Have you used insurance price comparison sites comparethemarket.com (you know...with the meerkat) and confused.com? If so, you'd better check out the recent investigation conducted by PC Pro.
According to their research, you can access the full quote history of an account holder armed only with their name, date of birth and email address - information that can usually be gleaned from social networking sites (or obtained in casual conversation).
Confused.com seemed to be only a little better - you need to also have the postcode to reset a password there! Oh, and no email is sent to the account holder confirming the password change.
Clearly, given the nature of their business, both of these sites have published privacy and security statements. Just goes to show that you can't rely on fine words when it comes to your digital privacy.
Just for the record, I never supply my actual date of birth, postcode, etcetera unless it is legally required (e.g. in applying for car insurance...unfortunately). I've seen date of birth used as a security question in all sorts of inappropriate places. Where possible, treat it like a password - i.e. make one up.
