pyCANON, A Python library to check the level of anonymity of a dataset
Project description
pyCANON is a library and CLI to assess the values of the paramenters associated with the most common privacy-preserving techniques.
Authors: Judith Sáinz-Pardo Díaz and Álvaro López García (IFCA - CSIC).
Installation
We recommend to use Python3 with virtualenv:
virtualenv .venv -p python3 source .venv/bin/activate
Then run the following command to install the library and all its requirements:
pip install pycanon
Documentation
The pyCANON documentation is hosted on Read the Docs.
Getting started
Example using the adult dataset:
from pycanon import anonymity, report
FILE_NAME = "adult.csv"
QI = ["age", "education", "occupation", "relationship", "sex", "native-country"]
SA = ["salary-class"]
# Calculate k for k-anonymity:
k = anonymity.k_anonymity(FILE_NAME, QI)
# Print the anonymity report:
report.print_report(FILE_NAME, QI, SA)Description
pyCANON allows to check if the following privacy-preserving techniques are verified and the value of the parameters associated with each of them:

For numerical attributes the definition of the EMD (one-dimensional Earth Mover’s Distance) is used. For categorical attributes, the metric “Equal Distance” is used. |
