A Dynamic Location Privacy Protection Scheme Based on Cloud Storage

摘要


In this paper, we introduce the Cloud serve and build a new location-based service model. By employing the primitive protocols of data encryption and oblivious transfer and following the space anonymous ideas, we further present a dynamic location privacy protection scheme based on Cloud storage. This scheme can ensure both the location privacy of the user and the data privacy of the data service provider in location-based service. Especially, it can greatly reduce the storage, computation and communication costs of the data service provider.
