Distributed Anonymization for Multiple Data Providers in a Cloud System

摘要: With the proliferation of cloud computing, there is an increasing need for sharing data repositories containing personal information across multiple distributed databases, and such subject to different privacy constraints individuals. Most existing methods focus on single database anonymization, although concept anonymization was discussed in some literatures, it only provides uniform approach that exerts same amount preservation all providers, without catering user’s specific requirements. The consequence we may offer insufficient protection a subset people, while applying excessive budget others. Motivated by this, present new protocol based personalized preservation. Our technique performs satisfy provider’s requirements, then publish their global view any breaches. Extensive experiments have been conducted verify our proposed method are efficient effective.
