Biometric Data Privacy Litigation
Coverage from Computerworld, WebProNews, and others
Biometric data privacy litigation examines whether technology companies obtained meaningful consent before collecting or using identifiers such as voiceprints, how those identifiers are stored and shared, and whether they can be used in artificial-intelligence systems or other commercial technologies.
A major example involves Illinois lawsuits brought by journalists, podcasters, audiobook narrators, and voice actors against companies including Google, Amazon, Meta, Adobe, and ElevenLabs over alleged use of recordings to train voice models. The broader legal landscape also includes data breaches, re-identification, statutory notice requirements, settlements, and precedents under laws such as Illinois’ Biometric Information Privacy Act.
