Information Recovery From A Randomly Mixed Up Message-Text

چکیده
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.

With high probability the fingerprint depends only on the initial sequence, but not on the random walk path.
