What is… critical personal data?
We consider these to be amongst your personal critical data:
- National Insurance number
- Credit card number(s)
- Phone number
- Passport number
Here’s how to protect them in a breach:
NI: This is the most dangerous form of data theft. Identity theft is most commonly based upon stolen national insurance details. Your national insurance number can be used criminally for everything from obtaining credit or goods in your name to impersonating you to get medical services, government benefits, employment – even using your identity in legal matters. Contact the National Insurance numbers helpline and answer some questions (you’ll need to fill in form a form they issue called CA5403 if you cannot answer the questions)
Credit card: Monitor your credit card often and immediately report potentially fraudulent purchases to your credit card company, regardless of the amount. Small amounts to obscure organisations are often the trail to larger credit card fraud. It’s not enough to read through your transactions once a month when your credit card statement comes. In fact, some credit cards can send real-time transaction notifications to your smartphone to help you monitor payments. That amounts to a few minutes a day for most people.
Phone number: Most people are highly unlikely to want to change their phone number (or their personal email address). However, phone calls can be spoofed to make it look like they come from you and you should contact your phone service provider if you think that is happening to anyone on your contacts list.
Passport: You should immediately contact the agency that issued your passport.
