The law bans companies from collecting a person’s biometric information unless they first provide notice and obtain the person’s written consent. In 2017, Apple began syncing photographs and associated data across multiple Apple devices, if those devices were logged into iCloud with the user’s Apple ID. Plaintiffs claim that this data is biometric information under the Illinois law, and that the company collects and stores the biometric information on its servers. The company has said the Photos app has privacy safeguards, so that the numerical vectors it uses to organise photo albums cannot recreate a face and are not inherently linked to a person’s name or identity. In June an Illinois judge ruled that consumers had met the requirements to pursue a class action.
