Sorry, but I must disagree. Let us say that T is the original page and F
(false) is the copy.

If F = T + A where A is some extra content, then you have problems

If T = F + A then your assumption is correct

If T = F you can rely on links (acknowledgements)

What would you do when:

F = T1 + A + T2 + B + T3

Or even worse:

F = T1/2 + A + T2/2 + B 

To a black hat SEO it would be no problem to automate this and deceive the
search engines. it is much easier to carry out a robbery than it is for the
police to spot the crook in a town of millions.
