Data confidentiality - prevent the cloud from seeing the plaintext data.
Access Privacy - prevent the cloud from inferring information about data from the queries made.
Data confidentiality research:
- The challenge is to allow query processing while keeping the data and query oblivious
- Researchers have mainly taken two approaches
Access Privacy research:
- The challenge is to support minimal leakage of query access pattern while keeping the computational cost to reasonably low so that the approach is practical.
- There are two main paths that researchers have taken to solve this problem:
