DataMasker

Data Masker masks data like customer names in a quick and deterministic way to enable demos or other purposes without easily giving away user information. It provides realistic looking data. Currently, it supports people names and generates data from an US census data set. Future versions may add support for additional data types. Suggestions welcome.

Caveat emptor: this is not meant to necessarily stand up to attacks by a determined adversary (in the cryptographical sense). While this is usually OK for purposes like live demos, you might want to consider another solution if you want to release a data set for public consumption. Use at your own risk.

Installation

Add this line to your application's Gemfile:

gem 'data_masker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install data_masker

Usage

Mask customer names

masked_name = DataMasker::MaskedName.new('John Doe')
masked_name.first_name
# => Cecile
masked_name.initial
# => Q
masked_name.last_name
# => Price
masked_name.to_s
# => Cecile Q. Price

Set salt

DataMasker.salt = 'NaCl'
masked_name = DataMasker::MaskedName.new('John Doe')
masked_name.to_s
# => "Louis P. Schrader"
