EUID Overview for Private Operators

Own the process of generating EUIDs from personal data in a private environment.

Private Operators

Private Operators of EUID send first-party personal data to a secure environment for translation, and control the destinations for those identifiers. A participant that chooses to become a private Operator (previously known as closed Operator) can generate and manage EUIDs, running a EUID Operator service in a private environment.

Learn about what the EUID framework offers to private Operators, including benefits, hosting options, documentation and other resources, and how to get started.


Here are some of the intended benefits of participating in EUID as a private Operator:

  • You can maintain privacy-conscious workflows for your customer data to be encrypted and activated across chosen partners.
  • You can participate in EUID using your own first-party personal data without sharing it.
  • You have full control of resources, performance, and latency for EUID.
  • You can plan to minimize network hops with a service that can provide regional proximity.
  • You can implement processes and policies that you control, as opposed to taking part in a shared service.

For details, see The EUID Operator.

Hosting Options for Private Operators

If you choose to be a private Operator, several implementation options are available. You can do any of the following:

  • Use a cloud services setup. EUID supports hosting EUID in an enclave on the following cloud service provider (medium level of effort to implement):
    • Amazon Web Services (AWS)
  • Use your own machines to generate and manage EUIDs (greater level of effort to implement).
