Abstract EN
In the interest of privacy concerns, cloud service users choose to encrypt their personal data before outsourcing them to cloud.
However, it is difficult to achieve efficient search over encrypted cloud data.
Therefore, how to design an efficient and accurate search scheme over large-scale encrypted cloud data is a challenge.
In this paper, we integrate bisecting k-means algorithm and multibranch tree structure and propose the α-filtering tree search scheme based on bisecting k-means clusters.
The novel index tree is built from bottom-up, and a greedy depth first algorithm is used for filtering the nonrelevant document cluster by calculating the relevance score between the filtering vector and the query vector.
The α-filtering tree can improve the efficiency without the loss of search accuracy.
The experiment on a real-world dataset demonstrates the effectiveness of our scheme.
