Christina Bonnington writes: “Last month, data from a wearable was entered as courtroom evidence for the first time.”

She asks herself when wearables data are admittable in court cases. “Data is data, whether it comes from a document, a drive or a device on your wrist. The key is authentication: Data must be legitimate, accurate, and related to the party in question. New technologies always undergo extra scrutiny, but if an attorney can prove those three criteria have been met, then wearable data is admissible. And there’s the catch. Wearables, by their very nature, can easily be taken off, worn by others, or jostled to create false readings. Thus, wearable data might be easy to undermine.”
