Question How to Protect Asset Bundle in AR Application

Hello All,

We have building AR mobile application in that we are downloading asset bundle from cloud for viewing.
That part is working fine but our concern is related to security of asset bundle.
The asset bundle which is getting downloaded is being stored in the local cache of mobile & also we can open that asset bundle in unity also.

Please help me how can we protect the asset bundle which is getting downloaded in the mobile applicaiton.

Thanks
