    Brandeis "Right to Privacy" Law Review Article

    The Right to Privacy (or “the right to be let alone”) is a law review article published in the 1890 Harvard Law Review. Written primarily by Justice Louis Brandeis (but credited to both Brandeis and Samuel Warren), it is one of the most influential essays in American legal history and is considered the first publication in the U.S. to argue for a right to privacy. The authors charge that “instantaneous photographs and newspaper enterprise have invaded the sacred precincts of private and domestic life” and seek to “consider whether the existing law affords a principle which can properly be invoked to protect the privacy of the individual.”

    Privacy Torts

    In 1960, William L. Prosser, a well known legal scholar of the time, published the article Privacy. In the article, still considered influential in the field of privacy law today, he outlined four torts that would allow someone whose privacy was violated in one of those four ways to sue the perpetrator for damages. These torts are still used today:

    • Intrusion upon seclusion or solitude, or into private affairs;
    • Public disclosure of embarrassing private facts;
    • Publicity which places a person in a false light in the public eye; and
    • Appropriation of one’s name or likeness.

  • 2023 and Beyond

    Artificial Intelligence (AI) and Innovative Technologies

    2023 was the breakout year for Generative AI and AI tools are becoming ubiquitous across industries and organizations, including higher education. Processing vast amounts of information using these tools poses risks of exposing sensitive personal information, while algorithms and automated decision-making introduce inherent challenges with legal, individual, and societal impacts.

    In April 2021, the European Commission proposed the first regulatory framework for AI. As of January 2024, the European AI Act is waiting to be formally adopted by Parliament and Council to become EU law.

    In the United States, there is no comprehensive federal law governing AI use. Specific applications of AI, such as autonomous vehicles or drones, are regulated by a patchwork of federal, state, and local regulations. The Federal Trade Commission (FTC) is actively examining AI and algorithmic transparency under its authority to prevent deceptive or unfair business practices. Legislations including the Algorithmic Accountability Act and the Commercial Facial Recognition Privacy Act have been introduced in Congress, but are yet to be enacted into law. Several states are forging ahead with their own AI regulations. 

    This evolving regulatory landscape reflects the ongoing efforts to balance the benefits of innovative technology with the need to protect privacy, security, and other democratic values. (This summation was written in collaboration with U-M GPT)
