   A code used to obtain information from several servers privately, i.e., without the servers knowing what information was obtained.
 
   A \(k\)\textit{-server PIR code} is a block code for which one can recover any coordinate of a codeword from \(k\) disjoint sets of coordinates of the codeword \cite{arxiv:1505.06241}.
