How to protect your digital footprint

(InvestigateTV) — According to Pew Research, 72% of Americans believe there should be more regulations around how companies handle their personal data, often referred to as a digital footprint.

A digital footprint is the trail of data you leave behind whenever you visit websites, send emails, download apps, or create online and social media accounts.

A separate Pew study from late 2024 found that 96% of Americans use the internet, meaning most of us have a pretty extensive digital footprint.

Social media expert Marcy Thornhill points out that credit card numbers are often linked to these digital footprints, making them especially vulnerable.

“You’re leaving a footprint every time you use your credit card; every time you log into an app to make a purchase or even browse,” Thornhill explained. “You’ll notice sometimes that if you’re saying something about Nike or a company, you may see a pop up on Facebook. That’s part of the digital recognition that it knows in advance what you’re looking for.”

Thornhill said Google users can see all the credit cards that have ever been used on the platform. By accessing Google account settings and clicking on “Payments,” users will find a list of every credit card ever used to make a purchase.

“So, if someone hacked your Google account, guess what? Now they have access to all those credit cards,” she cautioned. “Same thing with your Amazon purchases subscriptions. Oftentimes subscriptions go through Amazon, but you’ll see all those apps out there that you probably subscribed to years ago. You’re no longer using, but they’re wide open for hackers.”

Thornhill recommended regularly reviewing your accounts and apps to remove outdated credit card information whenever possible.

She also encouraged people to see if their financial institution offers the option of using a virtual credit or debit card.

A virtual card puts a buffer between users and potential hackers. It exists solely in digital form, allowing for secure online and in-store purchases without exposing your physical card.
