Provable Data Recoverability and Hide-Able Access Pattern Based ORAM
With the development and application of cloud computing
more and more customers choose cloud storage as the storage medium
therefore
data integrity and privacy become a major problem that the customers concern. A new structure based on oblivious RAM model was proposed. The customer file was composed by data blocks of equal-sized
and each data block had two backups in the cloud storage
and they were randomly stored in different cloud files in order to ensure data integrity. Oblivious RAM allowed a client to hide its data access patterns from an untrusted server. The data possession was verified to utilize homomorphic hash algorithm. The adversary can not obtain useful information from the client access data pattern
and the data privacy is guaranteed.
