description: JSON-RPC methods to use for EEA-compliant privacy
<!--- END of page meta data -->
# Using EEA-compliant Privacy
When using [EEA-compliant privacy](../Explanation/Privacy-Groups.md), the group of nodes specified by `privateFrom`and `privateFor` form a privacy group and are given a unique
privacy group ID by Orion.
Enable the [`EEA` API methods](../../Reference/Pantheon-API-Methods.md#eea-methods) using the [`--rpc-http-api`](../../Reference/Pantheon-CLI-Syntax.md#rpc-http-api)
or [`--rpc-ws-api`](../../Reference/Pantheon-CLI-Syntax.md#rpc-ws-api) command line options.
Specify `privateFor` when creating the signed transaction passed as an input parameter to [`eea_sendRawTransaction`](../../Reference/Pantheon-API-Methods.md#eea_sendrawtransaction)
to create an EEA-compliant private transaction.
## Privacy Group Type
Privacy groups created when specifying `privateFrom` and `privateFor` are identified as type `LEGACY`
when returned by [`priv_findPrivacyGroup`](../../Reference/Pantheon-API-Methods.md#priv_findprivacygroup).
