A proposed class action lawsuit alleges that Walmart's AI voice system unlawfully collects biometric voiceprints from Illinois residents without proper consent or disclosure, violating the Illinois Biometric Information Privacy Act (BIPA). The plaintiff claims the system captures these unique identifiers during customer service calls to local stores. The lawsuit highlights risks associated with the unauthorized collection of biometric data, including potential use by fraudsters to create false digital identities.
A proposed class action alleges that Walmart's AI voice system captured biometric voiceprints from Illinois residents who called local stores without first obtaining meaningful consent or explaining how the biometric data would be retained and deleted. Plaintiff Amber Smith said the system captured her voiceprint during two calls in December 2025 and one in July 2026.
Domain classification, causal taxonomy, severity scores, and national security assessments were LLM-classified and may contain errors.
AI systems that memorize and leak sensitive personal data or infer private information about individuals without their consent. Unexpected or unauthorized sharing of data and information can compromise user expectation of privacy, assist identity theft, or cause loss of confidential intellectual property.
The incident involves an AI system capturing and storing sensitive, non-public biometric voiceprints of callers without their explicit consent or knowledge.

The privacy risk was caused by Walmart's intentional corporate decision to deploy the AI voice system to collect biometric data without obtaining proper user consent.
Walmart faces a class action lawsuit in Illinois for allegedly collecting customer biometric voiceprints without proper consent via its AI customer service voice system. The incident represents a domestic corporate privacy and regulatory compliance issue with negligible implications for national security.
The AI system functions as an automated voice assistant that handles customer service phone calls, interacting with users to route calls or resolve inquiries.
Limited Risk: The system is an automated AI voice assistant (chatbot) which carries transparency obligations to inform users they are interacting with an AI, which Walmart allegedly failed to do.
The system is deployed as an automated AI voice assistant to handle customer calls, while utilizing voice recognition capabilities to capture voiceprints for fraud prevention.
The legal complaint clearly outlines the mechanism of the AI voice system, the specific biometric data collected, and the regulatory framework (BIPA) being violated. There is little ambiguity regarding the core privacy allegations.
None
Technology
Automated AI Voice System
AI system automatically captures and processes voice data during phone calls.
Voiceprint Extraction Tech
Technology extracts unique biometric voiceprints from user speech.
Data Inputs
Biometric Voiceprint Data
Sensitive biometric identifiers are collected directly from caller audio.
Unfiltered Voice Capture
System captures voice data without pre-filtering for biometric consent.
Human Factors
Unaware Consumers
Callers are unaware that their voiceprints are being captured and stored.
Involuntary Data Surrender
Customers are forced to unknowingly surrender private biometric data.
Process and Methods
Inadequate Disclosure Process
Privacy policy disclosure is insufficient for proper notice and consent.
No Consent Mechanism
System lacks a process to obtain active consent before voice collection.
Missing Retention Schedule
No written policy exists detailing the retention and deletion of voiceprints.
Management
Prioritizing Fraud Reduction
Management deployed the AI voice system to reduce fraud without compliance.
Inadequate Risk Assessment
Failure to properly assess legal risks of biometric data collection.
Regulatory Environment
Strict BIPA Requirements
Illinois law mandates strict notice, consent, and retention schedules.
Inadequate Legal Compliance
Walmart's practices failed to comply with state biometric privacy laws.
AI system involved
Identified by automated extraction; can differ from the alleged developers above.
