Imagine: Google itself could find proof of this, given that it's organizing the world's information. In fact, Google is one of the only entities that could actually 'prove' this out.
What would they do if they identified the time traveller? Locate him/her? Use his knowledge to further their plans? The knowledge may be potentially world-changing; whoever finds the traveller will be in a very powerful position.
Script idea: Eccentric googler finds proof of this and the company secretly finds the individual. Wild goose chase ensues. State actors get involved. I'd pay to see that.
Although Google is best placed to find any time traveller, the time traveller is even better placed to go back further in time and correct the situation to prevent the knowledge becoming widely known. Thus if time travel is possible, it's almost a certainty that Sergey Brin is a time traveller.
I would suspect that a time traveller might have all of the world's information searchable, locally stored in his implanted neural lace nanodevice. No Google searching necessary.

If this had already happened, would we even know?
