Data Broker Consumer Privacy Violations

Lieff Cabraser is investigating the wide-scale privacy invasions of consumers by “data brokers.”

A data broker is a business that knowingly collects and sells to third parties the personal information of consumers. Data brokers monitor, track and follow people in virtually every aspect of their lives. The behaviors, movements, social relationships, interests, weaknesses and most private moments of billions are now constantly recorded, evaluated and analyzed in real-time. This exploitation of personal information has become a multi-billion dollar industry that is based on invading consumers’ privacy.
