SHIELD: Thwarting Code Authorship Attribution. (arXiv:2304.13255v1 [cs.CR])

Authorship attribution has become increasingly accurate, posing a serious
privacy risk for programmers who wish to remain anonymous. In this paper, we
introduce SHIELD to examine the robustness of different code authorship
attribution approaches against adversarial code examples. We define four
attacks on attribution techniques, which include targeted and non-targeted
attacks, and realize them using adversarial code perturbation. We experiment
with a dataset of 200 programmers from the Google Code Jam competition to
validate our methods targeting six state-of-the-art authorship …
