The following link is to a white paper on the material discussed:

Following the presentation some question were addressed:

1. Q: Can the process be used across multiple platforms? A: This is an area under development. As along as a uniform salt is used in the hashing process of the user traits across multiple platforms, such as for a phone or tablet, the traits can be compared across platforms.

2. Are traits independent enough that probabilities computed for traits belonging to the same individual can be combined to get an overall higher identification probability? This needs further investigation but the difference seen in individual traits shows the traits are relatively independent. For example it is unlikely that a song list and contact list will be of the same length.

There were then some discussions of the app based on using traits.
