The indexing technique in distributed object storage system is the crucial part of a large scale application, where the index data structure may be published in many nodes. Here arises a problem on preserving the privacy of the ownership information while supporting queries on item locations with limited index space. Probabilistic data structure, such as the bloom filter which records the location of each item in distributed nodes, is one of the promising solutions. The data structure uses a hashed vector to index items on the nodes.
