How to protect images.xcassets from theft?

Question

I mainly develop an application containing several copyrighted images (these images belong to the society I work for), and I am looking for a way to protect or block users from accessing these images (for example: via iFunBox or iFile on malicious devices). I read about TexturePacker, and that’s exactly what I was looking for: a kind of encrypted content protection to make data theft more difficult. Unfortunately, I use simple SpriteKit for development, and I cannot use this infrastructure. Any clue?

The xcassets file encodes the images in a binary so that you cannot just view them through the file browser. However, when performing a quick Google search for "Assets.car extract", there are many tools to decode an available file. Regardless, someone can always find a way to access your assets if they really want to (i.e. Read directly from memory). Less tech savvy users can even simply capture the screen to get your assets (albeit not original files). Therefore, you need to find out how much development time you really want to spend on minimizing this.
