        • Youakim Badr (PI), School of Graduate Professional Studies
        • Raghu Sangwan, Satish Srinivasan, and Partha Mukherjee, (School of Graduate Professional Studies) (co-PIs)

      • Program: 2020 industryXchange Grant
      • Budget: $48,000, Period: 10/01/2020 – 10/01/2021

Advances in AI combined with sensors, actuators and embedded systems technologies has made it feasible to incorporate intelligence into software intensive-systems with the ability to control and adapt their behavior in real time. Designing AI-centric systems, therefore, has become and will be a norm in the future. These systems are likely to be distributed Managing the complexity that comes with designing such dynamic systems requires risk management to handle uncertainty, safety and dependability that, if not addressed, can make these systems vulnerable to potential threats. However, cybersecurity and vulnerability of AI models to adversarial attacks have raised concerns and lead AI models to misclassify or misbehave. 

This research project has the following objectives:

  • Develop AI Risk Management Framework from holistic and multi-disciplinary perspectives to identify cyber threats and assess cyber-risks and mitigation strategies.
  • Develop fault tolerance mechanisms for AI models to ensure their resilience in production.
  • Extend software testability to AI testability and define new test tactics and patterns.
  • Develop monitoring mechanisms to detect propagation  of threats and vulnerabilities in distributed environments. 

Crowdlearning: Building Trustworthy AI Models from Crowdsourced Data and Edge Computing

      • Team:
        • Youakim Badr (PI), School of Graduate Professional Studies
        • Prasenjit Mitra (co-PI), College of Information Sciences and Technology
      • Program: Center for Security Research and Education – Impact Award
      • Budget: $57,467; Period: 01/11/2021 – 2/01/2022

This project introduces the concept of “crowdlearning” as a participatory method of building AI models, such Deep Neural Networks (DNN), with the help of a large group of contributors. In crowdlearning, contributors, as paid freelancers or volunteers, collaboratively participate to train a global AI model while keeping all their sample data on their devices (personal PC, mobile phones, self-driving cars, etc..). The project aims at developing a secure framework, called crowdlearning platform, with cluster federated learning to enable a collaborative train AI models from local data in trustless environments. The platform includes pruning algorithms to mitigate backdoors, and relies on blockchain-based cybersecurity mechanisms to control access to local data and edge devices and resist DDoS attacks. 

The project tackles the following challenges: 

  • Build a trustworthy federated learning algorithm resistance to adversarial attacks and backdoors.
  • Develop digital identity and authorization protocols without relying on external security authority (i.e., third party identity provider) to empower contributors with full controls on how their local data and computational resources are used. 
  • Develop a fully functional prototype will implement the crowdlearning platform, and demonstrate its feasibility and performance on real-world datasets, including Projected Healthcare Information under HIPAA.

Trusty AI: Trustworthy and reliable Federated Learning with privacy preserving

        • Antoine Boutet (PI), Jan Aalmoes and Thomas Lebrun (co-PIs) – INRIA / INSA de Lyon, France

        • Youakim Badr (co-PI), Robin Qiu, Prasenjit Mitra, Patrick McDenial – Pennsylvania State University

      • Total awarded: $57,467; Period: 01/11/2021 – 2/01/2022

This project aims at developing a secure Federated Machine Learning Framework and tools that preserve the confidentiality of personal data in distributed environments. To this end, we will extend different federated learning approaches and consider their limitations in terms of accuracy, confidentiality, and robustness related to these approaches. In addition, we will enable our Federated Machine Learning Framework with mechanisms to better understand the distributed AI learning process and ensure unbiased fairness that may occur from users data.

This project will also strengthen a partnership between professors from INSA Lyon, School of Graduate Studies, College of Information Science and Technologies, and School of Computer Science and  Engineering at the Pennsylvania State University to not only develop common research topics but also exchange Ph.D. students in Lyon and Penn State research laboratories. 

In addition, the project aims to develop several teaching initiatives to allow students from both institutions to benefit from the Federated Machine Learning Framework as a teaching platform to build federatel learning projects and experiments Cybersecurity attacks on  AI systems. The mutual visits of faculty also aim to promote double degree programs and summer programs.
