[Lord of the Rings] Would it be possible to encase the One Ring in anything to prevent its power?

Either prevent or reduce the power of the Ring, or the ability for the ringwraiths to find it?

This is actually addressed in the books. The suggestions include:

1) Sailing it to the undying lands. This wouldn't work because the 'gods' of middle earth aren't to happy about dealing with mortal affairs. The ring is made of middle earth, and therefore it belongs their. This isn't their fight its middle earths.

2) Drop it into the middle of the ocean. There are 2 reasons this wouldn't work, and both are given. The first being Sauron is immortal, and oceans aren't, or "What lies at the bottom of the ocean may one day be a mountain peak". Also in the Silmarillion. When one of the silmarils is cast into ocean it is thrown back by Ulmo. 

3) Building something around it. Really no. The 'lore' (see skill) to build the ring is really only known by a handful of people who all left for the undying lands, and the rings they made were powerful but kinda knock copies of the real ring. So the only person who can build a box to contain it, built the ring... Well technically Morgoth probably could, but he's worse the Sauron.

4) Just keep hiding it in Rivendale. This doesn't work either. While the Nazgul have trouble entering Rivendale with elvish magic and all that. A entire army of orcs wouldn't, because well 25 million orcs verses 300-500 elves is going to be a wash. Because that's how numbers work.

Ultimately the fellowship was formed because Time was on Sauron's side. The longer it took to deal with the ring the easier it would became for Sauron to get it back. Sauron wanted his enemies to be weak, and divided. He wanted them to take a long time to deal with the ring while he quietly crushed Gondor and Rohan.
