Abstract
The paper studies how to release data about a critical infrastructure network (e.g., a power network or
a transportation network) without disclosing sensitive information that can be exploited by malevolent agents, while preserving the realism of the network. It proposes a novel obfuscation mechanism
that combines several privacy-preserving building
blocks with a bi-level optimization model to significantly improve accuracy. The obfuscation is evaluated for both realism and privacy properties on real
energy and transportation networks. Experimental
results show the obfuscation mechanism substantially reduces the potential damage of an attack exploiting the released data to harm the real network
