pycanon 1.3.6

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

If you also want to install the functionality that allows to generate PDF files for the reports, install as follows

pip install pycanon[PDF]

Documentation

The pyCANON documentation is hosted on Read the Docs.

Getting started

Example using the adult dataset:

import pandas as pd
from pycanon import anonymity, report

FILE_NAME = "adult.csv"
QI = ["age", "education", "occupation", "relationship", "sex", "native-country"]
SA = ["salary-class"]
DATA = pd.read_csv(FILE_NAME)

# Calculate k for k-anonymity:
k = anonymity.k_anonymity(DATA, QI)

# Print the anonymity report:
report.print_report(DATA, 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.

More information can be found in this paper.

In addition, a report can be obtained including information on the equivalence clases and the usefulness of the data. In particular, for the latter the following three classically used metrics are implemented (as defined in the documentation):

• average equivalence class size

• classification metric

• discernability metric
