Abstract:
Privacy Preserving Data Mining (PPDM) aims at performing data mining among multiple parties, and at the meantime, no single party suffers the threat of releasing private data to any others. Nowadays, cloud service becomes more and more popular. However, how to deal with privacy issues of cloud service is still developing. This paper is one of the first researches in cloud server based PPDM. We propose a novel protocol that the cloud server performs data mining in encrypted databases, and our solution can guarantee the privacy of each client. This scheme can protect client from malicious users. With aid of a hardware box, the scheme can also protect clients from untrusted cloud server. Another novel feature of this solution is that it works even when the database from different parties are overlapping.
