[Air-l] secure servers and/or encryption for surveys?

[Sandra Braman]

I was struck by a recent message to the list asking for volunteers for a 
web-based survey in which seemingly half the message consisted of warnings 
about the insecurity of web-based survey responses.  Does anyone have 
experience with using the security techniques so familiar from e-commerce 
to ensure those participating in web-based research of 
confidentiality?  Anyone know how widespread this practice is?

Thanks --
