Is there a defined method to choose value of $t$ when using fuzzy extractor to reconcile two close secrets?

I did try with multiple values ranging from 5 to close to half of the sequence. I understand it statistically depends on chance of error, difference between close sets.

    $\begingroup$ Could you add some more background about what particular extractor you're using, please? I have no clue what $t$ is. :) $\endgroup$ – Elias Jun 24 '17 at 7:35

  • $\begingroup$ I'm not an academic, so their paper is difficult to understand. I am a pragmatist however. I don't see any testing. I expected to see something like Lena with and without her hat outputting the same value, or at least a match %age Does their theory actually work? $\endgroup$ – Paul Uszak Jun 24 '17 at 12:37
  • $\begingroup$ Yes this works where I use $t$ empirically. Do you know any other fuzzy extractor which works well to extract common secret from two close inputs? $\endgroup$ – Jay Jun 24 '17 at 14:19

I did find that it depends on maximum number of mismatch between sets.
