I am going to create a mobile book store for a very specific group of people. Since ePub is just compressed HTML, it's not secure enough. Anyone can access it if I extract the files to SD card. I don't want users copy the E-books around because I sell them for money.
I can parse the file and save it to a database. But I wondered if there is standard way for managing ePub DRM?
Thanks,

The Readium LCP DRM is on the market since 2017 and is now deployed in most countries. It is non-proprietary and does not break the accessibility of EPUB ebooks. It is replacing the obsolete Adobe DRM, step by step.
See https://www.edrlab.org/readium-lcp/ and more especially https://www.edrlab.org/readium-lcp/certified-apps-servers/ for more info.

Your best bet would be to use a DRM server solution. Adobe Content Server 4 is the leading system for this, used by Google Books, Barnes & Noble etc. though it can be a bit expensive to purchase a license and setup your own server. You can also use a SaaS service like EditionGuard to use it cost effectively, though you'll be using a shared environment in that case which may or may not fit your needs.
What kind of protection you are looking for?
From what i know you are trying to do something which is in the area of R&D plus challeging, at one side you will need to develop content encryption engine and other side a reader which will read encrypted content, these readers should also be supported in major os and mobile plateforms.
