I may need to to have a tape 'securely' transported from the East Coast to the West Coast. I'll need to guaranty arrival and that is was not tampered with, opened etc. Has anyone does this? How did you do it?

Kirk:

Do you need to protect the tape? or the data?

That is, if the data arrive without change of content such that a bit-level comparison revealed no difference, would it matter if it arrived on a physically different tape? That's intentionally extreme, but I hope it illustrates the difference between 'tape' and 'data'.

Does it matter if anyone sees it if it's encrypted strongly enough? If hashes from two different algorithms are generated and both match on the receiving side, is that evidence of no change? Is this equivalent to legal 'chain of custody' or something different? (More stringent?)
