# Value of $t$ in Fuzzy Exractor

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.

• Could you add some more background about what particular extractor you're using, please? I have no clue what $t$ is. :) – Elias Jun 24 '17 at 7:35
• I am using cs.bu.edu/~reyzin/fuzzy.html – Jay Jun 24 '17 at 10:06
• 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? – Paul Uszak Jun 24 '17 at 12:37
• 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? – Jay Jun 24 '17 at 14:19
