Fingerprint Privacy Lawyer

A fingerprint can be used to unlock a phone, enter a secured building, clock in for work, verify an identity, or gain access to an account. Unlike a password or identification number, however, a fingerprint is tied to a person’s physical characteristics and cannot simply be replaced if the underlying biometric information is compromised.

That difference has made fingerprint privacy an increasingly important part of biometric law.

Businesses and technology providers may use fingerprint-based systems for legitimate purposes. The legal issues often involve what happened before and after the scan: whether appropriate notice was provided, whether consent was required, how fingerprint data was stored, how long it was retained, whether it was disclosed to another company, and whether applicable biometric privacy laws were followed.

Net Law Advocates represents individuals nationwide in matters involving fingerprints and other forms of biometric privacy.

Why Are Fingerprints Considered Biometric Data?

Biometric technologies use measurable physical or behavioral characteristics to recognize or identify individuals.

Fingerprints are one of the most established examples.

The ridges and patterns on a person’s fingers contain distinctive characteristics that can be analyzed by biometric systems. Instead of relying on something a person knows, such as a password, the system uses something physically associated with that individual.

A fingerprint system does not necessarily store an ordinary photograph of the finger.

Depending on the technology, a scanner may analyze characteristics of the fingerprint and create a digital representation or template that can later be compared with another scan.

The distinction between a fingerprint image and information derived from that image can become legally important because biometric statutes define protected information differently.

Illinois’ Biometric Information Privacy Act, commonly known as BIPA, expressly identifies a fingerprint as a biometric identifier. Other states use their own definitions and requirements.

Where Are Fingerprint Systems Used?

Fingerprint technology has moved far beyond law enforcement.

Businesses and organizations can use fingerprint systems for authentication, security, identification, and workforce management.

Common uses include:

• Employee timekeeping
• Building and restricted-area access
• Computer or device authentication
• Account verification
• Customer identification
• Membership systems
• Financial services
• Healthcare environments
• Schools and educational facilities
• Security systems

The privacy implications depend heavily on the context.

Using a fingerprint to unlock a personal smartphone can involve a very different data relationship from an employer requiring hundreds of employees to scan their fingers into a timekeeping system operated by an outside vendor.

The important questions include who receives the biometric information, where it is stored, what it is used for, and what happens to it afterward.

A Fingerprint Scan Can Create a Biometric Template

Many biometric systems do not need to retain a traditional image of someone’s fingerprint to recognize that person later.

Instead, the technology may extract distinctive characteristics and convert them into a mathematical or digital representation often described as a biometric template.

When the person returns, a new scan can be compared against the stored template to determine whether there is a match.

That technical process can matter legally.

Biometric privacy laws do not all use identical definitions, and whether a particular template or derived data qualifies as protected biometric information can depend on the statute and how the technology functions.

For someone concerned about fingerprint collection, the relevant question is therefore not always simply, “Did the company save a picture of my fingerprint?”

It may also be necessary to determine what information the scanner generated and what happened to that information after the scan.

Consent Can Be Central to Fingerprint Privacy

Some biometric privacy laws impose requirements before a business collects covered fingerprint information.

Illinois provides one of the country’s most significant examples.

Under BIPA, a private entity generally may not collect, capture, purchase, receive through trade, or otherwise obtain a person’s biometric identifier or biometric information unless it first informs the individual in writing that the information is being collected or stored, informs the person in writing of the specific purpose and length of time for which it is being collected, stored, and used, and receives a written release.

Whether those requirements apply to a particular fingerprint system depends on the circumstances and statutory definitions.

Other states use different approaches.

Texas law, for example, includes fingerprints within its definition of biometric identifiers and restricts capture of biometric identifiers for a commercial purpose unless the individual is informed beforehand and provides consent.

Washington regulates the enrollment of biometric identifiers in databases for commercial purposes through its own notice-and-consent framework.

The existence of biometric protections in several states does not mean the rights or remedies are identical nationwide.

Fingerprints Used at Work Can Raise Particular Privacy Issues

One of the most common commercial uses of fingerprint technology is employee identification.

Employers may use fingerprints to clock workers in and out, control access to secure areas, authenticate employees on computer systems, or replace identification cards and PIN numbers.

These systems can be convenient because employees do not need to remember passwords or carry physical credentials.

They also create privacy questions because workers may have little practical choice about using technology required for their jobs.

For example, an employee may be instructed to begin using a fingerprint scanner without knowing:

• What biometric information the system creates
• Whether the employer or a vendor stores it
• How long it will be retained
• Whether another company receives it
• What happens to it after employment ends

Workplace fingerprint systems have played a significant role in biometric privacy litigation, particularly under Illinois BIPA.

Because employee biometrics extend beyond fingerprints alone, broader workplace issues are addressed separately through Net Law Advocates’ workplace biometric privacy content.

Fingerprint Time Clocks Present Their Own Privacy Questions

Fingerprint time clocks are a particularly common form of workplace biometric technology.

Instead of entering an employee number or swiping a card, a worker places a finger on a scanner when beginning or ending a shift. The system compares the scan with biometric information associated with that employee.

This can help employers prevent practices such as one worker clocking in for another.

But the convenience of biometric timekeeping does not eliminate privacy obligations that may apply.

Questions can arise concerning notice, written consent, retention schedules, destruction of biometric information, third-party vendors, and security.

Because fingerprint timekeeping presents a concentrated set of legal and technological issues, it is distinct from fingerprint privacy generally. Net Law Advocates addresses biometric timekeeping separately within its biometric privacy practice.

Fingerprint Information Can Be Shared With Technology Vendors

The company requiring a fingerprint scan is not necessarily the only organization involved.

Employers, gyms, healthcare facilities, and other businesses may purchase biometric systems from outside technology companies. A vendor might provide the scanner, software, database, cloud infrastructure, or authentication service.

That can mean biometric information passes through systems operated by more than one organization.

Whether such a transfer is permitted depends on the law and circumstances.

Illinois BIPA, for example, restricts private entities from disclosing or otherwise disseminating covered biometric identifiers or biometric information unless a statutory condition applies.

Texas and Washington also regulate certain disclosures of biometric identifiers under their respective statutes.

The role of vendors is important because someone affected by a biometric privacy issue may recognize the employer or business that required the scan while knowing nothing about the company operating the underlying technology.

How Long Can a Company Keep Fingerprint Data?

Biometric information does not necessarily need to remain stored indefinitely simply because there was a legitimate reason to collect it initially.

Retention and destruction are therefore important components of biometric privacy.

Illinois BIPA requires private entities possessing biometric identifiers or biometric information to develop a publicly available written policy establishing a retention schedule and guidelines for permanently destroying the information.

Under the statute, destruction generally must occur when the initial purpose for collection has been satisfied or within three years of the individual’s last interaction with the private entity, whichever occurs first, subject to the statute’s terms and exceptions.

Other jurisdictions impose different requirements.

Retention can become particularly important in employment settings. A worker may provide fingerprint information for timekeeping over several years and then leave the company. Whether the biometric information remains afterward can depend on the applicable law and the organization’s practices.

Net Law Advocates addresses these issues more specifically through its planned content concerning biometric data retention and destruction.

Fingerprints Create Different Security Risks Than Passwords

Passwords are imperfect, but they have one significant advantage: they can be changed.

A person whose password is exposed can create a new one.

A fingerprint is different.

That does not mean a stolen biometric template can always be used as though it were a physical fingerprint. Biometric systems operate differently, and the security implications depend on how the data is generated, stored, and protected.

Still, the permanent nature of the underlying physical characteristic is one reason biometric information can warrant heightened protection.

Illinois BIPA requires covered private entities possessing biometric identifiers or biometric information to use a reasonable standard of care within their industry and to protect biometric data in a manner at least as protective as the way they protect other confidential and sensitive information.

When biometric information is exposed through a cybersecurity incident, the matter can involve both biometric privacy and broader data breach litigation.

What Happens If Fingerprint Data Is Exposed in a Breach?

A biometric-data breach presents a different issue from improper collection.

A company might comply with requirements governing the initial fingerprint scan but later fail to adequately protect the information it retained.

Alternatively, the same incident could involve several stages of potential concern: collection, storage, disclosure, and eventual exposure.

Information affected in a fingerprint-related breach might include the biometric template itself, information linking that template to an individual, account credentials, employee records, or other personal data maintained within the same system.

The consequences depend on what was actually exposed and whether the information could be used or linked with other data.

These incidents are addressed more directly through Net Law Advocates’ biometric data breaches content.

Illinois BIPA Provides Significant Fingerprint Privacy Protections

Illinois has played an important role in the development of biometric privacy law.

BIPA regulates private entities’ collection, possession, use, disclosure, retention, and protection of biometric identifiers and biometric information. The statute expressly includes fingerprints within its definition of biometric identifiers.

Among other provisions, BIPA addresses:

• Written notice before certain collection
• Written disclosure of the purpose and duration of collection
• Written releases
• Public retention and destruction policies
• Restrictions on selling or profiting from biometric information
• Restrictions on disclosure
• Standards for storage and protection

BIPA also provides a private right of action to people aggrieved by violations of the Act.

The statute permits recovery of liquidated damages of $1,000 or actual damages, whichever is greater, for negligent violations and $5,000 or actual damages, whichever is greater, for intentional or reckless violations, along with specified fees, costs, and other relief when the statutory requirements are satisfied.

Illinois amended BIPA in 2024 to address repeated collection and disclosure. Under the amended statute, repeated collection of the same person’s biometric information using the same method constitutes a single violation of the applicable collection provision for recovery purposes. Repeated disclosure to the same recipient using the same method is similarly treated as a single violation of the disclosure provision for recovery purposes.

The amendment is important because older discussions of BIPA damages may not accurately describe the law that applies today.

Fingerprint Privacy Laws Extend Beyond Illinois

Illinois receives substantial attention because BIPA provides individuals with a private right of action, but biometric privacy is not exclusively an Illinois issue.

Texas regulates the capture and use of biometric identifiers for commercial purposes and expressly includes fingerprints within its definition. The law addresses notice, consent, disclosure, retention, and destruction.

Washington also regulates enrollment of biometric identifiers into databases for commercial purposes and addresses notice, consent, disclosure, and retention.

Other states regulate biometric information through comprehensive consumer privacy statutes or other privacy laws.

The details vary significantly.

A requirement that exists in Illinois may not exist in another state, and a statute protecting biometric information does not necessarily allow individuals to sue directly.

For that reason, fingerprint privacy claims require an analysis of both the technology and the jurisdiction.

Does Fingerprint Collection Automatically Give You a Lawsuit?

No.

The fact that a business scanned someone’s fingerprint does not by itself establish a legal claim.

Fingerprint systems are widely used for lawful purposes.

A legal analysis may consider:

• Where the person lives or works
• Which biometric law applies
• What information the system generated
• Why the fingerprint was collected
• What notice was provided
• Whether consent was required
• Whether legally sufficient consent was obtained
• Who possessed or received the biometric information
• How long the information was retained
• Whether it was properly destroyed
• Whether it was adequately protected
• Whether the applicable law permits a private lawsuit

These questions can produce different results even when two people used similar fingerprint systems.

Evidence Can Help Establish How Fingerprint Data Was Handled

People often know that they scanned a finger but little about what happened behind the scanner.

Documents and other information can help reconstruct the process.

Depending on the circumstances, relevant materials may include consent forms, workplace policies, privacy notices, employee handbooks, timekeeping instructions, application screens, vendor information, emails, and communications explaining why fingerprints were required.

Someone who used a fingerprint time clock may also have records showing when the system was introduced and how frequently it was used.

Technical information can later help identify what biometric data the system created, where it was stored, which companies received it, and how long it was retained.

Those details can be important because biometric privacy cases often turn on the actual flow of information rather than the physical act of placing a finger on a scanner.

Fingerprint Privacy Is Part of a Larger Biometric Data Lifecycle

A fingerprint scan is only the beginning of the biometric-data lifecycle.

The information may be collected, converted into a template, stored, used repeatedly for authentication, shared with a vendor, retained for years, and eventually destroyed or exposed.

Different legal issues can arise at each stage.

Biometric data collection without consent focuses on whether the information was obtained with legally sufficient authorization. Biometric data sharing concerns disclosure to other parties. Retention and destruction requirements address how long the information remains after its original purpose has ended.

Understanding that lifecycle is often necessary to determine what happened to someone’s fingerprint information and whether applicable biometric privacy protections were followed.

Speak With Net Law Advocates About Fingerprint Privacy

Fingerprint technology can be convenient, but the biometric information generated through those systems can raise privacy issues that do not exist with ordinary passwords, cards, or identification numbers.

Whether someone has a viable fingerprint privacy claim depends on the technology involved, how the information was collected, the notice and consent provided, how the data was stored or shared, the jurisdiction, and the law that applies.
