This is of course obvious that we can never get full protection for apps that the program files have been given away. For server based things this is rather simple.
Tu, your work seems to be very interesting… Combined with other methods and technics it can provide a very good system. What I'm conserned is the actual performance that might go down. How is the decryption done - loading the code into memory and launching from there? Also, if in the future there will be other database engines available for Android, the data protection might become much easier also! To extend the idea of IMEI encrypted check keys, a rather good solution would also be to compile the app each time it is downloaded with unique keys hardcoded for identification purposes or make a number of apk's that are all different from inside and let the buyers download different version each time. This all can be 100% automated. The thing where the user has to authenticate himselt over network each time is impossible. Even the first time might be hard! I think the issue here is to make it a little bit harder than the cost of $10. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
