Obfuscate (Productivity)

Synopsis

Replaces all nominal values and attribute names by random strings.

Description

This operator takes an ExampleSet as input and maps all nominal values to randomly created strings. The names and the construction descriptions of all attributes will also replaced by random strings. This operator can be used to anonymize your data. It is possible to save the obfuscating map into a file which can be used to remap the old values and names. Please use the operator De-Obfuscator for this purpose. The new example set can be written with an ExampleSetWriter.

Input

example set (Data Table)
This input port expects an ExampleSet.

Output

example set (Data Table)
original (Data Table)
The ExampleSet that was given as input is passed without changing to the output through this port. This is usually used to reuse the same ExampleSet in further operators or to view the ExampleSet in the Results Workspace.

Parameters

obfuscation_map_fileFile where the obfuscator map should be written to. Range: filename
use_local_random_seedIndicates if a local random seed should be used. Range: boolean
