Blockchain or PKI for digital identity?

What is Identity?

The combination of physical, biometric, social and documented data about the person. All these things together give a person a unique identity.

What is a digital identity (eID)?

Digital identity is your electronic ID-card that proves your identity on the internet. It has many levels and forms but the strongest digital identity is connected with your physical identity. This is more like basic identity what you must have and all other identity schemes are based on it. But digital identity usually contains more information than a unique combination of letters and number which is your personal identification code. It might include your name, email address, the name of the organization that issued it, a serial number, and an expiration date.

What are the current problems with digital identity?

Most of the people in the world have already some kind digital identity, but it is not secure or it’s secure but not strongly connected with their physical identity.

What are the advantages/disadvantages of putting an identity on blockchain in the world where personal identification code and identity is issued by states?

Advantages: There are no clear advantages if the idea and concept is to replace the current solution.

Disadvantages: It will just replace email, which is currently used as ID, or the current unique identity number, which is issued by the various organisations or states and it is owned by the state, not by the citizen.

What are the challenges of putting an identity on blockchain?

No challenges. It’s a just technology and we can use it for replacing current unique identification number what we have. And we all have it and it’s given to us by the state authorities.  It’s a more question of the purpose why you need to have a digital identity and for what you will use it. Let’s think that we need it for online channels and three main purposes are identification, authentication and document signing. So we have now Digital ID which is based on the blockchain and issued by the trusted authorities.  Done. What else? We need to use it in online channels for identification, authentication and document signing.

Done. We will use traditional PKI technology and we can do it. (I don’t know currently any better technology for it. If somebody knows then please let me know. We are not gonna use blockchain PKI with simple reasons. It can be used only for offline usage. No real-time identity verification by the trusted body. ) Now we have a working solution.

How difficult will SaaS be to use, configure and upgrade?

Since SaaS vendors face heavy competition, they make a point of providing software that is as easy as possible to use and configure. Many even offer the option to try out the software for a limited time before you make a purchase, so you can see for yourself what you will be subscribing to. While not all SaaS programs offer as much ability to poke around “under the hood” as traditional on-premises software does, they make up for that core simplicity with a wide variety of integration options and add-ons.

SaaS tools typically come pre-loaded with examples, best practices and even detailed walkthroughs. Once your team learns the basic interface of a SaaS program, they will always have expert support just a click away. That means you won’t lose costly hours of project time while a team member waits for help from a local IT worker. Even new features and updates typically come with built-in guides and step-by-step assistance – all rolled out at the same time, across every computer on your subscription.

When considering a switch from traditional on-premises software to SaaS, be sure to factor the full range of costs into your calculations. Local software may initially appear to cost less, until you include the salaries of in-house IT staff, the costs of servers and hardware upgrades, storage media for backups and hours spent trying to get the data to integrate across old and new systems. Once you weigh up all these factors, SaaS typically works out to be far more cost-effective – especially over the long term – than on-premises software and hardware would be.

For all of these reasons – and many more – cloud-based electronic identity gateway SignWise Services, are a crucial component of any modern human resources department for a company of any size.

How is this approach different from the current solutions where every citizen has already unique identification number?

No matter which currently known solution you are using, the end result will be the same: Every citizen will get a unique combination of letters and number which is your personal identification code.  It Makes No Difference.
