I read the article yesterday where McLean’s acquired the phone records of the Canadian Privacy Commissioner. This will get interesting over the next while as the Privacy Commissioner’s investigation unfolds.
It is unclear from the article exactly how the records were obtained. There are several theories, but there is not much point speculating on that until we know for sure.
The article states that: The most likely explanation is that they simply call up and ask for it. Phone companies, it seems, are rather easily duped. If a caller posing as a customer furnishes them with the right name, number and address — sometimes they will also ask for a postal code or date of birth — they will take that person at their word.
While we do not know whether that is the case or not, it does illustrate a practical difficulty that many have struggled with.
On the one hand, it is important that businesses only discuss an individual’s account with that individual. So businesses often ask for a significant amount of information when one calls in an attempt to ensure it is indeed the person. But that can only be taken so far – or it becomes impractical, and upsets legitimate customers.
And if they get into verification information that is not necessary to know to provide the service it becomes dangerous. That violates the privacy principle that a business should not collect info unnecessary to provide the service. It also increases the risk of harm if that information should be compromised.
If someone that has stolen the individual’s identity or has improperly obtained significant amounts of personal information calls a business, how can a business avoid being duped?
I don’t know what the answer is to this conundrum – short of some technological method of identification/verification that works both over the Net and on the phone.
Nothing may be foolproof, but at least it might raise the bar for the amount of sophistication, time, and expense needed to pull off the impersonation.
