Self-Sovereign Identity and Verifiable Credentials in Your Digital Wallet
Mary Lacity, Erran Carmel
This paper provides an overview of Self-Sovereign Identity (SSI), a decentralized approach for issuing, holding, and verifying digital credentials. Through an analysis of the technology's architecture and a case study of the UK's National Health Service (NHS), the authors explain SSI's business value, implementation, and potential risks for IT leaders.
Problem
Current digital identity systems are centralized, meaning individuals lack control over their own credentials like licenses, diplomas, or work histories. This creates inefficiencies for businesses (e.g., slow employee onboarding), high costs associated with password management, and significant cybersecurity risks as centralized databases are prime targets for data breaches and identity theft.
Outcome
- Self-Sovereign Identity (SSI) empowers individuals to possess and control their own digital proofs of credentials in a secure digital wallet on their smartphone. - SSI can dramatically improve business efficiency by streamlining processes like employee onboarding, reducing a multi-day manual verification process to a few minutes, as seen in the NHS case study. - The technology enhances privacy by enabling data minimization, allowing users to prove a specific attribute (e.g., being over 21) without revealing unnecessary personal information like their full date of birth or address. - For organizations, SSI reduces cybersecurity risks and costs by eliminating centralized credential databases and the need for password resets. - While promising, SSI is an emerging technology with risks including the need for widespread ecosystem adoption, the development of sustainable economic models, and ensuring robust cybersecurity for individual wallets.
Host: Welcome to A.I.S. Insights — powered by Living Knowledge, the podcast where we translate complex research into actionable business strategy. I’m your host, Anna Ivy Summers. Host: Today, we’re diving into a study from MIS Quarterly Executive titled "Self-Sovereign Identity and Verifiable Credentials in Your Digital Wallet." Host: It explores a decentralized approach for managing digital credentials, analyzing its business value, how it's implemented, and the potential risks for today’s IT leaders. Here to help us unpack it is our analyst, Alex Ian Sutherland. Welcome, Alex. Expert: Great to be here, Anna. Host: Alex, before we get into the solution, let's talk about the problem. Most of us don't really think about how our digital identity is managed today, but this study suggests it's a huge issue. What’s wrong with the current system? Expert: The problem is that our digital identities are completely fragmented and controlled by others. Think about your physical wallet. You have a driver's license, maybe a university ID, a credit card. You control that wallet. Online, it’s the opposite. Your "credentials" are spread across countless organizations, each with its own username and password. Expert: The study points out that the average internet user has around 150 online accounts. For businesses, managing all these separate identities is inefficient and incredibly risky. These centralized databases of user data are what the study calls "honey pots," making them prime targets for data breaches. Host: So it's a headache for us as individuals, and a massive security liability for companies. Expert: Exactly. And it’s expensive. The research mentions that a single corporate password reset costs a company, on average, seventy dollars. When you scale that up, the costs become astronomical, not to mention the slow, manual processes for things like employee onboarding. Host: So, the study explores a new approach called Self-Sovereign Identity, or SSI. How did the researchers go about studying this emerging technology? Expert: This wasn't a lab experiment. The authors spent two years deeply engaged with the communities developing SSI. They interviewed leaders and conducted detailed case studies of early adopters, most notably the U.K.’s National Health Service, or NHS. This gives us a real-world view of how the technology works in a massive, complex organization. Host: That NHS case sounds fascinating. Let's get to the key findings. What is the big idea behind Self-Sovereign Identity? Expert: The core idea is to give control back to the individual. With SSI, you hold your own official, verifiable credentials—like your university degree or professional licenses—in a secure digital wallet on your smartphone. You decide exactly what information to share, and with whom. Host: So instead of a potential employer having to call my university to verify my degree, I could just prove it to them directly from my phone in an instant? Expert: Precisely. And that leads to the second key finding: a dramatic boost in business efficiency. The NHS, for example, processes over a million staff transfers between its hospitals each year. The old, paper-based onboarding process took days. The study found that with an SSI-based "digital staff passport," that process was cut down to just a few minutes. Host: From days to minutes is a huge leap. But what about privacy? Does this mean we're sharing even more personal data from our phones? Expert: It’s actually the opposite, which is the third major finding: enhanced privacy through what's called 'data minimization'. The study gives a classic example: proving you're old enough to buy a drink. Right now, you show your driver's license, which reveals your name, address, and full date of birth. The bartender only needs to know if you’re over 21. Expert: With an SSI wallet, you could provide a verifiable, cryptographic proof that simply says "Yes, this person is over 21," without revealing any of that other sensitive data. You only share what is absolutely necessary for the transaction. Host: That's a powerful concept. So for businesses, the value is efficiency, but also security, right? Expert: Right. That's the final key finding. By moving away from centralized databases, companies reduce their cybersecurity risk profile. They are no longer the 'honey pot' for hackers. It removes the liability of storing millions of user credentials and cuts the operational costs of things like password management. Host: This all sounds truly transformative. Let's focus on the bottom line. What are the key takeaways for business leaders listening today? Why should they care about SSI right now? Expert: The most immediate application is for streamlining any business process that relies on verifying credentials. We saw it with employee onboarding at the NHS, but this could apply to customer verification in banking, compliance checks in supply chains, or membership verification. Host: And it seems like a great way to build trust with customers. Expert: Absolutely. In an era of constant data breaches, offering your customers a more private and secure way to interact is a significant competitive advantage. But the study is also clear that this isn't a silver bullet. It's an emerging technology. Host: What are the main risks businesses need to consider? Expert: The biggest challenge is ecosystem adoption. For SSI to be truly useful, you need a critical mass of organizations issuing credentials, and organizations accepting them. There are also still questions to be solved around sustainable economic models and ensuring the security of the individual's digital wallet is foolproof. Host: So it's a long-term strategic play, not something you can just switch on tomorrow. Expert: Exactly. The study’s key advice for leaders is to start learning and exploring this space now. An interesting tip from the NHS project was this: when you talk about it, focus on the business problem you're solving—efficiency, security, and trust. That's what gets buy-in. Host: Alright, Alex, let’s wrap it up. To summarize, the current way we manage digital identity is inefficient and insecure. Self-Sovereign Identity puts control back into the hands of the individual through a secure digital wallet. Host: For businesses, this means faster processes, lower cyber risks, and a powerful new way to build customer trust. While it's still early days, now is the time for leaders to get educated and start planning for this shift. Host: Alex, thank you so much for breaking down this complex topic for us. Expert: My pleasure, Anna. Host: And thank you to our listeners for tuning into A.I.S. Insights, powered by Living Knowledge. Join us next time as we explore another big idea shaping the future of business.
