  • A Solution Looking for a Problem? Digital ID Solves a Million of Them 2022-08-09 David Birch, Forbes

    The general problem statement here is, as you will have noticed, not about proving who you are but about proving what you are. I need to know you have a line of credit, a pilot’s licence or a diploma from a top ten dental school. I do not care who you are, unless something goes wrong, it which case law enforcement or professional bodies take over.

    Here, then, there is most definitely a problem looking for a solution and we already know what the solution is: verifiable credentials (VCs).

  • Digital Identity Isn’t Only For People 2020-12-22 David Birch, Forbes

    fintechs and regtechs looking for opportunities in the digital identity space should cast their ideas net pretty wide. Digital identities are not only for people and the future desperately needs digital identities for pretty much everything to underpin recognition, relationships and reputation (the 3Rs of the online economy).

  • SSI Essentials: 35 use cases of decentralized identities that will make your life easier 2022-04-07 Gataca

    It is not farfetched to assume that we all strive to perform routine activities in the most simple and efficient way. This can include relatively easy activities such as logging in to your student/employee portal and shopping online or slightly more complex activities such as opening a bank account, renting an apartment, or applying to a master’s program or job.

  • How to Convince Dad* of the Importance of Self-Sovereign Identity *and your sister and your daughter and your best friend and your nephew 2018-12-12 rwot7

    This paper addresses that need by offering arguments to a variety of people who might be reluctant to use self-sovereign identity, uninterested in its possibilities, or oblivious to the dangers of centralization. By focusing on the needs of real people, we hope to also encourage developers, engineers, and software business owners to create the apps that will address their reluctance and fulfill their needs, making self-sovereign identity a reality.

  • Coming soon — a resume-validating blockchain network for job seeker 2022-10-05 Computer World

    “Verifying applicant career records can take days, weeks, if not months, to complete,” said Dror Gurevich, founder and CEO of the Velocity Network Foundation. “Hiring methods are severely outdated to the point that one in three Americans have admitted to lying on their resumes, which slows the hiring process immensely.

  • How Blockchain Technology and Self-Sovereign Identity Enables the New Normal of Remote Learning, Training and Working 2022-08-06 Md Sabbir Hossain

    This model lets the identity owner easily organize a unique, verifiable learning path from a wide variety of resources to powerfully prepare for a particular job. Similarly, employers can encourage job candidates to complete recommended learning paths for certain roles, ensuring that they enter the organization with the right skills and verifiable competencies. Or, employers can upskill employees by designing curriculums that draw upon a diverse variety of online courses, university or community college programs, coding academies, or other competency evaluation frameworks. Any course that is completed, a certificate that is earned, or work experience that is gained will produce a verifiable credential that can be shared with any other entity that uses a compatible self-sovereign identity system.

  • Trusted Career Credentials 2022-02-11 Dr Gordon Jones

    Today, even in this digital world that has expanded over the past two years, the job market still relies on self-reported attributes, records, resumes, and/or LinkedIn profiles, that individuals share with employers or recruiters as the source for applicants and employee data.

  • Blockchain and the Decentralised Workforce 2021-05-01 WorkforceFuturist

    For workers, life-long learning will be a big theme and there will more opportunities to earn and learn. We will ditch the CV/resume and use digital credential wallets, as we will for other personal data e.g. health, financial, identity. There will be greater competition for our time and attention, where work and leisure overlap.

  • Self sovereign career identity 2020-11-16 Meg Bear Diginomica

    The Velocity piece is a way for me as an individual to own my credentials, to say, these are the things that I know. And these are the things I’ve done. And if I can own that, I have a lot more interest in it. And I can use it in a lot more interesting ways. In the past, that might have just been something that I built as reputation within a company, I can now make that a more dynamic and portable reputation I can take with me anywhere.

    This could then act as a form of universal Verifiable Credentials (VCs) that would be acceptable for any platform to confirm who someone is but wouldn’t give access to any information that an individual elected to restrict. As an individual demonstrates experience, earns certifications, or expands their credentials, this digital identity would instantly reflect that, evolving an online reputation.

Besides, we present an architecture for constructing and customizing SSI services with a set of architectural patterns and provide corresponding evaluations. Furthermore, we demonstrate the feasibility of our proposed architecture in practice with Selfid, an SSIaaS platform based on our proposed architecture.

  • Credentials as a Service Providing Self Sovereign Identity as a Cloud Service Using Trusted Execution Environments 2021-10-04 Hira Siddiqui, Mujtaba Idrees, Ivan Gudymenko, Do Le Quoc, Christof Fetzer

    With increasing digitization, more and more people use their identification credentials for accessing online services; which increases concern for data privacy. To ensure user’s privacy, alternate credential management schemes must be adopted. Self-Sovereign Identity (SSI) is a form of credential management where users are in charge of their credentials. Privacy-critical data is stored at the user’s end and they can choose to do selective disclosure of minimal required information to access services. Currently, SSI solutions are not being widely adopted by service providers and the ecosystem is fragmented. One of the reasons for the lack of adoption is the need for maintaining private infrastructure for credential issuance, as critical user information is to be handled during credential issuance. To cater to this, we present a solution that enables the service providers to run their credential issuers on public cloud - a so-called Credentials as a Service (CaaS). CaaS issuers run inside Trusted Execution Environments (TEE) enabling credential issuers to ensure user’s privacy while enjoying the flexibility of the pay-per-use cloud model. CaaS can pave the way for making SSI credentials ubiquitous in identity management solutions.

Second, the smart contracts are used to negotiate the secure transfer of real estate property deeds on the marketplace. To assess the viability of our proposal we define an application scenario and compare our work with other approaches.

    Why? Because the pieces of evidence that administrative agencies require to register property — things like a survey plan, a notarized will, or a state-issued identity card — may be inaccessible, or may not represent the reality of rights on the ground. As a result, land administration systems end up excluding billions of people.

    Our interest in identity systems was an inevitable outgrowth of our earlier work on blockchain-based1 land registries.2 Property registries, which at the simplest level are ledgers of who has which rights to which asset, require a very secure and reliable means of identifying both people and properties. In the course of investigating solutions to that problem, we began to appreciate the broader challenges of digital identity and its role in international development. And the more we learned about digital identity, the more convinced we became of the need for self-sovereign identity, or SSI. This model, and the underlying principles of identity which it incorporates, will be described in detail in this paper.

  • What does it take to develop human-centric solutions for the built environment? 2022-05-13 MyData [Video]

    Building better, more human-centric solutions in smart cities starts by realising that citizens and their digital footprints are not merely aspects to monitor and evaluate. They are active participants in the cities we live and work together and need to be engaged in designing better cities and managing the data about themselves. This is not important only for respecting citizens’ rights, but it is crucial to building sustainable services and humane cities.
