I downloaded a docker image from a third party. It's an annotation tool. To use I need to run that image, sign up and upload my data to annotate. Although it can be run without internet. Problem is I can't understanding whether the image provider get access to my data or not. Is there any suggestion? Thanks in advance.
1.Check the network connection of the container for heartbeat or C&C.
2.Check that the upper layer of the mirror is reliable, and if so, just make sure that the additions are safe.
