Modern life requires all Americans to trust that companies, financial institutions, and medical providers are taking all reasonable steps to protect our most private data.  When a data breach results from intentional or reckless behavior, the company or organization storing it must be held accountable.

Invasion of Privacy and Unauthorized Disclosure

Consumers regularly entrust large companies with their confidential financial data.  These service providers, whether they are insurance agents, accountants, or investment counselors, have a fiduciary duty to their clients.  Medical information is another form of sensitive personal data that consumers rely on doctors, hospitals, and insurance providers to maintain in confidence.  However, even within the last few years, numerous multinational corporations have disclosed this sensitive data through unauthorized, unsecured publication on the Internet or, in some cases, through security breaches by internet hackers.  These instances of unauthorized disclosure are civilly actionable, as consumers can become susceptible to identity theft.

Many internet-based companies may be liable to consumers for the unauthorized use of personal data.  Unlike situations of unauthorized disclosure, these companies manipulate user data to track and profile customers for targeted advertising and other profit-driven tactics, in some cases even selling the personal data to third parties.  While companies typically provide disclaimers requesting authorization for the use of personal data, in some instances these authorization requests are misleading, confusing, or even entirely absent.  These invasions of privacy can affect millions of consumers, even if the affected consumer is not a member or subscriber.  Our attorneys are committed to protecting consumer rights on the Internet and promoting the privacy interests of the general public, taking on the most powerful web-based corporations to fight this unauthorized usage of personal data.
