It has been suggested that the authorship tag will indicate to Google that you have the original content
Let's say "can indicate" instead of "will." It may well depend on other trust factors for that particular author and publiher, as well as the basic use of authorship mark-up.
Getting that kind of IP protection has been my experience in some market niches, especially with authors who lave built or are building a name for themselves. One site that used to outrank by scrapers and "collating" sites now outranks them, and fewer of them even get past the algorithm.
