Disclosed is a method for detecting a data stealthy attack on a networked system with differential privacy protection, which falls within the technical field of information security. The method includes: firstly, modeling a networked system and designing an attack detection scheme based on system noise parameters; then, designing an optimal data stealthy attack scheme for an attacker according to known system information; and then, determining a moment of adding a privacy noise through a privacy noise scheduling scheme while ensuring privacy of sensitive data on the networked system, and achieving an optimal system control performance. Based on the above design, a possible data stealthy attack may be effectively detected on the basis of protecting the system data privacy and ensuring the optimal system performance.
