Understanding the Future Identity Management System: Blockchain and Biometrics.

In this segment, we are going to understand the integration of the Biometric system with Blockchain and how it is going to work.

Blockchain is an innovative technological improvement which is implemented specifically to guarantee information of people or corporations stays secure. It is a decentralized database that is made secure using cryptography. This implies that important information doesn’t have to go through centralized data collectors, be it private associations or the government. Access to the information inside the decentralized framework is constrained by the person who claims the information and they can decide to share it as they see fit. Incorporating this progressive innovation with biometrics can open up unique, more secure roads for identity management and security. It can end up being a viable method to avoid being a victim of cyber cheatings, intercepting the information and hacking, which are getting progressively pervasive in the present internet-connected world. 

The potential that blockchain provides to individuals is that it can give them back responsibility for important and sensitive information to a serious huge degree. With privacy concerns in abundance, blockchain-based biometrics can ingrain a reestablished stance that all is good among shoppers and enterprises. Furthermore, biometrics identity frameworks can likewise make protracted procedures spinning around identity confirmation a lot less difficult, which gives users responsibility for another benefit they miss out on routinely i.e. time.

Physical identity confirmation records, for example, driving license, Passport, and Aadhar card are basic needs to complete probably the most fundamental tasks. But, in a technologically propelled existence where AI is fit for reserving café spots for us, move around physical copies of our IDs. Moreover, ID verification at spots, for example, the airport, hotels, banks and more are in every case very long. Making yourself present at the airport an hour before residential flights and 2-3 hours before international flights appear to be a huge exercise. To give an increasingly seamless occurrence, different airports and banks are starting to consolidate or implement ID verifications with biometrics technology.

Also, we are now observing significant coordination of biometrics in digital Wallets, for example, Google Pay, banking applications, and even our workplaces! This guarantees you don’t need to continue entering card or record data more than once to make transactions. In workplaces, there’s not, at this point a need to keep physical indexes of registration and looking at Biometrics deals with that and guarantees that untrustworthy practices, for example, a companion using your organization card to swipe in your attendance in the workplace doesn’t happen.

In any case, the question that emerges with biometric arrangements are – Where is my information stored? Is it secure? Would it be able to be hacked? Would someone be able to use my biometrics information to approve store or resource moves? The appropriate response is true ‘yes’. To infuse a solid portion of security, transparency, and trust into biometrics, blockchain technology can end up being very encouraging.

The present identity management model in many situations is completely based on centralized cloud storage principles. It clears away for malicious risks by cybercriminals or hackers. If the cloud storage has some vulnerabilities (and nearly everything is vulnerable), hackers can figure out how to get hold of your important identity information. The biometric information stored on centralized databases likewise has third-party vendors which further builds the risk to privacy. With regards to online transactions, and identity management framework, for the most part, comprises an end-client, a service provider, an identity provider. As partners scale in number so does the chances of information breach risks. Not only do partners and cybercriminals represent a risk, but however AI is also additionally arriving at a phase of improvement where it fools biometric frameworks. If a hacker discovers a way into the centralized databases that store biometric information, they could use AI to make synthetic fingerprints and use them. Thus, there is a requirement for the biometrics ID framework to be infused with a portion of security and transparency which can be introduced by blockchain.


Tapping the capability of blockchain can change biometric ID frameworks by making them essentially more secure. Blockchain technology uses solid encryption methods to keep the information secure in decentralized records that must be accessed by those who are the one in power, or if the trustworthy figures have allowed others to get to. There are no middlemen right now in this technology and it additionally has lower operational expenses than centralized databases too. By removing partners or mediators, complex transactions are made boundlessly less complex between the sender and receiver, which spares time and the non-appearance of third party vendors which makes it considerably progressively secure. Members on the blockchain system can use biometric identification systems with low transaction costs, the absence of middlemen and higher processing power. Consolidating these two technologies implies that big tech companies can create consistent solutions for identity management and verification that guard the ID information in a distributed decentralized framework. With blockchain, client information is stored in distributed databases – which means all the information from different people is not kept together. This implies there is no single point of failure in this system. In this manner, cybercriminals are less inspired to independently get identity information stored in different ledgers. These advancements which take into consideration self-sovereign identity management can be deployed by government offices, institutions and organizations.!!

Moreover, our cell phones have a huge amount of biometric information stored in them. Online fraudsters are progressively finding innovative techniques to gain unapproved access to this information. Combined with the 5,000 investigated security flaws in cell phones operating systems and technologies like Bluetooth which can likewise give the hacker access to your cell phones, the cyber risks are rising day over day. Block chain-based cell phones are present in the market and are being grown more as the blockchain technology turns out to be progressively mature. These cell phones can keep away cyber attacks by cybercriminals to gain access to biometric information since the information is stored in the blockchain itself. Blockchain is an immutable technology, therefore unapproved modification is not possible which keeps our important biometric information secure.

With blockchain implemented biometrics identity frameworks, the approved individual has full access to the decentralized, distributed ledger and can likewise effectively see who gets to and shares the information inside the ledger.
