DB generated keys should never be the same so I don't think you would run into this problem. If you are creating your own keys, then you should make sure you never use an existing keys. > > 2.

If you want to restrict access to shared data or restrict the ability to synchronize data for offline usage, the code should be implemented on the serverside such that when a user tries to sync they will send a request to sync and the server will validate/respond with data or invalidate/respond with a denial. -Ben
