__NOTOC__
Persistent identifiers like Hashed email address (HEM) or/and Unified Identifier 2 (UID2) can be passed for the purpose of enhancing Digital Content and Ad Ratings products through the various integration solution we have like Nielsen Digital SDKs, Cloud API, Server-to-Server, DAR pixel tags or DAR.js Javascript tags.
Currently persistent identifiers can be passed in the following formats:
===== Hashed Email(HEM) =====
Please use the parameter that matches your hashing algorithm. For example, if you are using sha256 to encode the email address, then use the parameter name hem_sha256.
{| class="wikitable"
|-
! Name !! Description !! Available Tag Parameter
|-
| Hashed Email || User’s email address that has been run through a hashing algorithm (e.g. SHA256, MD5, SHA1) to create a unique 32-character hexadecimal string. || hem_sha256''&nbsp;(preferred)'' <br> hem_md5 <br> hem_sha1
|}

Eg. hem_sha256=tMmiiTI7IaAcPpQPFQ65uMVCWH8av9jw4cwf/F5HVRQ=

===== Unified ID =====
{| class="wikitable"
|-
! Name !! Description !! Available Tag Parameter
|-
| Unified ID 2.0 || An identifier based on a user’s verifiable PII (e.g. hashed email). UID2.0 was initially created by The Trade Desk (TTD) and is now managed by Prebid. || uid2
|-
| Unified ID 2.0 Token || Encrypted Unified ID 2.0 || uid2_token
|}

Eg. 
uid2=MTKVpUAzwYAPnHrtfE0wlINOMzhU7UUEjjVdCdRu63k=
uid2_token=AgAAAAPFR0zA5ogv/yaAPiUsAdZPsfqS8QlDSGxAB+rr8yekFs3AjLYVk5qqqiyV2XHbSuwzHmxSlLeQeKQI1mp015jsNnpX5/xGgXldcgVz+gFnyh3T8/3agMwRmyrhCxG4oH2C7

== SDK Integration ==
In case of mobile or browser SDK integrations, the 1st party identifiers can be passed in the SDK initialization call. For example:

===== Android AppSDK Integration =====
{{Initialization_of_App_SDK_object_through_a_JSON_object}}
<br><br>

===== IOS AppSDK Integration =====
{{iOS_init_example}}
<br><br>

===== Browser SDK Integration =====
{{example_bsdk_init}}
