A California law firm has filed a class-action lawsuit against Fidelity National Information Services (FIS) and one of its subsidiaries over an incident involving the potential compromise of personal data belonging to 8.5 million consumers. The lawsuit was filed last week in federal court for the Central District of California. It does not seek specific damages, but it accused FIS and Certegy Check Services, the subsidiary involved in the breach, of negligence, invasion of privacy and breach of implied contract. The breach in question was disclosed by FIS in July and involved a senior database administrator who illegally accessed and downloaded millions of consumer records.”]
