might be that information is informative when it is shared as an open epistemological system within the universe of discourse. So-called 'secret' or 'encrypted' or 'secure' information is inherently corrupt for the same rationale that those who use it think it is secure. While the actual symbols of the information-set -might- be recoverable at a specific destination, the meaning of those symbols will have changed by virtue of their selective value to the sender and receiver, and by the necessary transition into a meta-message during transit. Such meaning, like the blink of an eye interrupting a photon-stream, is never fully recoverable, and neither active-encrypted nor passive-restricted secrets cannot thus be fully trusted. Oversimplified, if 'X' is an information-set, and it is predicated with 's' as a secret-set, then the message-packet becomes 'Xs'. Either retention from public access or filtering within secure media will decay the meaning of the message X. Put another way, one cannot literally walk in the same stream (of information) more than once because it is under constant forces of change. More accuracy is retained by numerous 'witnesses' to the data when the message-packet is under constant review and surveillance. This is not logically possible at the quantum/discrete-photon level without entanglement "entrapment" of bits.

In application, banks which buy into security at this level cannot know whether the data is uncorrupted because aside from the stated problem, there is the time-based uncertainty of the symbolic value of money. This is another discussion, and I have a sub-prime mortgage byte investment to sell you.
