| Research Abstract |
We proposed and implemented a new secure query processing methodology which don't steal sensitive data from the database administrator, in the case the data is stored in the database system on cloud computing environment. Especially, our proposed ShuffledBF, which can hide the schema information of the table, and it preserves the adversaries' inferring from the distribution of each attribute value. In addition, we investigated the following two improvements for speed up the query response time ; (1) the perturbation of bloomfilter index withou shuffling (2) proposing Semi-ShuffledBF which is marged a shuffled bloomfilter and a non-shuffled bloomfilter.
