Systematically Assessing the Security Risks of AI/ML-enabled Connected Healthcare Systems

no code implementations30 Jan 2024 Mohammed Elnawawy, Mohammadreza Hallajiyan, Gargi Mitra, Shahrear Iqbal, Karthik Pattabiraman

We show that the use of ML in medical systems, particularly connected systems that involve interfacing the ML engine with multiple peripheral devices, has security risks that might cause life-threatening damage to a patient's health in case of adversarial interventions.

A Low-cost Strategic Monitoring Approach for Scalable and Interpretable Error Detection in Deep Neural Networks

no code implementations31 Oct 2023 Florian Geissler, Syed Qutub, Michael Paulitsch, Karthik Pattabiraman

We present a highly compact run-time monitoring approach for deep computer vision networks that extracts selected knowledge from only a few (down to merely two) hidden layers, yet can efficiently detect silent data corruption originating from both hardware memory and input faults.

Overconfidence is a Dangerous Thing: Mitigating Membership Inference Attacks by Enforcing Less Confident Prediction

1 code implementation4 Jul 2023 Zitao Chen, Karthik Pattabiraman

Machine learning (ML) models are vulnerable to membership inference attacks (MIAs), which determine whether a given input is used for training the target model.

Towards a Safety Case for Hardware Fault Tolerance in Convolutional Neural Networks Using Activation Range Supervision

no code implementations16 Aug 2021 Florian Geissler, Syed Qutub, Sayanta Roychowdhury, Ali Asgari, Yang Peng, Akash Dhamasia, Ralf Graefe, Karthik Pattabiraman, Michael Paulitsch

Convolutional neural networks (CNNs) have become an established part of numerous safety-critical computer vision applications, including human robot interactions and automated driving.

Jujutsu: A Two-stage Defense against Adversarial Patch Attacks on Deep Neural Networks

1 code implementation11 Aug 2021 Zitao Chen, Pritam Dash, Karthik Pattabiraman

Therefore, Jujutsu leverages generative adversarial networks (GAN) to perform localized attack recovery by synthesizing the semantic contents of the input that are corrupted by the attacks, and reconstructs a ``clean'' input for correct prediction.

ReLUSyn: Synthesizing Stealthy Attacks for Deep Neural Network Based Cyber-Physical Systems

no code implementations21 May 2021 Aarti Kashyap, Syed Mubashir Iqbal, Karthik Pattabiraman, Margo Seltzer

These attacks, which we call Ripple False Data Injection Attacks (rfdia), use minimal input perturbations to stealthily change the dnn output.

Collision Avoidance Management

A Low-cost Fault Corrector for Deep Neural Networks through Range Restriction

no code implementations30 Mar 2020 Zitao Chen, Guanpeng Li, Karthik Pattabiraman

The adoption of deep neural networks (DNNs) in safety-critical domains has engendered serious reliability concerns.
