Continue : If you have people enter the room randomly and without knowing the order of entrance that will solve the problem. That could be done (without third party) if you have one of the participants pick people at random to go there and then taking the last one.

comment Secret santa problem
The first remark is true. There's a chance of this happening. I can't calculate it now but I suppose that it is lower than the all random one. About the second one. Well what information does he gain ? Someone (1,2,3,4, ,6,7,8 (if sequential remove 6,7,8)) drew someone else (1,2,3,4, , ,7,8). The one exploit I could see is if the second to enter draws from the same box the first drew, or sees that he (or his partner) is drawn by 1. If you have everyone choose random box, random draw (repeat if empty) and look at nothing else then there is a low chance that anyone would get enough info.
