Device Details


Overview

Name | Version: CopyProtectionTest Envelope Follower 1.1
Author: 11olsen
Device Type: Audio Effect
Description: A study of how to implement a copy protection scheme in a device. Uses the Envelope Follower Live 12.0.5 stock device as a test object for comparability.                                                                                                                                                           

- Device must be unlocked with a unique response key per machine
- key file is saved at the users documents folder
- Opening the editor does not reveal the main patcher
- unfreezing assets works, but the main patcher is an encrypted file

Conclusion: The Max C API allows us to act while a device is loading. We can freeze the device with an empty main patcher and an external inserts the appropriate patcher data, based on tested conditions and before the device even initializes. The possibility of encrypting embedded files such as abstractions, js files etc. was not explored further here.

Finally, the "weak spot" is that all max4live devices run in the same namespace, so it is possible to access and extract patchers of other loaded devices at runtime.

God forbid someone learn from your devices.
In a creator's community, this really isn't a very pleasant move.
Hi! I am currently working on something related to authentication for m4l devices, vsts, and other app/plugin types. I would love to talk to you about this/working together on the m4l side to get authentication going for device sellers. I am somewhat concerned about the internals being obfuscated upon authorization, but we can discuss. You can reach me at my username + gmail.
