Private Fraud Prevention

Hi everyone,

We just posted a public repo<https://github.com/siyengar/private-fraud-prevention> that demonstrates a technique for fighting fraud in anonymous reporting by using blind cryptographic signatures. Mitigating fraud is something we are passionate about at Facebook, which should come as no surprise considering how often Ben addresses it in this forum.

We would really appreciate it if some of the other people on this call read through the ideas and process flow (and feel free to try out the demo if you have time!). I would be very happy to talk about any of the ideas or answer questions on this week's call.

Cheers,
Andrew
