Query: Private Information Retrieval in Distributed Storage Systems Using an
  Arbitrary Linear Code   We propose an information-theoretic private information retrieval (PIR)
scheme for distributed storage systems where data is stored using a linear
systematic code of rate $R > 1/2$. The proposed scheme generalizes the PIR
scheme for data stored using maximum distance separable codes recently proposed
by Tajeddine and El Rouayheb for the scenario of a single spy node. We further
propose an algorithm to optimize the communication price of privacy (cPoP)
using the structure of the underlying linear code. As an example, we apply the
proposed algorithm to several distributed storage codes, showing that the cPoP
can be significantly reduced by exploiting the structure of the distributed
storage code.
