Information stored in digital documents can be lost during transmission, migration, or when the storage medium breaks down or is corrupted. To ensure that the data has not changed, you can perform a digital fingerprint procedure. Up to a small margin of error, a digital fingerprint is unique to each document and therefore verifies the integrity (unaltered state) of the document.

Details
At every step, a cellular automaton rule is applied to the current state, and cells are dropped according to the compression technique being used.
This Demonstration presents some results of precision tests on research about finding an NKS way to generate fingerprints of electronic documents based on their contents, using the binary data of a document with an initial state and the result of computation as a fingerprint of this document.
