Today I read an interesting news about a new kind of DRM.
This kind of DRM will not limit you on any device or app, you can read it anywhere you like. But once it is copied, the words & sentences in the book will differ, even change the meaning it should be.
So even getting the copy of the book, you are not able to read it fluently. Maybe in the original book, the man is dead, but in one copy, he is not. That will be interesting.
