CA 2503083
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 the 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 proximity but also multi-dimensional data such as preference profiles and vectors (e.g., an affinity for baseball, apple pie, and ballroom dancing.).
L'invention concerne un moyen permettant de calculer la proximité (proximité basée sur l'emplacement ou sur les préférences) entre des abonnés sans fil mobiles (qui utilisent des services différents) sans que l'emplacement/les préférences de l'un ne soient divulgués à l'autre (conservation de l'anonymat). L'anonymat est conservé par apport d'informations d'emplacement/de préférences par étapes, avec une fonction d'évaluation. Les services reçoivent des résultats partiels puis calculent localement le résultat final, ou la proximité. Le terme proximité n'inclut pas seulement la proximité physique, mais également des données multi-dimensionnelles de type profils et vecteurs de préférences (par exemple, une affinité pour le base-ball, la tarte aux pommes, et la danse de salon).
