Data Masking

Overview​

Data Masking is the process of concealing sensitive data by replacing it with fake characters or values, so that the data can still be used for certain purposes without revealing its original information.

Unlike encryption or tokenization, data masking does not use a key or algorithm; instead, it replaces important data elements with disguised characters, such as asterisks (*) or other placeholders. Because masked data cannot be restored to its original form, this feature provides additional protection against unwanted access or leakage.

Data Masking Functions​

The Data Masking menu serves to:

  • Conceal sensitive information from the user's view.
  • Restrict access to original data based on access needs.
  • Reduce the risk of information misuse by unauthorized parties.
  • Support the implementation of data protection policies within the organization.

Data Masking Uses​

The Data Masking feature can be used to:

  • Protect personal data displayed to users.
  • Present data securely in both operational and testing environments.
  • Helps meet privacy needs and compliance with data protection regulations.

How Data Masking Works​

The Data Masking process is carried out by replacing part of the original values using a predetermined masking pattern.

The process is as follows:

  1. The original data is received by the TAKAKRYPT service.
  2. The system identifies the portion of the data that needs to be disguised.
  3. Certain characters or values are replaced using the predetermined masking pattern.
  4. The masked data is displayed to the user or application.
  5. Sensitive information is not visible even though the data structure remains recognizable.
