You wrote to my question about anonymous questionnarires:
Correlation is easy; assign people consecutive numbers or somesuch. If both participants are anonymous, no problem. Could you bring by the questionnaire by hand, in exchange for cash?
No, they are too far away.
If not, how about a money order and a PO box?
They would still need my name.
The audit part of this is the tough part. Would the HHS care to agree to a broadcast means of verification? Would participants 44, 71 and 94 please come into the re-testing center to verify their participation? There could be a zero knowledge proof of some type to demonstrate that you are really patient 94.
Can someone suggest a way to accomplish all this? TIA, -- Lucky Green <shamrock@netcom.com> PGP public key by finger
