In the past Block, I think I have seen a presentation about a biometric wallet using fuzzy extractor or something with helper data to generate a deterministic key pair with sufficient entropy. However, I was not able to locate it. Could someone point me to the right file? Perhaps @saki-otsuki ?
this one?
I think she provided a more detailled presentation some time ago… but not sure when.
In any case, @nat if you are interested by the topic of key extraction from biometrics, I am happy to discuss it as well.
As far as I remember, I presented in Block 10 and Block 11 (Mitchell’s post). Please find the material from Block 10 here.
Thanks, @saki-otsuki. I thought there was a little more detailed one, but I may be hallucinating 
@JBringer Yes, I am interested in the topic. I started to reviewing it in the context of the Block 14 where biometric identification would be discussed, but I recon that it would be useful in many other usecases than blockchain wallets. Are you going to be at Block 14 or SC27/WGs meeting in Nürnberg?
both Talk to you very soon
