Since Copy and Paste is too easy and compute power is now ubiquitous, there need to be new rules that include generated data within publications: something constructed via computer from secret keys, that can be verified. (The minimum key size or other complexity measure would be required to increase over time, as always, to guard against easy cracking.) The hard part is coming up with something that can’t be just as easily replicated. If somebody is already willing to just copy an entire paper and change only the author’s name, they could just as easily “re-publish” with their own key in a crypto system and you have the same problem of original attribution (sure it’s “signed” now, by the plagiarizer!). The real problem in security is tracking time: how do you reliably know that event A preceded event B? In theory, you need a trusted time value, such that you can go to a server at any time and check it. For instance, a server where: given a value, it returns the time when the value was first recorded (ever-increasing). The value could be derived from content (e.g. hash of your entire paper, incorporating your own key).
