Main Goal of this Meeting

This is the AIM TF's #24 meeting.

One of our main goals is to have individual member presentations on what problems/challenges they see in AI & Metaverse related to trust.

Starting in the new year (2023), we plan to start drafting white papers or other types of deliverables of the task force.

Guest Speaker: Vivek Nair, Hertz Fellow, UC Berkeley

Anita Rao brief intro.

Vivek Nair develops cutting-edge cryptographic techniques to defend digital infrastructure against sophisticated cyber threats. Nair believes that for every problem that exists in cybersecurity, there is a cryptographic solution waiting to be found. Vivek will present these two recent studies from Berkeley RDI:

Unique Identification of 50,000+ Virtual Reality Users from Head & Hand Motion Data (https://arxiv.org/abs/2302.08927)

Inferring Private Personal Attributes of Virtual Reality Users from Head and Hand Motion Data (https://arxiv.org/abs/2305.1919)

Notes from Vivek's presentation:

  • First study: Historic study of motion based identification in the 70's
  • Basic same idea fast forwarded - distinctions: large number of more diverse Beat Saber game participants 50K+ to make results statistically more significant and representative - game play recordings, and high identification rate 95+%.
  • The motion results are highly effective, comparable to or stronger than Iris, finger prints etc, while facial recognition is more off the chart
  • Context (scene of the play) info is useful but not a major contributor on its own in this study.
  • You can't hide motion data from the Apps - the motion events are important to the game play, so they have to be shared to the apps.
  • Second study: 
  • Take motion data as "language" - as in "body language".
  • Use transformer based learning to answer what additional personal information it can infer with statistically significance, e.g. weight, height, but also income, country, disability... 40+ attributes of personal info.
  • The "privacy layer" of a VR device also typically send all the significant motion data to all devices in the VR because latency requirements demand that rendering happens in the devices locally.
  • It is as if "you walk on a public square and broadcasting all the personal information".
  • We discussed Apple's VisionPro announcement - and its implications to privacy based on the results of these studies. Vivek: We have a very narrow window in devising a solution to this problem before VR devices, as currently designed, become the next iPhone of the world which we can't live without. 
  • THANKS to Vivek Nair for the wonderful presentation - this is hugely important for all of us!
