METHOD AND SYSTEM FOR STORING AND RETRIEVING DATA USING HASH-ACCESSED MULTIPLE DATA STORES

摘要

A method and system for storing and retrieving data using hash-accessed multiple data stores (Fig. 2), provides data protection while requiring low computational overhead and further provides storage and retrieval access based on only a single piece of access information, which is generally public. The algorithms provide high security against data-mining and other examination of the data stores. The access information is hashed and is split into offset fields used as indices into a plurality of data stores, generating a quasi-random relationship between the access information and the location of portions of a stored data element. Further protection may be provided by striping the data across the data stores in conformity with a striping order selected by a field of the hashed access information.
