Abstract
This paper is concerned with finding a fingerprint of a sequence.
As input data one uses the sequence which has been randomly mixed up
by observing it along a random walk path. A sequence containing
order exp (n) bits receives a fingerprint with roughly n bits
information. The fingerprint
is characteristic for the original sequence. With high probability
the fingerprint depends only on the initial sequence, but not on the
random walk path.
