First Practical ORAM for Concealing Access Patterns to Data on the Cloud

Technology Benefits

Solutions to this ORAM problem have existed since 1987, but have not been commercializable due to their enormous internet bandwidth requirements. For example, existing solutions require that the client transfer gigabytes of information to the cloud in order to upload a single megabyte of data. In contrast, the Berkeley approach requires at least 63 times less bandwidth than existing approaches.

Technology Application

This Berkeley ORAM software is compatible with popular cloud storage services (i.e Microsot, Amazon, Google, Dropbox, etc), and accordingly it could be positioned as a security feature to enhance existing cloud storage services. Likewise, this software could also be used to enhance security on private networks.

Title: CONCEALING ACCESS PATTERNS TO ELECTRONIC DATA STORAGE FOR PRIVACY
Usefulness: CONCEALING ACCESS PATTERNS TO ELECTRONIC DATA STORAGE FOR PRIVACY
Summary: Method for concealing access patterns to electronic data storage e.g. RAM such as oblivious RAM (O-RAM) and hard disk drives (HDD), (all claimed) used in military equipment, dynamic RAM memory controller, game console such as Xbox (RTM: Video game brand created by Microsoft) and PlayStation (RTM: Video game console created and developed by Sony Computer Entertainment) and smartcard, etc. Can also be used in solid state disk (SSD), other disk and memory in cloud environment.
Novelty: Method for concealing access patterns to electronic data storage e.g. RAM, involves sorting and shuffling subsets of data blocks repeatedly in each electronic data storage partition during data accesses
