A framework for the extraction of Deep Neural Networks by leveraging public data

Pal, Soham, Gupta, Yash, Shukla, Aditya et al.

Understand

Machine learning models trained on confidential datasets are increasingly being deployed for profit.

  • Machine Learning as a Service (MLaaS) has made such models easily accessible to end-users.
  • Prior work has developed model extraction attacks, in which an adversary extracts an approximation of MLaaS models by making black-box queries to it.
  • However, none of these works is able to satisfy all the three essential criteria for practical model extraction: (1) the ability to work on deep learning models, (2) the non-requirement of domain knowledge and (3) the ability to work with a limited query budget.
