Document fingerprint generator

Project description

Fingerprint -- Document Fingerprint Generator

Fingerprint is a signature of the document. In particular, it is a representative subset of hash values from the set of all hash values of a document. For more detail, please consider taking a look at Winnowing: Local Algorithms for Document Fingerprinting (specifically Figure 2).

Fingerprint Module Installation

The recommended way to install the fingerprint module is to simply use pip:

$ pip install fingerprint

Fingerprint officially supports Python >= 3.0.

How to use fingerprint?

>>> import fingerprint
>>> fprint = fingerprint.Fingerprint(kgram_len=4, window_len=5, base=10, modulo=1000)
>>> fprint.generate(str="adorunrunrunadorunrun")
>>> fprint.generate(fpath="../CHANGES.txt")

The default values for the parameters are

kgram_len = 50
window_len = 100
base = 101
modulo = sys.maxint
