Trusted execution environments (TEEs) canbeused to protect the content of the data during query computation, while supporting differential-private (DP) queries in TEEs provides record privacy when query output isrevealed.

Therefore, if ν() < +, then we can bound(10) with eαν(). To avoid crowded notations, we drop the conditioning onz from Pr[ |ρ = z]. The issue is how to proceed. Let φ be the standard normal density function andΦ be the CDF. The algorithm using SVT suchthat itonly releases the private answerstothe queries if the answer is sufficiently different from the "guess".
