All companes are required to hold a copy of the share register at their place of prinicipal registration or via share registry. These are public cmpanies one has invested in so details of their ownership must be avaialble somewhere. If these were private organisation you could hide behind walls... Shareholders are legally entitled to view this at any time but may incurr a fee to do so. If someone wants to they can register to get given a copy of this (which I believe includes ones details as held by the companies share registry) but it can only be used for appropriate reasons which must be stated at the time of making the request. The company will provide the requested details but it will put legal statements in the provision of the details as to how they can be used.
This is why holding in company names is more fun as traceability becomes more difficult as then after the list becomes available they then need to pay a fee ontop of that to see whol the ultimate owners/beneficiaries are of the shares that are held.
