When signing up for new accounts, web apps often ask for the answer to a 'security question', i.e. Dog's name, etc.
I'd like to go through our database and look for instances where users just mashed the keyboard instead of providing a legitimate answer - this is a high indicator of an abusive/fraudulent account.
"Mother's maiden name?" lakdsjflkaj
Any suggestions as to how I should go about doing this?
Note: I'm not ONLY using regular expressions on these 'security question answers'
The 'answers' can be:
Selected from a db using a few basic sql regexes
Analyzed as many times as necessary using python regexes
Compared/pruned/scored as needed
This is a technical question, not a philosophical one ;-)
Thanks!
