Identity management is a complex process and its implementation can be tough. The concept of reusable identity has made this process easier by Bahaa Abdul Hadi for quick understanding.
What is reusable identity?
Reusable identity allows users to grant access without having to secure and manage the identity components. A key benefit of reusable identity is that it does away with repetitive processes.
In the real world, people have identity cards that are used to authenticate their identity. In the digital world, users would have credentials like a user id and password. They would need to use it to verify their identity. The problem is that there are multiple platforms and each have their own credentials.
Reusable identity allows users to have a single credential to access any platform. It offers convenience for users and robust security for platforms.
Studies show that the reusable identity market would grow sevenfold over the next 5 years. It is estimated that in 5 years the market size would grow from $32 billion to $270 billion.
Benefits of reusable identity
The biggest benefit of reusable identity is standardization. Reusable identity allows organizations from different spheres to use a single identity. Whether it is government or a small business, the same identity can be used for authentication.
NIST, the US standard body has introduced a digital guideline that offers standard for digital identity. More such standards are likely to be introduced making it easy to standardize reusable identity.
A single identity that can be reused in different platforms offers convenience for users. Many users forget their passwords because of multiple identities. In such a scenario, a single reusable identity is highly convenient.
A reusable identity ensures users have to share their personal data only once. In the present situation, they need to share the data with every platform. A reusable identity gives them more privacy and security.
It offers convenience even for service providers. They don’t have to worry about storing user identity data and validating it. They can follow the common standard for authentication. It makes their compliance to laws easy.
Though there are many benefits, there are challenges too. Lack of trust is an issue with many users distrusting a single common ID. There are also security concerns and if a hacker gains access to the one ID, they can hack into multiple accounts. It is important to develop stringent standards that ensure a highly secure system for reusable identity.
