Identities in real life. Claims on Sovrin blockchain.
In your daily life, you use identity-based claim requests and go through claim-check processes on a regular basis. These requests and claims often seem so natural that people often do not even notice them or the process that occurs when third parties check the claims.
For example, when you arrive at an airport for your flight, you don’t simply show your driver’s license or passport and go to the plane. You can’t do that because if this was the case, then any person with a driver license would be able to get onto the plane and the airlines would be sorting out the mess of trying to figure out who should be flying on the plane and who doesn’t belong there.
So that this mess doesn’t happen, you can’t get onto a plane right away. You first need to check in either online or at a ticket counter. You do that typically by entering the information about your driver license or your passport or by presenting one of these documents in person. By doing so, you are in essence making a claim that you are the person whose identity is described on the document. A clerk or a TSA agent verifies that the identity you have presented is valid and that your face matches the picture on the identity document. They also verify your claim that you have paid for the flight by either checking the validity of your boarding pass or looking you up in their database. In addition to this, the government checks the identities against multiple databases it has, such as the No Fly List. You can read more about the list on the official website of the Transportation Security Administration here: https://www.tsa.gov/blog/tags/no-fly-list
Assuming everything works fine and the airline and the government verifies your claims about your identity and your right to be on the plane successfully, you get to go to the gate and board the plane.
A boarding pass is a document that contains a lot of information that you may not notice right away if you do not pay attention. It has your name. It has your boarding priority. It has the flight number and departure time. It may also have your seat number.
In essence, a boarding pass is a collection of claims that the airline chose to make about you after you paid for your flight. Some of these claims are:
– you have a right to board a particular fight
– you have a right to do so in a particular window of time. If you are early, you will have to wait and if you are late, your flight will leave without you
– on the flight, you can seat at a particular seat.
None of the people involved in the process of making and verifying these claims have to think much about them. They simply check your boarding pass, point to your gate or your seat on a plane, and let you proceed.
It is also important to note here that nobody cares about how you obtained your set of claims stated on your boarding pass. You could have printed it at home yourself, received it from an automated kiosk or from an agent who has helped you in person. It doesn’t matter how you obtained the document. What matters is that the document is authentic and represents the claims accurately.
On computer networks, such as sets of claims are known as security token.
Claims on blockchain networks
Each claim has a digital signature, so anyone on a blockchain network would know who originally has created the claim and what has happened to the claim since its inception.
Claim use and management is where the power of blockchain technology could revolutionize many industries and fields.
For example, according to article in the Inc Magazine from August of 2017, 85% of people lie on their resumes.
Why do they do it? The short answer is, because it often go unnoticed. In many instances, companies do not have sufficient resources to check every claim an applicant makes on a resume. The world of business is also very disjoined and even when a person applies to multiple jobs in the same geographical industry or area, there is currently no way for companies to see the resumes that an applicant is submitting to other companies and spot the lies.
