And he don't want that mine hardware buyer to resell it.

Even if the first part is possible i think this step will be difficult.
I expect it must be possible for the owner to move his equipment to another location. selecting another internet provider etc.
Or do you want to include a fingerprint reader, camera or other bio-metric sensor in the hardware (and software) where the owner needs to authenticate himself at regular intervals?
Possible solutions:
- Restrict who can get the mining reward. (This way anyone can mine, however this is only profitable for a select group.)
- Include in the rules of the coin that a specific constant changing key is needed for mining. Provide this key using a cloud server where the miners need to authenticate (and subscribe).
Even if it is technical done it will be difficult to convince anyone to buy/use a system with many restrictions.
