  Quantum Private Comparison (QPC) allows us to protect private information
during its comparison. In the past various three-party quantum protocols have
been proposed that claim to work well under noisy conditions. Here we tackle
the problem of QPC under noise. We analyze the EPR-based protocol under
depolarizing noise, bit flip and phase flip noise. We show how noise affects
the robustness of the EPR-based protocol. We then present a straightforward
protocol based on CSS codes to perform QPC which is robust against noise and
secure under general attacks.
