Certified Robustness to Adversarial Examples with Differential Privacy
TL;DR: PixelDP as discussed by the authors is based on a connection between robustness against adversarial examples and differential privacy, a cryptographically-inspired privacy formalism, that provides a rigorous, generic, and flexible foundation for defense.

Certified Robustness to Adversarial Examples with Differential Privacy
TL;DR: This paper presents the first certified defense that both scales to large networks and datasets and applies broadly to arbitrary model types, based on a novel connection between robustness against adversarial examples and differential privacy, a cryptographically-inspired privacy formalism.

Vanish: increasing data privacy with self-destructing data
TL;DR: Vanish is presented, a system that meets this challenge through a novel integration of cryptographic techniques with global-scale, P2P, distributed hash tables (DHTs) and meets the privacy-preserving goals described above.

CleanOS: limiting mobile data exposure with idle eviction
TL;DR: This paper presents CleanOS, a new Android-based operating system that manages sensitive data rigorously and maintains a clean environment at all times and instrumented Android's Dalvik interpreter to securely evict that data after a specified period of non-use.
