Using Honeypots in a Decentralized Framework to Defend Against Adversarial Machine Learning Attacks
The market demand for online machine learning services is increasing, and so have the threats against them. Adversarial inputs represent a new threat to Machine Learning as a Services (MLaaSs) Meticulously crafted malicious inputs can be used to mislead and confuse the learning model, even in cases where the adversary only has limited access to input and output labels. As a result, there has been an increased interest in defence techniques to combat these types of attacks. In this paper, we propose a network of High Interaction Honeypots (HIHP) as a decentralized defence framework that prevents an adversary from corrupting the learning model. We accomplish our aim by (1) preventing the attacker from correctly learning the labels and approximating the architecture of the black box system; (2) luring the attacker away, towards a decoy model, using Adversarial HoneyTokens; and finally (3) creating infeasible computational work for the adversary.
