A legal case in Canada is breaking new ground by using data collected from a Fitbit to assess the relative fitness of a person making an injury claim. The law firm representing the claimant is hoping to demonstrate that their client, who used to be a personal fitness instructor, is not nearly as active as she would have expected to be given her former profession.
The data from the Fitbit is being processed by a company Vivametrica. They will compare the collected data from the claimant with population health data and judge whether it is normal for someone of her former profession.
Although this case raises a number of legal and practical issues about the use of activity tracking data in court, it has opened the floodgate of speculation about how this data could be used in future legal cases. In this particular case, the data will assist the lawyers, presumably in conjunction with expert opinion, with accurately determining what this particular person’s current level of activity is. They will then hope to show how it is significantly less than it should be if it weren’t for the injury she suffered.
Where we are far more likely to see activity data being used in court is for the purpose of discrediting claims of injury which are contradicted by activity data. Attorney Neda Shakoori gives an example scenario of someone claiming injury as a result of a motor vehicle accident whose data from their 5 mile runs is uncovered and used by the defendant’s legal team.
In these cases, the data being used is simple step counting. In the future however, we will be wearing devices that will be able to measure a range of physiological activity continuously. Coupled with GPS data that records the wearer’s location at any given time, the physiological data will document in detail what a person was doing at any given time. It will be difficult to claim for example, that you were relaxing at home watching the television when the data actually showed at the time you were experiencing raised heart rate, faster breathing and elevated levels of stress.
In fact, this data, if it were accessible to criminal investigators, could actually be used to help in tracking possible suspects by placing them at the scene of a crime with an appropriate “physiological profile” of someone committing a crime.
The courts in various jurisdictions will be determining the appropriate use of this data and will need to overcome issues of privacy and in the US in particular, with aspects of the American constitution. The 5th Amendment for example provides protection against self-incrimination and so the question is whether fitness data could be ruled inadmissible on those grounds.
In practical terms, it may also be hard to argue that the data being presented in court was actually that collected from a specific individual and that it represents a true record of that person’s activity. It would be extremely easy currently to produce data that reflected a specific pattern of activity. It is also difficult to prove that it was a specific individual that was wearing the tracker when the data was recorded. Eventually however, it may be possible to actually to tie this data unequivocally to a specific individual using their heartbeat data as biometric identification.
Using heartbeats to identify an individual is something that Apple has considered and has even filed for a patent that uses heartbeat data to identify a person in the same way that they currently use fingerprints to unlock mobile devices. In fact, Nymi is already using this approach in a device that will provide access to computers, cars and homes.
Another type of wearable that will increasingly play a large role in legal cases are cameras such as the Narrative Clip that are constantly taking photos. Like activity trackers, the evidence produced by these devices may end up being used to save the wearer in a court of law or damn them.
What the legal case in Canada has highlighted more than ever is the fact that policy and the law is going to struggle to keep up with how rapidly technology is changing what we can now do in terms of evidence. For users of wearables, it is another aspect to consider as we move to completely documented lives.
