Pseudonymization Release Guide: Restoring Original Custom Attribute Values

This guide explains the procedure for releasing attribute values that were pseudonymized during the digital badge issuance process and viewing the original information again. We also provide access permission criteria and safe data management procedures.

Introduction to Pseudonymization Release

• “Pseudonymization” is a feature that masks and displays personal information such as the name and date of birth included in a certificate.
• When a third party requests to view the pseudonymized information included in a certificate, the recipient can approve or reject that release request in the certificate view request notification message.
  • Example) A case where a recruiter requests a pseudonymization release to check the recipient’s certificate information.

Pseudonymization View Request

• When a third party requests to view pseudonymized information, a view request notification message is sent to the recipient.
• In the notification message, you can choose {Approve} or {Reject} for the pseudonymization release.

Approving a Pseudonymization View Request

• If the recipient approves the request, the requester can view the pseudonymization-released information for 24 hours from the time of approval.
• Once 24 hours have passed, it is automatically restored to the original pseudonymized state without any separate notification.

Rejecting a Pseudonymization View Request

• If the recipient rejects the pseudonymization release request, the requester can only view the pseudonymized information.
• In this case, the masking is not released, and the requester can later request again for the same certificate.

* If phone verification has not been completed, the notification is sent by email.
