Delivering relevant digital experiences requires having a complete understanding of your customer. This is made more difficult when your customer data is fragmented across disparate systems, causing each individual customer to appear to have multiple “identities”. Adobe Experience Platform Identity Service helps you to gain a better view of your customer and their behavior by bridging identities across devices and systems, allowing you to deliver impactful, personal digital experiences in real time.
Each day, customers interact with your business and establish a continuously growing relationship with your brand. A typical customer may be active in any number of systems within your organization’s data infrastructure, such as your eCommerce, loyalty, and help-desk systems. That same customer may also engage anonymously on any number of devices. Identity Service allows you to piece together a complete picture of your customer, aggregating related data that might otherwise be siloed across disparate systems.
Consider an everyday example of a consumer’s relationship with your brand:
Mary has an account on your eCommerce site where she has completed a few orders in the past. She typically uses her personal laptop to shop, where she logs in each time. However, during one of her visits she uses her tablet to shop for sandals, but does not place an order and does not log in.
At this point, Mary’s activity appears as two separate profiles: her eCommerce login and her tablet device, perhaps identified by device ID.
Mary later resumes her tablet session and provides her email address while subscribing to your newsletter. Upon doing so, streaming ingestion adds a new identity as record data within her profile. As a result, Identity Service now relates Mary’s tablet device activity with her eCommerce account history.
By the next click on her tablet, your targeted content could reflect Mary’s full profile and history, rather than just a tablet used by an unknown shopper.
The identity relationships that Identity Service defines and maintains are leveraged by Real-time Customer Profile to build a complete picture of a customer and their interactions with your brand. For more information, see the Real-time Customer Profile overview.
An identity is data that is unique to an entity, typically an individual person. An identity such as a login ID, ECID, or loyalty ID is referred to as a known identity.
PII such as email address and phone number, serves to directly identify a customer. As a result, PII is used to match a customer’s multiple identities across systems.
Unknown or anonymous identities single out a device without identifying the actual person using it. This category includes information such as a visitor’s IP address and cookie ID. While behavioral data can be gathered from a device using unknown identities, associating these identities across devices or mediums is limited until your customer supplies PII during their journey.
As shown in the image below, known and anonymous identities are both important components of identity graphs, which are discussed later in this document.
Examples of Identity Service implementations include:
If you asked a person “What is your ID?” without any further context, it would be difficult for them to provide a useful answer. By the same logic, a string value representing an identity value, whether it is a system generated ID or an email address, is only complete when supplied with a qualifier that gives the string value context: the identity namespace.
You customers may interact with your brand through a combination of online and offline channels, resulting in the challenge of how to reconcile those fragmented interactions into a single customer identity.
The following video is intended to support your understanding of identities and identity graphs. The following video covers the three capabilities of Identity Collection, Identity Graphs, and the APIs. It also describes how deterministic and probabilistic algorithms are used to construct private identity graphs, and discusses the role of private identity graphs, Adobe Experience Platform Identity Service Co-Op Graph, and third-party graphs.
When your customer is interacting with your brand across multiple channels including web, mobile application, call center, or a storefront it can be difficult to understand and serve them if you cannot observe and track their activity across channels.
Understanding your customer across multiple devices and channels starts by recognizing them in each channel. Adobe Experience Platform achieves this by using identity namespaces.
An identity namespace is an identifier such as device ID or email ID used to provide the context from which data originates. Identity namespaces are used to look up or link individual identities, and provide context for identity values to prevent data collisions. For example, ID “123456” may refer to one person in your eCommerce system, and a different person in your help desk system. For more information, see the identity namespace overview.
An identity graph is a map of relationships between different identity namespaces, providing you with a visual representation of how your customer interacts with your brand across different channels.
All customer identity graphs are collectively managed and updated by Identity Service in near real-time, in response to customer activity.
Identity Service manages an identity graph visible by only your organization and built based on your data, referred to as the private graph. Identity Service augments your private graph when an ingested data record contains more than one identity, adding a relationship between the identities found.
As an example of the potential types of factors to consider when supplying and labeling identity data, using phone numbers such as “work phone” may result in more relationships than you intend in the identity graph. You may find many employees refer to the same number for work, and that “home” and “mobile” better serve to keep relationships as precise as possible.

This section covers how data provided to Adobe Experience Platform is processed prior to being used by Identity Service to build an identity graph for each customer.
Depending on your enterprise data collection strategy, the data fields you label as identities determine which data is included in your identity map. To get the maximum benefit of Adobe Experience Platform and the most comprehensive customer identities possible, you should upload both online and offline data.
Online data is data that describes online presence and behavior, such as usernames and email addresses.
Offline data refers to data that is not directly related to online presence, such as IDs from CRM systems. This type of data makes your identities more robust and supports data cohesion across your disparate systems.
While Experience Platform offers a variety of standard namespaces, you may need to create additional namespaces to properly categorize your identities. For more information, see the section on viewing and creating namespaces for your organization in the identity namespace overview.
Identity namespaces are a qualifier for identities. As a result, once a namespace has been created, it cannot be deleted.
As the standardized framework by which Platform organizes customer data, Experience Data Model (XDM) allows data to be shared and understood across Experience Platform and other services interacting with Platform. For more information see the XDM System overview.
Both record and time series schemas provide the means to include identity data. As data is ingested, the identity graph will create new relationships between data fragments from different namespaces if they are found to share common identity data.
Any field of type
string in schemas that implement either record or time series XDM classes can be labeled as an identity field. As a result, all data ingested into that field would be considered identity data.
Array and map type fields are not supported and cannot be marked and labeled as identity fields.
Identity fields also allow for the linking of identities if they share common PII data.
For example, by labeling phone number fields as identity fields, Identity Service automatically graphs relationships with the other individuals found to be using the same phone number.
The namespace of resulting identities is provided at the time the field is labeled.
During the streaming ingestion process, Identity Service automatically extracts identity data from record and time series data. However, before data can be ingested, it must be enabled for Identity Service. See the tutorial on configuring a Dataset for Real-time Customer Profile and Identity Service using APIs for more information.
The following video is intended to support your understanding of Identity Service. This video shows you how to label data fields as identities, ingest Identity data and then verify that the data has made it to the Adobe Experience Platform Identity Service Private Graph.
The Platform UI shown in the following video is out-of-date. Please refer to the documentation for the latest UI screenshots and functionality.
Adobe Experience Platform was built with privacy in mind and includes a data governance framework to protect your customer PII data. Identity data under the “email” or “phone” namespace is encrypted by default, but in order to ensure sensitive data is encrypted before it is persisted, data usage labels can be applied to data as it is ingested or once it arrives in Platform. For more information, please read the Data Governance overview.
Now that you understand the key concepts of Identity Service and its role within Experience Platform, you can begin to learn how to work with your identity graph using the Identity Service API.
