Users also access popular contextbased services, typically provided by third-party providers, by using these devices for social networking, dating and activitypartner searching applications. Very often, these applications need to determine common availabilities among a set of user schedules. The privacy of the scheduling operation is paramount to the success of such applications, as often users do not want to share their personal schedules with other users or third-parties. Previous research has resulted in solutions that provide privacy guarantees, but they are either too complex or do not fit well in the popular user-provider operational model. In this paper, we propose practical and privacy-preserving solutions to the serverbased scheduling problem. Our novel algorithms take advantage of the homomorphic properties of well-known cryptosystems...
