The Future of Blockchain

It is possible to use blockchain for more than only cryptocurrencies. This TRUSTECH conference featuring Infineon Technologies, Nxxtech & The Identity and Payments Association is about the future of this technology.

THE FUTURE OF BLOCKCHAIN

Blockchain has multiple applications besides bitcoin or cryptocurrency, and more and more industries start to think about using it.

Healthcare Identity and the Blockchain - An Architecture

Do we need an identity to successfully use blockchain? Blockchain is KPI with a certificate authority distributed. Scott Dueweke has been involved in this area for a long time. In 2008, he was working with a company on the dark web. Back then, there was no bitcoins but digital gold systems. He was contacted by a healthcare group wanting to do something with blockchain, but not really knowing what.
  

He set a “shark tank” up, composed by senior people from different parts of the organization. The goal was to think about what they could do with the blockchain in the group. Scott Dueweke also put the business leaders in the process. He realized that they were competing to know which part of the organization would have this proofy concept for the blockchain to be applied.
   

The conclusion was that they were focusing on something very precious: the identity. They had to decide if it would include IoT, medical devices, employees or patients, and decide if it would be about the people. They engaged an identity data provider, ID DataWeb, to be able to do biometrics and other things in that domain. They also developed a sandbox to start testing this out.
  

The architecture is about creating a registration authority for patients and employees, using the existing hospital infrastructure. Then it will be provided to ID DataWeb which will give a search capability to go out and check again a whole bunch of databases and create a checklist.
   

Once achieved, it will be transmitted to a third-party service provider as a token wrapped up and genesis-blocked for the blockchain and for the patients, before being put into the system. At the beginning, it will just be for ten hospitals, but afterwards it could be extended beyond that.
   

The US government smart card project had its system delayed because they forgot to do the identity registration authority in the best way. Any of this blockchain system that is doing IoT needs to be considered regarding of registration authority, which is a critical point.

Why Hardware Security is Essential for Secure Blockchain Applications

What would you do if you forget or lose your PIN number for debit card? In a normal system with a bank, you can ask for help to a central authority and the problem can be solved easily. But when you’re in a decentralized system, you have a problem because there’s no central authority, so no one can help. It’s very important to have the best protection of your user credentials in place.
  

Blockchain is a decentralized system with no central authority. Today, already 2100 different cryptocurrencies exist. There’s a high interest in this technology, and blockchain is here to stay but it’s not only about cryptocurrencies. It’s also about asset management, electronic systems, swimming application, energy sectors, insurance and health care.
   

Security is important for these systems, because if you lose your private key, all assets are lost in a way that you can’t really do anything with it. It makes no sense if you have a lot of money but can’t pay with it. If they were stolen, the attackers can do all they want with your assets, and blockchain transactions can’t be undone.
   

There are different attach classes, such as software attacks, micro architecture attacks or physical attacks. Companies must design a blockchain application with enough security. This is not only for bitcoin or human beings, but all devices willing to place objects on blockchain (consumers, smart home…).

Self-Sovereign Identity: New Dimensions of Secure Identity with the Blockchain

We all have the problem of remembering usernames and passwords. An increasing number of people have been hacked over the past years and it’s terrible. Companies must spend a lot of money to secure their infrastructures.
   

Log-in is one use-case of the development stack that Nxxtech created. Self-sovereign identity means that you’re the owner of your own data. Usually if you want to log-in to a company or a service account, you would have to use username and password. To avoid that, Nxxtech created an easy log-in procedure that uses blockchain.
   

With the GDPR, the user can define whether he wants to grant access to his data or not. Owning data is a very important concept. In shifting the trust layer to computers and machines that use cryptography to secure data, you have to almost trust this infrastructure. When you interact with your car or your printer, you are sure this is you and you are the only person who has authority to interact with them.
   

We want to share and connect with other people to have a meaningful life. We have to trust them. Customers are happy when their data are secured.
