Abstract: Described is a way for computing proximity (location-based proximity or preference-based proximity) between mobile wireless subscribers (who use different services) without either divulging their location/preference to th e other (preservation of privacy). Privacy is kept by providing location/preference information in steps, along with an evaluation function. The services receive partial results and then locally compute the final result, or proximity. The term proximity includes not just physical proximit y but also multi-dimensional data such as preference profiles and vectors (e.g ., an affinity for baseball, apple pie, and ballroom dancing.).
