building up a complete picture of a person, company or any entity is a challenging task. With different databases, systems and applications containing pieces of information about entities, making sense of those pieces and linking them together is a real headache. For example, how can we identify a single customer across multiple channels or platforms and provide a unified experience? Or, how can we verify the identity of an employee, contractor or partner across different workflows and systems to enforce access control policies? The answer lies in centralizing identity and master data.

What is identity?

Identity refers to the unique set of attributes or characteristics that describe a person, organization, device or any other entity. These attributes can include personal information (such as name, mailing address, email address, phone number, social security number), biometrics (such as fingerprint, facial recognition, voice recognition), behavioral patterns (such as browsing history, purchase history, social media activity), credentials (such as username, password, security token) and more.

Why centralize identity?

Centralizing identity means that all the identity data related to an entity is stored in a single location or repository, accessible by multiple systems and applications. By doing so, we can achieve the following benefits:

How to centralize identity?

Centralizing identity means creating and managing a single, authoritative source of truth for all the identity data related to an entity. This can be done by implementing a master data management (MDM) solution that serves as the central repository for identity. An MDM solution provides the following functionalities:

How to master data for better record linkage?

Master data refers to the set of homogeneous and structured data that describes the most important entities (such as customers, products, employees, etc.) of an organization. Master data includes key attributes such as name, address, date of birth, account number, etc., that serve as the primary identifiers for those entities. Master data is critical for record linkage because it enables the matching and linking of different instances of the same entity across different sources.

Why master data?

Master data serves as the core reference data for an organization. By maintaining accurate and consistent master data, we can achieve the following benefits:

How to master data?

Mastering data means creating and managing the unique identifiers and attributes that describe the entities of an organization. This involves the following steps:


Centralizing identity and mastering data are two important steps towards achieving better record linkage and data quality. By creating and managing a single, authoritative source of truth for identity and master data, we can provide consistent, efficient and secure access to those data for multiple systems and applications. This in turn, enables us to improve the customer experience, enhance the employee productivity and reduce the risk of data breaches and fraud. To get started with centralizing identity and mastering data, you can explore various MDM solutions available on the market, such as Informatica MDM, Talend MDM, or IBM MDM.
