Data in PPT - Original or Duplicate?

"Original" is not (in any sense!) the counterpart to "duplicate".

You're confusing "original" with "unique".

I strongly suspect that you're also confusing "duplicate" with "syndicated": the difference between the two is explained in this post: Article Marketers – Lay the Duplicate Content Myth To Rest Once and For All - Internet Marketing and Publishing Blog

I write content that's both unique and original, publish it on my own site first, and then syndicate it as widely as I possibly can in relevant places that already have some targeted traffic I want to attract. (That's called "article marketing".)

Apart from "my own copies", none of what's subsequently published is "unique" but all of it is "original" (and that's why people want to publish it, of course: their readers and visitors and subscribers haven't seen it before. And it isn't "duplicate content", either: it's syndicated, just like a full-page article I read in today's Times newspaper, which it said in tiny print at the bottom had originally been published somewhere else, a while ago, but I hadn't read it before. And just like loads of the content on the world's leading news and sports websites, which is syndicated from places like Reuters and Associated Press: they wouldn't do that every day of the year if Google didn't like it, perhaps? ).
