Blockchain and Digital Identity

Technological advancements in the digital space has revolutionized every aspect of our lives, from shopping to collaborating with colleagues to keeping in touch with friends to entertainment to managing our finances. Since the dawn of the Internet, identity management has been a key concern, with billions of dollars being spent on usability, security and privacy.

The identity and access management market is expected to grow from $8.09 billion in 2016 to $14.82 billion by 2021, representing a 12.9% CAGR. Despite this huge investment, managing digital identities continues to be plagued by three Cs — Cumbersome, Costly and Challenging.

With data driving the world today, digital identity is critical to most business and social transactions. This governs the interaction of users in the digital world. But traditional identity systems continue to be highly vulnerable, with single points of failure, attracting continuous attempts to gain access to the complete repository of high value data.

And, with companies prioritizing cybersecurity, identity protection and compliance management, while customer experience is significantly compromised. As individuals, we shoulder the burden of managing multiple online IDs and passwords, while also handling a host of documents, including passports, driver’s licenses, Social Security cards and medical insurance cards.

Blockchain has evolved significantly from the distributed ledger technology created to track bitcoin ownership. This technology can replace traditional systems with a highly trusted mechanism of managing identities. Blockchain can empower users to have greater control over their own identity. Organizations can use the information only with customers’ consent and no central entity would be able to compromise a consumer’s identity.

Blockchain has facilitated the so-called self-sovereign identity, which is inherently unalterable and more secure than traditional identity systems.

This has the potential to completely change the way we use identities to connect to different online services. Individuals would use their self-sovereign ID to verify their identity, removing the need for passwords. As with every lifechanging innovation, there’s been an extended period of evolution, with experts exchanging ideas and little consensus on what self-sovereign ID means!

It’s a concept that stems from the belief that an individual must have control over the administration of his identity. The ID cannot be locked into one site and there needs to be interoperability of the ID across multiple platforms, with user consent. Experts have been contemplating the summation of various identifying information like demographic and employment related data and even information about the individual revealed by other people.
