Question

The receipt Apple returns from a purchase does not include the iTunes account information of the user that purchased the content and there also doesn t seem to be way of having Apple verify if a given device UUID belongs to an iTunes account.

Is there anyway to implement a secure DRM system that allows users to purchase content once and be able to use the content for all on all the devices associated with their iTunes account?

If there s a way to replay a receipt or spoof information, I don t consider it a secure DRM system.

This question, and subsequently, my answer and its comments, sparked my curiosity about this.

Answer 1

I think apple doesn t want you to modify their DRM system or make a new one... You could Tell Apple about the problem and they may be able to help you.

The receipt wouldn t include any account/private information since the receipt information can be read by most apps, it wouldn t want that information going around to anyone.

All I could think is to ask the user to reenter their id and/or password.
