Blockchain Could Help Us Reclaim Control of Our Personal Data

It’s a strange world we live in when large companies such as Experian, Equifax, and TransUnion are able to store huge quantities of our personal data and profit from it in a way that doesn’t always benefit us. And when those same companies lose our personal data and make us susceptible to identity theft, there’s virtually nothing we can do about it. Equifax lost the data of more than 140 million people, and recompense is not forthcoming. Meanwhile, the CEO may be stepping down with a pension worth $18 million. Clearly, the system is broken, and it’s time to stop and ask ourselves why we continue to rely on a system that doesn’t stand up to the challenges we face in a digital society.

Credit-referencing agencies benefit immensely from our data, but there are many other data privateers — from online shopping sites to retailers to media firms – that are doing the same, including our own governments. U.S. Social Security numbers, or UK National Insurance numbers, were originally created to keep track of the earnings history of workers for entitlement and benefit programs. Both have since morphed into critical numbers assigned at birth that can be used by government agencies not just to collect taxes, but to identify individuals. They are also now used by private industry to track our financial and commercial histories.

Many countries have such a national identity system. With the governments of China and India both providing their citizens a national identity (Hukou in China and Aadhaar in India), it’s safe to say that well over a third of the world uses government-issued identitifiers. Among the various ways to prove identity, the U.S. stands out for its complexity, relying on a mix of varying state mechanisms — for example the ubiquitous use of state driving licenses, combined with Social Security numbers. A decade ago, the UK attempted to establish a national identity system, which was ultimately scrapped for many reasons, which included political overreaching, lack of security, and cost overruns. None of these nation’s systems have proven to be a practical, reliable way to protect and prove our identities.

Still, numerous smaller countries, such as Singapore, are exploring national identity systems that span government and the private sector. One of the more successful stories of governments instituting an identity system is Estonia, with its ID-kaarts. Reacting to cyber-attacks against the nation, the Estonian government decided that it needed to become more digital, and even more secure. They decided to use a distributed ledger to build their system, rather than a traditional central database. Distributed ledgers are used in situations where multiple parties need to share authoritative information with each other without a central third party, such as for data-logging clinical assessments or storing data from commercial deals. These are multi-organization databases with a super audit trail. As a result, the Estonian system provides its citizens with an all-digital government experience, significantly reduced bureaucracy, and significantly high citizen satisfaction with their government dealings.
