Django Pseudonymization Example

This example Django app demonstrates two approaches to pseudonymizing personal data with masking functions.

Disclaimer

Our mask/unmask functions are intended for this example only, to enable demonstration of the application's handling of masking and unmasking. They do not sufficiently protect the data, as it is reasonably likely that someone accessing the data would be able to simply reverse the shifted characters, re-identifying users without any additional information present.
