Management and Search of Private Data on Storage Clouds

The article presents a solution for storage and management of private data kept in Internet Storage Clouds. The solution supports operations over the data kept ciphered, including reads, writes and searches based on multiple keywords and relevance classification. The approach is based on a middleware architecture supported by homomorphic encryption techniques combined with dynamic indexing mechanisms. The solution preserves conditions of privacy without need to either decipher data during operations in the cloud or transfer the data during searches. The article further describes an implementation prototype of the solution and its evaluation. The performance obtained in different implementation scenarios is analyzed and compared to a solution promoted by AMAZON S3. The evaluation shows that the solution is viable, offers more security and control for the user and does not aggravate conditions of latency and data availability.
