Adore: Differentially Oblivious Relational Database Operators. (arXiv:2212.05176v1 [cs.DB])

There has been a recent effort in applying differential privacy on memory
access patterns to enhance data privacy. This is called differential
obliviousness. Differential obliviousness is a promising direction because it
provides a principled trade-off between performance and desired level of
privacy. To date, it is still an open question whether differential
obliviousness can speed up database processing with respect to full
obliviousness. In this paper, we present the design and implementation of three
new major database operators: selection with …
