Employee badges need to be swiped many times throughout the day in order to access the building, parking garage, conference rooms or elevator floors. Accessing computer systems at work also requires validating one’s identity. College students also have to swipe their IDs to access to their dormitories.
Imagine replacing that badge with a reusable identity certification on a blockchain that has been linked to corporate systems. It would be far simpler for the employer, who no longer has to cut access or worry about retrieving credentials. This new model only has to revoke access on the blockchain and automatically update eligibility all at once.
There are many situations where we act on someone else’s behalf and need to prove multiple things. Who we are, who the other person is, nature of our relationship, legal standing to intervene, and the other person’s eligibility for whatever we’re trying to access. Only then do we get to interact with nurses, social security, and so on. Similarly, even simple things such as filling out school forms or dealing with doctor appointments require us to prove identity, relationship, and legal status. Let’s imagine a system where all this information automatically available and updated. We would be able to help others without having to constantly prove our identity.
Many of us have grown up with library cards, so we think of them as one piece of identity. They actually are a combination of multiple pieces of information, which prove that:
The library re-validates the data regularly to ensure continued eligibility. However, the first two components are already incorporated into blockchain identity systems. The third piece could easily be added as a claim by the library instead of the library having to continue with its own system.
Other common services offered to town residents, like permit parking, also require to link your identity to an asset like a car. The town would benefit from being able to streamline identity management, because all of the separate systems for managing identity would be eliminated.
Like employees, students also carry specific badges that grant them access to the cafeteria, to school property, borrow or use school equipment, etc. Like previous examples, that badge validates identity, residency (for public schools,) and eligibility.
It may not seem like these are massively world-changing uses for portable, cross-domain identity. But that is actually the point. No technology changes the world until it changes our daily lives. These mundane but common use cases are exactly the way many of us will begin to use digital identities that leverage blockchain technology. We will benefit from simplifying our daily lives while protecting ourselves from identity theft, fraud and other issues with identity data.
