Uber to trial recording audio of rides - what could possibly go wrong?

News in that that Uber is to trial audio recording of rides in Brazil and Mexico in a move that could see it rolled out to other territories.

The reasoning behind the move is that it might increase driver and passenger safety and help to arbitrate in disputes or criminal acts during the journey. There is logic to this, but there are also numerous concerns with the trial:

- Privacy: concerns over your personal conversations being recorded and stored on Uber's services
- Data: the audio would be recorded on the driver's device and then passed as encrypted files to Uber -  what about the cost of the data on the driver's data plan?
- Encryption: this is a minimum but what if the recordings are hacked in a data breached and the voice recordings and voice print of the users are used for nefarious purposes
- Opting-in: what about your consent to have your voice recorded? Can you opt-out

On the face of it, it looks like a legal minefield and raises all kinds of privacy concerns even if the intention behind it is a positive one.
