Amazon has just made public their plans for their upcoming app store. The main difference the Amazon app store will have from the Android Market is that apps sold on the Amazon app store will have Digital Rights Management (DRM) to prevent piracy. The DRM system will constantly ping the phone’s store app which checks whether an app’s license is valid or not. Apps purchased from Amazon’s app store and protected by the DRM will only work when the Amazon app store is installed, so it’s going to be tougher to crack than simply uninstalling the Amazon app store. This added benefit of DRM might see developers flocking over to the Amazon app store, if they are afraid of their apps being pirated, but we’ll just have to see if Google does anything in response with their own Android Market. What do you think of DRM on your apps?
