[LotR] Does the Ring have any effect on someone who is unaware of its presence?

I'm imagining a hypothetical scenario where a skilled pickpocket plants the Ring in the pocket or satchel of an unsuspecting traveller, who then takes it the long road to Gondor and beyond, completely oblivious to the fact he's carrying Sauron's Ring or even any ring at all.

Frodo was able to relinquish the Ring freely and easily back at Bag End, so the corruptive Influence is not immediate. Aragorn and Boromir felt the Ring's call at a distance, but they knew both what it was and that their companion had it, so it had something to hook into in their minds. Faramir seemed to believe that the less he knew about the Ring, the less susceptible he would be to it.

I know it's very unlikely - but say this traveller had his own reason to go to Mount Doom and throw something unrelated into the volcano. If the Ring happened to be in that same pouch, would it prevent him from throwing it in without him knowing why?

Frodo's ability to relinquish the Ring at bag end is nothing short of extraordinary. It is something that sets him in particular, and to a lesser extent hobbits in general, as someone who might just have the capacity to resist corruption long enough to actually dispose of it. This is almost true, Frodo only succumbs at the very end, after months of exposure and in the place where the Ring's power is at its strongest.

So its very very unlikely, verging on ridiculous that the pickpocket would resist the temptation of keeping such a precious thing as the Ring for themselves, even if they didn't know it was the Ring of power. Smeagol didn't know what it was. He saw it in the possession of another, and that was enough to break him to drive him to kill his own kinsman and claim the Ring for his own.

Boromir is not an evil man, he is a good man, brave honourable and full of a genuine desire to protect his people and to defeat the growing evil that assails them. But he is still a human with rational fears, with human frailties. The Ring broke his resistance. It would have broken Faramir's and Aragorn's too, eventually. The pickpocket will prove much more easily snared. He doesn't need to kill someone, he already has the Ring in his grasp. And so the Ring already has the pickpocket in its grasp.

Even if the pickpocket did somehow manage to part with the Ring,  and plants it on the poor traveller as you suggest, the problem has not gone away. The Ring of power is not a passive object. It has a will of its own, and power enough to work that will.

It would eventually find a way to ensnare the pickpocket’s victim. All the while it would draw the nazgul to the poor traveller, especially if the traveller was foolhardy enough to venture into Mordor.

There will be no great diversion to draw the enemy's gaze from the traveller. 

They will find him. They will take the Ring. And he will beg for death before the end.
