ReadingÂ Japanese govt: Use operator-run app stores, not Google Play reminded me of an app that I use a lot, but who’s permissions are a cause for concern: Ocado on the Go.
The Ocado app wants to use your phone’s video camera, so it can scan bar codes. This is a legitimate requirement: there’s no way to do this using an intent. The trouble is, this is true for any real time use of the video camera. E.g. Samsung are planning to implement scrolling by tracking your eye movement. The video camera is the last thing you want to give unmoderated access to. This is really something for Google to fix.
The Ocado app wants to save your delivery slot in your calendar. Again, this is useful but I can’t see why this isn’t done with an intent, and hence requires no permissions. Instead, the app asks for for permission to ‘add or modify calendar events and send email to guests without owners’ knowledge, read calendar events plus confidential information’. That sounds like something I’d only want Google to be able to do, right? This is one for Ocado to fix: I know the user experience will be compromised a bit, and there’s someone in marketing jumping up and down, but this really is a race to the bottom: if Ocado feel they can justify having this permission, and everyone copies them, Android users won’t be able to reject apps based on their permissions, and hence won’t be able to rely on having a secure calendar.
Actually, Ocado need to fix their app, but where is the incentive? Only Google have an interest in the security of the platform as a whole. Perhaps if Google gave apps a security score calculated from the requested permissions, and made it prominent on the Play store? I’d be tempted to charge for listings on the store, based on the security score. Otherwise, we are back to using only closed stores with vetted apps.
It’s not even possible to fix this using something like Cyanogenmod. The app just uses an API which a user can’t effectively moderate.
Not content with that, Ocado on the Go asks for the following additional permissions for no apparent reason:
I don’t think it will be long before APTs areÂ targetingÂ Android developers, with the intent of adding malware to widely used applications. APTs can target developers watering holes, and then seek out the Android SDK, and applications on developers hosts. Then it’s not a question of trusting Ocado’s intent, but the competence of their network security manager.
