Just trying to confirm if data is, or if there is an option to keep data encrypted on the Android device when using the interviewer application.
Data stored in internal storage
Other apps and user cannot get access to this data. Unless device is unrooted.
As Victor said, the data on a tablet is stored in the internal storage that makes that data secure. The data is also protected by Android user account protection.
However, we will be releasing an additional layer of encryption on a tablet for our data.
As I wrote in my last post in this thread, we plan to release a version of Survey Solutions with the enhanced data protection and data encryption features at around December 3st.
We would be interested to know the security requirements for the surveys conducted by RTI. If we know your requirements we could implement them in the upcoming release.
