OWIN

I have three role in my MVC5 application design. 1) administrator 2) Regularbloger 3) ParttimeBloger

Regularbloger Role has topic like 1) BlogTopic01 2) BlogTopic02 3) BlogTopic03
ParttimeBloger Role has topic like 1) BlogTopic14 2) BlogTopic15 3) BlogTopic16

Let say I create a user "abc@xyz.com" with role Regularbloger and want to assign BlogTopic02. So that whatever user "abc@xyz.com" write, it will only publish according to assigned BlogTopic02 section. He can't write any other blog section.
same goes for ParttimeBloger.

How can i do this using asp.net + MVC5 + Default authorization(Owin)
Thanks in advance.
