Is anyone using Acxiom (or a similar service) to perform identity verification and authentication? This could probably be used for self-service password reset as well. Ie. send a one-time link to a person via email and then they have to answer 4 out of 5 questions correct in order to verify who they are to change their password. http://www.acxiom.com/Identity-Solutions/Verification-and-Authentication/ If so, I'd be interested in hearing how it works for you.

For various administrative reasons having nothing to do with security we need to make some big changes to our self-service password reset approach, and I'm trying to capitalize on the opportunity to improve its security at the same time. At the moment, we do what (we think) many other schools do -- provide student id number, netid (username), and date of birth, and you can reset your password. The problem with this is, of course, it was never that hard to come up with that information in the first place, and the combination of students doing more and more stuff online and the growing use of social media makes it just that much easier. So... what other approaches are you taking? There is of course the "pick a few security questions" approach. But it's hard to come up with a set of questions whose answers aren't trivial to guess (either because they have little if any entropy or because the answer is on Facebook). And if you do manage to come up with a set of hard questions, people can't remember what their answers were. Do you use this approach? If so, how have you addressed these problems? We've been tossing around the idea of using something similar to the "email confirmation" links you see many forum-type websites use. In this approach, we would ask the user for some identifying information (netid, student id number, etc.) and then look up the email addresses we have on file. The user could choose any non-university email address in the list, and we would send a randomly-generated URL to that account, which the user could then click on to reset his/her password. Users for whom we have no alternative email on file (or for whom all the ones we have on file are "no good") would have to call the help desk. Does anybody use an approach like this? How well is it working (or not working)? Any other "interesting" approaches out there? Thanks, --Dave -- DAVID A.
