Analysis and Mitigations of Reverse Engineering Attacks on Local Feature Descriptors

Understand

As autonomous driving and augmented reality evolve, a practical concern is data privacy.

• In particular, these applications rely on localization based on user images.
• The widely adopted technology uses local feature descriptors, which are derived from the images and it was long thought that they could not be reverted back.
• However, recent work has demonstrated that under certain conditions reverse engineering attacks are possible and allow an adversary to reconstruct RGB images.
