A graduate that once was a student of mine, has hired me as an advisor for her new digital health product startup. Her product, like most digital health products, will be gathering and analyzing potentially sensitive information about its owner's health and she's determined to do whatever is necessary to create a trustworthy product that keeps all data stored within it anonymous.
In her previous consultations with people that are more experienced in the design of digital products she was told that the data analysis could be done in a smartphone app. If the analysis determines that the best course of action is for the user to go to the doctor, they can always take their phone with them and help the doctor better understand what the patient's complaint is in their first visit thanks to the data collected.
