Data Privacy and LPR—How to Ensure Your Data is Secure

Have you ever felt your stomach drop a little after realizing you clicked “accept” on something without reading it? If it was an app update or one of those website cookie banners, it probably wasn’t a big deal. But when there’s sensitive data involved, skipping the fine print and blindly accepting is never a good idea.

License plate recognition (LPR) helps teams identify vehicles of interest, investigate incidents faster, and understand vehicle activity across one or multiple properties. But it also creates data that needs to be protected, governed, and controlled carefully. You don’t want to blindly accept the fine print where license plate data is involved. 

People Want Safer Parking Lots 

One thing we can all agree on is that creating safer parking lots is a good thing. LPR software can help us move toward that outcome. In a recent survey, 78% of U.S. adults said they feel safer parking in a retail or public parking lot that uses automated license plate readers over one that does not. 

But the same survey also shows that people do not want open-ended data collection. Sixty-seven percent said non-suspicious license plate data should be securely deleted within 30 days, while 22% said it should be deleted immediately. Another 87% said signs should be visible notifying people that ALPRs are in use.

People want the safety benefits of license plate recognition, but they also expect transparency, limits, and clear rules for how the data is handled.

If License Plates Are Public, Why Is License Plate Recognition Data Sensitive?

A license plate is legally required to be publicly visible. On its own, a license plate number is not personally identifiable information. The general public can’t freely reverse a plate number into a home address or identity without access to restricted government databases. 

But an LPR system does more than capture a plate number. It captures a license plate image, timestamps the image, logs a geolocation, and records basic vehicle characteristics like make and color. What makes LPR data sensitive is the patterns that emerge when that data is aggregated over time and across multiple locations. A person's movements, routines, and associations can be reconstructed from enough scan records. 

That can be extremely helpful for security teams. If the same vehicle appears before multiple thefts or a known vehicle enters a restricted area, LPR software helps them connect the dots faster than manual video review can. But in the wrong hands or without clear governance, that data can be misused.

Questions to Ask LPR Providers

Who Will Have Access to LPR Data?

A responsible LPR software provider should treat customer data like customer property, not shared network inventory. If a vendor can’t clearly explain (and contractually guarantee) who can access your data and under what conditions, proceed with caution. 

Where Does Data Live?

LPR data stored in a public cloud environment is categorically different from data stored in a private, customer-controlled environment. Public cloud means your data exists on shared infrastructure, subject to that infrastructure's security practices and, depending on the vendor's agreements, potentially accessible to third parties. AI security camera software that keeps data off public networks helps limit exposure.

What Does the Audit Trail Look Like?

If someone queries your LPR database, that action should be logged with a timestamp, a user ID, and a stated reason. An audit trail is what allows you to detect misuse and demonstrate responsible data security practices if your handling is ever challenged.

Implement Your Own LPR Governance Rules

Even with the right provider, organizations should still implement internal rules for how license plate recognition data is used. A vendor can provide secure technology, but it's on your internal team to decide who gets access, what counts as a legitimate search, how long data should be kept, and how requests for information are handled. 

Start by defining rules around access. Only let people who need LPR data to do their jobs search it, export it, or share it. Then define acceptable use clearly so employees know the difference between a legitimate security purpose and curiosity-driven searches (which shouldn’t be allowed).

Finally, think about retention. Often, the older the data, the less useful it becomes. Deleting old LPR records reduces the amount of data that could be misused, over-searched, or wrongly shared—without weakening your ability to investigate recent incidents. Decide how long LPR data should be kept and enforce that timeline. 

LVT’s Approach to LPR Data Privacy

Our approach to LPR starts with customer control. LPR data is securely confined to an individual customer’s environment, and customers retain full control of that data, including the option to authorize sharing with third parties. 

We never sell customer data. LPR data should support security operations, investigations, and site awareness. It should not become a product sold outside the customer relationship. We also have a clear standard for law enforcement access. Customers can choose to share footage with law enforcement, but we don’t provide footage or customer data unless required by law with a subpoena. 

Finally, we secure all data captured by LVT® Units on private networks rather than public ones. In fact, LVT is the only cellular-based solution with its own cellular network. That helps keep sensitive plate data in the customer’s controlled environment and limits unnecessary exposure.

Secure LPR Data Starts With Reading the Fine Print

License plate recognition can help security teams spot vehicles of interest, investigate incidents faster, and make parking lots safer. But the privacy side of LPR can’t be an afterthought. It’s important to know who controls the data, where it is stored, how long it is kept, and when it can be shared. Asking the right questions and reading the fine print can be the difference between using LPR as a responsible security tool and blindly accepting terms that create avoidable risk.
