zanon 0.1.3

A module for z-anonymity

zanon

A module to anonymize data streams with zero-delay.

When instantiating the zanonymity object the constructor receives a $\Delta t$ in seconds and a value for $z$.

The anonymize() method accepts a string in the form of a triple $(t,u,a)$ - meaning that at time $t$ a user $u$ exposes an attribute $a$ - and a file object.

If the triple exposes an attribute that has not been exposed by other $z$ - 1 users in the past $deltat$ the triple is simply ignored. Otherwise, the triple is printed on the file object.

example of usage

from zanonymity import zanon

file = "trace_products.txt"
deltat = 3600 #in seconds
z = 20

z = zanon.zanon(deltat,z)
f = open('simulation_output.txt', 'w+')

for line in open(file, 'r'):
	z.anonymize(line,f)

f.close()
