Biometric PrivacySeptember 15, 2026

Your BIPA Consent Is a Checkbox. Section 15(b) Asks for a Release.

Most biometric deployments in Illinois have a consent flow. Far fewer have a written release that discloses a specific purpose and a length of term, stands alone from other paperwork, and is provably executed before the first template was ever captured — which is the thing the statute actually asks for.

Written Is Not the Hard Word. Release Is.

Compliance teams spend their energy on the wrong word. Whether an electronic record counts as written is a settled and unremarkable question — Illinois gives legal effect to electronic signatures, and a properly instrumented digital flow produces a stronger evidentiary record than a filing cabinet of paper forms ever did. Timestamped, version pinned, tied to an authenticated identity: that is a better artefact than a photocopy.

The word that does the work is release. An acknowledgement that you have read a policy is a different legal instrument from a release, and the statute pairs the release with a specific antecedent disclosure of purpose and term. A flow that presents a privacy policy link and a box reading "I agree to the terms" has produced an agreement to terms. Whether it has produced an informed, purpose-specific release is the question a claim will be about.

The Six Failure Modes

  • Sequence. The camera or scanner enrols first and the consent screen appears at the end of onboarding — so the collection preceded the release.
  • Bundling. One signature covers the handbook, the arbitration agreement and the biometric policy, leaving nothing that shows purpose-specific notice.
  • Generic purpose. "Security and business operations" tells a reader nothing about which uses are authorised and which are not.
  • Missing term. The retention rule sits in an internal policy nobody disclosed, so the term element is simply absent.
  • Pre-ticked or unavoidable. A box that is checked by default, or a flow with no path to decline, undermines the voluntariness a release depends on.
  • No version pinning. The policy text changed three times and the system stores a pointer to the current version, so nobody can reconstruct what any individual actually saw.

The last one is quietly the most damaging, because it is invisible until you need the record. Storing consent as a boolean and a date, with the disclosure text resolved at read time from whatever is live today, means every historical consent in the system displays the current language. Store the text, or at minimum an immutable version identifier with an archive of every version.

Where AI Deployments Create New 15(b) Surface

The classic Illinois fact pattern is a fingerprint time clock. The 2026 fact patterns are different in a way that matters for consent design: the collection is often incidental to a feature nobody framed as biometric. A meeting tool that builds voice profiles to attribute speakers. A support platform that adds voice authentication. A workplace safety model that derives gait or posture signatures from existing camera feeds. A verification vendor that performs a face match during onboarding.

In each case the product decision was made on a functional basis and the consent flow, if there is one, was inherited from the surrounding product. That is why the audit that matters is not a review of your biometric consent form — it is an inventory of every feature that derives an identifier from a body, which will be longer than the list your privacy notice currently describes.

What a Defensible Release Looks Like

  • A standalone document or screen, not a clause inside a longer agreement.
  • Names the identifier collected in plain terms — a fingerprint scan, a facial geometry template, a voiceprint.
  • States the specific purpose in operational language a reader could check a later use against.
  • States the term and the destruction trigger, consistent with your published retention schedule.
  • Names the vendor or category of recipient that will hold or process the template.
  • Uses language of release and authorisation, not of receipt or acknowledgement.
  • Provides a genuine decline path with a stated alternative, such as a badge or PIN.
  • Captures identity, timestamp and the exact version of the text presented.

The decline path is the item most often cut for operational reasons and the one that costs least to build. An alternative authentication method for the small number of people who ask for one is an ordinary product requirement. Its absence converts every consent in the system into one obtained under a condition of employment, which is a worse position to argue from than the handful of PIN users would ever have cost.

Questions From Illinois Deployments

Our workforce is unionised. Does the collective bargaining agreement handle consent?

It may route the dispute rather than resolve the obligation. Where a biometric timekeeping program falls within the scope of a collective bargaining agreement, federal labour law preemption has been applied to send the claim to the grievance machinery instead of to court, and that is a meaningful procedural difference. It is not a substantive exemption, it turns on the specific agreement and the specific bargaining unit, and it does nothing for non-union staff, contractors, temps or applicants at the same site. Build the release program anyway and treat the preemption argument as a defence you might have rather than a reason not to comply — it is significantly cheaper to obtain releases than to litigate about which forum decides whether you needed them.

Does BIPA reach photographs and video we already have?

The statute excludes photographs and writing samples from the definition of a biometric identifier, and that exclusion is doing less work than defendants often hope. The argument that succeeds for plaintiffs is that the identifier at issue is not the photograph but the scan of face geometry derived from it. So the compliance question is not whether you hold images — nearly every business does — but whether any system in your stack converts them into a template used to identify a person. A security camera recording is one thing. The same recording processed by an analytics module that clusters and recognises individuals is another, and that module is frequently a checkbox in a vendor console that someone enabled without a review.

How does the 2024 single-accrual amendment change the urgency here?

It reduces the multiplier, not the obligation. Before the amendment, a scan-per-shift theory meant a single employee over a few years could support an extraordinary number of claimed violations, and that arithmetic is what made the statute existential for some defendants. Recovery is now limited to a single accrual per person per method, which brings exposure back into a range that can be reasoned about. But the per-person figures remain substantial, the statute still carries a private right of action with fee shifting, and class sizes at a mid-sized employer are in the hundreds. Read the amendment as making remediation economically sensible rather than as making non-compliance affordable.

Our vendor's SDK handles the consent screen. Are we covered?

You are covered for the screen and not for the content, and the content is what fails. Vendor-supplied consent UI is written to be deployable across every customer, so it describes the vendor's product in general terms rather than your specific purpose, your term, or your retention rule — precisely the elements the statute requires be specific. Take the vendor's flow as a rendering engine and supply your own text into it. Where the SDK does not permit that, the honest finding is that the product cannot be deployed compliantly in Illinois without a wrapper, and that is worth knowing before rollout rather than during discovery.

What is the single highest-value thing to do this quarter?

Run the join. Take the set of individuals with a stored template or an enrolment record, take the set of executed biometric releases, match them on person, and compare timestamps. The output is a list of names in three buckets: release before collection, release after collection, and no release at all. That list is more useful than any policy review because it is specific, it is countable, it tells you where the gaps cluster, and it converts an abstract compliance worry into a remediation project with a finish line. Most organisations have never produced it, which is why most organisations describe their exposure in adjectives.

Read Your Own Consent Screen Back

Open the flow a new hire sees. Find the sentence that names the purpose, and the sentence that names the term. If you cannot point at both in under thirty seconds, neither can the person signing it, and that is the whole argument.

Fix the text first, the sequencing second, and the historical reconciliation third — because the first two stop the exposure growing while the third measures it.
