Characterizing Server Compromise: Resilience Models, Instantiations, and Impossibilities

Creator:

McQuoid, Ian M.

Abstract:

One of the pervasive problems arising in our modern, digital world surrounds data breaches where an adversary, through zero-day exploitations, phishing, or old-fashioned social engineering attacks, gains access to a service’s data stores. Our society increasingly relies on these cloud-based services for everything from our taxes to personal communication. As...

Two Sides of a Coin: Adversarial-Based Image Privacy and Defending Against Adversarial Perturbations for Robust CNNs

Creator:

Rajabi, Arezoo

Abstract:

Emergence of highly accurate Convolutional Neural Networks (CNNs) with the capability to process large datasets, has led to their popularity in many applications, including safety/security-sensitive (e.g. disease recognition, self-driving cars). Despite the high accuracy of convolutional neural networks, they have been found to be susceptible to adversarial noise added to...

Computing the Fréchet Distance Between Surfaces

Creator:

Xu, Hanzhong

Abstract:

The Fréchet distance is a measure of similarity between curves or surfaces. The Fréchet distance between two polygons can be computed in polynomial time, but it is much harder to compute the Fréchet distance between surfaces. We present the ﬁrst (1+ε)-approximation algorithm and the ﬁrst exact algorithm for computing the...
