A bill co-sponsored by Colorado’s U.S. Cory Gardner to study the problem of “deepfakes” passed the Senate unanimously Friday.

Digital content forgeries, as defined by the legislation, use artificial intelligence and machine learning to fabricate or manipulate digital content with misleading intent.

“Deepfakes can be used to manipulate reality and spread misinformation quickly. In an era where we have more information available at our fingertips than ever, we have to be vigilant about making sure that information is reliable and true in whichever form it takes,” Gardner said in a statement.

The Deepfake Report Act requires the Department of Homeland Security within one year to produce an assessment of the technologies and the nongovernmental entities or foreign governments that are originating digital content forgeries.

A similar bill in the House is awaiting action by the Energy and Commerce Committee.

Altered viral videos featuring U.S. House Speaker Nancy Pelosi and Facebook CEO Mark Zuckerburg drew attention this year to the ease of using footage of public figures to create a false impression. California and Virginia both passed legislation this year that included deepfakes under the category of outlawed revenge porn.

California also prohibited the posting of deepfake videos meant to discredit politicians within 60 days of an election.

CBS4 reported in July that the University of Colorado-Denver is involved in a Pentagon research project to create algorithms for detecting deepfakes.
