What is a digital fingerprint?
A digital fingerprint is an identifying sequence of digits which is the result of
applying a mathematical algorithm to the complete content of a digital file. Digiprove
uses a proven algorithm called "SHA256" for this. The process generates
a 256-bit (64 character) calculated value, and the algorithm is so constructed that even
the tiniest change to a document will result in a change to its fingerprint.
The algorithm is a "one-way" process which means that it is not possible to
recreate a document from the fingerprint, and that it is not possible (without massive
computing power factors beyond those currently available) for a computer program to calculate
a document that will result in a given fingerprint.
