Core Concepts
Game-theoretic models can effectively defend against online data manipulation attacks through interactive trimming strategies.
Abstract
The exponential growth of data has raised concerns about data integrity, especially in the face of malicious data poisoning attacks. Distance-based defenses like trimming have been proposed but are easily evaded by attackers. Game theory offers a promising approach to address the evasiveness of poisoning attacks. Existing game-theoretical models often overlook the complexities of online data poisoning attacks, where strategies must adapt to dynamic data collection processes. An interactive game-theoretical model is presented in this paper to defend against online data manipulation attacks using the trimming strategy. The model accommodates a complete strategy space and simplifies the derivation of Stackelberg equilibrium. Two strategies, Tit-for-tat and Elastic, are devised from this analytical model and tested on real-world datasets to showcase their effectiveness.
