On-the-Fly Data Masking

What is On-the-Fly Data Masking?

On-the-fly data Masking is a dynamic data protection approach involving real-time modification of sensitive information as it moves through different systems and processes. Unlike static data masking, which applies irreversible changes to the entire dataset, it allows organizations to mask data dynamically based on user privileges and contextual requirements.

How On-the-Fly Data Masking works?

How On-the-Fly Data Masking Works?

This method involves intercepting data requests through different systems and applications, identifying sensitive data elements, and dynamically applying masking techniques to conceal or replace this information.

When a user requests access to data, the On-The-Fly Data Masking mechanism assesses the user’s permissions and the nature of the request. If the data contains sensitive information, the masking process triggers. Various masking techniques, including data anonymization, encryption, redaction, and others, are dynamically applied to ensure that sensitive information is concealed, altered, or substituted.

Difference between On-the-Fly and Dynamic Data Masking

Feature	On-the-Fly Data Masking	Dynamic Data Masking
Timing	Real-time, during data access/transfer	On-demand, at query execution
Data Modification	Data is masked before it is presented to the user	Data presentation is masked in query results
Data Location	Masked data is stored in a separate target environment	Unmasked data remains in the original database

Here are a few analogies to illustrate the difference.

Scenario 1: Magic Filter

On-the-fly data masking functions as an integral filter seamlessly incorporated into this pipeline. As the data moves through, the filter instantaneously masks sensitive details and stores the original data in the targeted database before presenting the masked data to the user. Dynamic masking filters only when a specific query is run on the database/filter and won’t store any copy anywhere.

Scenario 2: A chef with a secret recipe

The chef has two recipe books – one original and one with masked ingredients. When someone asks for the recipe with an on-the-fly query, the chef grabs the masked book and shows it. For dynamic masking, the chef has only one recipe book (the original). When someone asks for the recipe, the chef might cover up certain ingredients with his hand while showing them the rest.

Both scenarios present a masked recipe “in real-time” from the user’s perspective (the person asking for the recipe). However, masking occurs differently in this case, as it occurs on the fly with a separate masked copy and dynamically by manipulating the presentation at the time of request.
