APERIO Systems' Data Forgery Protection (DFP) technology detects and corrects artificial manipulations of industrial process data in real time. It uses advanced proprietary algorithms to identify unique fingerprints in reported signals, validating their integrity and authenticity. The technology alerts operators to forged data and pinpoints the attacked equipment, enabling immediate corrective action without disrupting operations. By combining statistical physics and machine learning, DFP reconstructs the true state of industrial control systems, providing resilience against both internal and external threats. It is a non-intrusive system that minimizes operational risks and maintenance costs, offering low false positive alerts and safeguarding critical infrastructure such as power plants, water systems, and transportation networks.
