hi,
the way XOR operation works i.e 0 for duplicates is used the most.
A practical application that i know is , XOR is used for Forward Error
correction
for packet loss over a network. It works on the same principle like the
duplicate problem.
Another application that i know is for Error detection of transmitted
packets (which again works on the principle of duplicates).
i hope it helps.
