Challenge Trial Judges Face When Authenticating Video Evidence in the Age of Deepfakes

By Taurus Myhand

The proliferation of deepfake videos has resulted in rapid improvements in the technology used to create them. Although the use of fake videos and images are not new, advances in artificial intelligence have made deepfakes easier to make and harder to detect. Basic human perception is no longer sufficient to detect deepfakes. Yet, under the current construction of the Federal Rules of Evidence, trials judges are expected to do just that. Trial judges face a daunting challenge when applying the current evidence authentication standards to video evidence in this new reality of widely available deepfake videos. This article examines the gatekeeping role trial judges must perform in light of the unique challenges posed by deepfake video evidence. This article further examines why the jury instruction approach and the rule change approaches proposed by other scholars are insufficient to combat the grave threat of false video evidence. This article concludes with a discussion of the affidavit of forensic analysis approach, a robust response to the authentication challenges posed by deepfakes. The AFA approach preserves most of the current construction of the Federal Rules of Evidence while reviving the gatekeeping role of the trial judge in determining the admissibility of video evidence. The AFA will provide the trial judges with the tools necessary to detect and exclude deepfake videos without leaving an everlasting taint on the juries that would have otherwise seen the falsified videos.
